Battery only charging to 80%

#Post
1

Unfortunately, a few weeks ago I forgot the laptop was plugged in and pulled it towards me a bit forcefully. Since around then, it's only been charging to 80% max.
It's an HP Probook, about 3 years old. The battery report came back normal. Is it worth replacing the charging port? Thanks.

Check your bios - an update recently limits charging to 80% to maintain battery health (80% limit is a good thing by the way...). My Elitebook does that and can be enabled/disabled within the BIOS

If the charging port or cable was broken/damaged it would either charge or it wouldn't. Any damage would not result in the battery only part charging.

Oh wow! Thanks for that. I did run some updates around the same time. Big relief no money to outlay.

I would double check to see if you can charge up to 80+ to make sure.

Yes, that was the cause. Thanks again.

Don't change the setting except for temporarily, it is to prevent overcharging and resulting in battery swelling

On my new Lenovo laptop, there's a new mode called Conservation Mode, when turned ON, it will limit the charging to 60% no matter how long you leave it on charge
