Hello,


Got a HP Pavilion dv5. It is about 5 years old.

Last Tuesday the AC Adapter started to heat more than usual. At first the laptop turned off and I waited for the AC Adapter to cool down and retry it and it worked. After reusing the laptop for another 30 minutes, the AC Adapter went very hot again and a small bang sound went from it (it died).

I got a new universal AC Adapter but the laptop won't start.

Symptoms:
When I plug the new AC Adapter into the power jack, the light near the power jack turns on like it did with the old one, when I press the power button to turn it ON, nothing happens.

My battery is long time dead but I tried it anyway. With battery and AC Adapter the light in front of the laptop (front left) is on, showing that the battery charges but when I press the power button to turn the laptop ON, that light shuts down and nothing happens.


Any ideas? Thank you.

Hello Gabri88,

When you plug the charger into the jack, can you see the light blinking or just everything remains calm and nothing can be heard from the fan or the hard drive?
If you can't and the warranty of your laptop has expired I suggest you to take out the hard drive and try to connect it to another computer through SATA-USB cable. If your hard drive spins up on a different computer and it is recognized there, but cannot power up on your laptop, then the problem is hiding probably in the power supply unit on your motherboard. You could bring your laptop to a technician to make a test of the power connector and/or the power jack center because they might get damaged. If the HDD doesn't spin at all, anywhere, then it has failed mechanically and needs replacement.
Have you checked the compatibility of your AC adapter and the voltage needed by your laptop? The power may be going to your motherboard but might not be enough to make the drive spin up.

Best of luck.
