PATCH TO STOP POWER/THINKPAD LED FROM "BREATHING" UPON WAKE

INSERT INTO DSDT.DSL UNDER OWAK

BEFORE:

If (LEqual (Arg0, 0x03))
{
\NVSS (0x00)
Store (_SB.PCI0.LPCB.EC.AC._PSR (), \PWRS)

AFTER:

If (LEqual (Arg0, 0x03))
{
\NVSS (0x00)
_SB.PCI0.LPCB.EC.LED (Zero, 0x80)
_SB.PCI0.LPCB.EC.LED (0x0A, 0x80)
Store (_SB.PCI0.LPCB.EC.AC._PSR (), \PWRS)

System_Shutdown_restart fixed

This patch is to fix "restart after shutdown" caused by the xHCI controller. by setting XHC.PMEE = 0 after _PTS processing (Arg0 == 5), we can avoid restart after shutdown.

INSERT INTO DSDT.DSL into method label _PTS

    If (5 == Arg0) { \_SB.PCI0.XHC.PMEE = 0 }

Windows Time Fix

Run following command with Administrator privileges in CMD:

Reg add HKLM\SYSTEM\CurrentControlSet\Control\TimeZoneInformation /v RealTimeIsUniversal /t REG_DWORD /d 1 This will force Windows to treat Hadware Time as UTC Time.
