What s going on with the keyboard light off?

1.Suppose you mean the BIOS has been set to automatically start the numeric keypad when powered on. However, every time you boot into the system, the keypad still does not turn on automatically, and needs to be turned on manually, and it is normal to use after manual opening.

2.This problem does exist in some WinXP systems.

3.Tried a method and solved this problem for me many times, you can try:

4.Set a password for your current user (if you already have a password), so that you need to enter the password to enter the system when you turn on the computer. It is at this time, when the boot reaches the welcome screen where you need to enter the password, do not enter the password to enter the system, but manually open the keypad, and then choose to turn off the system and restart.

5.Generally, at this time, the keypad will be automatically turned on after turning on the computer.

1.Press del to enter the BIOS at boot and set the Boot Up Numlock Status to Enable. in the BIOS Features Setup optionDifferent motherboards are slightly different.

2.In [Start] --Run] --Type [regedit]--hkey users] --default] --control panel] --keyboard] -- change the value of the value of the value name [initialkeyboardindicators] to 2

No problem, set up problem,

There are three lights on the keyboard, and as long as the leftmost light is on, it is normal. It doesn't matter if the other lights are on or not.

Every time you use it, just press num lock, it's no big problem.

If the keyboard light only turns on once and then goes out, it may be due to a problem with the keyboard light settings or a malfunction of the keyboard itself. Here are some workarounds for reference:

1.Open the keyboard settings and check whether the various light settings are normal, such as whether the settings will automatically turn off after idle time, etc. You need to change the setting to always-on.

2.If changing the settings doesn't improve the problem, you can try connecting the keyboard to another computer or laptop to test if the keyboard is working. If the keyboard is working fine on another computer, the keyboard light circuit may be damaged and the keyboard needs to be replaced.

3.If you have the same problem with the keyboard connected to another computer, it could be a hardware failure of the keyboard itself. You can consider taking the keyboard apart, check whether there are loose, rusted, damaged circuits inside the keyboard, etc., and if so, you need to repair or replace the relevant parts.

It should be noted that keyboard disassembly and repair need to be very careful, try to seek professional assistance to operate, in order to avoid more damage to the keyboard due to misoperation.

The problem of the keyboard light going off as soon as it turns on can be caused by a variety of reasons, here are some common reasons and corresponding solutions::

1.Power issue: It could be a low battery or an abnormal charger. You can replace the battery or charger and try again.

2.Software issue: It may be that the software to which the keyboard light belongs is abnormal. You can try reinstalling the software driver that adjusts the keyboard light.

3.Operating system problem: The operating system may be abnormal, and it is recommended to perform system inspection and maintenance.

4.Key problems: It may be that the keyboard is in poor contact, causing the keyboard to malfunction. You can try disassembling the keyboard, cleaning the inside of the keyboard, and checking that the keys are pressed properly.

5.Hardware issues: It may be a hardware failure of the keyboard light that needs to be repaired or replaced.

To sum up, it is recommended that you check whether the power supply and software drivers are working first, then check if the keyboard keys are working properly, and finally consider whether the hardware needs to be repaired or replaced. If the above methods cannot solve the problem, it is recommended that you contact the after-sales service center or professional and technical personnel in time for more detailed and professional help and guidance.

The laptop boots on the black screen but the keyboard light is on, I think the reasons for the failure are as follows:

1. When the computer is in sleep mode, the computer will run in a low-power state, and the display screen will be turned off at this time. If you need to wake up, you can press the power button or the space bar of the keyboard;

2. The computer should have a bug in the system that causes fake death or crash, and the computer is still running at this time, and the display screen has no content. You can force the shutdown and press F8 to enter the advanced boot mode after restarting, and select the [Last Correct Configuration] option to enter the system.

3. Eliminate whether the power supply or battery is energized, if possible, use a multimeter to check whether the rated voltage is reached, so as to eliminate the fault of the adapter. Then see if the battery is dead.

4. Then look at whether the cable of the display is in poor contact, generally the display screen does not respond at all after plugging in the power supply normally, such a situation generally requires strong hands-on ability and a professional toolbox, if it cannot be repaired by itself, it is recommended that the computer store solve it.

5. If the graphics card or memory is not in good contact, generally try to remove the graphics card or memory module, wipe the metal place with an eraser, and then plug it back in, which can generally be solved.

6. Eliminate the above reasons, it is likely that the display screen is broken, you can try to close your ears to the edge of the screen after turning on and listen carefully, whether there is a sizzling sound, and then it is silent, which is roughly the problem of the high-voltage circuit board, if it has been silent, it may be a lamp problem.
