have had motherboards become static choked, and all you can do if this is the case is to leave it plugged in to power supply, but turned off, for a day or two. don't know if it works with laptops, but sure works great with "dead" motherboards.

My imedia b2217 will not boot. Is the motherboard dead? Whenever I switch on the computer nothing happens. No lights, no fans, nothing at all. I have replaced the power supply but still nothing


Hi i'm Basti,

How bout the fan for your power supply, is it running? Try to retrace the cables to motherboard and make sure its tight. Change or use another power supply if possible.


Keep me posted. Hope this helps.

Might your switch be non-functioning? Can you check that independently?

Otherwise, sounds to me like you did eveything.

Car will not turn over dead no sound


It seems as if you have had a major electrical short in a main power circuit, for this to happen.I would take it to a auto electrician and have a test carried out.

Compaq Presario 700 Series Laptop wont turn on


Please first make sure that your adaptor is working.
Try to remove the battery and connect your laptop to the adaptor. Swith on. If nothing chages, then there is good chance that you have a motherboard related problem.

The connection to the board should be under the panel with the speakers, at the top of the keyboard. (that's where it is on my cf72) Also check the connection on the touch screen by pulling the front case from around the screen. There are screws hidden under the small rubber bumpers on the lid.
