AC Adapter Light blinks when i plug it into my laptop

[Alain17]

a little bit of background first. i no longer have a battery for my laptop. i can only use it when the adapter is plugged into it.

yesterday i tried turning it on, but it doesnt. this morning i tried turning it on again and it turned on, for a few seconds then it died. after a few frustrating tries, i noticed that the AC adapter light would blink on and off, like it wasnt supplying power to my laptop. and because my laptop no longer has a battery, it dies. i tried to plug the adapter to another socket because i thought it was a grounded socket issue, but the same thing happens.

a friend of mine suggested that it may be the radeon video card that i had got somehow fried or overheated or something, so we tried uninstalling it(yes, there was a time it stayed on long enough for me to log in and uninstall my video card). sometimes it would take 5 seconds for the AC adapter light to blink and die, sometimes it takes 5 minutes or so.

after uninstalling my video card, the same thing still happens. when i turn it on, sometimes it only takes a couple of seconds before it dies. sometimes, even if i dont turn it on, the AC adapter light would go on and off, like there was something disrupting the flow of electricity from my socket to my AC adapter to my laptop that causes the light to blink on and off very fast.

could it be a power supply issue?

Yes, it is the power supply. Please refer to the following documents.

thank you so much for your reply. so an update:

yesterday and today i've been able to use my laptop without any problems. yesterday i used it for about 14 hrs straight. today i've used it for about 2 hrs and counting.

what i'm afraid of is that the symptom could return and there might no going back if it happens again. or that something worse will happen. how do i prevent it from happening again?
