1, first see whether the system CPU and memory load is too high, resulting in the computer stutters and make the keyboard slow response. If so, let's clean up the running programs and get rid of the useless processes.
2, if it is not the CPU and memory load is too high, we can first replace a new keyboard to try to see whether the keyboard itself is faulty.
3. If the problem persists, let's go on to find the reason. Then, let's see if there are charging devices near the computer host, such as display power adapters, notebook power adapters, digital product chargers and so on.
4, if the above mentioned electrical equipment near the host, let us first power them off, and then go to see whether the computer keyboard input is normal. If we're lucky, the problem will be solved quickly. Why is that? Because these connected devices appear to work normally, but if their filtering circuits cause problems, the electromagnetic interference generated will cause the symptoms of slow keyboard input.
5, if the above problems are eliminated, consider replacing the system, eliminate the system failure. Of course, before we do the system, we can change the computer to a different space environment test (change rooms or move to a friend's house test) to eliminate the possibility of unknown electromagnetic interference.
1, first of all, if there is no accident, this is because our computer launched the \"filter key\" to my Windows 10 as an example to open the control panel.

2, Click the desktop assistant, open the Easy Use Settings Center in the control panel, browse all Settings and find the keyboard icon.
3, click the keyboard icon behind the \"Make keyboard easier to use\
< br \/ >

4, and then find the \"filter key\" in the options below, as the above picture to cancel the √, after typing will not delay the input.

5, WIN7 keyboard press a few seconds to type, you can try: Control panel - Easy access center - make the keyboard easier to use - set the filter key - set the repeat key and slow key - change to zero seconds.
