HP trouble codes

[Fred Claus]

Client just dropped off an older HP laptop. It won't turn on no noises or anything. When I go to plug it in instantly I see the power lights and the caps lock light blinking one time every couple seconds. A search of the trouble code shows that when the caps lock light blinks once every couple seconds it's a CPU failure. Does the fact that the power light blinking as well cause it to be a different issue or is it safe to say it's the CPU?

Either motherboard or CPU sadly.

In every case I've encountered this its always turned out to be motherboard failure. Quickest remedy is to just remove the HDD/SSD and put it in another laptop.

Model might help some.

I would try a BIOS update first.

To do a BIOS update the machine needs to power up at least to the BIOS screen. There is no POST. The motherboard is dead.

Not true. The blind BIOS update procedure exists for such situations. A blinking Caps lock key is typical symptom of a corrupted BIOS/EC firmware.

Hadn't heard about this one before.
