HP DV9000 - Charger Problem


Novice Member
My HP Pavillion DV9646em has stopped charging. No light comes on when plugged in and I can't turn it on as the battery is empty. I have taken it apart to check but can't see anything wrong.

Possible causes:
  1. Charger
  2. AC jack

I haven't tested the charger yet as I don't know anyone with the same charger as me.

Does anyone know how to fix this?

Check battery validity at site above.

1. Check mains lead and change fuse.
2. If you cant find someone with a similar machine that you can borrow AC Adapter to test your machine then you will have to buy another one.(try HP first)
3. If not working with new AC adapter or borrowed one then it would suggest a motherboard problem.

That power jack looks like it just plugs in.

The service manual for your laptop is on the HP website if you wish to download it.

If you have a multimeter you can check the AC adaptor, measure the voltage at the jack end, check the info sticker on the adaptor to see what the output voltage is, it should be around 18.5 volts DC - 3.5 amp looking at the specs in the manual.
