There is a problem with the desktop computer keyboard at home, and pressing a key has to type out a

Isn't it also flooded?。。 If it's not water ingress, then the circuit board is damaged. Let's get a new one.

I'm pasting my answer to another question for your reference.

Well, depending on your keyboard symptoms, it may belong to a keyboard circuit that is not sealed and protected, that is, it is not a waterproof keyboard, and if the circuit fails after water ingress, it will happen that if you press a certain key, it will standby, or shut down, or several letters appear. As long as the water is ingress, the entire circuit will change, so it is not that the water is soaked to the **** before the problem occurs.

If you are willing to repair, please prepare a small screwdriver of the Phillips, remove the screws that can be seen on the keyboard, please keep the bottom facing up, do not let the things inside fall out, there will normally be a plastic-like circuit board inside, and there is a bunch of plastic hats for each keyboard, it is by this that the keyboard is pressed down and bounced up, carefully remove the circuit board, and then separate the upper and lower layers, in order to be able to restore the original state, do not separate them all, leave one side with a clip, keep the position, Carefully dry the inside with a paper towel and let the two boards separate, let it dry overnight, make sure the water is air-dried, and then put it back in its original state, OK.

Of course, if you're in Shenzhen, uh. Looks like it can help.。。

It's better to find a boy to do coolies, and the best way is to do it. Buy a new one. But... But if you can fix it... It's really not necessary ... Hope!

Press fn plus numlk to toggle it. When switching to digital, it is for the convenience of a large amount of data on the computer.

Fn+NUML press once.

The reason is that I have switched to numeric shortcuts.

Hello dear, it is a pleasure to serve you! Answer: If your desktop computer keyboard has the problem of multiple identical letters appearing when you press once, you can try the following methods to solve it:

1.Check the keyboard connection: Make sure the keyboard is connected to the computer stably, and the plug is not loose or damaged.

2.Clean the keyboard: Use compressed air or a small vacuum cleaner to clean the inside of the keyboard to remove dust and dirt that may cause the pressing wheel keys to fail.

3.Replace the keyboard: If the problem persists after cleaning the keyboard, you may need to replace the keyboard.

5.Check the operating system settings: On Windows, open the "Control Panel" and select "Keyboard" to make sure that the "Repetition Delay" and "Repetition Speed Limb Signal" settings are correct.

If these settings are incorrect, they may result in duplicate keystrokes. 6.Check the key settings:

It may be that some keys are set incorrectly, such as the key repeat function setting to turn on the brother grip. You can adjust the settings accordingly in the Keyboard in the Control Panel.

Desktop computer keyboard , type a letter, come out a large string, what to do if you don't control it.

If you press several of the same letters or different letters, the same letters may appear for a little longer and your keyboard is too sensitive. But I think it's very likely that your keyboard is rejuvenated and garbled to leak and cause me to come up with a few different letters, in this case you can cut off the keys on the keyboard (you can cut it off, it won't break) and wipe it clean with a clean cloth!If it doesn't work, you can change the keyboard!!
