Keyboard failure, part of the keyboard keys on the keyboard failure, this is the failure of the keys without any regularity.
Caused by the failure of some keys of the keyboard, most of this situation is the failure of the internal circuit board of the computer keyboard, this phenomenon is generally due to the dirt on the road board or conductive plastic, so that the two can not be connected normally. Other factors are also possible, such as: damaged keyboard plug, faulty wiring, damaged motherboard, CPU not working properly, etc., but they are not the main cause.
The former can be solved by trying the following methods, and the latter is generally related to computer malfunction or keyboard malfunction.
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 one after another, causing trouble for repair.
2.Open the circuit board, the circuit board is generally made of soft plastic film, engraved with key lines, with a concentration of more than 97% alcohol cotton (75% medical alcohol cotton can also be used, but it is best to use a high concentration of alcohol cotton) gently scrub the road board twice. Take care of the key failure part of the circuit several times.
3.Check the conductive plastic of the failed part of the button, and if there is a large amount of dirt accumulated on the upper area, use alcohol scrubbing as well. Assuming that the conductive plastic is damaged, then the author suggests that the conductive plastic on the infrequently used keys can be replaced with the damaged part, although this "tear down the east wall to make up the west wall" measure can not make the keyboard play all the functions, but at least can extend the life of the commonly used keys.
4.To remove dirt from the inner corners of the keyboard, tools can be used with brushes, small brushes, etc., but pay attention to the gentle movements.
5.Check whether the soldering module is soldered or desoldered, and if you use an electric soldering iron, you can repair the soldering work. Of course, this step is only applicable to friends who can use an electric soldering iron, and friends who can't use it, please skip this step.
6.Install the keyboard. One thing to note here is that you must wait until the alcohol has evaporated.

The solution to the problem that the notebook keyboard can only type numbers and cannot type letters is:
1. Press the J, K, and L keys in the text document to test it, and the type is 3.
2. Find the "FN" key on your keyboard.
3. Find the "numlk" button on your keyboard.
4. Press the "FN" button with your left hand without letting go, and press the "numlk" button with your right hand.
5. If you enter the test on the text document, you can find that the letter button on the right side of the keyboard resumes the letter input.
Repair method for notebook keyboard that can't type:
1. First of all, it may be caused by the user's careless operation. Hardware issues include that because the numeric and alphabetic keys of the laptop keypad are integrated, 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 a notebook read the manual.
2. Of course, this mistake will be solved at once, but if it is still useless, 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 down and didn't pop up, so the keyboard was checked one by one.
3. Try to change the keyboard driver, by modifying the driver of the notebook keyboard. Mouse click on "My Computer" - select "Device Manager" to find the "Keyboard" option, usually the keyboard driver for the Murphy is "Standard 101 102 keys or Microsoft Natural PS 2 keyboard".
Then right-click on the keyboard driver, select the "Update Driver" option, the hardware update wizard will appear, select "Install from the list or specified location (Advanced)", click "Next", select "Don't search, choose the driver you want to install".
Then click "Next" to enter the "Select the device to install for this hardware" page, remove the checkbox before "Show compatible hardware" page. In the Standard Keyboard Model column, select Japanese PS 2 Keyboard (106 109 Key), click Next, Update Driver Warning pops up, and select Yes.
Confirm that the "Window Continue Window" of the device installation "Yes" can complete the hardware update wizard operation. Then restart your computer. <>

The keyboard can not be used in the following cases
1: If the external keyboard is not yet available, it means that there is a vulnerability in the system, resulting in the software and hardware can not be combined (very little) This system can be installed and installed.
2: The line connected to the keyboard has fallen or broken the hidden number.
3: Long-term use in a harsh environment (dusty, high temperature, humidity 、、、 stove to accompany the head) caused by the reduction of key sensitivity, or directly can not be used, in this case you can clean up the connection position under the collapsed keyboard, you can also directly replace the keyboard (I think it is too expensive to go to customer service, ** too high, it is best to find a reputable maintenance point to replace the keyboard, sensitivity and quality is not very different).
It is recommended that if you often use the keyboard for a long time, it is best to plug in an external one.

Always use an external keyboard. This seems to be a hardware solution only.
