How to Fix Dell Left Click Not Working Issues

The mouse left click stops working on your Dell laptop or desktop? Don’t worry. You can fix the problem by following the steps below.

The problem can be a hardware failure or a Windows problem. So firstly, we need to troubleshoot whether it’s a hardware failure or a Windows problem:

Try your mouse on another computer. If the mouse works on another computer, it’s probably a Windows problem. If the mouse doesn’t work on another computer, it’s a hardware failure. Alternatively, you can try to use another mouse on your laptop/desktop to see if it works on your laptop/desktop properly.

What to do if it’s a hardware failure

If the mouse is still in warranty, you can contact the manufacturer. The manufacturer will help you fix the broken mouse or might even give you a new one to replace.

If the mouse is out of warranty, you’ll need to fix it on your own. Fixing a broken mouse requires some technical skills. If you’re not good at it, you can ask someone who’s good at it for help, or you can take it to a computer repair store to have it fixed.

If you’ve used the mouse for a long time, maybe it’s time to buy a new mouse.
