Battery 100% but still laptop is not turning on when unplugged

Windows 11 task bar icons shows 100% charge. I did confirm this by generating battery report, it too showed 100% charge.

But when I unplug the charge the laptop dies.

The battery was replaced 1 and 1/2 months back. Before that I had a dead battery, I was using laptop plugged. But after replacing the battery it was working fine on battery power. I was getting backup time of about ~3hrs (this is exactly same that I got when I purchased the laptop).

But last day after fully charging the laptop, I unplugged the charger and tried to turn on but it was not able to boot.

So, I plugged in the charger again and tried to boot and it turned on.

At the time of posting this, the battery had a small drain and now it shows 97% charge, the Capacity Remaining section in battery report also shows a small drain.

Batter report still shows my battery details in Installed battery section





Last three day usage





How do I verify whether this is battery issue or a circuit board issue ?

 

Laptop dies without power supply even tho battery says it has charge


My laptop (HP 15 Notebook PC) won't boot unless it is plugged in even though the battery apparently has charge. (It won't charge past 73% also?) If I unplug the power supply it will die instantly. This started happening yesterday after I installed the latest windows 10 update and I just wanted to see if It is software thing before I go and buy a new battery, any help appreciated thanks.

 

Laptop battery issue

Hey everyone! I have an old dell laptop with a pentium 2 and 64MB of ram. Real powerful(lol). It is running 98. The old battery had died and purchased a generic replacement supposedly for that model. The numbers match and all. The problem is the notebook will not recognize the battery. Any suggestions appreciated. Thanks. It is just for notes and stuff.
