Battery drains while Laptop completely Shutdown

[PRAVZ]

Hi Fozman1,

My Battery Overnight-draining issue remains unresolved even after updating my laptop's BIOS to F.40 dated 09.11.2020 😞  . I just started my laptop post 24 hrs of complete shutdown, the battery levels became 89% :(( . That's what I asked you and all experts here that: Should I update all the remaining drivers showing on my above HP-UPDATES LINK, which you sent?? Will that help for my laptop's battery issue??

Hi,

I'd certainly install all of the updates. Whether that will solve your battey issue, I don't know... I'm not a techie expert (I know enough to be dangerous 😂) but I do know that updating the BIOS solved my battery drain problem which is why I suggested that you tried it

Cheers

Hello @PRAVZ 

Compared to computers 20 years ago , todays computers (computers nowadays) do not completely shut down.

A complete shutdown would be your PC turned off with battery completely removed from your device. Most computers have battery inside the PC, though, so removing it is not so easy to be done on a daily bases.

• Computers use >UEFI<  (not a BIOS) and
  some have Modern stand-by

• Your PC may have also an option to charge other devices via USB, this takes power
• There is >Intel ME< 
• There may be options for WakeOnLAN, etc.
• Windows 8 and 10 do not completely turn off your PC by default. They use "Fast start up" option which is sort of hibernation >> https://www.howtogeek.com/243901/the-pros-and-cons-of-windows-10s-fast-startup-mode/

• Your battery may be old or may need replacement.

You should definitely update your drivers - use >HP Support Assistant< , use Windows Update.

Go to BIOS/UEFI (F10) and review for any options that might consume extra power such as the ones mentioned above.

To conclude , 10-12% discharge for 24 hours is not way too much in general. Nothing to worry about
