HP Recommended
Product: HP ProBook 440 14 inch G9 Notebook PC (678R1AV)
Operating System: Microsoft Windows 10 IOT

Hi all, I am on a HP Probook 440 G9 i7 using Windows 10 Pro 22H2 64 bit. I recently changed my sleep state from S0 (modern standby mode) to S3 sleep state. This is because I really do not like S0 because I need to use Ultimate Performance mode for some of my programs. I used the registry editor to add the PlatformAoAcOverride and everything worked out, but when I switched to S3 I noticed that every time I put my notebook to sleep and I try to turn it on again, the keyboard lights up and all but the screen stays blank. The only way if I want to turn it back on is if I force it to shut down by holding down the button and restarting it again, resulting in me losing all my work. I can only get around this by setting it to never sleep and always on the "do nothing" setting. This wastes my battery and wastes electricity. I have now changed to S0 but want to switch back to S3 without the issue. Can this be fixed? Please help, thanks.
