Left or right mouse button (LMB / RMB) does not work: what to do? How to replace a mouse button with a keyboard

Good afternoon!

In general, according to statistics, it should be said that the left mouse button is one of the most loaded.

It would seem, well, what is a simple office job? But with it, LMB * is pressed up to 200 or more times per hour (on average)! In some games, the indicator can be several times higher (in general, the load on it, God forbid ...). However, there is enough work for the right one too ... 👀

In general, if any of the mouse buttons fail, work at the PC becomes very inconvenient (and in some cases even impossible).

To begin "analysis" of the situation would be worth dividing the problem into two directions: hardware and software (for example, if the button itself is broken, then this is a hardware problem, if the problem is in the driver, for example, it is a software problem). Actually, based on this, I will try to share this article ...

So, let's get down to business ... 👌

* People's abbreviation:

  • "LMB" - left mouse button;
  • "RMB" - right mouse button;

Recommendations for those who have one of the mouse buttons not working

Is there a problem with the mouse? (We diagnose!)

The very first thing I recommend doing in this case ischeckis everything okay with the mouse... Often, with heavy use, the mouse button itself stops working (and you need to press it too hard for it to react).

By the way, a characteristic symptom in this case: periodically LMB (RMB) of the mouse either does not react, then starts to work, and, often, a double click is immediately obtained.

For diagnostics: just connect the mouse to another computer / laptop (which does not have a similar problem). If it behaves similarly on it (i.e. LMB does not work), then the problem is probably in the mouse (the button may be out of order, the board is damaged, etc.).

In this case, there are two ways: either buy a new mouse, or try to repair it (if you have free time to experiment 😉).

👉 By the way!

You can buy cheap mice (and other computer hardware) in Chinese online stores.

A few words about its repair

If you have experience in soldering, you can try to disassemble the mouse, clean it from dust and see if any contacts have gone where, if everything is in order with the board.

If everything is OK, then you can try to solder a new one instead of the old button. In principle, there is nothing complicated here (unless you need old mice from which to take a working button).

By the way, you can also try to set the right button in place of the left one, and the left button to the right. This option is especially relevant in cases when your LMB does not work well (or a double click occurs).

Soldering the mouse buttons

Services, as far as I know, do not repair mice (since the wizard's time is more expensive than a new mouse). Unless you have an expensive gaming mouse (with which you have already become akin, and are ready to pay any reasonable amount for it).

What to do if the mouse itself is functional, but LMB (RMB) does not work

This is a more interesting option (ie on another PC the mouse works and everything is in order with it, but on the current one it behaves "strange" for some reason).

In general, one of the first tips would be to try restarting your computer (sometimes a similar problem occurs due to various system failures, high CPU load, etc.). If the reboot did not work, then I recommend the following ...

*

1) Try connecting the mouse to a different USB port

It is highly advisable not to connect it to the USB ports that are on the keyboard, go through some kind of splitters, etc. adapters ...

Connect it to the USB on the back of the system unit (if you have a laptop, then directly to it). In any case, check several of your USB ports in sequence.

If you have a problem with a PS / 2 mouse, connect it to the USB port via the adapter.

2) Check the power saving mode

The fact is that when it is running, the computer can turn off the mouse in order to save energy. To check if this is so, you need to open the device manager (I will give a way to do this without a mouse):

  1. press Win + R to pop up a window "Run" ;
  2. enter the devmgmt.msc command;
  3. press Enter.

IN device manager find the tab "Mice and other pointing devices" (see the screen below 👇). If the mouse does not work for you: first press "TAB" (to make the pointer appear) and then use the buttons to move up and down.↑ "," ↓ "(note: usual" arrows "on the keyboard), to expand the tab, click "→".

After selecting the desired device (for example, "HID-compatible mouse". By the way, you may have a slightly different name), just press "Enter".

Device Manager - Mice

Next (using the "TAB" and "arrows") open the "Power Management" tab and uncheck the box "Allow this device to be turned off to save power" .

Save your settings and restart your computer.

3) Check the power supply parameters

To do this, open the Windows Control Panel, and go to the following path: Control Panel \ Hardware and Sound \ Power .

Then open the settings of the current power scheme.

Power plan settings

Then follow the link "Change advanced power settings" (see the screen below 👇).

Add. power parameters

In the tab "USB Options" disable USB port disconnection (see example below 👇).

Power Supply (USB Disconnect - Prohibited)

Next, save the settings, restart your computer and check the functionality of the mouse.

4) Disable touchpad (applies to laptops)

In some cases, the parallel operation of the touchpad and the mouse is difficult (the fact is that modern touchpad operation "does not take into account" accidental clicks on it (for example, when you are typing something and accidentally hit the touchpad), i.e. it simply blocks such clicks as if they weren't there.

Note that it can also block not only them, but also your LMB / RMB clicks).

To disable the touchpad in Windows 10, just open the system settings, the tab "Devices / Touch Panel" and put it in "Off" mode. (example below 👇).

I note that many laptops have specials. keys for on / off touchpad: for example, on ASUS laptops this combination Fn + F9 (usually).

5) Check the drivers for the mouse (this especially applies to gaming mice that come with additional buttons)

According to statistics, as a rule, more problems arise with fancy mice: which have additional keys (they are often used in games for quick access to the game character).

So, for such mice, it is often necessary to install drivers manually (since the driver that Windows picks up may not work correctly with it).

Typical gaming mouse

In general, the topic of drivers is "quite" extensive. If you do not know how to update them, I recommend using the materials, links to which are below:

  1. 10 best programs for updating drivers (automatically!) - see the selection;
  2. How to find and install a driver for an unknown device - see the instructions.

6) For Windows 10 users - check that tablet mode is not enabled

The fact is that Windows 10 is a universal system, and it is installed not only on the most ordinary classic PCs and laptops, but also on tablets (and transformer devices). And, of course, it is more convenient to use the system on them in specials. "tablet mode" (and the mouse does not work in it *).

And it was noticed that in some cases it can turn on even if you do not have a touch screen (and the device is not intended for this in any way).

Therefore, if you have this OS, try clicking on Win + A (to open the side menu), then several times on TAB, and check if it is turned off. 👇

👉 How to replace the right or left mouse buttons with the keyboard

Yes, you can partially replace the mouse with a keyboard (any of the buttons). Because This question is not rare, I also included it in this article.

👉 Right

  1. option 1: the classic keyboard has call button context menu - this is RMB (usually, it is between Ctrl and Win 👇);
  2. option 2: use a combination Shift + F10 (on laptops Shift + Fn + F10 is possible);
  3. Option 3: Windows has a special. a mode in which the keyboard completely replaces the mouse. To activate it - clickALT + SHIFT + NUMLOCK (after "minus" it will become an analogue of PKM);
  4. Option 4: If you have a laptop, use the touchpad (this is obvious).

Typical keyboard - press Shift + F10

*

👉 Left

  1. option 1: key Enter replaces paintwork;
  2. option 2: combinationALT + SHIFT + NUMLOCK will put the keyboard in a special mode (replacing the mouse). The "5" key (or "forward slash") will become an analogue of LMB;
  3. option 3: laptops have touchpad (press the long left button at the bottom of it).

👉 General points:

  1. TAB and arrows (→, ↓, etc.) - help to move the cursor over various elements on the desktop (or an open program);
  2. Alt + TAB - moving between windows;
  3. Ctrl + Esc or Win - call the START menu;
  4. Win + E - call the conductor;
  5. Alt + F4 - exit from the application (close);
  6. Ctrl + S - saving the file;
  7. Ctrl + A (Ctrl + C) - select everything on the page / window (and copy to the clipboard);
  8. Ctrl + V - paste into the open document everything that was previously copied to the clipboard.
