I got this PC Compaq Presario 7170, which had a problem with mouse port. It didn't work. Serial mouse is working.
I replaced both ports and soldered a new ones, but since then my keyboard is also reporting a problem on boot - Keyboard error. But it works. If I press any of the keys with led light (num pad, caps lock or scroll lock) keyboard stops responding. I need to unplug it and plug it back in to make it work again.
Even tough my soldering is terrible, I checked all the leads and everything is connected. I also checked surrounding caps and resistors and they seams fine. At least, what I know to check.
Any idea where I could go next?
