Re: please help 3452 touchpad error
1) is this a Dell? Logic board number? Post full details.
2) what color is the blinking led?
3) is the power adapter a known good adapter? It is the original and recommended unit for this laptop?
4) any liquid damage?
5) does the battery charge ok? Unit can work from battery only?
