The computer changed the power supply, everything else was normal, and the keyboard did not respond

The failure of the computer keyboard may be due to: forgetting to plug in the keyboard interface, the keyboard itself has problems, mistakenly deleting the driver, and the driver is too backward, which is detailed as follows

1. If the keyboard does not respond, the first thing to see is whether the keyboard has been connected to the interface of the computer. Because if you have opened the case, it is likely that you have forgotten to plug in the keyboard connector.

2. Then what should be considered is the hardware problem, that is, the problem of the keyboard itself. First, check if the keyboard cable is damaged or disconnected. If there is damage, just connect it. If the keyboard is wireless, check to see if the battery is dead, or if the transmitter is not set up properly.

3. If the keyboard itself is not damaged and the connection is normal, consider whether the driver has been 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.

4. The driver is too backward, in the keyboard properties, there is a button to update the driver, you can click the update button to give it a try, if it is indeed because of the driver problem, the problem should be solved after clicking.

Note: 1. You can use a third-party tool or use other tools to detect and install the missing driver on the computer.

2. Many problems can be solved by restarting the computer, and restarting the keyboard after connecting it to the computer may solve the problem.
