Preface:
I had an old HP dv6500 (amd) laptop laying around. It came with Vista but was updated to Windows 7. I wanted to play around with some Linux on it to learn, so I made a bootable drive to install a distro.
The USB would not boot (later it turned out to be a faulty USB drive), so I decided to see if I could find a BIOS update.
HP has removed the support site for this model, so a after long time searching I found the right bios update on HP’s FTP server.
The Disaster:
I ran the update from Windows 7 (I know now, that was a rookie mistake). The update progressed normally, erasing and reprogramming one block at a time. But then as the last block was erased and reprogram the computer turns off, out of the blue.
No windows shutdown, just a click and it was completely off. As if I cut power.
Only the charger light was still on. After 10 seconds I tried to press the power button and nothing happens. No beeps, no fans spinning, nothing. Completely dead!
Repair attempts so far:
Here are the other things i have tried, non of them as worked or changed the pc condition-
I want to take this as a learning experience and try to fix it, but I don’t want to waste too much time going down wrong paths.
Right now by best guess is that the BIOS is faulty.
Can these symptoms be a faulty BIOS?
Charge light on, but not turning on at all with no beep or fan spin.
If it is a BIOS problem, I was thinking to attempt to re-program it with an Arduino or a RaspberryPi. Or replace it if it’s fried.
I have not tried something like this before, but since the pc is old it might be fun to try, even if i break it.
Any help or input is appreciated.

Here are the other things i have tried, non of them as worked or changed the pc condition-
- I have disconnected the CMOS battery hoping for some sort of reset.
- I have measured the voltage of the power source and it’s working fine.
- I have tried to boot without hdd, 1 ram stick, 0 ram sticks
