This is all too close in design to my failed HP G62-149wm. HP did not honor their warranty when I discovered it would not boot with my smart phone plugged in. It would also crash 5 to 45 minutes later if the phone was plugged in. After 8+ hours and HP changing the motherboard HP has told me it can't be fixed since they buy the bios.

The machine is now in worse shape than before after they changed the motherboard.

I can't reccomend any HP G62 or models that may contain this defect.
