Laptop stopped working after replacing the battery

I replaced my laptop with a new original battery and it didn't boot first time without charging then I charged it til 93% and it ran for 4-5 hours long after which it was at 32%, that when I decided to charge it again.

As I put in the charger, the light on the charger started blinking and the laptop immediately turned off, the charger blinked for 2-3 sec, then it stopped blinking.

The charger light would go out when I will plug it in the laptop and will come back on as soon as I plug out the charger.

Now the laptop would not turn on with the battery but withour charger or with only the charger.

I took out the battery as soon this happned and tried to hold the power for 30 sec to try again but still it would not turn on.

Should I return the battery as it has still a return window left because I do not know what is broken at this point?

For context, I brought a new battery beacuse my old one lost all capacity after 8 year of use ( it will not keep the laptop on for even a second) , I was running my laptop on just the power adapeter for a month.

Hi @mohdafzal40548

Have you got a DMM (digital multimeter)?

If so then the first thing to try is check that the charger has 19.5V DC on the output plug of the charger.

If the charger isn't supplying the correct voltage anymore, the laptop can't operate or the battery be charged.

I don't have one. But the laptop would not turn on with the battery which was 33% at that time.

I'm concerned by the fact that you said that when you plug in the charger "...charger light would go out when I will plug it in the laptop and will come back on as soon as I plug out the charger."

You need to eliminate it as a possible cause of the problem.

Also just because a battery shows 33% doesn't mean that it can handle the load if it was faulty i.e. fails under load problem perhaps.

Hopefully by a process of elimination you can narrow down what's happening and not just throw parts at it, maybe unnecessarily.
