guys to add. could it be possible that my power supply brick is broken even though the light(green) on it is on when i plug it?
Yes, that little green LED is only an indication that it's receiving 115v from the wall outlet.
sir, also the light in the laptop is blinking when i plug the brick. would that mean its charging then? if yes, could it be that the problem is on the laptop it self?
It could be a charging indicator, it could also be a warning that it's not charging properly. All laptops work a little differently. You need to check your owners manual for that answer.
It is indicating your external power supply is ok and your problem is with the laptop itself.sir, also the light in the laptop is blinking when i plug the brick. would that mean its charging then? if yes, could it be that the problem is on the laptop it self?
Do you get any beeps or fan spinning noises, and how often do you get the bios vaio screen loading ?
When you power on can you get into the BIOS BY PRESSING f2, f1 or esc at all ?
