The desktop mouse is red and the light is on, but the mouse is not good to make What s going on

First, the mouse is broken! Let's get a new one! Second, the hardware is not in good contact, and the plug is stronger! Third, if you know how to repair, you can see if the small bulb is in a normal position after disassembly, and you can adjust it!

The mouse light is on does not mean that the mouse is easy to use!! It's good to plug it in and plug it in again, maybe there is a problem with the host or mouse interface, try a good mouse.

Fake your mouse. Some systems do not support hot swapping of mice and keyboards.

It may be a problem with the mouse, but it is not ruled out that it is a problem with the mouse driver, you first find a universal driver from the Internet, install a new driver, and try it, if it still doesn't work, then it must be the reason for the mouse.

It is a common problem that the computer does not respond when it is turned on, and some users have no signal on the monitor when they start the computer, and the keyboard and mouse lights are not lit, and repeated restarts are to no avail. The hardware that has an impact on the boot is mainly the memory module, which is very easy to loosen, and if the gold finger is oxidized, it will cause the machine to not be turned on. Here, the system city teaches you the solution to the problem that the computer boot display has no signal, and the keyboard and mouse light do not light up.

1. Loose running memory or gold finger oxidation.

If the computer memory module is loose, it will cause the computer to fail to boot normally, which is more likely to happen, so it is recommended to try it first. We turn on the host computer, open the side panel of the chassis and pull out the memory module, and then reinstall the memory into the memory slot, if not, it is recommended to replace the memory into other memory slots, and then try to boot it to test. If you have friends with multiple memory, you might as well insert one memory first, and the other memory will not be inserted first, try to boot the test, if not, change to another memory insertion, and this memory is not inserted, alternate testing, it is not excluded that one memory is damaged, or one of the memory is loose.

2. Discharge the motherboard button battery.

The discharge of the button battery is very simple, there will be a button battery on the motherboard, after the tenon of the button battery is loosened by using a hand buckle or a driver, then the CMOS battery on the motherboard will automatically pop up, then we can take it out directly by hand, place the button battery for ten seconds, and reinstall it in place, we are testing it on start.

If the computer host turns on the monitor and does not respond to no signal, but the keyboard and mouse lights are on, and we press the "numlock" key in the keypad area on the keyboard, the light will be turned off when pressed, and the light will be turned on when pressed again, indicating that the host has been operating normally, then it may be that the monitor and the host ** line connection error, the specific solution is as follows.

Display wiring error is a problem often encountered by users, generally this kind of host has installed a separate graphics card, and many users have inserted the ** line of the display on the motherboard on the display interface, this is the wrong connection method, resulting in the computer can not be turned on normally, the display screen is black and there is no signal input. The user of the integrated graphics card must be correct when inserting the display interface of the motherboard, in addition, it is not excluded that the **cable is loose, or the display screen is black caused by the **wire damage.

If it doesn't work, it may also be that the graphics card is loose, or the gold finger of the graphics card is oxidized, pull out the graphics card and wipe the gold finger with an eraser or dry paper towel, and then reinstall it.

Neither the mouse nor keyboard is lit up, which generally means that the normal boot step has not been entered. The first thing you observe is whether the power supply fan will rotate, the CPU cooling fan will rotate, and the graphics card fan will not rotate. If the fan doesn't turn, it means that the system is not powered on at all, and it is estimated that it is not the power switch of the case.

1.If the monitor is powered on but no signal is displayed, turn off (if short pressing the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off the case, plug in and unplug the memory module again, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), and then turn it on after installation. 2.

If the above operations do not work, turn off the power and turn on the chassis, reinsert the graphics card, and plug in the data cable between the monitor and the graphics card. If it still doesn't work, then consider the graphics card damaged, then replace it with a new one. 3.

If the monitor is not powered on (the indicator light is not on), look at the back of the monitor, plug the power cord that connects to the monitor upwards, and check that the other end of the power cord is powered on to the outlet. 4.If the display can be displayed when connected to another monitor or the display of this machine is connected to another normal host and still cannot be displayed, the monitor is damaged and needs to be repaired.

Reply: If it is helpful to you, please give a thumbs up, thank you!

If the keyboard and mouse lights are not lit on the desktop, and the monitor is not lit, it means that the host has not started normally, check the host.

There are many reasons for the failure of the computer to turn on the black screen, such as the display is damaged, the motherboard is damaged, the graphics card is damaged, the graphics card is in poor contact, the power supply is damaged, the CPU is damaged, etc. For the treatment of the black screen of the computer, the method of eliminating and replacing is basically adopted, and the principle should be based on replacing and eliminating the most suspicious parts first.

1.Unplug the data cable connected to the monitor and the console, and turn on the power switch of the monitor separately. Generally, if the display is normal, it will display the manufacturer's information of the display or a prompt that the monitor is not connected, if it can be displayed normally, it indicates that the display is unlikely to be damaged.

2.Check that the exposure is good. Check whether the contact between the graphics card and the monitor is good, and whether the contact between the graphics card and the motherboard IO slot is good, and if necessary, remove it and reinstall it again to ensure that it is installed in place and in good contact.

3.If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound.

If the memory fault is ruled out, only the CPU and the motherboard are left.

1. In addition to excluding mouse damage and poor interface, you can know the mouse driving problem, right-click the [Computer] option on the desktop, and select [Device Manager] in the pop-up menu bar;

2. Find the mouse driver first, and then check whether it is installed, if there is a question mark, it means that there is a problem with the branch driver;

<>4. After waiting for a period of time, the scanning is completed, and the driver can be reinstalled quietly when the problem driver is found.

There are several possible reasons why the desktop mouse light is on but not responding:

Failed to connect the mouse to the computer: Check whether the interface connecting the mouse to the computer is loose or falling off, and confirm whether the connection is stable.

Mouse battery problem: If the mouse is wireless, you need to check whether the battery has been depleted or whether the battery installation is in a positive state, and if you need to replace the battery, try again after replacing it.

Mouse driver problem: Check whether there is a problem with the mouse driver resistance segment source program, you can try to reinstall or update the driver.

Mouse hardware problems: If none of the above is a problem, it may be that the mouse itself is faulty and needs to be replaced or sent for repair.

In short, if the mouse indicator lights up but cannot respond, you need to first check the mouse connection, battery, driver, etc., and then consider whether to replace the mouse or send it for repair after eliminating basic problems.
