Not sure that mine is the same problem. Brand new Compaq Presario Windows 7. It works fine but on two occasions wouldn't boot. First time it was on battery only, and from a complete shutdown, so I plugged in to mains, and it started fine. Second time was today from Hibernation and first on battery, then mains. It was only after pressing power button for about the 6th time that it booted and ran fine after that.
I phoned support at E-Buy where I got it and a techie there told me it might(?) be a faulty battery (Windows check reports no probs with it and it's fully charged). I have some instructions to try if it happens again, i.e. taking out battery, starting from AC mains only, having first removed all USB connections etc ...
I'm hoping this isn't a more serious problem. I have a phone no. to contact HP if necessary -- the E-Buy guy told me HP would send me a new battery.
Sounds a bit too simple to me, but does this really happen, I mean with the battery?
Thanks in advance for any help here.
