My laptop battery is not charging above 75%

[Arjit2752]

My laptop battery is not charging above 75% and just shows 27 minutes remaining and it constantly remains at 75% when the adapter is plugged in. I tried to calibrate my battery but it didn't help me.

Sometimes my battery indicator LED turns white even if it is not fully charged It later automatically turns orange, showing charging. I am not able to understand the is happening. When the laptop is turned off and plugged in after some time it shows white light at the battery indicator LED, and as I turn it on, it again turns red and always showing the battery below 75%.

till 70% it charges with good speed and after that, it takes hours to charge till 75%.

Also tried to update bios but it didn't solve any issue and the hp support drivers section constantly shows bios at red(i.e. critical) even after updating. Please help me to solve this problem

How old is the battery? You need to run a battery test to check the status of each of the cells, the number of cycles, etc. If the battery is over 2 years old its very likely you need a new one.

Easiest way is with HP Support Assistant within Windows.

It's been more than 2 years and the battery indicator LED is also not working properly, right now it becomes white at any particular percentage, and then after some time automatically become orange and then white and goes on this process. To charge unplug and plug in the charger again and again.

Please suggest me a solution.

I think I already have. Run the battery diagnostic test and post the results here. Very likely you need to replace the battery but we have to exclude other possible problems which would be worse than just needing a new battery, but are very unlikely.

Bad charging circuit on the motherboard....rare but possible
