Hi
You might be lucky and this applies....
Power off, unplug, remove side cover.
Remove the coin-cell CMOS battery for ~5–10 minutes, then reinsert.
Optionally use the PSWD jumper on the system board (if present) per the service manual to clear passwords.
Reassemble and power on.
You may need to "GET HELP NOW" blue button and deal with Dell about ownership and chargeable fee.
Kind Regards
