Need to clear CMOS password on Inspiron 1525 laptop

You'll need to clear all custom settings from the BIOS. You can do that by removing the CMOS Battery located here http://support.dell.com/support/edocs/systems/ins1545/en/SM/coinbatt.htm#wp1179886

Additionally the entire service manual is located her for further reference:

Removing the CMOS battery will not reset a bios password on most modern laptops as the password is stored in NVRAM. To reset the password on a Dell laptop you'll need to contact Dell and after providing proof of ownership they will be able to assist in resetting the password using a master password that is system specific. The other option is replacing the motherboard.

Even though it was out of warranty, I begged Dell to give me the backdoor password without the $59.00 charge, and after 5 minutes of pleading, a supervisor relented, and they gave me the password.

Thank you. I would not have called because of the warranty problem, but after you suggested it, I tried it and got it resolved.

I was the first to suggest contacting Dell to get the master password.

Thank you, Jamietoner
