6. The notebook keyboard is faulty, and the keyboard needs to be detected or replaced.

First of all, it may be caused by the user's careless operation. Hardware issues include that because the number keys and letter keys of the laptop keypad are integrated, generally pressing the fn numlk key can intelligently switch to the small numeric keypad. Sometimes we press the letter key to turn into a number.

All those who buy notebooks should read the manual.

Of course, this mistake can be solved at once, but if it still doesn't work, then it may be that the keys are out of order, and sometimes, when we press the keyboard, there will be a lot of messy letters or numbers. That may be the reason why one of the keys was pressed and didn't pop up, so the keyboard was checked and ruled out one by one.

If the laptop's keyboard doesn't work, it's likely that there is something wrong with the laptop and the computer needs to be repaired. It's also possible that the keyboard has poor contact.

If the keyboard does not respond, the first thing to see is whether the keyboard has been connected to the computer's interface. Because if you've ever opened the case, you've probably forgotten to plug in the keyboard connector.

Then what should be considered is the hardware, which is the keyboard itself. First, check if the keyboard cable is damaged or disconnected. If there is damage, just connect it. If your keyboard is wireless, check to see if it's out of battery or if the transmitter is set up improperly.

If the keyboard itself is not damaged and the connection is normal, consider whether the driver was deleted by mistake. Because the keyboard drivers come with the operating system, it is easy to restore the driver after it is deleted. Open Device Manager and find the Keyboard option.

In the keyboard properties, there is a button to update the driver, you can click this button to update it and give it a try, if it is indeed because of the driver problem, the problem should be solved after clicking.
