hello everyone,
i seem to have a corrupted bios. this is a Dell Optiplex 780 desktop PC and after the bios update process got interrupted it won't boot.
here's what i'm seeing:
initial status: power cord is plugged in, machine is off
press the turn-on button and:
- sound of a relay clicking
- fan starts running
- power lite goes amber
- diagnostic lites 1 & 3 come on
after about 250ms
- power light goes solid green
- disk activity lite and diagnostic lite 4 come on (manufacturer service manual has no info about code 1-3-4)
- status remains this way (green, DAL, 1, 3, 4) for about 7s, then:
- DAL goes off, then 3 more seconds pass, then
- sound of relay clicking, and
- power light and fan go off, 1, 3, 4 remain on
5s go by, then the whole cycle starts again and repeats, indefinitely, every 15s, until i hold the turn-on button for several seconds, then
- fan and power lite go off, and lites 1, 3, 4 remain on until capacitors run out
i would REALLY appreciate it if someone could help with this.
thanx, mike
