Laptop: Dell Latitude E6410

Win7 keeps looping and sometimes freezes at Windows loading logo and I'm trying to use the restore cd but cant get into the BIOS to enable dvd-rom. I forgot the admin bios password to unlock, even tried removing the coin battery to no ava, I think its a chip that has to be removed to hard reset.

System Number: G2CLXN1-2A7B

Dell support isn't helping at all and keep telling me to run diagnostics, which everything Passed. They said they would charge to send a tech out to remove password but that's gonna make me wait longer and probably cost me a bundle. Does anyone know where there is a battery or chip or jumper on this mobo to remove the pass?
