The 3 keys of the computer keyboard cannot be pressed at the same time

A malfunctioning keyboard is broken.

First to the after-sales maintenance, maintenance does not work, external keyboard.

The keyboard is divided into membrane ordinary and mechanical keyboards. Ordinary keyboards have a shorter lifespan, and this phenomenon is aging.

Each key of the mechanical keyboard is an independent mechanical switch, and the switch is controlled by a metal spring, so it will have a longer life than the membrane keyboard, and there will be no aging after a long time. In this case, it is recommended to make an external keyboard.

If you press it for a long time, those three keys will be damaged, and if it doesn't work, you may have to change the keyboard.

It's normal......

This has a lot to do with the layout of the keyboard's wiring and the software drivers.

In the past, when we used the keyboard to play "The King of Fighters 97" in our dormitory, we often locked the keys, and the degree of lock keys and key combinations of different simulators were different.

Now some keyboards are specially designed for CS, Warcraft, etc., to ensure that commonly used keys will not lock keys to the greatest extent, but it is estimated that no one has designed a keyboard for "Super Dance" yet.

Keyboard hooks" program is doing tricks, other programs truncate such shortcuts!

There is no problem with your keyboard. Good luck

If your keyboard has a proprietary driver, install it!

It could also be that you have a problem with the sequence of key combinations!

Try a few keys with the test in the super dance.

Water ingress into the keyboard. Hehe.

There are several workarounds for keyboard key failures:Tools Ingredients: Hardware: Computer, System: Windows 10 Home 64-bit processing system.

1. Open the control panel, and change the viewing mode to a small icon.

2. Click the keyboard.

1.Disassemble the keyboard. Note that when opening the keyboard, be sure to button the side (that is, the side we operate) down, the circuit board up, otherwise the conductive plastic on each key will fall off, bringing trouble to your rental repair.

2.Turning over the circuit board, the circuit board is generally made of a film made of soft plastic, which is engraved with a button arrangement, and the concentration of more than 97% nano-type alcohol cotton (75% medical alcohol.

Cotton can also be used, because I have used it, but the best way to eliminate it is to use high-concentration alcohol cotton) to gently scrub the road slab twice. Take care of the key failure part of the circuit several times.

The buttons in the first row are generally multi-function buttons, and you need to hold down the fn button in the lower left corner and then press those keys to take effect.

It can also be set in the BIOS to operate without pressing the FN key.

What happens if the laptop keyboard doesn't respond What to do if the keyboard fails:

First of all, when we encounter this situation, don't jump to the conclusion that the notebook is broken, in fact, sometimes it may be that the system is processing too much data and the system is in a state of suspended animation, so that the keyboard does not respond, then we should think of restarting the computer first.

If restarting doesn't solve the problem, we should think about whether there is a problem with the driver. Take the Win7 system as an example: click the [Start] button in the style of the Windows icon at the bottom of the left to enter the list option box area.

Enter the control area of your computer. Select and click [Keyboard] to enter the properties interface of the keyboard.

Click on the [Hardware] option and check if your driver is working properly. If the driver does not run normally, you need to uninstall and reinstall the driver.

If reinstalling the driver still doesn't solve the problem, it is likely that the internal driver of the computer is conflicting. Before booting into the system, press F8 to enter the Advanced Boot Options area of Windows 7 and perform a factory reset.

If it still can't solve the problem of source mu, it is recommended to send it to a computer repair point for repair. Generally, computers have a warranty period, and some fees will be charged if the warranty period is exceeded.

Initially think it's alt pressed.,You take this button out and try it.,The buttons of the notebook are normal, and you won't unilaterally break the hunger socks no matter how you get it.。

It may be a keyboard key conflict, the key conflict is not a setting can be solved, the keyboard design caused by the key conflict is basically unavoidable, basically all keyboards have more or less key conflicts.

It is possible that the keyboard is damaged, and it is recommended to repair it.

A keyboard is a kind of instruction and data input device used to operate the equipment, and also refers to a set of function keys (such as typewriters, computer keyboards) that are arranged to operate a machine or equipment by the system. The keyboard is also part of the musical instruments that make up the keyboard, and it can also be used as a musical instrument that uses the keyboard, such as a piano, digital piano or electronic keyboard, etc., and the keyboard helps to practice typing.

The keyboard is the most commonly used and most important input device, through which English letters, numbers, punctuation marks, etc. can be input into the computer, so as to issue commands and input data to the computer. There are also keyboards with various shortcuts, but at first they were mostly used in branded machines, and were once seen as a feature of branded machines.

Determine if a key is jammed. Try tapping different keys on your keyboard to see if a key is stuck.

If it doesn't look like a key is stuck, check for a hardware conflict about your sound card.

Specific workarounds:

1. Reset the arrow keys to the other four buttons, such as W, A, S, D.

2. Change the keyboard, buy a keyboard with seven keys that do not conflict, and press seven at the same time will not conflict.

3. Two different sockets can be used, the mouse is allowed to be used, and the conflict domain of the brand-name keyboard is very small.

This can only be bought to support 3 keys at the same time without conflicting keyboards. But it seems that there are not many people who need this type of keyboard, because very few people will often press 3 keys at the same time. I don't know if there is a software that supports the keyboard to press 3 keys at the same time without conflict, you go to the Internet to find it, if there is, congratulations!

If you want to play dnf, you can change the keyboard.,TX is in this format.,I only know it's harmful.。

It is recommended to buy a better one, and there are many keyboards that do not support the use of multiple keys at the same time. According to the principle of keyboard design, key conflicts are basically unavoidable at present, regardless of the grade, basically every keyboard has more or less key conflicts. However, you can test it out with a software called keyboardtest when you buy a keyboard.

After installing this software, you only need to press the most commonly used keys at the same time and release them according to your own usage habits. If there is no key conflict, the key will be green at this time, and if there is a conflict, the conflicting key will not change color. This makes it easier to detect key conflicts, and you only need to buy a keyboard with the least conflict according to your habits.
