HP battery at 255%

[iamadrum]

Hey.

I have HP laptop HP Pavilion 15-AB223CL. Recently I was charging it and suddenly the battery icon showed 255%. Yet my laptop won’t turn on unless it’s plugged to charger. When I turn it on it says that “battery isn’t detected”.

I know nothing about computers so I don’t know how to fix this. 😞

Important Update: Expansion of the Battery Safety Recall and Replacement Program for HP Notebook Computers and Mobile Workstations announced in January 2018 – Additional Batteries Affected

HP urges customers to recheck all potentially affected products

In cooperation with various government regulatory agencies HP has announced an expansion of its worldwide voluntary safety recall and replacement program for certain notebook computer and mobile workstation batteries announced in January 2018. The potentially affected batteries may have been shipped with certain HP notebook computers and mobile workstations sold worldwide from December 2015 through April 2018.

The batteries have the potential to overheat, posing a fire and burn hazard to customers.  It is essential that you check or recheck your battery, even if you did so previously and were informed that it was not affected.

HP’s primary concern is for the safety of our customers. Because these batteries pose a fire and burn hazard, it is essential to visit the HP Battery Recall website at www.hp.com/go/batteryprogram2018 as soon as possible and check your battery.

Battery will not charge when system is warm to hot

If the “not charging” issue is (only) apparent when the system is running hot (or near that point), the battery and charge system are likely overheated as well – the charge system will resume operation when the computer cools down.  Short Version:  An overheated battery / computer / charging-system will not charge the battery – this is normal behavior.

Battery seems “stuck” in a particular charge setting         

The battery might be OK and just need calibration (balance / set).

The steps to check / calibrate / replace the battery are included in this document:
