Looking at the motherboard model, it should be UEFI bios. First find a keyboard with PS2 port, enter the bios, turn off UEFI startup, and change it to Legacy mode. If there is fast startup, turn off options like Fast Boot. UEFI Start up, turn on fast startup, USB interface detection may be turned off before entering the system, and USB devices can be used after entering the system.
The keyboard light does not light up. It is highly likely that the memory is faulty. It may also be caused by static electricity on the motherboard or the motherboard is faulty. Use an eraser to wipe the gold finger of the memory graphics card, and remove and insert the memory several times.
The problem remains. If there is dual memory, use a single memory for testing.
The problem still persists. Re-plug the various cables inside and outside the chassis, and connect the electronic battery on the motherboard to restore the BIOS default settings. If it still doesn't work, there's basically something wrong with the hardware, so I won't force you to send it for repair.
If you are a hands-on expert, unplug the peripherals, hard disk, and independent graphics card and connect the integrated display. If it lights up, it means there is a problem with the unplugged hardware.
Also, there is a high possibility that there is a problem with the power supply and motherboard.
If the light of your computer keyboard does not light up, it may be caused by the following reasons:
1. The light is not turned on: Some computer keyboards need to turn on the light manually. Typically, you turn the lights on or off by pressing keys like Fn F4 or Fn F11.
2. Power supply problem: If the computer keyboard light does not light up, it may be caused by a power supply problem. Make sure the keyboard is connected properly and the cables are not damaged.
3. Driver problem: If your computer keyboard light does not light up, it may be because your computer lacks the correct driver. You can download and install the latest drivers from the manufacturer's website.
4. Fault: If none of the above methods work, there may be a fault with the computer keyboard. Consider replacing the keyboard or contacting the manufacturer for repair.
1. First of all, you need to understand the structure of the button. If the removed button is x, see what the structure inside is like. Align the direction of the keycap and press it against the bracket.
2. Use a little force and a click sound will appear, indicating that the installation is successful. Next, install the more complicated shift key. The two situations are slightly different. The bracket of the x key is directly connected to the keyboard, while the bracket of the shift key is connected to the keycap.
3. Now you need to remove the white bracket from the keycap. There are three parts in total, two white parts and a small steel wire. The small steel wire is connected to the inside of the keycap and does not need to be removed.
4. Combine the two white parts into one, and then install the integrated white bracket onto the keyboard. Note that there are buttons on the keyboard. Be careful when installing and remember to pull or pull hard.
The indicator light does not light up. Is the power indicator light wire connected backwards or the machine does not start at all?
