I have a Gateway Solo 5150 Laptop that I purchased at a garage sale. The previous owner's son set the BIOS passwords and I can't clear them. Does anyone now the manufactors "BackDoor" defaul password? It's using PhoenixBIOS 4.0 Release 6.0. Can anyone help ??

Have you tried removing the cmos battery? You have to wait several minutes for the password to clear?

You bought a computer without turning it on?

Call the previous owner and get the password.

every computer has a default pasword look in googles i have also herd that there is a program that will remopve this .
: If its a BIOS pasword, locate the CMOS jumper and short it across the middle two pins for ten seconds, put it back and restart the password will default to disabled.
: : I f a Win password, boot to an A:> with a start up floppy and change to C:, locate the files ending .pwl and delete them,probably in C:\windows\...restart and you will be asked for a new password, make one up and you will be in also search in www.googles.com

just take out the cmos battery as mentioned above. Some motherboards have a jumper setting that clears the CMOS so take a look at your documentation.

Should be easy.

OR crack it to use the default settings by using a program called "KillCMOS" you can git it here----> & its only 32kb! http://www.freepctech.com/pc/002/files001.shtml
