The BIOS default password is just blank, and it is not asked.

When you set a bios password, you are asked to enter a value, therefore if bios is asking the password, the password had been changed.

To reset the bios password if you do not know the password you need to access to motherboard and temporarily remove battery for few seconds.
Removing battery will reset bios and delete the password.
Unplug power cord before accessing the motherboard, and try not touching the motherboard with your finger.
Put battery back in place before restarting computer.

Password admin bios


Reset the CMOS by unplugging your Optiplex from the power cable & removing the CMOS battery.
The CMOS battery is just a larger "watch battery" about the size of a nickel. Remove it for a few seconds, put it back in & power it back up. This will reset the BIOS password & restore all the BISO settings to default however.

Dell optiplex desktop freezes up at boot screen. Says drive 2 not found. Bios setup is correct and boot sequence has been setup correctly. Was working before but now freezes up.


Swap out the ram one stick at a time, bad ram has been known to cause this type of symptom, the other thing to check is the motherboard, check the led light on the board is green, if not and it is yellow or amber indicates motherboard issues.

Bios password removel of Dell Optiplex GX280


If you don't know the BIOS password, and need to access it - you'll have to unplug the AC power then open the case and remove the lithium "coin" or "button" battery from the motherboard. Wait 5 - 10 minutes (allows the capacitors to discharge) and replace the battery. This will RESET all BIOS values to default.

Restore AC power reboot. Enter the BIOS and change the values as desired. To access the BIOS, Press the F2 function key repeatedly during boot sequence. You may need to plug the USB keyboard into a different USB port if it doesn't let you in to the BIOS page.

I hope this helps & good luck! Please rate my reply - thank you.

Generally an indication that the Hard Drive isn't detected
Things to check, go to BIOS F2, reset defaults and reboot, see if the HDD is seen. If it is, the battery on the motherboard is likely dead and needs replacement (Watch battery at Walmart, 3 dollars)

Unable to upgrade onboard graphics on dell gx520


Try disabling your onboard graphics in the BIOS. Some BIOS allow this. If you have a sound card, disable the onboard sound too. Count your beeps. they contain a code. Go online and "Google" bios codes. This should give you a starting point to diagnose the problem.
