Product: HP Omen 15-ax201ur
Operating System: Microsoft Windows 10 (64-bit)
Hi. I have an HP Omen 15-ax201ur laptop. When it is turned off, the battery drains in a few days. I have tried turning the laptop off, disconnecting the battery for 15 minutes and reconnecting the battery, the battery has not drained in a few days. So some driver is draining the battery. Any idea what it could be? Thanks

Win10 has 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.
