I have a compaq presario f700 that shutdown without warning and now I can not get it to turn on. Nothing happens when I press the power button. I have tried it with and without the batttery and I tried resetting the memory cards. I even tried it with the hard disk removed.
If the battery is in the machine then the chargin light it on so I'm pretty sure it is getting power. I also tried holding down the power button for 30 seconds without the battery and external power but that did not fix it.
Is there anything else I can try?
