Hello,
I saw another thread in this forum about an HP Pavilion ze4500 that wouldn't turn on, but this case is a little different: previously, this laptop's battery would not hold a charge, so we had to keep in plugged into the charger every time we used it. Recently, however, it has begun holding a charge and lasts on it's own for about 1 hr and a half.
Today, it suddenly turned off, but was charging. Soon the light indicated that it was fully charged, so my sister unplugged the adapter and tried to turn it on. The light flashed for a moment, the hard drive seemed to start (buzzing noise) but then it didn't start. So we plugged in the adapter again, but no light came on to show that the laptop was on AC power...nothing. When we tried to turn it on this time, no response at all. It's completely dead.
We've tested it with many other adapters, same problem. My question is, should we buy a new internal battery? Is it possibly the motherboard that needs replacing? And if so, is there any way to recover the data on there?
Thank you for any help!
