Solve : HP Laptop shutting down a few minutes after unplugging charger

1.	Solve : HP Laptop shutting down a few minutes after unplugging charger?
Answer» Hello. I have HP Laptop and since a month, it's been having these problems - 1. Despite plugging in the charger 24/7, the battery icon never SHOWS 100% full. It stops between 90-95% available. 2. There's this problem where despite no power fluctuation, or voltage issues, the battery "charging" symbol keeps showing on and off, the battery charging also keeps going on and off, it shows with my screen going dull/bright every few minutes. I've tried charging it in many different places, but it keeps happening everywhere. 3. When I unplug my charger, the laptop has been shutting down after such a less time. Initially, it began with shutting down after 40 minutes of unplugging, and now it's come down to 10-15 minutes. This is despite the battery symbol showing more than 50 % battery. 4. I have stopped getting the "battery is low" notification, which used to appear twice on screen, once around 20% battery and another around 10%. (sorry I forgot exact figures) 5. The glowing button on the left side near the battery pin socket is glowing white (meaning full batter), even though the battery is never full. It's over an year old(maybe 1.5 years old). What's wrong with my laptop? Please help me. Thankyou in advance. sounds like the battery has a failure. I had a laptop years ago where the battery held no charge, unit was just on 2 years old. under warranty still?

Batteries rarely can be reconditioned like this full charge/full discharge cycle after they are troubled, and this and other methods of jarring the cells to come back into it very rarely work from my attempts myself in the past. I have GOTTEN some batteries to slightly come back into it through a full discharge full recharge cycle, but they dont act like new and for example the battery that was troubled that would dive in 5 minutes or less MIGHT work for 20 minutes after reconditioning of cells, but a new battery would last 1.5 hours so the battery clearly is not corrected of its troubles in health. It would likely be a waste of 4 hours.

Hello. I have HP Laptop and since a month, it's been having these problems -

1. Despite plugging in the charger 24/7, the battery icon never SHOWS 100% full. It stops between 90-95% available.
2.

It's over an year old(maybe 1.5 years old).

What's wrong with my laptop? Please help me. Thankyou in advance.
sounds like the battery has a failure.

IDK about warranty, I have to ask my dad.

So, I will have to buy a new battery??

Is there any reason why have I stopped receiving notifications of low battery from my laptop though?
