I have an elitebook 1040 g4 that I got as a failed laptop, I had it working intermittently for a while, then it stopped completely.
When I started looking at the issue, I took the board out, found I had knocked a diode off the board.
I've resoldered the diode, seems to be connected and passes a diode test on the multimeter.
Frustrated, can't find a schematic, not sure what's what.

This may help:
Disconnect the power supply and power the computer with battery power. This resets the Embedded Controller/Keyboard Controller.

I don't know why this is the go to solution for this issue because it doesn't work.
I should have added that I have tried this already.
Not having a go, and appreciate all input on this issue, but there's a ton of YouTube videos that also say this that. Some of my reading on this issue is that I might be missing a power supply. Does anyone know the best test points and what voltages to expect. I have battery voltage, 3.3 and 5 and 1.8 and some lower voltages.
Yes you should have. Saves us time and energy.
