Sleep wakeup causes CPU low-power lock on ROG Zephyrus G14 Air 2026

[SuperNBplus]

Hello seerge,
I just got the new 2026 ROG Zephyrus G14 Air with RTX 5070 Ti and encountered a rather annoying issue.
After waking from sleep for more than 5 minutes, the CPU gets locked into low-power mode with its P-cores throttled. This is barely noticeable during light office tasks, but performance drops significantly under heavy workloads.
What makes this tricky to troubleshoot is that Task Manager shows normal combined power consumption for both P-cores and E-cores. Tweaking Windows power plans or disabling Fast Startup does not help.
Similarly, adjusting power limits and fan settings in G-Helper has no effect — likely because the EC firmware enforces low-level hardware restrictions that third-party tools cannot bypass.
I’m not sure if this is a Windows 11 scheduler bug or a power management peculiarity specific to Panther Lake.
I’ve found a functional but cumbersome workaround:
Run ThrottleStop as administrator, set PL1 = 55W, PL2 = 75W, enable the corresponding Clamp option, and untick Disable Controls, Sync MMIO and Speed Shift. This forces the CPU out of the low-power state and restores normal performance scheduling.
Could you please look into this EC-level power restriction and optimize G-Helper to fix this problem? Thank you very much for your great work!

@SuperNBplus hello,

It's probably some EC misbehavior due to a broken windows sleep that needs to be fixed with a BIOS update.

• Does changing ANY settings in the app after it happens help to solve the problem ?
• Does it happen if you use all default mode w/o any custom settings (i.e. click Fans + Power -> Factory Defaults) ?

Thanks for the fast response. None of the app settings work, and the issue persists on factory defaults.
Also, after configuring ThrottleStop, the system only goes back to normal after a brief sleep.

@SuperNBplus then it's just bugged firmware that needs to be fixed :)

It’s quite frustrating: After waking up from sleep with default settings, the CPU runs normally at times but gets throttled randomly. I’m not sure if it’s linked to sleep duration or other factors. I’ve submitted a bug report to ASUS and hope it will be addressed. Thanks for your time.

@SuperNBplus does it happen only only on battery or also when plugged in btw ?

I haven't tested this on battery; I only use the laptop while plugged in.
