My HP Pavilion dv7-1245dx isn't charging it's battery. It was working one day, then my mother took it away for overuse and kept it for a few weeks, and now when I plug it in and turn it on, it won't charge the battery ("plugged in, not charging")! So when it gets unplugged - and it's port is loose too - it shuts off immediately, highly annoying. And I then bought a new battery for it, but got the same message. OS is Windows 7 Pro 64-bit. Can the problem ever be fixed?

I have the exact same laptop. And the exact same problem. I had both the battery and hard drive replaced twice. The laptop is now dead and its still functioning pieces salvaged to be used somewhere else.

Thanks for the responses guys!

Well, she didn't overcharge it: it was in the back of her closet. However it definitely did sit at 0% for a long time; could it harm it?

I could afford a new charger if the vendor of the battery lets me send it back to him. For further information, before this all happened I was having this issue where the battery would charge normally, but then as I used it it would report high levels for a long time - often 100% the whole time - and then shut off without warning. Annoying but it'd last well through an outlet move so I was content. Could it be the fault of the charger?

Juju: so you never found a solution; you never tried a new charger?

Hmm, there was never any liquid involved.  Should I just buy a charger on eBay and see if it works?

Sorry to hear. But did you try another charger?

Yeah, try out another charger, if it doesn't work, change the battery, if not then it's the internal power supply. Which sucks when you get to that.
