Battery Won't Charge Fully

ASUS, 1909

Battery icon was sitting at 88% for hours. By pulling and reinserting the power cord the percentage will sometimes move up 1% and now sits at 93%. The battery light is orange.

Checked my BIOS version and it's 2014. This laptop was barely used until this year and the power cord is rarely disconnected.

Thanks

Make sure to install all Windows important updates.

Hopefully one of the above suggestions will help you resolve the battery not charging problem. If battery still doesn't charge, you may need to replace your battery.

Run the battery completely flat (put on a few continuously playing videos, let it run it overnight). Recharge.

Repeat 3 or 4 times.

(Had the same experience with an ASUS. Above solved the problem. Have to admit, I suspect the problem lay in the "indication" of the charge level - I think the battery was fully charged but not indicating such).

Can that damage any hardware? I think I read somewhere it can be a problem but can't find where.

"Checked my BIOS version and it's 2014. This laptop was barely used until this year and the power cord is rarely disconnected."
Batteries deteriorate over time even more when not in use.

I assume a laptop can operate without a battery as long as it remains plugged in and should be shutdown should you need to unplug it?

ASUS ... Battery icon was sitting at 88% for hours...

Asus have a 'ASUS Battery Health Charging' utility. This has three modes, Full capacity, Balanced, and Maximum lifespan. The Balanced mode stops charging at 80%. Even if you don't have this utility, you'll probably find the same options are available in the bios. I have a similar utility for my Dell with a number of charging modes, with the same modes listed in the bios options. Check your bios settings before you start looking for faults...

Balanced Mode(Blue color): Stops charging when power is above 80% and resumes charging when power is below 78%.

In the cmd box,type in:
1.powercfg /energy----and see the report.
Then type in:
2.powercfg /batteryreport----and check it's report.
Might give something useful.
