if you can open the cabinet and there on the mother board you will find a CMOS battery (round one) take that battery and keep it out for around 3 mins and then put it back properly - start your computer - BIOS password will be reset .

Replace it with the same type of battery, then adjust the clock in the system setup.

All done, all fine.


Let me know if you need anything else.

Thanks,

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.

What is the default password to get into the BIOS, to set up the boot sequence...on a Dell Optiplex GX520 Desktop

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.

No boot device means that the computer cannot find a drive that has a operating system files and therefore cannot boot up.
This usually means that the hard drive in the computer is faulty.
You need to get a new hard drive and install Windows on the hard drive, together with the drivers for the computer's installed devices and programs to get a working computer.
