Even something as simple as a mouse button can fail. If the left mouse button is blocked, does not respond steadily, or accidentally double-clicks, this often indicates a hardware problem with the mouse. It could be a software problem, though.
It is probably a material problem; Here's how to check
In our experience, most mouse left (or right-click) problems indicate a hardware failure. If the left click button of the mouse does not work, sometimes only responds occasionally, "accidentally" unchecking when you drag, click or double-click when you click once, it's a very good sign that there is something wrong with the hardware left-click on the button itself.
There is an easy way to check if you have a hardware or software problem: unplug your mouse from your current computer, plug it into another computer, and test the left mouse button. If you have a wireless mouse, plug it in RF Dongle in another computer or pair it via Bluetooth with another computer.
If the problem is the same when the mouse is connected to another computer, you know that you have a hardware problem. If the mouse works perfectly on another computer, there is a problem of software configuration with your current computer.
You can also try to connect another mouse to your current PC. Does he have the same problem? Otherwise, there is probably a hardware problem. If both mice have the same strange left-click problems, there is definitely a software problem with your PC.
There may also be a problem with a USB port on your system: if it is a wired mouse, try connecting it to another USB port. If you have a wireless mouse with a USB dongle, move the dongle to another USB port.
Do not forget that some problems can be irregular or intermittent, especially if the hardware is just starting to fail. The mouse button can work a good deal of time and only occasionally fails. Use the mouse with another computer long enough to check that it is working properly.
How to fix a broken mouse button
All mouse buttons will fail if you use them enough. Mouse buttons are ranked for a number of clicks. For example, the latest version of the famous Razer software DeathAdder Elite Gaming Mouse is rated for "up to 50 million clicks". A cheaper mouse can be evaluated for a lot less clicks. After that, the physical mechanism of the mouse button will wear out and stop working properly.
If your mouse is still under warranty, we recommend that you contact the manufacturer and take advantage of it. The company must repair the mouse for you or, more likely, send you a new one.
If your mouse is out of warranty, well, maybe it's time to buy a new mouse. Or, if you are ready to get your hands dirty, you can try to fix it yourself. The exact process will vary depending on your mouse model and what is broken. For example, iFixit offers a general guide on fix the mouse buttons. YouTube is full of tips for individual mouse templates, such as this guide retension a spring in a Logitech Performance MX mouse. The problem may be simpler than it seems – you may need to simply open the mouse and clean the dusts that are there. We recommend that you search for the model name of your mouse and its "fixed left click", "fixed button", or a similar search for custom information.
How to troubleshoot left-click software issues
If your mouse works perfectly on another PC but does not work properly on yours, congratulations! You can solve the problem. You just need to know what software problem you have.
Before you start, if you're having trouble following these tips because of mouse click issues, you can activate the mouse buttons by pressing Left + Shift + Left. You can then control the cursor of your mouse from your keyboard.
On Windows, it is possible to swap left and right mouse buttons. If you did this, the left mouse button may not seem to work normally – it works like the right button, while the right button works like the left button. This is for left-handed users using a straight mouse.
In Windows 10, go to Settings> Devices> Mouse. Under "Select your main button", make sure the option is set to "Left". In Windows 7, go to Control Panel> Hardware and Sound> Mouse and make sure that "Toggle Main and Secondary Buttons" is not checked.
the ClickLock function can also cause strange problems. When this option is enabled, you can briefly press and release the mouse button. Windows will view the mouse button as held down until you click again. This can help you to highlight and drag the cursor if you have difficulty holding down the mouse button, but this is a strange and confusing behavior if this setting was inadvertently activated and you are not aware of it.
In Windows 10 and 7, go to Control Panel> Hardware and Sound> Mouse. Make sure that the option "Enable ClickLock" is deselected here.
It is possible that a hardware driver problem also causes mouse button click recognition problems. We have never seen this problem in the wild, but it is worth checking out. To test this, open the Device Manager. You can do this by right-clicking the Windows 10 Start button and selecting "Device Manager".
Expand the "Mouse and other pointing devices" section, locate your mouse, right-click on it, and select "Update Driver". Click "Automatically search for updated driver software". Windows will then try to find new drivers that match the mouse.
If you see multiple mice, repeat the process for each one.
Many other websites offer a wide variety of troubleshooting tips that we doubt will be useful. As always, it's a good idea to restart your PC and see if that solves the problem. And, of course, you can try starting in Safe mode to see if there is a strange hardware problem. But scan your system files for corruption probably will not help.
Let's face it: most left-click problems with mice are due to hardware failure. Unless you have accidentally activated a particular parameter in Windows, the real solution to a left click problem is usually to replace (or repair) the mouse itself.
