Description: After turning on the computer, the keyboard light flashed, and then the light did not turn on, and the keys did not respond. Shut down, unplug the keyboard, then plug it back in, restart the computer, and the problem persists.

Open the control panel and look at the keyboard, but you can't find the hardware. Clicking on the troubleshooter and properties didn't make any difference.

Then I took the keyboard to the repair computer, and the keyboard turned out to be fine, could it be that there was a virus in my computer? With 360 security guard and 360 antivirus, the problem is still not solved. As you know, it's not easy to get these things done without keyboard operation.

By this time, I was exhausted. Holding the tea and drinking it violently, oh, I understood: "The keyboard is good, and the system has no virus, so there is only one thing that goes wrong, and that is the keyboard interface on the computer".

Yes, with the mentality of giving it a try, I unplugged the keyboard and changed it to an interface, hehe, the keyboard is finally usable.

Tips: To sum up, we have come to this experience, the keyboard is generally not easy to break, and the problem is mostly the computer interface, such as loose or dust and other impurities accumulation resulting in poor contact, or because the dust is not cleaned for a long time and some aging lines are short-circuited, etc., resulting in the computer interface can not be used.
