An HP Pavilion dv7 laptop will not boot, or even post. It does power on briefly (fans spin up, LEDs come on) when the Power button is pressed, but it does not beep/post or display the bios. Instead it almost immediately turns off again. The person who last used this laptop reported sparks going off when the keyboard was touched.
It does the same thing no matter what I've tried, including:
- long pressing the power button
- using just the battery
- plugging in the the charger and removing the battery
- removing both RAM chips
- removing a CMOS battery
