Sticky or Unresponsive Keys ¶
The laptop's keys are sticky or unresponsive or appear to be broken or missing.
Dirt and Grime causes the keys to stick or break ¶
If the damage does not warrant the use of a cleaning kit, then use a can of compressed air and blow the dirt out of the keyboard.
If this is not successful ¶
1. Take a keyboard cleaning kit and clean the dirt and grime out of the keyboard thoroughly. Using the scrubbing tool included in the kit, scrub the dirt between keys out of the keyboard.
2. Clean up the grime that the tool was unable to clear out using a cleaning solution and wipe off after applying it to the keyboard.
If neither one of the solutions solve the issue ¶
You may need to remove the keyboard from the device manually and thoroughly clean the palmrest keyboard before reinstalling.
A key has fallen out of the keyboard ¶
Search for and install a replacement key where the missing key is located. For example: The product has shipped to your residence or business without a Windows key. If that is the case, then simply install the key on the blank location by attaching the retainer clips to the key along with the metal hook if needed. Be sure to push the key down evenly on all four sides in order for the clips to perfectly attach to the replacement key.
