I got a tedious problem with the battery of my 8 month new HP ProBook laptop not charging and this since ±4 months.

The pc is mainly on grid current but the battery charging monitor showed  always something like for example 95% or 97%  and also always 'Battery not charging' instead of 100% fully charged as it should be.

The battery test said: Primary battery OK

I suspected a software problem

Removing the Microsoft ACPI battery driver via Control Panel did not help after reboot, same problem.

There had been some BIOS updates, I knew and I searched for a method to go back to the original BIOS

So I tried out: HP Notebook PCs - Restoring the BIOS

First I had unplugged the power adapter for 1/2 hour to discharge the battery to ±85% level.

The restore program asked at certain point also for allowing 'Unrestricted BIOS rollback' which I did.

And suddenly I saw that the battery was charging again and the charging level increased also steadily to 100% fully charged.

The problem was solved apparently.

Probably I got a not perfectly suited BIOS update and that must be at the origin of the not charging problem.

The current System-BIOS version is N78 Ver. 01.15

I made also a backup of the BIOS on a USB flash drive which gave after unzip a ROM file of 16,384 kB

I had already earlier created successfully a web case ticket for the same problem and after following all the instructions the problem was solved but not permanently and the same problem reappeared after a certain time.

Now it's solved permanently I hope.
