After the win10 update, some keys on the laptop keyboard failed. After trying all the solutions obtained after asking questions on the Internet and the Chinese Microsoft community, it still didn’t work.

Dear all, My laptop is HP’s ZHAN 66 G1. After the win10 update, some keys on the laptop keyboard failed. However, after using the external keyboard and unplugging the external keyboard, the previously malfunctioning built-in keyboard keys can also be used, but after a while, the same keys of the built-in keyboard will be invalid again, but the time is different each time . I have used the following solutions: 1. The situation has not improved after using the "Start Fast Start" in the power-off settings written on the Internet. 2. I have also used the method of closing the startup item, but it is also ineffective. 3. I also tried the method of uninstalling the keyboard driver and then updating it, but it didn't work. 4. The USB driver has also been updated and it is useless. 5. This problem has not been improved after updating to the 20H2 version. --------------------------------------------------------------------------------------------------------------------------------------------------- Later, after a certain system update and HP keyboard driver update, the keys that failed before suddenly all worked. But after a while, it failed again, and the failed keys were the same as before, mainly a, s, d, l, k, 4, 7, + and other keys. After this failure, I have tried four solutions, The first one, after trying it, the WIN emblem key really does not work well, which proves that it is not a hardware problem. But it did not solve the problem, the problem remains. Please open the registry editor while keeping only the built-in keyboard of the notebook, and find the following subheadings: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout\ In this subheading, look for a binary item named "Scancode Map" (should not be there). Please create a binary item with this name first and set it to the following binary value: 00,00,00,00,00,00,00,00,02,00,00,00,00,00,5B,E0,00,00,00,00 Click "OK" and restart the computer. If your keyboard hardware is normal, the Win logo key on your left keyboard will be unresponsive. This ruled out your hard disk hardware problems and refreshed the key-value registration. Then, please find this subkey again and delete this subkey you created. Then, restart the computer to test whether your keyboard is back to normal. the second, After repairing the system through sfc /scannow, there is indeed a prompt of successful repair at the beginning, but the keyboard still fails. After several attempts, it has been prompted that the system is intact, but the keys still fail. The third, I also tried to solve the problem by creating a new administrator account, but it still didn't work! Fourth, using Media Creation Tool which is downloaded from the Microsoft to reinstall the system, but it did not solve the problem. This problem has troubled me for a long time, and I hope to get help from experts. Thank you! Sincerely yours, Jianing
