laptop cannot start pressing power button, the power light once
I have a Dell inspiron 1501 and possibly some power purge due to connection with some external usb devices, it no longer can turn on pressing the power button. The battery has died and have been removed for a long time so I depend on the ac plug charger/adapter. When I press the power button, its LED light turns on once and then off and nothing seen on the screen. I open the case and see that the power button is that some kind of mechanical push switch on a small piece of pcb. Is that any way I can turn on the laptop by shorting somewhere?
