Unplug Charger, Laptop Dies

[Whoops01]

My laptop dies as soon as I unplug the charger. Initially I thought it was a battery issue, I have replaced the battery twice but the same issue still exists. My battery is full charge, even if I unplug the charger (after it dies) I can easily turn on the laptop with only the battery and it shows full charge plus I get 4-5 hrs of backup.

The issue is when I unplug the charger or when the power goes. I am not sure if there is any issue with sudden voltage change.

When I bought the laptop years ago, within 3-4 months my power adapter conked off. I bought a new original power adapter (I did not had the invoice for the replacement as I was away from my native city). The laptop never gave me any issues earlier but this has started since the last 3 months.

I also installed a new windows but it has been over 6 months, I am not sure if it is a software issue. Your help is needed.

I also tried the Hardware test by pressing F2 but I do not get the hardware option in C125

Voilla, the issue got fixed.

Thanks so much for all your help.

What was the problem, can you please explain?

Hi, it did worked for an hour or so, but when I unplugged after an hour, the laptop again shutdown as soon as I removed the charger.

Please suggest what might be the issue. Do you feel I should buy a new adapter or there might be some other issue.

Thanks
