Your mouse may not be working for a variety of reasons. First, it could be a hardware issue with the mouse itself; it may be out of batteries, damaged or otherwise malfunctioning. Additionally, there could be a problem with your computer’s settings or drivers, or there could be a compatibility issue between your mouse and the operating system.
If your mouse isn’t working, the first thing to do is to check that it’s physically connected to the computer and that it has working batteries or power. If the mouse is wired, make sure the cable is securely connected to the ports on the computer. On wireless mice, make sure the USB receiver is connected to a port on the computer and that the mouse is turned on and within range of the receiver. If your mouse runs on batteries, test them to see if they need to be replaced.
Next, see if the mouse works on another computer. This will tell you whether or not the problem is with the mouse itself. If it works on another machine, the problem lies with your computer; if it doesn’t, then the issue is with the mouse.
If the mouse does not work on another machine, it likely needs to be replaced. If the mouse does work on another machine and still doesn’t work on your own, you’ll have to troubleshoot on your computer.
Start by checking your settings. Make sure that you have the most recent version of your operating system installed as well as the latest updates for your computer’s drivers. Additionally, make sure that the mouse is selected as your default pointing device in the settings.
If all of those steps didn’t solve the problem, you may be having a compatibility issue. It’s possible that your mouse is not compatible with your operating system. Older versions of Windows and macOS may not support certain mice, or certain features of mice may not be available to older versions of software.
Finally, a third-party driver may be causing the issue. Some manufacturers create drivers specifically for their products; if you are using such a driver, uninstall it and try using the driver provided by your operating system instead.
If none of these steps solved your problem, you may need to contact a technician or the mouse manufacturer for assistance.
