"This is a system board POST/BIOS error code. The ERROR 210: is a standard POST (Power On Self Test) errormessage that indicates an error with the keyboard.
The error condition is thata keyboard scan code was received from the keyboard when none was expected,after the keyboard was reset. If this occurs most of the time when you power on yoursystem, then it indicates that a key is sticking down or the key mechanical orelectrical parts are broken.
Sometimes blowing out and cleaning out around thekeys will resolve this problem. Otherwise, you need to replace your keyboard with a new (or at least a working) one.!
