I have a Dell xps m140 that I have forgotten the bios password to, I tried removing CMOS and now I get a black screen that says invalid configuration use setup but nothing is working. #181XT91-595B this is the code I'm getting on login screen. Your help will be appreciated, thank you.
You will need to contact Dell Support by phone for resetting the bios password. They will verify ownership and then provide information for resetting the bios password or clearing it.
