How do I get into the bios on my Dell Optiplex 760 PC MY

Resolved Question:

How do I get into the bios on my Dell Optiplex 760 PC?

MY PC is a Dell Optiplex 760 (which came with one hd and one dvd).

I internally added a second hard drive and a 2nd dvd.

The PC recognizes only these 2 new devices only as non-funtional icon:
Removable disk and DVD.

I've try to get into the bios at start (with F1, F2, DEL, F12) but not successful. I even tried to slow down the boot sequence with "esc" and Pause/break keys but no help.

What do I do?

Thank you.

Dell optiplex BIOS access key is either F2 or Del. If you can't access it by using those keys, your CMOS must have gone corrupt. You need to flash it. Just remove the CMOS for some seconds and put it back, than you will be able to enter setup.


Hope this helps.

what's a CMOS and (where/how) do I flash (what does this mean). I'm at my PC can you walk me trough the procedure.

Sorry about the delay, was away for a while.


CMOS is a flat battery located in your motherboard. Flashing CMOS means just removing it for sometime and than placing it again.

I can see a 3V nickel-size round battery on the motherboard. Is this the one.
So the question is do I remove it before boot up or after boot up (when the computer is on)? Thanks.

Don't touch it when the computer is on, you may get a shock. Turn the system off, remove the battery for 10-15 seconds, put the battery back. Now try to go into BIOS.
