Battery draining on new laptop when turned off

[Cimbom]

Bought this laptop last december. It drains around 2% each night even when it is turned off. Is this normal? Because when I leave it off for 14 days, I can see around 15% drainage. I checked the BIOS, but the BIOS is very limited so can't see anything regarding USB activity when turned off. Tried charging my phone while it's off, but didn't get any power so I assume USB charging while turned off is not active. Any tips?

The answer is YES -- it's normal for the laptop battery to drain even while it is shut off.

New laptops come with a form of hibernation, known as Fast Startup, enabled -- and that causes battery drain.

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.

@WAWood Forgot to say that fast startup has been off since day 1
