Battery Issue HP

[Shreyash Singh]

My laptop is 100% charged, detects battery, but does not start without a power cord.
It does not boot on a battery and closes as soon as the cord is removed and it completely shuts down. My battery is detected and is fully charged. Please help if I have to change the battery or some technical problem.
Also, my laptop is under extended warranty and accidental damage.

But my battery is detected and fully charged. When I remove it from my laptop it says no battery connected. Should I replace my battery?

yes replace it or have HP do it since it's still under warranty. HP is the better choice as a replacement non OEM battery you may buy cheap are not up to standard and rarely last long
