Updated Failed NVRAM was invalid but was unable to be updated. Keyboard Error Error in the keyboard connection. Make sure keyboard is connected properly. KB/Interface Error Keyboard interface test failed. Memory Size Decreased Memory size has decreased since the last boot.
Error Messages and Beep Codes 4.2 Port 80h POST Codes During the POST, the BIOS generates diagnostic progress codes (POST-codes) to I/O port 80h. If the POST fails, execution stops and the last POST code generated is left at port 80h. This code is useful for determining the point where an error occurred. Displaying the POST-codes requires a PCI bus add-in card, often called a POST card. The POST card can decode the port and display the contents on a medium such as a seven-segment display.
