Dell Latitude 5400: Dell Latitude 5400 BIOS Administrator Password Reset - Second Hand Device

Sat, 27 Jun 2026 11:40:21 -0700

I purchased a second-hand Dell Latitude 5400 (UK used), but the BIOS is locked with an administrator password. I cannot change boot settings to install a new OS.

I have already tried:

1. Removing the CMOS/coin-cell battery for several minutes (did not clear the password).

2. Entering the wrong password to get a hint (I have the Service Tag, but the master password generators I found online haven't worked yet).

Is there a specific jumper on the motherboard for this model to clear the PSWD, or is the password stored in a non-volatile chip that requires a BIOS chip programmer to clear? Any advice from technicians who have handled this specific model would be greatly appreciated.
