Win 11 Laptop wont wake up from sleep mode

[bailbondishhhh]

Hello

After a recent Windows update, my laptop will not wake up from sleep mode, forcing me to reboot every time it goes into sleep mode. .  The top red led's flash only briefly, then nothing.

I've reset my power options to default, updated bios and tried a clean boot but the problem persists.

Any help would be much appreciated.

Win10 and Win11 have enabled a new hibernation process known as Fast Startup -- which is enabled BY DEFAULT. This is different from Fast Boot, which is a BIOS/UEFI option.

Fast Startup is supposed to dramatically speed up the booting process, but in some PCs, it actually slows it down or causes it to hang. It's also a new form of hibernation known as hybrid sleep -- and this causes battery drain to maintain the state of the PC while turned off. In some rare cases, it can also cause a laptop to overheat because the processor is still running and still generating heat, as this has been reported when the laptop was turned off and put inside a case.

Disabling Fast Startup might fix booting and shutdown problems.

There are two ways to disable FastStartup in Win10: (1) through the Control Panel, and (2) through an elevated command prompt.

Control Panel - Open Control Panel --> Power Options.
Select "Choose what the power buttons do"
Select "Change settings that are currently unavailable"
At the bottom of the Window, under Shutdown settings, uncheck the box regarding fast startup

Elevated command prompt - run the following command:

REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /V HiberbootEnabled /T REG_dWORD /D 0 /F

In both cases, reboot Windows.

NOW, Fast Startup is disabled.

See if that helps.

Many thanks for your answer, but I already have Fast Start up disabled and the problem still occurs.

See screen capture below.

OK, I see what you have set.  Sometimes, sleep mode just does not work properly and all you can do about that is to go into Control Panel (not Settings) and configure the laptop to Shut Down when you turn it off.
