Check to see if your laptop supports S3 standby

Start by opening command prompt and running powercfg /a

Fixing the problem

Start by opening command prompt as an administrator:

Run reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0

- DO NOT DO THIS IF powercfg /a SAYS YOUR LAPTOP DOESN'T SUPPORT S3 STANDBY
