罗技(Logitech)是世界上最受欢迎的电脑外设制造商之一，数以百万计的鼠标连接到世界各地的电脑。因此，许多人不时
遇到罗技(Logitech)鼠标问题也就不足为奇了。
通常，这些故障很少见且易于解决。只需(Just)按照下面的故障排除提示进行操作，您很快就会解决问题。
在没有鼠标的情况下使用Windows或 macOS(Windows)
如果您只有一个（目前坏掉的）鼠标而没有触摸板，您在操作计算机时可能会遇到一些问题，因此下面建议的一些修复可能很难实现。
在Microsoft Windows 10或 11 中，您可以使用键盘上的“开始(Start)”按钮打开“开始”菜单(Start Menu)并搜索几乎所有程序或设置。在对话框中，您可以使用Tab键在部分之间移动光标，使用箭头键在按钮之间移动，使用Enter键选择选项或按下按钮。
如果您需要随时右键单击，请查看我们的指南，了解如何在 Windows 和 macOS 中使用键盘右键单击(how to right-click with the keyboard in Windows and macOS)。
如果您是 macOS 用户，这里有一些方便的键盘快捷键可以帮助您在没有鼠标的情况下绕过操作系统：
- 要切换到菜单(Menu)栏，请按Ctrl + F2 OR Ctrl + Fn + F2（取决于您的功能键模式），然后按Enter打开Apple 菜单(Apple Menu)。
- 突出显示菜单时，使用箭头键导航菜单。
- 要切换到Dock ，请按Ctrl + F3 OR Ctrl + Fn + F3（取决于您的功能键模式）。
现在您应该可以在没有工作鼠标的情况下使用 Windows 或 macOS 计算机。虽然您可能在使用鼠标时遇到困难，但您还应该查看如何在Windows和Mac上激活屏幕键盘，以防万一。
1.检查电池
如果您使用的是无线鼠标，则应首先检查电池电量。如果您使用的鼠标使用一次性电池，请尝试更换新电池。如果您有可充电型号，请将其插入充电器并在充满后重试。
一些罗技(Logitech)无线鼠标可以通过USB数据线直接连接使用，或者在充电时继续无线工作。如果您有这些鼠标之一，那么您可以立即排除电源问题是鼠标不工作的原因。
2. 您是否连接到正确的设备(Right Device)？
某些罗技(Logitech)鼠标可让您保存多个设备的连接预设。例如，您可以通过按切换按钮在Mac、PC、Android设备和 iPad 之间切换。(Android)检查您的鼠标是否有这样的按钮。如果您不小心按下了它，它会切换到不同的配置文件。
3.使用不同的USB接口
每个计算机用户最终都会遇到一个特定USB设备在一个USB端口而不是另一个 USB 端口上工作的谜团。万一这个莫名其妙的谜题再次出现，请将鼠标或其无线接收器插入不同的端口，看看是否有任何不同。
4.在另一台计算机(Computer)上试用鼠标(Mouse)
要排除计算机问题，请在另一台支持鼠标的计算机或设备上试用您的鼠标。如果鼠标在其他设备上正常工作，但在您的计算机上不能正常工作，则表明问题出在计算机上，而不是鼠标或其USB接收器。
5. 在Unifying Receiver和蓝牙之间切换(Bluetooth)
许多罗技(Logitech)外围设备都使用该公司的 Unifying Receiver技术。任何支持统一接收器的设备都可以连接到任何统一接收器。此外，每个统一接收器可以同时连接多个设备。因此，举例来说，如果您购买鼠标和键盘，每个都有自己的统一接收器，则您只需要使用一个接收器，而不是两个。
一些罗技(Logitech)鼠标同时支持蓝牙(Bluetooth)和统一接收器。如果您有这样的鼠标，请尝试从一种连接类型切换到另一种连接类型。如果您使用的是蓝牙(Bluetooth)，请切换到Unifying Receiver，反之亦然。在这两者中，Unifying Receiver是最可靠的。
如果您有多个 Unifying Receiver，您可以尝试将鼠标绑定到另一个，以排除接收器出现故障。为此，您需要安装 Logitech 的Unifying Software以将您的鼠标绑定到随附接收器以外的任何接收器。只需(Simply)按照应用程序中的说明绑定您的鼠标即可。
就像插入新接收器一样简单，关闭鼠标，在应用程序中选择“下一步”按钮并在出现提示时打开鼠标。
6.更新鼠标固件
当我们讨论Unifying Receiver的主题时，如果您在(Unifying Receiver)蓝牙(Bluetooth)模式下使用鼠标，则它无法更新其固件。花点时间如上所述不时将鼠标切换到 Unifying Receiver，以防有可用的新固件更新。
如果您的无线鼠标带有固定USB接收器且没有蓝牙(Bluetooth)，那么您必须确保安装了罗技的软件，以便能够将固件更新到最新版本。然后按照屏幕上的说明下载并运行

7. 更新您的罗技软件
说到罗技的软件，如果您的鼠标在Windows更新后开始出现问题，您可能需要更新版本的罗技软件。前往制造商的网站，为您的鼠标寻找新的软件或驱动程序下载。
8. 手动重新安装鼠标驱动程序(Your Mouse Driver)( Windows )
如果安装最新的罗技(Logitech)软件无法解决问题，您可以手动重新安装 Windows 的默认鼠标驱动程序：
- 按Windows + R，然后键入 devmgmt.msc 并按Enter以打开设备管理器(Device Manager)。
- 进入Device Manager后，展开Mice and Other Pointing Devices部分。
- 找到您的鼠标（如果您有多个鼠标），然后按键盘上的右键单击菜单按钮，或使用其他鼠标右键单击。
- 选择卸载设备。
- 重新启动计算机。
重新启动计算机后，Windows将自动重新安装默认鼠标驱动程序。
如果重新安装驱动程序不起作用，您应该尝试手动更新驱动程序。假设您的 Windows 安装按预期工作，这应该会自动发生。但是检查您是否使用最新的鼠标驱动程序也无妨。
- 按Windows + R，键入 devmgmt.msc，然后按Enter。
- 进入Device Manager后，展开Mice and Other Pointing Devices部分。
- 找到您的鼠标（如果您有多个鼠标），然后按键盘上的右键单击菜单按钮，或使用其他鼠标右键单击。
- 选择更新驱动程序。
- 选择(Select Search)自动搜索驱动程序。
- 重新启动计算机。
如果这个自动更新过程不起作用，你可以去制造商的网站(manufacturer’s website)并自己下载驱动程序包，然后运行安装程序来完成这个过程。
9.重置鼠标
根据您的确切型号，鼠标底部可能有一个小的重置按钮或藏在其他地方。请参阅特定型号的手册。如果它没有重置按钮并且它有可拆卸电池，取出电池并等待几分钟再放回去应该也会重置设备。
如果您使用的是蓝牙(Bluetooth)，您可能需要取消配对设备并从头开始重新配对。蓝牙(Bluetooth)会出现许多不同的问题。因此，如果您使用的是罗技蓝牙(Bluetooth Logitech)鼠标，请查看我们关于在 Mac 上重置蓝牙(resetting Bluetooth on a Mac)、修复Windows 11 中的蓝牙问题(Bluetooth problems in Windows 11)以及一般蓝牙故障排除(general Bluetooth troubleshooting)的指南。
10.确保没有信号问题
现代(Modern)无线键盘和鼠标很少有连接问题。不过，如果您在 2.4Ghz 频段有很多无线电干扰的地方工作，例如来自Wi-Fi的干扰，则鼠标信号可能会受到干扰。或者，如果接收器已插入台式计算机的背面，或者接收器与鼠标之间有金属物体，也会导致问题。如果您没有任何前面板USB端口，
USB延长线是一个很好的解决方案。(USB)
如果您有外置蓝牙(Bluetooth)天线，您可能需要移动或调整它。提供内置Wi-Fi和蓝牙功能(Bluetooth)的主板通常只有一个天线用于两者。
11. 当主鼠标指针不动时(Move)
罗技的鼠标很多，但Master Mouse是其产品线中的巅峰之作。不幸的是，这些在其他方面非常出色的老鼠有一个共同的、令人恼火的问题。
如果您发现无论您做什么，您的Master Mouse突然都不会移动指针，那么您已经成为拇指下的鼠标按钮卡住的问题的受害者。您可以尝试将其轻轻提起作为临时解决方案，但如果您的Master Mouse仍在保修期内，则应将其寄回。
如果鼠标不再在保修期内，您可以将其打开并松开固定内部板的螺丝一两圈。这似乎可以缓解这种设计缺陷带来的压力，让鼠标起死回生。
Logitech Mouse Not Working? 11 Fixes to Try
Logitech is оne of the world’s most popυlar computer periphеral makers, and millіons of their mice are connected to computers everywhere. So it’s no surprise that mаny people have issues with theіr Logitech mice from time to time.
Usually, these glitches are rare and easy to resolve. Just follow the troubleshooting tips below, and you’ll be clicking away in no time.
Using Windows or macOS Without a Mouse
If you only have one (currently broken) mouse and no touchpad, you may have some trouble navigating your computer, so some of the suggested fixes below may be tricky to pull off.
In Microsoft Windows 10 or 11, you can use the Start button on your keyboard to open the Start Menu and search for almost any program or setting. In dialogue boxes, you can use the Tab key to move the cursor between sections, the arrow keys to move between buttons, and the Enter key to select options or press buttons.
If you need to right-click at any point, take a look at our guide on how to right-click with the keyboard in Windows and macOS.
If you’re a macOS user, here are some handy keyboard shortcuts to help you get around the operating system without a mouse:
- To switch to the Menu bar, press Ctrl + F2 OR Ctrl + Fn + F2 (depending on your function key mode) and then press Enter to open the Apple Menu.
- Use the arrow keys to navigate menus when a menu is highlighted.
- To switch to the Dock press Ctrl + F3 OR Ctrl + Fn + F3 (depending on your function key mode).
Now you should be ready to use your Windows or macOS computer without a working mouse. While you may be struggling with your mouse, you should also review how to activate the on-screen keyboard on Windows and Mac, just in case.
1. Check the Batteries
If you’re using a wireless mouse, you should first check the battery level. If you’re using a mouse that uses disposable batteries, try replacing them with new batteries. If you have a rechargeable model, plug it into a charger and try again when it’s full.
Some Logitech wireless mice can be used by connecting them directly using a USB cable or will continue to work wirelessly while charging. If you have one of these mice, then you can immediately rule out power issues as the reason your mouse isn’t working.
2. Are You Connected to the Right Device?
Some Logitech mice let you save connection presets for multiple devices. For example, you can switch between your Mac, PC, Android device, and iPad by pressing a toggle button. Check if your mouse has such a button. If you’ve accidentally pressed it, it’ll switch to a different profile.
3. Use Different USB Ports
Every computer user eventually encounters the mystery of a specific USB device working on one USB port, but not another. In case this inexplicable mystery has stuck again, plug your mouse or its wireless receiver into a different port to see if it makes any difference.
4. Try the Mouse on Another Computer
To eliminate the computer as a problem, try your mouse on a different computer or device with mouse support. If the mouse works correctly on another device, but not on your computer, that suggests the problem is with the computer and not the mouse or its USB receiver.
5. Switch Between the Unifying Receiver and Bluetooth
Many Logitech peripherals use the company’s Unifying Receiver technology. Any device that supports a unifying receiver can connect to any unifying receiver. Also, each unifying receiver can connect multiple devices simultaneously. So, for example, if you buy a mouse and keyboard, each with their own unifying receiver, you only need to use one receiver, not both.
Some Logitech mice support both Bluetooth and unifying receivers. If you have such a mouse, try switching from one connection type to the other. If you’re using Bluetooth, switch to the Unifying Receiver and vice versa. Of the two, the Unifying Receiver is the most reliable.
If you have more than one Unifying Receiver, you can try binding your mouse to the other one to rule out that the receiver has become faulty. For this, you need to have Logitech’s Unifying Software installed to bind your mouse to any receiver other than the one it shipped with. Simply follow the instructions in the app to bind your mouse.
It’s as simple as plugging in the new receiver, switching off the mouse, selecting the “Next” button in the app and turning on the mouse when prompted.
6. Update the Mouse Firmware
While we’re on the topic of the Unifying Receiver, if you’re using your mouse in Bluetooth mode, it can’t update its firmware. Take the time to switch your mouse to the unifying receiver as described above from time to time in case there’s a new firmware update available.
If you have a wireless mouse with a fixed USB receiver and no Bluetooth, then you must ensure that Logitech’s software is installed to enable updating firmware to the latest version. Then download the Logitech Firmware Update Tool and run it, following the instructions on-screen.
7. Update Your Logitech Software
Speaking of Logitech’s software, if your mouse has started acting up after a Windows update, you may need a newer version of Logitech’s software. Head to the manufacturers’ website and look for new software or driver downloads for your mouse.
8. Manually Reinstall Your Mouse Driver (Windows)
If installing the latest Logitech software doesn’t resolve the issue, you can manually reinstall Windows’ default mouse driver:
- Press Windows + R and then type devmgmt.msc and press Enter to open Device Manager.
- Once in Device Manager, expand the Mice and Other Pointing Devices section.
- Look for your mouse (if you have more than one) and press the right-click menu button on your keyboard, or right-click with an alternative mouse.
- Select Uninstall Device.
- Reboot your computer.
Once you’ve restarted the computer, Windows will automatically reinstall the default mouse drivers.
If reinstalling the drivers doesn’t work, you should try to update the drivers manually. Assuming your Windows installation is working as intended, this should have happened automatically. But it can’t hurt to check that you’re using the latest drivers for your mouse.
- Press Windows + R, type devmgmt.msc and press Enter.
- Once in Device Manager, expand the Mice and Other Pointing Devices section.
- Look for your mouse (if you have more than one) and press the right-click menu button on your keyboard, or right-click with an alternative mouse.
- Select Update Driver.
- Select Search automatically for drivers.
- Reboot your computer.
If this automatic update process doesn’t work, you can go to the manufacturer’s website and download the driver package yourself, then run the installer to complete the process.
9. Reset the Mouse
Depending on your exact model, there may be a small reset button on the bottom of the mouse or tucked away somewhere else. Refer to the manual for your specific model. If it doesn’t have a reset button and it has removable batteries, taking the batteries out and waiting a few minutes before putting them back should reset the device too.
If you’re using Bluetooth, you may want to unpair the device and pair it again from scratch. Bluetooth can present many different issues. So if you’re using a Bluetooth Logitech mouse, check out our guides on resetting Bluetooth on a Mac, fixing Bluetooth problems in Windows 11, and general Bluetooth troubleshooting.
10. Ensure There’s No Signal Issue
Modern wireless keyboards and mice rarely have connection issues. Still, if you’re working somewhere with lots of radio interference in the 2.4Ghz band, such as from Wi-Fi, there’s a chance the mouse’s signal is being jammed. Alternatively, if the receiver has been plugged into the back of a desktop computer or otherwise has metal objects between it and the mouse, that can also cause problems. A USB extension cable is a good solution if you don’t have any front-panel USB ports.
If you have an external Bluetooth antenna, you may need to move or adjust it. Motherboards that offer built-in Wi-Fi and Bluetooth often have a single antenna for both.
11. When a Master Mouse Pointer Won’t Move
Logitech has many mice, but its Master Mouse is the pinnacle of its product line. Unfortunately, these otherwise brilliant mice have a common and irritating issue.
If you find that your Master Mouse suddenly won’t move the pointer no matter what you do, then you’ve fallen victim to an issue where the mouse button under your thumb has become stuck down. You can try to gently lift it out as a temporary solution, but if your Master Mouse is still under warranty you should send it back.
If the mouse is no longer under warranty, you can open it up and loosen the screw holding that plate internally by a turn or two. This seems to relieve the pressure caused by this design flaw and will bring the mouse back to life.
