I’m having a nightmare with a HP G62 – 105SA laptop that will only run on battery.
With the AC adaptor and a drained battery attached, the power socket LED lights up white, then flicks to amber to show that it’s charging the battery. Which does indeed charge.
Once the battery has some juice in it I can power on the laptop and Windows loads. Once I’m at the desktop however, the power indicator in Windows shows that it is only running on battery and is not plugged in. The battery then drains and I have to power off so that it can charge.
If the battery has drained or if it is removed and the AC adaptor is plugged in, the power socket LED still indicates that the AC adaptor is attached but when I press the power button nothing happens. No power LED, no fan, nothing.
I’ve tried doing a hard reset by removing all power and holding down the power button for a long period of time (over 2 minutes) but it didn’t help. I’ve also tried an alternative AC adaptor but it still behaves the same.
Checking through HP’s FAQs and Knowledge Base hasn’t been of any help either, although the HP forums have a few users with similar issues but no conclusive advice on how to resolve them.
Any ideas anyone?
