Microsoft wireless mouse 1000 not functioning properly, after plugging in the wireless mouse causing CapsLock to blink On and Off

Hi,

Thank you for posting your query on Microsoft Communities.

It could be difficult when things don't work the way it should be on your computer. This issue could occur due to incompatible or corrupt/missing drivers for your wireless mouse. Let’s try to narrow down to see what exactly is causing this issue and try to fix it.      

Prior to performing any troubleshooting steps, I suggest you to try connecting the wireless mouse to a different computer and check the behavior.

Please follow the methods mentioned below:

Method 1: Follow the steps:

Step 1: Resynchronize your device with the receiver.

To resynchronize the mouse or the keyboard with the receiver, follow these steps.

Note When you synchronize the mouse or the keyboard with the receiver, put the device near the receiver and put any other wireless keyboards and mouse at least 6 feet away.

1. Press the button on the receiver, and then verify that the light on the receiver starts to blink.

Note Some newer Microsoft devices are permanently bound to their receiver and cannot be reset. If your device does not have a button, skip to Method 2. 2. If a dialog box appears on the screen in several seconds, follow the instructions that appear on the screen. Otherwise, go to the next step. 3. Press and release the Connect Channel button on the bottom of the mouse or the keyboard. 4. Check the green light on the receiver. A steady green light means the synchronization was successful. If the problem persists, try steps 1 through 4 again.

For the Wireless Notebook mouse: This issue can occur if the micro-switch on the bottom of the mouse is not released. Use a pin or a pen to try to release the button if it is depressed.

Step 2:

I suggest you to try connecting the wireless mouse to a different USB port and check.

Step 3: Reinsert the batteries or install fresh batteries.

Both the wireless keyboard and the wireless mouse rely on AA alkaline batteries for power. Remove the batteries, and then insert them again. If the problem persists, install a fresh set of batteries in the device that you are having problems with.

Step 4: Check for interference.

Items such as wireless routers, radios, cell phones, desktop fans, fluorescent lights, and large metal objects like computer cases and metal furniture may interfere with the signal of the keyboard. Try to keep such items away from the keyboard, and check the behavior of the keyboard.

Do not put the mouse or the receiver near any electrical devices, especially transmitters such as cordless or cellular telephones or other wireless mouse devices or receivers. A distance of at least 8 to 12 inches is recommended. Do not put the mouse or the receiver on metallic surfaces or objects, especially long metallic rails or cables. We recommend that you keep the mouse and the keyboard a minimum of 3 feet from metallic objects.

Method 2: Run Hardware and Device Troubleshooter.

If your computer is having problems with a recently installed device or other hardware, try using the Hardware and Devices troubleshooter to fix the problem. It checks for common issues and makes sure that any new device or hardware attached to your computer was installed correctly. Follow the steps given below:

1. Press Windows Key + W Key together.
2. Write Troubleshooting in the search box right up corner and hit enter.
3. Click on Troubleshooting tab.
4. Click on view all option on the upper left corner.
5. Select the Hardware and Deviceoptions from the list.
6. Click Next to run the Hardware and Device Troubleshooter.

Method 3:

I see that Microsoft has not provided compatible Windows 8.1 driver software for Microsoft Wireless Mouse 1000. I suggest you to uninstall the mouse driver and reinstall the drivers in compatibility mode.

Please follow the steps given below to uninstall and then reinstall the driver.

1. Press Windows key + X key when you are at desktop.
2. Select Device Manager.
3. Find and double-click Mouse Driverfrom the left panel to uninstall.
4. Right-click the device, and click Uninstall.
5. Windows will prompt you to confirm the device’s removal. Click OK to remove the driver.
6. Now go the manufacturer website of the mouse and try to install the latest drivers in compatibility mode.

To download compatible Windows 8 Wireless Mouse 1000 driver software, refer to the following link:
