I have a HP Pavilion dv7-1005TX running Windows 7 that's around 3 years old now.
For the last year or so, the power socket seemed to be a little loose - when I plugged the power adapter in, I would usually have to jiggle it for a second before the light would come on and it would charge. However, once it was in, it would stay continuously connected even if I moved the laptop or cord around.
Recently it started taking a bit more jiggling to get it to charge, then suddenly, it just stopped recognising the power adapter altogether. No matter how much I moved it around in the socket, it wouldn't charge at all. Now that the battery has drained, I can't even get the thing to power on.
Things I've tried:
- Opening up the laptop and replacing the DC-in jack. I immediately thought this was the problem as it seemed like the jack was loose, but it didn't solve the problem. I even tried replacing it twice with two different jacks on the off chance I'd botched it the first time.
- Using a different AC adapter
- Pulling the battery out and trying to power it on directly from the AC
- Doing a hard reset
...all to no avail.
Does anyone have any idea what the problem could be? Short of cutting my losses and salvaging the hard drives I have no idea what to do.
Just to clarify, when I hit the power button everything lights up and the computer starts whirring for half a second, then it goes dead again, as though it's not plugged in. The AC light does not come on when I plug it in.
Thanks in advance!!
