How do I initiate BIOS Recovery on a Dell desktop or all-in-one computer?
Restart the computer.
Press and hold the CTRL key + ESC key on the keyboard until the BIOS Recovery page appears.
On the BIOS Recovery screen, select Reset NVRAM (if available) and press the Enter key. Select Disabled and press the Enter key to save the current BIOS settings.
Select Recover BIOS and press the Enter key to start the recovery process.
Note: Your Dell computer may restart a few times during the process of BIOS recovery.
Are you seeing a password request when you're trying to get into BIOS? If the BIOS is locked, and you need a password to unlock it, you would need to contact Dell's Tech support. We can't provide help for passwords via the forums, as you would need to prove ownership of the system to get help.
If you're able to get into the BIOS you should be able to locate an option to reset the BIOS to factory settings, and I suggest you do that. (I don't have a copy of the BIOS for the 5547 that I can review so I can't give you directions on where to find the reset option)
Please give me a bit more information on where / when you're seeing the BIOS locked and I'll see if I can help you a bit more.
Thank you for replying! I haven't seen any password and the update has mysteriously vanished. The laptop is working fine except sometimes, when I shut down or hibernate, the fan keeps spinning and sometimes it drains the battery.
Do you think I should reset the BIOS or should I just leave it as it is?

You can update BIOS without Windows if you create a bootable FreeDOS USB flash drive.
