Windows 11 25H2 – Left mouse click intermittently stops working while cursor movement still works

Question

Windows 11 25H2 – Left mouse click intermittently stops working while cursor movement still works

Luis Enrique 5

Hello,

I am experiencing an intermittent input problem on a Lenovo LOQ 15ARP9 laptop.

System information:

Laptop: Lenovo LOQ 15ARP9
Machine Type: 83JC
Operating system: Windows 11 Home Single Language
Windows version: 25H2
OS build: 26200.9168
Windows Update: fully up to date
BIOS: PQCN30WW

Problem:

At random times, the left mouse click stops responding, while cursor movement continues to work normally.

The problem is not limited to the laptop's touchpad.

When the problem occurs:

The touchpad cursor still moves normally.
The left click on the touchpad does not work.
The left click on an external mouse can also stop working.
In some cases, the Windows taskbar also stops responding to left clicks.
A right-click can sometimes immediately restore left-click functionality.
The problem can disappear without restarting Windows.

This is particularly interesting because I have reproduced the issue with different pointing devices, including a mouse that does NOT use Bluetooth. Therefore, the problem does not appear to be caused exclusively by my Bluetooth mouse.

Initially I suspected Bluetooth because the problem sometimes appeared after turning off a Bluetooth mouse. However, I later reproduced the same behavior while using a different non-Bluetooth mouse, so I no longer believe the Bluetooth mouse itself is the root cause.

I also tested the following:

Disabled "Allow the computer to turn off this device to save power" for the MediaTek Bluetooth Adapter.
- The problem still occurred.
Checked the AMD I2C Controller driver:
- Version 1.2.0.126
Checked the AMD SMBus driver:
- Version 2.0.0.23
Checked the MediaTek Bluetooth Adapter:
- Driver version 25.40.2.226

These versions match the relevant drivers provided by Lenovo for this laptop.

The touchpad cursor itself continues to work when the left click is blocked, which makes a complete touchpad hardware failure seem unlikely.

The most unusual behavior is that the problem can affect both the touchpad and an external mouse at the same time, while pointer movement continues to work.

I would like to know whether this could be a Windows 11 25H2 input-stack, Shell/Explorer, HID, or driver interaction issue.

Could someone help determine which Windows component or driver I should investigate?

I would especially appreciate guidance on how to capture useful diagnostic information while the problem is actually occurring, rather than simply reinstalling drivers or replacing the mouse.

Thank you.

I'm experiencing a very similar issue using a Tecknet MS017 mouse on a Lenovo laptop with Windows 11 25H2 build 26200.9168.

When the problem begins:

The mouse pointer moves normally, but mouse clicks stop working.

When this happens, the laptop's touchpad clicks also stop working.

I can still click and drag on the desktop to create a selection box, but I cannot click desktop icons, taskbar icons, system tray icons, or other UI elements.

Sometimes the mouse allows exactly one successful click after being switched on, then clicks stop working.

Turning the mouse off restores the touchpad clicks.

Rebooting or logging out and back in completely fixes the problem until I switch the mouse back on.

Using a wired mouse the issue never appears

Troubleshooting:

Tested the mouse on another computer. It works normally.

Tested another USB mouse on the affected laptop. It works normally.

Tested a wired mouse in the same USB port. It works normally.

Reinstalled/uninstalled mouse drivers and restarted Windows.

When the issue is present, pressing Ctrl+Alt+Delete followed by Esc does not restore mouse clicks.

I checked Event Viewer but found no obvious errors.

The problem also appeared on the second Windows 11 25H2 computer after using the mouse to see if I could replicate it. After removing the mouse and connecting that computer's normal mouse, the normal mouse had the same click problem until I logged out, but then it didn't come back. This makes it appear that the Tecknet mouse receiver may be triggering a Windows input state problem rather than simply having defective hardware.

Both computers are running Windows 11 25H2, build 26200.9168.

The fact that the problem can affect another mouse, affects both the touchpad and external mouse, and is cleared by logging out or rebooting makes me suspect a Windows HID/input or Windows Shell problem, but I can't be certain.

Having the exact same problem after "2026-09 Security Update (KB5129195) (26200.9457)" update. the only thing that temporarily fixes the issue is to press cntl + alt + del. As soon as I do that mouse is acting normal. Turning off Hardware accelerated GPU scheduling didn't help, had no effect. I'm still looking for permanent fix!

Hi @Luis Enrique

Press Win + R, type in eventvwr Then Windows Logs > System, Check for any errors around the time the issue persists. You may provide me these errors.

Go to Device Manager > Expand Mice and Pointing Devices and uninstall everything in it

Then go to the Action tab and click Scan for hardware changes. Windows should automatically reinstall it.

If your mouse stops working before you can go to the action center by clicking Alt + A, then using arrow keys, select Scan for Hardware changes then enter.

If the issue persists, go to Human Interface Devices in Device manager, Uninstall 12C HID Device, your mousepad will not work after you uninstall, then press Alt + A and run Scan for Hardware changes.

Hope this helps!

Best regards,

Nanta

Hi Nanta! I have already reproduced the issue with a non-Bluetooth external mouse, so the problem affects more than the Bluetooth mouse. The cursor continues moving, but left-click stops working, sometimes even on the Windows taskbar. Right-click can restore left-click functionality.

Hi @Luis Enrique

Did you try uninstalling the HID-Compliant mouse or mouse drivers you see in device manager and scan for hardware changes after that? Windows should automatically reinstall the driver, as the driver might be corrupted.

Also what did the event log in System looks like around the time where the issue persists.

Hope to hear back from you!

Best regards,

Nanta

Hi Nanta,

Thank you for following up.

I have not yet uninstalled the HID-Compliant Mouse drivers because I wanted to check the System Event Log first and avoid changing multiple drivers at the same time.

I have also reproduced the issue using a different external mouse that does not use Bluetooth, so the problem does not appear to be specific to my Bluetooth mouse.

The symptoms are:

The cursor continues to move normally.

Left-click stops responding on the touchpad.

Left-click can also stop responding on an external non-Bluetooth mouse.

In some cases, the Windows taskbar also stops responding to left-clicks.

A right-click can sometimes immediately restore left-click functionality.

I am going to check Windows Event Viewer → Windows Logs → System and look for errors occurring at the exact time of the problem.

Before I uninstall the HID mouse devices, could you please confirm whether you recommend uninstalling only the “HID-compliant mouse” entries under “Mice and other pointing devices”, rather than the “HID-compliant touch pad” or “I2C HID Device” entries?

I want to make sure I do not remove the touchpad/I2C device unnecessarily.

I will provide the relevant System Event Viewer errors as well.

Best regards, Luis Enrique

Hi @Luis Enrique

I recommend uninstalling entries under Mice and other pointing devices first. (These drivers are generic used for external mouse). If uninstalling and reinstalling them doesn't help, likely your HID Stack (Human Interface Devices) is glitching or corrupted.

I'm looking foward to hear back from you

Best regards,

Nanta

Update on my troubleshooting

I ran several additional tests, and I think I found a fairly clear connection with the generic M103 wireless mouse.

When the M103 is powered on and its USB receiver is connected, the left click works normally.

When I turn off the M103 and disconnect its USB receiver, the problem appears: the touchpad cursor still moves, but the left click stops working.

To rule out the touchpad itself, I connected a wired Logitech mouse. Its cursor moves normally, but its left click also stops working when the problem occurs.

I tested the Logitech in a different USB port, with the same result.

The right click continues to work.

I confirmed that Windows has the primary mouse button set to Left, and “Switch primary and secondary buttons” is disabled.

In Device Manager, the I2C HID Device reports: “This device is working properly.”

I also checked Event Viewer while the problem was happening, but no new event appeared exactly when the failure occurred.

The most interesting part: when I turn the M103 back on/reconnect it, the left click starts working again.

So far, I can reproduce this sequence:

M103 ON → left click works M103 OFF/disconnected → left click stops working on both the touchpad and Logitech mouse M103 ON/reconnected → left click works again

At this point, I increasingly suspect some kind of driver, power-management issue, or Windows interaction with the HID/USB device when the generic wireless mouse is disconnected, rather than a physical problem with the touchpad itself.

If anyone has any ideas about which driver, Windows setting, or power-management option I should investigate next, I'd really appreciate the help.

Hi Luis,

Wondering if you managed to fix the issue.

I believe I might be getting the same issue as of the latest update on my desktop PC.

Some things I have tested and did not work:

Try a different mouse.

Uninstall and reinstall mouse drivers

Resetting explorer -> helps shortly but creates the same problem shortly after

Start in safe mode -> problem persists even in the boot up menu

Fresh installation of Windows on cleanly formatted disk

Mouse is completely functional in BIOS/UEFI menu

Strongly suspecting this is a Windows update problem to do with the new explorer UI. Noticed the old UI often works for longer, but ultimately also fails.

Hi T,

Thanks for sharing your experience. I’m currently investigating a very similar issue on a Lenovo LOQ 15ARP9 running Windows 11 25H2 (OS build 26200.9168).

In my case, the cursor continues to move normally, but the left-click stops responding on the touchpad. The issue has been associated with turning off a Bluetooth mouse, and I have also reproduced the left-click issue while using an external mouse, although I am currently testing with a Logitech wired USB mouse to determine whether the problem also occurs with a wired mouse.

Another symptom I have observed is that, during one occurrence, some Windows UI elements, including the taskbar, stopped responding to left-clicks. A right-click can sometimes restore the left-click functionality.

Microsoft Q&A has suggested checking Event Viewer and reinstalling the HID/mouse devices. Lenovo Community has also suggested investigating the HID/touchpad drivers, chipset/Serial IO and BIOS.

Your report is particularly interesting because you mention that you experienced the problem even after reinstalling Windows and that it persisted in Safe Mode. That would make a Windows/input-stack issue worth investigating.

Could you let me know which exact Windows 11 version/build and update you were running when the problem started? If you know which update preceded the issue, that would be especially useful.

Also, if you find any additional information about the issue, please share it here.

Regards, Luis

In case you did not fix it yet. Turning off Hardware accelerated GPU scheduling managed to make my problems disappear. Don't know why this feature exists.
