Method 2: editing registry
Make the following modifications to the registry for the class of device affected
- (in this case keyboard). There may be a number of sub keys with the string: {4d36e96b-e325-11ce-bfc1-08002be10318} at the location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4d36e96b-e325-11ce-bfc1-08002be10318}
- When you have found the correct instance modify the “Upperfilters” Value to:
“kbdclass” without the quotes. Then restart the machine. - Check in device manager to see if the keyboard is now working.
Other things to consider
• If the above does not help you may need to consider whether either:
• The keyboard has spontaneously malfunctioned (unlikely if all keys are dead)
• Whether liquid damage may have occurred to stop keyboard operating.
