Long term laptop storage

[SubhashreeB]

I have fully charged my HP Notebook, shut it down, and stored it in a laptop bag on a flat surface. The laptop battery is non-removable. 

I have kept the laptop inside a bag to avoid dust collection. I wouldn't be using my laptop for 3 to 4 months. Would it remain intact when I power it after the storage period?

A problem you're going to have is that Windows 10 does not completely shut down a laptop when you turn it off.  Instead, it goes into a hybrid sleep mode and that drains the battery.  I found that after only a week, my laptop battery was so low the PC would not boot anymore,

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.

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, FastStartup is disabled.

See if that helps.
