Mac pro efi firmware update 1.5 download8/27/2023 If you already have a dual boot environment, you have to replace your boot manager with reFind being used in this tutorial. Also just for a normal Windows environment with no other boot manager being used other than the normal Windows boot manager. (below is obsolete, dont use anymore). Another workaround is: You need to touch the touch pad at least ONE time, after every S3 wakeup. ![]() This changes everything! If you disable the trackpad in device manager or the Intel IO devices, then S3 works normally on the 9570! No drain after wake up. It is caused by the trackpad and/or Intel IO GPIO drivers. I found out what is the root cause of the runaway issue and power consumption after S3 wake up n the 9570. Reg add HKLM\System\CurrentControlSet\Control\Power /v EnforceDisconnectedStandby /t REG_DWORD /d 1 Will always disable wlan/lan when switching to modern standby: Reg add HKLM\System\CurrentControlSet\Control\Power /v EnableInputSuppression /t REG_DWORD /d 1 Will prevent for example bluetooth mice to wake up the laptop, even with lid closed on battery: You should also do the two following tweaks which will prevent catastrophic drains for 2 major issues with modern standby: Warning: if your laptop is newer than 2019, there is a high chance, your OEM removed any S3 code from the bios, and your laptop will crash entering S3 and you have to force hold power key to restart and then delete the registry entry again to revert back to modern standby. Reg delete "HKLM\System\CurrentControlSet\Control\Power" /v PlatformAoAcOverride You can just run regedit as admin and delete PlatformAoAcOverride under HKLM\System\CurrentControlSet\Control\Power again to revert back. Reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0 Removing the entry again to get back modern standby. You might be able to disable modern standby with this registry flag, so no refind needed, so setting PlatformAoAcOverride to 0 under HKLM\System\CurrentControlSet\Control\Power. Or has just bad drain in general, compared to S3. You CANT revert back to S3 now anymore, and are stuck with bad modern standby, which is a ticking time bomb, can melt your laptop to death or drain your battery in 1-2 hours randomly. Up from Wind(2020 May update), MS also removed the CsEnabled option from registry. That was already a disgusting and incompetent move, however, the worst was yet to come: I was just tired of Dell and also Microsoft, both forcing you into Modern Standby, which never worked, doesnt work, and will not ever work reliable on Windows, compared to 100% working and reliable S3 (suspend to RAM) sleep.ĭell removed, for NO REASON, the bios option on most of their laptops, to force S3 sleep (long gone on 9570 since bios 1.3.0).
