Battery doesn't charge more than 90%

[Oiddocrop]

Hello,

It is the second time I notice that: when I plug the cable to charge the laptop, it doesn't charge more than 90%, now it's plugged since more than 1 hour. I don't know when it started (probably after some Windows update), I just noticed it today for the second time. 

And sorry for my English, it's not my native language 🙂

Many thanks for your help!

@Oiddocrop Welcome to HP Community!

I understand that Battery doesn't charge more than 90%

Please uninstall the ACPI drivers 

Right-Click on start button> click device manager> Batteries>then select the s drivers and right-click on it and uninstall all battery drivers. 

Then restart the computer and check again.

Also, update the BIOS.

Hello @Praveen196 🙂

So, the  "Test the battery using HP Hardware Diagnostic" does't work. It says it's not working and to contact HP assistance, wow! 

After writing here, I've tried few times to discharge the battery until pc turns out and this solution seemed working: it charget up to 91%, 92% and 93% till today: now it's plugged but only charged till 86%.... EVEN WORSE!!!!

I'll try the suggestions you wrote by first uninstalling the ACPI drivers. I will keep up-to-date 🙂

Bye!

Hey @Praveen196  !

I updated the bios, but I'm not sure where to click for uninstall this drivers so I put a screen shot. I guess it's the third voice of the menu that comes with right click but I want to be 1.000% sure!!!!

Sorry sorry sorry if it is a dumb question (I'm sure it is 😄 )

Yes, you are on the right page. Please uninstall the battery drivers and then try to update the BIOS.

Also, perform the battery calibration.

Hello @Praveen196 !

So now after uninstalling drivers and updating bios it's charging until 99% - the last 1% is missing since a couple months or so and I don't know why 😕

Many thanks!

Hi @Praveen196

I've tried, but still missing the last 1%.

This is normal behaviour on Windows 10 I think. My non-HP devices do the exact same thing. It's the way Windows 10 is handling the battery. Because charging it from anywhere between 60 to 100% fully, making it full will only degrade the battery quicker so if it isn't charging to the max, it'll stop it from wearing out early.
