Battery charging

[BobRV]

For two years or so my battery charger said 'Fully charged (100%)'.  Then a few weeks ago it said '69% (plugged in, not charging). HP Battery Check confirmed it was down to 69%, but said the battery was OK. I used a trick I learned a few years ago to reset the battery charger.  It is now back to 'Fully charged (100%)'.  So I have two questions -

What's the use of the HP Battery Check?

What caused the battery charging to stop functioning properly?

Hi,


Uninstall HP support assistant software and reinstall this version:

Can you do battery test from HP support assistant software now and tell me the report, what are the cell voltages, cycle count, capacities reported?


Regards

I did install the Support Assistant update, & ran Battery Check. But since I had already reset the batttery charger & charged it back up to 100%, the Battery Check shows 100% & so did the previous version of SA. I have saved screenshots of the Battery Check when it was showing 69% - plugged in, not charging. But I don't know how to attach files to these Posts.

I suspect that the reason for the battery charging to stop working was an automatic update that affected the battery charging but that needed a computer shut down & restart to take effect.  I don't do that very often but after I did that battery charging is back to normal.

Electronics can be very glitchy.

Updates are causing few issues like you're seeing, recently. I've no idea why that should be unless it is BIOS update. Windows updates shouldn't be controlling battery.

Possible Microsoft battery driver issue is the only thing I can suspect, which can be corrected in uninstalling and restarting again.

HP support assistant software is very glitchy piece of application. I usually do not do any updates through that except for battery testing. Still I keep it updated to very recent version.
