There's a switch, you look for it, there's a light-like button on the keyboard, and then hold down the fn key and press that button, and it turns on. Or click on your battery icon and select High Performance, if this can't be adjusted, because there is a wire inside the keyboard that is estimated to be loose. First you can try the fn + spacebar (enable or disable the keyboard backlight).

Sometimes the auto-sensing backlight does not work, you need to go to the window mobile center to turn off the keyboard backlight and then restart the system, the keyboard automatic sensing function will work, confirm that the background light detector control for the keyboard backlight is enabled on the check, and make sure to restart.

Solution: 1. If the keyboard light does not light up, first wipe the memory module with an eraser, and check whether the gold finger of the memory module has any burnt marks. Replace the memory in the slot.

2. Check the capacitors and resistors on the motherboard to see if the capacitors are bulging, whether there is a burning smell on the motherboard, and clean up the dust on the motherboard.

3. Remove the CPU fan, power on and turn on, test whether the CPU has a temperature change by hand, if not, the CPU is not working, either the motherboard is broken, or the CPU is not plugged in properly, and the CPU is re-plugged.

4. Power supply problem, although the power supply is powered on, but the motherboard can not work normally, replace the power supply and try it.

6. Minimize the test method, only leave the power supply, motherboard, CPU, memory, graphics card, keyboard, monitor, unplug all the wires on the rest of the motherboard, use a screw knife to short the switch pins, if normal, add the rest of the hardware, piece by piece, until the cause of the problem is found.

The indicator light of the keyboard is not lit, in most cases it is not caused by hardware damage, but because the corresponding keys are not pressed, the three indicators on the keyboard correspond to the three modes of the keyboard, when the corresponding keys are pressed, they will light up, and the keys of the control indicator are the caps lock in the main keyboard area and the num lock in the keypad area and the scroll lock in the area (in the order of the indicator from left to right).

If the keyboard indicator is not lit because the corresponding key was not pressed, then it could be something else. First of all, please make sure that the computer keyboard cable has been connected to the computer motherboard interface normally, and then confirm whether the computer's motherboard and interface are damaged, or whether the connection cable is broken.

If you are sure that all the interfaces are fine, then try pressing the corresponding button of the keyboard light to see if it works, such as the caps lock key, numlock key, and scroll lock key. If the above methods still do not work, then it is very likely that your keyboard indicator has been damaged, if it does not hinder your use, it is recommended to continue using it, or replace it with a new keyboard.
