How To Crack a BIOS Password

Desktop :
*. Power off the computer and make sure that it is unplugged.
*. Open up your computer case. You need physical access to the motherboard to complete this procedure.
*. Find a circular, (mostly) silver metallic object on the motherboard. This is the CMOS battery.
*. CAREFULLY remove the CMOS battery, avoid touching it with your fingers, and leave it out for about 700 seconds. This will flush the CMOS memory which stores the BIOS password and all other configuration. (See Warnings)
*.Set the battery back into place and power on the computer.
*.The computer should then warn you that the CMOS configuration could not be found. You can either reconfigure it yourself or restore defaults. Restoring the default configuration should be fine.
*.You will notice that the BIOS password has been cleared and you can boot without it. You may reset the BIOS password to something else by going into the BIOS configuration and setting a new User Password (The Supervisor Password controls access to the BIOS, NOT the computer!)

Fix HTTP Error 502 Bad gateway

This problem is due to poor IP communication between back-end computers, possibly including the Web server at the site you are trying to visit. Before analysing this problem, you should clear your browser cache completely.

If you are surfing the Web and see this problem for all Web sites you try to visit, then either 1) your ISP has a major equipment failure/overload or 2) there is something wrong with your internal Internet connection e.g. your firewall is not functioning correctly. In the first case, only your ISP can help you. In the second case, you need to fix whatever it is that is preventing you reaching the Internet.

If you get this problem for only some of the Web sites you try to visit then it is likely to be a problem at those sites i.e. one of their pieces of equipment is failing/overloaded. Contact the people at those sites.
