1. Function Keys Aren’t Working
Whenever the function keys do not work, the problem could be that you have a function lock or F-Lock key that has to be toggled. The F-Lock key is applied to power on or off the F keys, right from F1 up to F12, or secondary functions of the F keys.
2. One or More Keys Don’t Work
It’s quite obvious that hair, dust, dirt, and other debris can fall into the keyboard over time and prevent a key's movement or meddle with its circuitry. For an effective laptop repair in South Riverside, or elsewhere, you should try to remove the key that isn't functioning, and clean the area under and around it.
Whenever you find that cleaning under and around the key doesn’t fix its functionality, the circuit board in the keyboard is possibly faulty or damaged. A poor circuit board may lead to the improper functioning of one or more keys to no functioning at all. If the circuit board is defective, then the keyboard must be replaced to fix the issue.
3. Certain Keys Aren't Used in Specific Programs
Particular keys, like the function keys ranging from F1 to F12, do not function with every application. Assess the key that isn't functioning in more than a single program, like a word processor, Notepad, and your favorite google chrome. When the key works in other programs, then that key doesn’t have any utility in that particular program.
4. Keys on the Number Pad Aren’t Working
When the keys on the number pad fail to work or behave strangely, such as moving your cursor, then press the Num Lock key. Num Lock is applied to switching between the primary function (e.g., numbers) and secondary functions (e.g., Home, arrow keys, Delete, etc.) of the numeric keypad.
When your keyboard features an LED indicator for the Num Lock key, the light should be powered on if the numbers can be typed.
5. Key Not Performing Expected Action in a Game
Whenever you face any issue with a key working in a game, ensure that the key is mapped properly. Every key can be mapped to a different action through the game keyboard settings as a crucial task for your laptop repair in Lake Elsinore or other locations.
6. Program or Driver Interference
Attempt rebooting your device. It isn’t uncommon for a program or operating system to create problems with a keyboard preventing a few of the keys from functioning.
If rebooting wasn’t of any use and you're using Windows, try to start the laptop in Safe Mode to ensure that no background programs are running. When your keyboard works in Safe Mode, it's maybe that one of the installed programs or device drivers is the root cause of the issue.
You may try to disable or remove background programs, or TSRs, to figure out which one may be preventing some keys from working.
Checking whether there are any updated device drivers for your laptop. Installing updated drivers may solve problems related to driver conflicts preventing some keys from working.
