According to your description, I suggest you refer to the following information:
1. It is recommended that you uninstall the keyboard device in Device Manager, and then right-click any device and select Scan to detect hardware changes to see if this problem can be solved.
2. If the problem of the machine still exists after the above operation, I suggest you try to restart the machine. When the HP logo appears when the machine is turned on, press F 10 to enter the BIOS. After entering the BIOS, it is recommended to select Security, and then set the password to see if the machine can set the password with asdfjkl zxcvm and other keys.
A. If you can't set it with the keyboard, there is probably something wrong with the keyboard of your machine. It is recommended that you contact the local gold medal service center for testing and handling as soon as possible. For the contact information of the Gold Medal Service Center, you can choose your province and city and the product type you use through the following websites:
/zh/support-drivers/e support/as CPPS . html
B. If the settings are ok, the hardware problem of your machine is not serious. The problem you mentioned is probably that there is something wrong with the machine system. It is recommended that you can save important files and restart the machine. When the HP logo appears on the machine, press F 1 1 to restore the operating system of the next machine, and see if the problems encountered can be solved.
Note: If your machine does not have windows operating system pre-installed, it is recommended that you try to put it on the system installation CD to save important files, and then reinstall the operating system to see if it can solve your problem.
I hope the above reply can help you.
