Trak, you can try reseating(remove and reinsert in case of bad connection) the Ram/memory in your computer to see if that fixes the fault your having. I will post a link on how you access the Ram/memory to enable you to try this. Good luck .

I hope this helped you out, if so let me know by pressing the helpful button.

I'm having the same issue as the original post but it happens after i try and install a new trackpad. The error only happens while the trackpad is plugged in though

Have you tried resetting the BIOS?

@aactech

I have not. I'm not entirely sure how to reset the BIOS from a black screen, or if resetting it would work before putting the trackpad back in

Take out main battery. Discharge power by pressing On/Off button. Open case and unplug the CMOS (they call it "backup battery here). Here's the diagram from the manual.

John hall is right about the track pad wire my track pad comes off easily and is snapped off the wire. I tucked the wire into the laptop and it started touching something I’m guessing metal which caused it to short circuit I think. I just had the get out the wire.
