主要更新

插件系统

• 新增版本化插件 API 与独立工作进程；支持插件设置、传感器、概览读数、页面替换、风扇后端和插件自绘 WPF 页面。
• 可从插件页安全导入 ZIP：校验文件路径、链接、重复项、清单和解压大小；新导入插件默认停用，审核权限后才能启用。
• 支持插件设置分组、分别选择概览/OSD/记录使用的插件传感器、传感器历史曲线范围，以及带来源信息和频率限制的插件提示。
• 新增安全卸载和待卸载清理流程；如果插件 DLL 正在使用，Toolkit 会在安全重启后完成清理。插件示例单独构建，不包含在正式发布包中。

界面和硬件行为

• 插件页面和设置对话框跟随主题及中英文设置；传感器和概览布局在插件读数变化时保持稳定。
• 新增开机时恢复上次确认的键盘背光亮度；OSD 可通过显示器 EDID 身份在 GPU 路径变化后恢复到原屏幕。
• 传感器记录改为后台压缩，异常退出后可恢复已关闭的记录文件；每个记录使用唯一文件名，压缩失败时保留源文件。
• 驱动更新安装进入跨页面共享队列；辅助进程增加运行时限。
• 功耗锁定保留用户请求值和硬件确认值；读取验证后的固件钳制结果，避免反复覆盖硬件限制。

集成与安全

• 移除内置本机 HTTP 数据/控制接口；Toolkit 不再监听本机端口。需要集成时使用经过审核的插件 API。旧版联动设置会被忽略。
• 插件是可信代码模型，并非恶意代码沙箱。普通插件逻辑运行在独立进程；带 ui.custom 权限的 WPF 页面和风扇后端会在 Toolkit 进程中运行。只启用审阅过的插件。

下载

• ThinkBookToolkit-1.1.0-Setup.exe（推荐）：在线安装程序，可选择安装位置；检测不到 x64 .NET 9 Desktop Runtime 时会下载微软官方运行时，并注册 Guardian 服务和 UIAccess 自签名证书。
• ThinkBookToolkit-1.1.0-win-x64-framework-dependent.zip：便携版，需要系统已安装 x64 .NET 9 Desktop Runtime；不会自动注册服务或信任证书。
• SHA256SUMS-v1.1.0.txt：发布文件的 SHA-256 校验值。

安装和退出前请正常退出 Toolkit，让风扇恢复自动控制。Toolkit 使用项目自签名证书，不代表商业 CA 签名或 SmartScreen 信誉。公开发布包不包含 Lenovo Vantage/电脑管家的专有 DLL；NVAPI、Intel MMIO 和 AMD ZenStates 功耗功能仍为 Beta。

软件版本为 1.1.0，插件 API 版本为 1，可替换风扇后端 API 版本为 1.1，配置文件格式版本为 1.0。

Highlights

Plugin system

• Added a versioned plugin API and isolated worker processes. Plugins can provide settings, sensors, Overview rows, page replacements, fan backends, custom WPF pages and attributed toasts.
• Added ZIP import validation for paths, links, duplicates, manifests and expanded size. Imported plugins are disabled until reviewed and enabled.
• Added setting groups, independent plugin-sensor selection for Overview/OSD/recording, plugin chart bounds and safe plugin removal with deferred cleanup for loaded assemblies.
• The sample plugin is built separately and is not included in public release packages.

Interface and hardware behavior

• Plugin pages and setting dialogs follow the selected theme and language. Sensor and Overview layouts remain stable as plugin values change.
• Added startup restoration of the last confirmed keyboard-backlight level. OSD monitor placement can follow validated EDID identity across GPU-path changes.
• Sensor recordings are compressed in the background and closed files can be recovered after an interrupted session. Unique file names prevent collisions; failed compression retains its source.
• Driver installations continue in a shared queue when navigating away. Helper processes now have execution time limits.
• Power locks preserve the requested target separately from confirmed hardware values and accept verified firmware clamps without repeatedly fighting the hardware.

Integration and security

• Removed the built-in localhost HTTP data/control listener. Toolkit no longer opens a local port; use reviewed plugins for integration. Existing HTTP integration settings are ignored.
• Plugins are trusted code, not a malicious-code sandbox. Ordinary plugin logic runs in a separate process; WPF pages granted ui.custom and fan backends run inside Toolkit. Enable only code you have reviewed.

Downloads

• ThinkBookToolkit-1.1.0-Setup.exe (recommended): online installer with a selectable destination. Downloads the official Microsoft x64 .NET 9 Desktop Runtime when required and registers Guardian and the project's self-signed UIAccess certificate.
• ThinkBookToolkit-1.1.0-win-x64-framework-dependent.zip: portable package; requires the x64 .NET 9 Desktop Runtime. It does not automatically register services or trust certificates.
• SHA256SUMS-v1.1.0.txt: SHA-256 checksums for the release assets.

Exit Toolkit normally before installation so it can restore firmware automatic fan control. This version uses a project self-signed certificate, which does not imply commercial CA trust or SmartScreen reputation. Public packages do not include proprietary DLLs from Lenovo Vantage or Lenovo PC Manager. NVAPI, Intel MMIO and AMD ZenStates power controls remain Beta features.

The application version is 1.1.0, the plugin API version is 1, the replaceable fan-backend API is 1.1, and the configuration-file format is 1.0.

Before requesting after-sales service, uninstall ThinkBook Toolkit or remove the drive containing it to avoid unnecessary complications.

Highlights

Isolated GPU monitoring and recovery

• Added a dedicated non-UIAccess GPU worker for isolated NVIDIA telemetry, GPU overclocking and application management, preventing the UIAccess main executable from blocking hybrid-GPU removal.
• Discrete-GPU status now distinguishes an absent adapter (None) from a powered-off adapter (Off). Added a Restart discrete GPU action for Hybrid, Hybrid iGPU and Hybrid Auto modes.
• GPU capabilities recover when the adapter returns; NVAPI power capability probing is deferred until an active NVIDIA discrete GPU is available.
• NVAPI power preferences and independent per-mode locks survive temporary dGPU disappearance and are reapplied after recovery.

Logging and compatibility

• Added INFO, WARN, ERROR and None log-level settings; the default records errors only.
• Improved GPU-worker restart, named-pipe handshakes and resource cleanup after adapter changes and explicit GPU restarts.
• Excluded the 智询常伴 service entry from warranty-date extraction and upgraded the warranty cache schema to version 4.

Release packaging

• Public release packages include the isolated GPU worker. The main executable, GPU worker, Guardian and installer are signed with the project's self-signed certificate.
• The release script now stops if proprietary Lenovo Vantage/Lenovo PC Manager DLLs are present in a public package.

Downloads

• ThinkBookToolkit-1.0.4-Setup.exe (recommended): online installer with a selectable destination. Downloads the official Microsoft x64 .NET 9 Desktop Runtime when required and registers Guardian and the project's self-signed UIAccess certificate.
• ThinkBookToolkit-1.0.4-win-x64-framework-dependent.zip: portable package; requires the x64 .NET 9 Desktop Runtime. It does not automatically register services or trust certificates.
• SHA256SUMS-v1.0.4.txt: SHA-256 checksums for the release assets.

Exit Toolkit normally before installation so it can restore firmware automatic fan control. Restarting the discrete GPU requires administrator permission and may briefly interrupt display output or hardware monitoring.

This version uses a project self-signed certificate, which does not imply commercial CA trust or SmartScreen reputation.

Highlights

Background media and hardware acceleration

• Added image, GIF and video backgrounds with size modes, scaling, transparency, blur, base color and playback speed. GIF playback follows embedded delays, and animated-media previews show the first frame.
• Added disabled, automatic, integrated-GPU and discrete-GPU acceleration options according to available adapters. Changes require a restart; using the discrete GPU in hybrid mode may prevent it from being disconnected.
• Fixed background occlusion, theme colors, GIF composition, video white frames, blur and previews.

Sensor OSD and readings

• Added horizontal/vertical layouts, independent refresh, font size, opacity, position locking, edge snapping and multi-monitor dragging, with General, Colors, Thresholds and Sensors settings.
• Added FPS, 1% Low and frame-interval readings, with configured-game fallback when foreground readings are unavailable. GPU and VRAM are separate groups, alongside RAM, committed memory, device temperatures, battery capacity/power and fan readings.
• Added P-core/E-core average frequencies and battery capacity (Wh) to Overview, OSD and recording. Battery power recording is disabled by default.
• Fixed OSD lock/unlock behavior, multi-monitor placement, clipped options, VRAM utilization and hybrid-core classification.

Sensor recording and history

• Added configurable sampling intervals and sensor selection, minute-batched file writes and automatic .jsonl.gz compression when recording ends.
• History supports time ranges, averaged sampling, clickable legends and hover values. Shutdown finalizes and compresses the current file; when recording remains enabled, the next launch starts a new file.
• Records within the plot-point limit retain their original samples. Larger records are averaged; empty buckets between valid adjacent readings are interpolated without bridging genuinely missing readings.
• Compressed recordings are extracted once for viewing. Temporary files and chart caches are released when switching files or closing the viewer.

Software integration and automation

• Added a dedicated Sensors and integration page. OSD, position locking and sensor recording can be controlled by automation.
• Expanded the loopback HTTP API with optional performance-mode, fan-strategy and full-fan-speed controls. Control access is disabled by default.
• Game start/stop automation detection is independent of the fixed-RPM automatic-game-detection option.

Compatibility and startup

• Added “Automatically enable overclocking when Toolkit starts again,” disabled by default, without deleting saved overclock values.
• Warranty summaries use baseinfo; details show valid detailinfo entries only.
• Improved legacy LITSSVC performance-mode switching and deferred confirmation/retry behavior for Hybrid iGPU switching.
• Fixed settings, locks and Beta conversions when more power values are readable than writable.
• Fixed device-page asynchronous work accessing a disposed cancellation source after navigation.
• Fixed startup and installer launch elevation handling. Guardian now uses a dedicated non-UIAccess service executable to resolve the service elevation error.

Performance and resource usage

• Reduced repeated Overview configuration copying and unchanged property notifications, cached core classification and shared recent sensor samples. Dynamic battery readings refresh quickly while static information is cached.
• Removed the legacy layout and curve editors from the background fan runtime, and release departed pages, closed charts and unused media resources. Actual memory use depends on hardware, media resolution and enabled features.

Downloads

• ThinkBookToolkit-1.0.3-Setup.exe (recommended): online installer with a selectable destination. Downloads the official Microsoft x64 .NET 9 Desktop Runtime when required and registers Guardian and the project's self-signed UIAccess certificate.
• ThinkBookToolkit-1.0.3-win-x64-framework-dependent.zip: portable package; requires the x64 .NET 9 Desktop Runtime. It does not automatically register services or trust certificates.
• SHA256SUMS-v1.0.3.txt: SHA-256 checksums for the release assets.

Install the new Setup package over the existing installation to update the Guardian service executable path. Exit Toolkit normally before installation so it can restore firmware automatic fan control.

This version uses a project self-signed certificate, which does not imply commercial CA trust or SmartScreen reputation. Full-screen OSD support depends on the installation location, Windows, the game and its display mode. Video output is capped at a 1280-pixel long edge, with up to 30 FPS normally or 15 FPS when blurred.

Public packages do not include proprietary DLLs from Lenovo Vantage or Lenovo PC Manager. NVAPI, Intel MMIO and AMD ZenStates power controls remain Beta features. ThinkBook Toolkit is independently developed, is not an official Lenovo application, and hardware control carries risks.

主要更新

NVAPI GPU 功耗调整（Beta）

• 新增可选的 NVAPI GPU 功耗调整，通过固定版本的 LLT NvAPIWrapper 读取并一次写入四项 NVPCF 功耗值。
• 可调整 ATPP（整机功耗）、默认 GPU TGP、最小 GPU TGP、最大 GPU TGP，以及受支持的 Dynamic Boost 和 GPU 温度墙。
• 使用毫瓦接口完成换算；GPU 功耗滑动范围来自 NVIDIA 默认与最大功耗限制。
• NVAPI 与联想 WMI 的 GPU 锁定配置分开保存，并按性能模式独立应用。
• 关闭此功能时直接调用 NvAPIWrapper 的 ResetAll，不再重启 nvpcf。

CPU 功耗墙调整（Beta）

• Intel CPU 可选用 PawnIO 和 InpOutx64 MMIO 路径直接调整 PL1、PL2 与 Turbo Time；CPU 温度墙仍使用 WMI。
• AMD CPU 可选用独立的 GPL Helper 调用 ZenStates-Core，调整 PPT/TDC/EDC 或 STAPM/Fast/Slow 与 TctlMax。
• AMD 功耗显示与编辑统一按照“功耗墙/电流墙在前，温度墙在后”的顺序排列。
• 对应接口只要能够读取数值，就会在完整功能检测中显示为可用，不依赖原有联想功耗接口。

本机数据共享

• 设置中新增“向其他软件共享数据”，默认关闭，默认端口为 2975。
• 开启后可通过 http://127.0.0.1:2975/ 获取 JSON 数据，包括 CPU/GPU 温度与功耗、风扇转速和当前性能模式。
• 数据直接来自最近一次全局刷新，不会增加硬件读取频率；无法读取的字段返回 JSON null。
• 服务仅监听本机回环地址，不对局域网或互联网开放。

兼容性与界面

• 旧机型 GPU 模式切换会根据设备选择旧三模式、G-Sync 或高级 BIOS 路径，同时继续显示“混合 / 混合核显 / 混合自动”。
• 忽略旧机型上不影响实际切换的 GetGsyncStatus 错误，并修复新机型 GPU 模式切换与待重启状态判断回归。
• 旧版 ITS 增加通过 LITSSVC 切换极客模式的兼容路径。
• 概览中的默认、最小、最大 GPU TGP 各自独占一行；Fn 快捷键接管开关与相邻按钮对齐。
• 修复 NVAPI 开关无法关闭、锁定配置无效、页面闪烁和状态提示不消失等问题。

下载

• ThinkBookToolkit-1.0.2-Setup.exe（推荐）：在线安装程序，可选择安装位置；检测不到 x64 .NET 9 Desktop Runtime 时会下载微软官方运行时，并注册风扇安全守护服务。

Highlights

NVAPI GPU power control (Beta)

• Added optional NVAPI GPU power control through the pinned LLT NvAPIWrapper dependency, including a single four-value NVPCF write operation.
• Exposes AC Target TPP, default/minimum/maximum GPU TGP, and supported Dynamic Boost and GPU thermal-limit controls.
• Uses the milliwatt API and derives GPU slider bounds from NVIDIA's default and maximum power limits.
• NVAPI and Lenovo-WMI GPU lock profiles are stored separately and applied independently for each performance mode.
• Disabling the option now calls NvAPIWrapper ResetAll directly instead of restarting nvpcf.

CPU power limits (Beta)

• Intel CPUs can optionally adjust PL1, PL2 and Turbo Time directly through the PawnIO/InpOutx64 MMIO path; the CPU thermal limit remains on WMI.
• AMD CPUs can use an isolated GPL helper with ZenStates-Core for PPT/TDC/EDC or STAPM/Fast/Slow and TctlMax.
• AMD readouts and editors consistently place power/current limits before the thermal limit.
• These capabilities are detected from readable CPU values independently of Lenovo's original power-setting interface.

Local data sharing

• Added “Share data with other software,” disabled by default on port 2975.
• When enabled, http://127.0.0.1:2975/ returns JSON containing CPU/GPU temperature and power, fan RPM and the current performance mode.
• Responses reuse the latest global-refresh snapshot and do not add hardware polling. Unavailable values are JSON null.
• The server listens only on the loopback address and is not exposed to the LAN or Internet.

Compatibility and UI

• Older models now select the appropriate legacy three-mode, G-Sync or advanced-BIOS GPU control protocol while retaining the Hybrid, Hybrid iGPU and Hybrid Auto names.
• Harmless GetGsyncStatus failures no longer block legacy switching, and newer-model switching/restart-state regressions are fixed.
• Legacy ITS systems gain a LITSSVC compatibility path for Geek mode.
• Default, minimum and maximum GPU TGP use separate Overview rows, and the Fn-key takeover switch is aligned with its adjacent actions.
• Fixed NVAPI toggles that could not be disabled, invalid lock configurations, page flashes and persistent status messages.

Downloads

• ThinkBookToolkit-1.0.2-Setup.exe (recommended): online installer with a selectable destination. It downloads the official Microsoft x64 .NET 9 Desktop Runtime when required and registers the fan-safety guardian service.
• ThinkBookToolkit-1.0.2-win-x64-framework-dependent.zip: portable package; the x64 .NET 9 Desktop Runtime must already be installed, and the guardian service is not registered automatically.
• SHA256SUMS-v1.0.2.txt: SHA-256 checksums for the release assets.

Public packages do not include proprietary DLLs from Lenovo Vantage or Lenovo PC Manager. Features requiring those DLLs need legally obtained copies supplied through a supported location or the custom Lenovo DLL directory. The installer and application are currently unsigned, so Windows may display a SmartScreen warning.

Intel MMIO and AMD ZenStates power control are Beta features that require PawnIO/InpOut driver support and may be blocked by Windows security policy. Enable them only if you understand hardware power limits and the associated risks.

The application version is 1.0.2, the replaceable fan-backend API is 1.1, and the configuration-file format is 1.0.

Highlights

Warranty information

• Switched to the Lenovo China warranty endpoint and now uses the latest end date among all valid entitlements for the warranty summary.
• Device information and Overview show the remaining warranty days.
• Added a detailed warranty window containing normalized entries with valid start and end dates.
• Upgraded the local cache to a versioned format that includes entitlement details; old cache data is refreshed automatically.

Single-fan model support

• Added an explicit single-fan model list, currently containing ThinkBook 16 G8+ IPH.
• Its WMI fan backend uses only 0x04030001 and no longer probes, reads, or writes a nonexistent second fan.
• Overview, live status, tray text, RPM limits, fixed RPM, ordinary curves, and advanced curves now adapt to one fan.

Dark theme and Fn+F10

• Fixed Follow-system dark mode leaving selectors, text fields, buttons, child windows, or native title bars in the light theme.
• The hidden fan runtime no longer overwrites the visible shell's application-wide theme resources.
• Fn+F10 consistently opens Windows screen snipping in foreground and background, without taking an immediate full-screen capture or showing a Toolkit OSD.
• Standard-keyboard, Lenovo WMI, and EnergyDrv screenshot events now share Fn+F10 discovery and custom bindings. Mirrored reports are deduplicated without suppressing double-press actions.

Downloads

• ThinkBookToolkit-1.0.1-Setup.exe (recommended): online installer with a selectable destination. It downloads the official Microsoft x64 .NET 9 Desktop Runtime when required and registers the fan-safety guardian service.
• ThinkBookToolkit-1.0.1-win-x64-framework-dependent.zip: portable package; the x64 .NET 9 Desktop Runtime must already be installed, and the guardian service is not registered automatically.
• SHA256SUMS-v1.0.1.txt: SHA-256 checksums for the release assets.

Public packages do not include proprietary DLLs from Lenovo Vantage or Lenovo PC Manager. Features requiring those DLLs need legally obtained copies supplied through a supported location or the custom Lenovo DLL directory. The installer and application are currently unsigned, so Windows may display a SmartScreen warning.

The application version is 1.0.1, the replaceable fan-backend API is 1.1, and the configuration-file format is 1.0.

Highlights

Automation, macros, and Fn keys

• Added ordered automations covering performance, GPU, cooling, battery, display, sound, input, applications, delays, and macros.
• Automations support manual runs, AC connect/disconnect and game start/stop triggers, plus Fn-key single- and double-press bindings.
• Added keyboard macro recording, per-event key/Down-Up/delay editing, ordinary-key bindings, automation-step integration, and safe release of held keys.
• Added WMI and EnergyDrv Fn-key discovery. Every raw key can be added to the custom list, with identical codes kept separate by source.
• Automation and macro names are unique, while old duplicate names are migrated with numeric suffixes.
• Execution logs include trigger source, queueing, steps/events, elapsed time, cancellation, and failure details. Application paths and arguments are redacted.

Driver updates and firmware tools

• Added a driver-update page that reads Lenovo's public machine-type catalog without Lenovo System Update DLLs.
• Added applicability evaluation, version checks, SHA-256 and Lenovo signature verification, and serialized package downloads/installations.
• Added BIOS I/O and virtualization controls gated by the settings actually exposed by the current firmware.

Game detection, display, and GPU

• Game detection now combines Windows GameConfigStore, effective Game Mode, foreground/child processes, and custom include/exclude lists; exclusions win.
• Added Dynamic Refresh Rate discovery, switching, Fn+R cycling, and synchronization after external Windows changes.
• Every discrete-GPU overclock parameter can be enabled independently. Core and memory clock ranges are supported, and disabled parameters are left untouched.
• Improved dGPU removal, reconnection, and telemetry-resource release so monitoring does not keep Hybrid Auto/Hybrid iGPU adapters connected.

Compatibility, performance, and interface

• Added a bilingual per-version typed risk acknowledgement before hardware initialization and fan-backend notices.
• Significantly reduced startup and feature-detection time. Storage and dGPU telemetry load in the background, with per-feature completion and timing logs.
• Fn actions now refresh controls in place instead of rebuilding pages; rapid presses and double-press detection no longer block the driver event queue.
• Native full fan speed is detected separately from ordinary fan control, with a configurable maximum-RPM fallback.
• Older ITS systems automatically use LITSSVC commands 135/146/148, while modern systems continue to prefer LenovoProcessManagement.
• Fixed fan curves freezing when GPU temperature is unavailable, external refresh-rate changes not updating the UI, gaps in partial power displays, and legacy Delay steps being mistaken for Macro steps.

All features were tested only on ThinkBook 16p G6 IAX with BIOS R2CN57WW and are not guaranteed to work on other devices or BIOS versions.

Changes

Discrete GPU management

• Added dGPU release coordination for Hybrid Auto and Hybrid iGPU modes. Toolkit stops NVIDIA monitoring before firmware removes the adapter and notifies the user after a confirmed disconnect or reconnect.
• Added dGPU activity and NVIDIA P-State reporting to Overview and Performance.
• Added views for applications using the dGPU and an optional action to close them.
• Added NVIDIA GPU overclock controls for core and memory offsets and an optional core-clock range, with reset support. Do not use this feature together with another overclocking application.
• Upgraded LibreHardwareMonitorLib to 0.9.7-pre717 and moved NVIDIA telemetry and control further into the isolated GPU worker so sensor polling does not block dGPU removal.

Fn keys and display

• Added optional Lenovo Hotkeys disablement and ThinkBook Fn-key takeover with a topmost OSD. Lenovo Hotkeys is restored when Toolkit exits or Windows shuts down.
• Fn+Q now supports a configurable performance-mode order and per-mode enable switches; Geek mode is skipped on battery power.
• Fn+R can switch laptop-panel refresh rates. The Display page can select the current rate and configure the rates included in the cycle; 60 Hz and the highest available rate are enabled by default.
• Fixed missed rapid key presses, OSD latency, mute and microphone LED synchronization, Fn+R handling, and unsupported audio COM interfaces.

Performance, cooling, and startup

• Performance-mode and fan-strategy linkage now waits two seconds after a confirmed mode switch before applying the fan strategy.
• Power-limit locks retain independent values for each performance mode.
• Toolkit restores the previously selected fan strategy after a normal restart. The current performance mode is recorded only during Windows shutdown and restored after the next automatic startup.
• Refined the fan-curve editor and replaced the inverted dual-fan synchronization wording with a direct independent-fan control option.
• Windows startup now supports Off, On, and Delayed start modes.

Interface and updates

• Added a short fade-and-slide transition between pages.
• Added the current application version to the native title bar and Settings.
• Settings can check the latest stable GitHub Release. When an update is available, the version row shows the latest version and a Download update button.
• Added feature-monitoring entries for GPU management, overclocking, refresh-rate control, Fn-key takeover, and software updates.
• Removed the unavailable PCH temperature item and its unused hardware module.

Downloads

• ThinkBookToolkit-0.2.7-Setup.exe (recommended): online installer with a selectable destination. It downloads the official Microsoft x64 .NET 9 Desktop Runtime when required and registers the fan-safety guardian service.

本次更新

风扇安全与稳定性

• 修复覆盖安装时 Toolkit 驻留托盘导致安装器无法关闭程序的问题。新版安装器会先请求 Toolkit 恢复固件自动风扇控制并正常退出，再停止守护服务；面对不支持安全退出请求的旧版 Toolkit 时，会明确引导用户从托盘菜单退出后重试。
• 新增按需启动的 Windows 守护服务。主程序被任务管理器强制结束或异常消失后，守护服务会尝试恢复固件自动风扇控制，随后自行停止。
• 订阅 Windows 会话结束事件；关机或注销时先停止后台风扇写入并恢复固件自动，避免最后一次转速写入被长期保留。
• GPU 遥测移动到独立子进程。独显驱动或原生监控接口在设备断开、禁用或卸载期间发生异常时，不再直接终止 Toolkit 主进程，并会在独显不可用时尝试显示核显读数。

概览与散热界面

• 新增“简洁模式”和“详细模式”两种概览布局，并可分别编辑当前模式显示的卡片与数据项。
• 简洁概览新增内存与保修信息卡片；在保设备可显示剩余保修天数。
• “实时状态”移动到“散热”页顶部，增加“显存与热点”读数，并从“性能”页移除。
• 修正风扇目标格式、保修剩余天数显示和部分功耗接口下的空白卡位。
• 更新透明四角的软件图标，并将相关机型名称统一为 ThinkBook 14 G6+ IMH。

性能模式与风扇联动

• 增加“切换性能模式时自动切换风扇策略”，可为省电、智能、性能和极客模式分别选择固件自动、固定转速、五个风扇曲线 Profile 或高级曲线。
• 增加“使用风扇控制时切换性能模式”，并提供无需切换的模式白名单。两种联动方向可独立配置，单独切换风扇策略不会反向改变性能模式，除非显式启用第二项联动。

已知限制

• 本版本隔离了独显卸载时的崩溃风险并支持事后回退到核显读数，但尚未在联想“混合自动模式”准备断开独显之前主动释放所有 NVIDIA 监控资源；部分设备上 Toolkit 仍可能阻止离电后的独显自动断开。
• 守护服务由安装程序注册。便携版不会自动安装该服务，因此主程序被强制结束后的风扇自动恢复保护仅在已正确安装服务时可用。

下载

• ThinkBookToolkit-0.2.6-Setup.exe（推荐）：在线安装程序，可选择安装位置；检测不到 x64 .NET 9 Desktop Runtime 时，会下载微软官方运行时安装包，并注册风扇安全守护服务。

All features were tested only on ThinkBook 16p G6 IAX with BIOS R2CN57WW and are not guaranteed to work on other devices or BIOS versions.

Changes

Fan safety and reliability

• Fixed overwrite installation while Toolkit is running in the system tray. Setup now asks Toolkit to restore firmware automatic fan control and exit normally before stopping the guardian service; when upgrading an older Toolkit that does not support the safe-exit request, Setup provides a focused prompt to exit from the tray and retry.
• Added a demand-start Windows guardian service. If the main process is forcibly terminated or disappears unexpectedly, the service attempts to restore firmware automatic fan control and then stops itself.
• Added Windows session-ending handling. Shutdown and sign-out now stop background fan writes and restore firmware automatic control before the process exits.
• Moved GPU telemetry into an isolated child process. Native driver or monitoring failures during discrete-GPU removal, disablement, or unloading no longer terminate the Toolkit process directly, and integrated-GPU readings are selected while the discrete adapter is unavailable.

Overview and Cooling interface

• Added Compact and Detailed Overview modes with editable cards and readings for the selected mode.
• Added compact memory and warranty cards, including remaining warranty days for covered devices.
• Moved Live status to the top of Cooling, added combined VRAM and hot-spot temperatures, and removed Live status from Performance.
• Fixed fan-target formatting, warranty remaining-day visibility, and empty slots when only part of the power interface is readable.
• Updated the application icon with transparent corners and standardized the model name as ThinkBook 14 G6+ IMH.

Performance-mode and fan linkage

• Added automatic fan-strategy selection for Power saving, Intelligent, Performance, and Geek modes, with firmware automatic, fixed RPM, five named fan-curve profiles, and Advanced curve choices.
• Added an optional performance-mode switch when fan control is used, together with a no-switch whitelist. Both linkage directions can be configured independently.

Known limitations

• This release isolates crashes during discrete-GPU removal and can fall back to integrated-GPU readings afterward, but it does not yet proactively release every NVIDIA monitoring resource before Lenovo Hybrid Auto begins detaching the GPU. Toolkit may still prevent automatic battery-mode detachment on some devices.
• The installer registers the guardian service. The portable package does not install that service automatically, so forced-termination fan recovery is available only when the service has been registered correctly.

Downloads

• ThinkBookToolkit-0.2.6-Setup.exe (recommended): online installer with a selectable destination. It downloads the official Microsoft x64 .NET 9 Desktop Runtime when required and registers the fan-safety guardian service.
• ThinkBookToolkit-0.2.6-win-x64-framework-dependent.zip: portable package; the x64 .NET 9 Desktop Runtime must already be installed, and the guardian service is not registered automatically.
• SHA256SUMS-v0.2.6.txt: SHA-256 checksums for the release assets.

Public packages do not include proprietary DLLs from Lenovo Vantage or Lenovo PC Manager. Features requiring those DLLs need legally obtained copies supplied through a supported location or the custom Lenovo DLL directory.

本次更新

概览与硬件监控

• 概览页增加可自定义的监控卡片与数据项，并新增功耗限制、保修信息卡片。
• 扩展 CPU、GPU、内存、硬盘、电池和风扇读数；受支持时可显示逐颗显存温度。
• “性能”页的实时状态与概览页使用相同的显示项目设置。

功耗与设备支持

• 为 ThinkBook 16p G5 IRX 和 ThinkBook 14 Gen 6 Plus 增加对应的功耗设置支持；其他具备 WMI 功耗接口的设备可以显示实际可读取的项目。
• 功耗锁定现在按性能模式分别保存，切换回某个模式时会恢复该模式锁定的目标值。
• ThinkBook 16p G6 IAX 的 GPU Power Boost 滑动条范围保持 0–15，手动输入允许任意非负整数。

界面与稳定性

• 将“性能”和“散热”拆分为独立页面，风扇控制移动到“散热”。
• 优化响应式布局、概览功耗显示、设置项排列、深色原生标题栏以及“启动与程序行为”区域。
• 增加运行日志、硬件读数强制刷新和单实例启动处理。
• 增加显示适配器在线检测并刷新 NVIDIA 私有监控句柄，降低独显被禁用或卸载后访问失效设备造成闪退的风险。

• SHA256SUMS-v0.2.4.txt：发布文件的 SHA-256 校验值。

公开发布包不包含 Lenovo Vantage 或联想电脑管家的专有 DLL。依赖这些 DLL 的功能需要用户在合法拥有相应文件的前提下，通过 Toolkit 支持的位置或“自定义联想 DLL 目录”提供。安装程序与主程序当前均未进行数字签名，Windows 可能显示 SmartScreen 提示。

本版本的软件版本为 0.2.4，可替换风扇后端 API 版本为 1.1，配置文件格式版本仍为 1.0。

The authors and contributors are not liable for hardware damage, data loss, system instability, or any other direct or indirect loss.

Changes

Power-settings layout

• Moved every per-parameter power lock switch to the far right of its setting row, after the slider, input, or selector.
• Aligned the lock switches and spacing consistently across all power-setting rows for easier scanning.
• This release changes only the switch layout. Per-parameter lock behavior, saved targets, and the shared check interval are unchanged.

Downloads

• ThinkBookToolkit-0.2.4-Setup.exe (recommended): online installer with a selectable destination. It downloads the official Microsoft x64 .NET 9 Desktop Runtime installer when the runtime is missing.
• ThinkBookToolkit-0.2.4-win-x64-framework-dependent.zip: portable package; the x64 .NET 9 Desktop Runtime must already be installed.
• SHA256SUMS-v0.2.4.txt: SHA-256 checksums for the release assets.

Public packages do not include proprietary DLLs from Lenovo Vantage or Lenovo PC Manager. Features requiring those DLLs need legally obtained copies supplied through a supported location or the custom Lenovo DLL directory. The installer and application are currently unsigned, so Windows may display a SmartScreen warning.

The application version is 0.2.4, the replaceable fan-backend API is 1.1, and the configuration-file format remains 1.0.
