Will the wireless mouse cause a crash and automatic restart, and suddenly lose power

1. The mains voltage is unstable.

Generally, the switching power supply of home computers works in the voltage range of 170V 240V, and when the mains voltage is lower than 170V, the computer will automatically restart or shut down. Because we sometimes don't feel the fluctuation of the mains voltage, we mistakenly think that the computer will restart automatically for some reason.

Solution: For areas where the power supply is often unstable, we can purchase a UPS power supply or a wide switching power supply of 130 260V to ensure the stable operation of the computer.

2 Poor quality of the plug strip or power socket with poor contact.

Most of the power sockets on the market are of poor quality, and the internal contacts are manually soldered, and acid flux is often used, which can easily lead to the oxidation of the solder joints in the future use and cause circuit breaking or leakage between the live wire and the neutral wire. Because of manual welding, and because of the poor elasticity of the phosphorus brass sheet used, it will not take long to lose its elasticity, resulting in poor contact with the power plug of the host or display and produce a large contact resistance, and a large amount of heat will be generated during long-term work, resulting in virtual connection, which will be manifested as the host restarting or the display black screen flickering.

There is also a possibility that the wall socket used in our home, most of the wall sockets are not installed by professionals, so the wiring inside the socket is very non-standard, especially if these sockets often use high-power electric heaters, it is easy to cause internal heating and oxidation to form intermittent power failure, causing computer restart or monitor blinking.

It's hard to say, maybe it won't, and it's recommended that you switch to a wired mouse.

First, check if the touchpad function of the notebook is locked and turned off.

If you accidentally operate the computer and press the button to turn off the touchpad by mistake, you may turn off the laptop touchpad, so when the touchpad is not available, you can try to press the FN+F9 or FN+F10 or FN+F6 key combination to turn on the touchpad (different shortcuts are different for different models).

Or turn it on under the system, tap Settings --- device ---touchpad--- open.

Detect if the touchpad driver is normal.

If the above methods still can't solve the laptop touchpad failure, then you might as well reinstall the system or restore the system to factory settings to try, this is also the ultimate solution, if it still can't be solved, it is recommended to go to the official after-sales testing.

There are mainly the following situations that can lead to:

1. The mouse has a power-saving setting, and it will automatically turn off when the mouse is not operated for a period of time.

2. The mouse battery is insufficient, that is, the power is weak, and replacing the battery can be solved.

3. The defect of the design of the mouse itself, there is no solution to this situation, and the mouse can only be replaced.

Is such a wireless mouse keyboard. In order to save electricity. Reopen with a double-click of the mouse.

There are three reasons for this, please refer to the solution.

1. At present, most mainstream computers integrate more functions, such as network cards, RAID, IEEE 1394, and even Wi-Fi wireless networks.

During normal games, or in the process of running other programs, the mouse cursor suddenly disappears, the mouse operation does not work, and the network is disconnected at the same time, which is very likely to be caused by the poor heat dissipation of the Nanqiao chip. It is recommended to clean the dust inside the body, install a good heatsink on the south bridge chip of the motherboard, and re-plug the ADSL device.

2. The network card sleep guide will also cause this situation.

Workaround: Open, Start -> Settings -> Control Panel -> Network Connections -> Local Connections -> Properties -> Configuration (..)

Power Management - > will allow the computer to turn off the tick of the device.

3. The power-saving mode of the router is used to judge the Internet environment to save power, but often the program design is defective, which will also cause disconnection for no reason, so it is recommended to upgrade the routing firmware. A simple method is also to turn off the router's battery saver mode.

In the power management of the control panel, this can set how much time the computer does not respond to the monitor, how much time to manage the hard disk, how much time to standby If you are powered on, you can cancel it all

It's very obvious.

Either the power supply is insufficient.

Either there is a problem with the motherboard interface.

There is also a relatively low-level problem, the chassis hits the ground, right? If you don't have a talk, you can put the main chassis underground and try it, so there's no need to look at it.

If it is not the third type, according to my long-term maintenance experience, 95% of the time is determined that a part of the motherboard interface is virtually connected, and some programs with large memory requirements or other things are opened, resulting in the instantaneous power failure and instantaneous power supply of the virtual part of the mouse interface, which is easily cut off, unplugged and reinserted because there is action, and the interface is connected with electricity, so the virtual part will be connected together, so as to work normally.

Solution: It is best to go to the maintenance department again to confirm whether it is determined to be a motherboard interface problem, after confirmation, the first virtual interface is very simple to repair, any electrician with a small electric welding can be easily completed. It's just a few dollars to a dozen dollars.

It just so happened that when he repaired it, he opened the chassis to clean the dust for you, and saved the cleaning fee. Remember to take good care of the case in the future!
