Hello all, I bought Dell precision m4500 from craigslist and apparently the bios supervisor password is set and the laptop bios is locked. I installed windows 7 x64 and the laptop is working fine but if I run Ubuntu the system hangs and doesn't respond even with the newest drivers installed. The issue is, the laptop hangs from time to time and that's because of an outdated BIOS revision. The current bios is A05 and the latest is A15. I'm trying to update the bios from A05 to the latest to resolve the issues. I made some research and found some websites offering the backdoor password for free. i tired entering my service tag and the passwords generated didn't work. Below are the urls for the bios password recovery. http://laptoplabcalicut.com/laptopservicecalicut/bios/biospassword.html http://dogber1.blogspot.in/2009/05/table-of-reverse-engineered-bios.html http://bios-pw.org/ Is there a workaround to update the bios without the use of password? or is there a way to remove the password? I found a utility to dump the bios. Not sure if this will help in recovering the bios password. Also, I was able to extract the hdr file the bios update. Idea please? Also, i found some utilities such as Hiren Boot dics etc.. to recover bios passwords. none worked.

Request your help in finding, recovering, cracking etc.. the bios password. Thanks in advance.
