room mates hp pavilion dv4 won't turn on

HP dv4 laptop will not start, period. won't boot into bios or anything.

she was watching a video on the net and it shut off, and won't even try to start.

pulled her hd out and hooked it up via my usb adapter and the drive won't show up on my comp either.

any common issues like this with HP's?

sounds like motherboard and hd both...

she shuts down properly every time.

ok so I found a buddy with the same hp laptop.

battery and charger work fine on his laptop.

main board looks fine no singe marks or leaking capacitors that I can see and no singed smells.

since the hard disk is not being detected via your usb adapter it might be a case that the Hard disk is malfunctioning it's better to get some professional help in that case. All you can check by yourself is whether the Hard disk is getting power upon connecting with your usb adapter or not.

it shows power when I plug it in but it behaves strange... it clicks every second in the same rhythm. click..........click..........click..
like the disks start to spin and then stop real hard.

she failed to tell me this happened after the power got shut off at the house. it was plugged in when they turned our power back on.

could that have fried something?

the HD clicks when I plug it into the usb adapter

what was she doing when power failed ?

if she was doing only some light work there is a chance that everything is alright however if the voltage fluctuated strongly then there is a very little chance that it survived frying.

and since the HD clicks when plugged into USB adapter there is a chance that the chip wud have fried near the power point. So it's better if you take it to a professional so they can examine it firsthand.

Thanks
