Hi
I have an HP pavilion dv7 laptop that will not boot.
When plugged with the adaptor the charging light comes on and when I press the power buttton all the small lights turn on but the screen remains black. The fans and everything else seems to go on.
Then the computer just works like mad, calms down for a bit then works like mad. All along with a black screen and lights on. The computer doesn't stop doing this until I pull out the power adapter or with a forced stop.
I gave it in to a repair shop and they said it was the power adapter but they couldn't get the part, hp doesn't make them anymore they said.
I opened the computer up to look at the power adapter and could see there was a cable loose. I soldered it as instructions from the internet told me and it just does the same thing.
I have found the power adapter for my computer on eBay, but before I buy it....
Is there anyway for me to know it's the power adapter?
Sounds weird to me that the whole computer lights up (not screen) and the harddisk is spinning and they say it's the power adapter. I've read a lot about people with similar problems but then its the motherboard that's the problem.
I don't want to spend money on the wrong parts.
Thank you for any help you can give,
Because I need it
