First, make sure the mouse battery is in good contact and clean the battery and battery slot. If the problem persists, try replacing the battery with a new one to rule out the possibility of aging or damage to the battery.
In addition, you can check whether the receiver of the wireless mouse is well connected to the computer to avoid signal interference. If the problem is still unresolved, you can try using another battery-powered method (such as rechargeable batteries or battery boxes).
If the above methods are still ineffective, there may be a problem with the internal circuit of the wireless mouse, it is recommended to contact professional maintenance personnel for repair.
We'll have to get it repaired and don't do it yourself if the warranty isn't up. This is because of aging contacts.
