[SOLVED] Dell 4700 will not boot up

Art Astarita · 10-28-2008, 03:26 PM

After hitting the on button, the computer hard disk whrills then stops and the left light on the tower lights amber. this has happened a few times but I've had success after turning power off and waiting a few minutes.
It seems it's in a sleep state but I cannot get it to wake up by keyboard or mouse actions.

I seemed to have got the 4700 running by pulling the mother board battery out overnight. When I put it back in, it booted fine. It seems that the bios was screwed up and needed to be reset. I hear one can also toggle the bios jumper temporarily by putting the battery in between toggles.

normal method
cmos reset
turn the computer off
remove the power lead from the back
take the side off
remove the cmos battery
move the cmos jumper from pins 1 and 2 to pin 2 and 3 and the back to pins 1 and 2
reinsert the battery
put the side on
replug in the power lead
boot the computer

there can be 2 solder points you touch with a screwdriver
2 pins you touch with a screwdriver or use a jumper
a cmos clear switch or button
there will be a diagram and instructions in your manual
