I've almost finished rebuilding an HP dv9702ea. The windows/software part went fine.
However after that I thought I would update the BIOS with the latest as found on HP's website. It appeared to work fine, saw the program saying blocks being successfully erased then written. Then saw the message about it having succeeded and to hard boot the laptop if it hung.
It didn't hang and rebooted. However when it did, it appeared to start up normal but it keeps rebooting before clearing POST.
Unfortunately neither the caps lock or num lock LED's light up which may have shed some light on the issue.
I've tried as HP suggested and unplugging everything, hold the power button for 15 secs, then plugging just the PSU, same story.
Unfortnately the laptop is out of warranty. HP want £17 to extend support, but I have a strong feeling I would just be paying £17 to be told to purchase a new motherboard.
If anyone knows any way of me saving this without purchasing a new motherboard, that would make me very happy indeed!
