Default Re: HP 150 Touchscreen II repair

I did notice when fiddling around that it's possible to fit the co-pro board in such a way that it looks as though it's attached, but it's not in fact fully seated. This may explain why it appeared to work earlier, but not if I attach it firmly into the socket (the machine hangs with all diag LEDs lit). Could it be that this chap has had an upgrade fitted for all these years that never actually did anything?! wow..
