When the keypad light doesn t turn on, you have to press it every time, it s troublesome

It can be set in the BIOS settings. boot up numlock status, just change off to on. Some BIOS are called Keyboard Numlock.

Summary. This is the reason for the keyboard, which leads to the typical failure phenomenon of the computer "crashing", and there are generally two reasons for this failure. The first is that the driver of the keyboard that comes with the system is corrupted, resulting in the keyboard not being recognized by the system normally, or the hardware resources allocated by the keyboard in the system conflict with other hardware, causing the fault, the solution to this fault is as follows:

1. Right-click "My Computer" and select "Properties"2, find "Keyboard" in the "Device Manager" window that opens3, uninstall the keyboard driver4, and then automatically install the keyboard driver again (click the shortcut button under the title bar of the window - the computer icon with a magnifying glass). The second reason is the hardware problem of the keyboard itself that causes the failure, and the solution to this failure is generally to replace the keyboard with a new one (maintenance is not recommended, the keyboard generally does not have much repair value, and the maintenance cost is enough to buy a new keyboard).

Why does the keyboard light turn on once and then it doesn't light up.

I would like to ask how the lights of the mechanical keyboard are turned on. It can light up when it is turned on, but it will not light up after turning it on.

Hello dear, happy to serve you <>

If your mechanical keyboard is able to light up normally when it is turned on, but it cannot light up after turning it on, it may be because your computer system has turned off the light function of the keyboard by default. In most cases, you can turn on the lights of a mechanical keyboard by following these steps:1.

Press the "fn" key on your keyboard (usually in the bottom row) and press the light control key on your keyboard. The light control keys will usually have an icon for the sun or light bulb. 2。

Check your computer system's settings to make sure the keyboard light function is turned on. You can find the relevant configuration disadvantage options in your computer's control panel or settings. 3。

If your mechanical key Pecha drive has software or drivers, open the software or driver and see if you can control the keyboard's lights through the software or driver. If you still can't turn on the keyboard's lighting function after trying the steps above, we recommend that you check the keyboard's user manual or contact the keyboard manufacturer for more help.

According to your account, it is likely that the reason appears in six aspects:

First, there is a problem with the power supply of the computer, such as the switch transistor, fuse, rectifier diode, filter large capacitor, and so on. Reconnect.

Third, there is a problem with the boot circuit of the motherboard, generally the triode, capacitor, and resistance of the boot circuit, and there is a problem with the IO, and there is a problem with the CPU power supply circuit, etc., as long as these original components are replaced, it is OK

Fourth, the gold finger of the memory and graphics card in the host is oxidized, resulting in poor contact between the memory and the memory slot, and the poor contact between the graphics card and the graphics card slot, resulting in hardware incompatibility, which leads to the inability to boot. Solution:You can turn off the power first,Open the compartment,Dial out the memory,Use the eraser to the part of the gold finger (that is, where there is a copper sheet,) wipe back and forth a few times,Then change a memory slot and insert it back,It's OK,If there is an independent graphics card,You can also use the same method to deal with the graphics card,Just don't change the slot,It's OK,Fifth:It's a problem with the boot twist on the host panel (such as can't bounce up, it's broken),It can't be turned on,Lead to can't turn on, Replace the torsion or change the cable, the sixth is: There is a problem with your graphics card, such as the video memory of your graphics card is soldered, the connected transistor of the VGA, the chip resistor, and the capacitor are not enough The power supply of the control chip is insufficient, and there will be a crash, restart, abnormal display, and cannot be turned on, etc., so it is recommended that you repair the graphics card, that is, repair the graphics memory, or replace the graphics card. Among them, you should pay special attention to the fourth situation, which is 80% of the cause of the host computer not being able to turn on.

The interface is broken, or the keyboard is broken. Try the keyboard with another machine.,The interface is broken.,Just change the keyboard with a different interface.。。 If the keyboard is broken, then I can't do anything about it.

Reboot it and try it, mine is fixed like this.
