PERIDUO-802 won’t type after computer restart, what shall I do?

1. Check Battery: PERIDUO-802 relies on batteries for power. An insufficient battery charge can lead to it not functioning correctly. To check the battery, ensure the batteries are inserted correctly, matching the positive and negative ends with the markings inside the battery compartment. If the batteries are rechargeable, charge them fully before use. If they are disposable, try replacing them with fresh ones to see if this resolves the issue. Some keyboards have battery indicators or software that shows the current battery level. Check these to ensure the batteries are adequately charged.

2. Test on Another Computer: To identify the problem, try connecting the PERIDUO-802 to another computer. This step is crucial as it helps isolate the issue. If the keyboard works fine on another system or computer, the problem might be with your original computer's hardware or software configurations. However, if it doesn't work on any computer, the keyboard itself might be faulty.

3. Direct Connection to Computer Ports: Often, issues with USB devices can stem from unstable connections, especially when using USB hubs or extension cables. Disconnect the PERIDUO-802 from any USB hubs or extension cables. Connect it directly to one of your computer's USB ports. Preferably, use a USB port on the back of a desktop computer, as these ports are directly connected to the motherboard and usually provide a more stable connection than front-side ports or ports on laptops.

4. Check and Update Drivers: Remove any previously installed keyboard drivers, then restart your computer. This can resolve conflicts between the keyboard software and your system. For this process, go to device manager and check the driver in Keyboards

Select “Scan for hardware changes. This will allow your operating system to refresh the new hardware for plug and play.

After refreshing the hardware list, please select “Update driver’ to check the any updates.

Select the option “Search automatically for driver” check driver to update or reinstall for your operating system. After your operating system confirms to reinstall the driver, your device's driver is reinstalled and ready to use.

5. Contact Customer Support: If, after following all the above steps, your PERIDUO-802 still doesn't work, it's time to seek further assistance. Reach out to for personalized troubleshooting and potential repair or replacement options. Visit the official website and navigate to the support section to find contact information or a support request form. Provide a detailed description of the issue and the steps you've already taken to try to resolve it.

How to clean a Key on the keyboard?

Unplug or turn off the keyboard.
Identify the key causing the issue (e.g., the 'Y' key), then gently pry up the key using a small, flat instrument (flat-head screwdriver) or your nail. Insert the tool or your nail under the edge of the keycap and carefully lift it up. Be gentle to avoid damaging the keycap or the switch.
Use the swab to clean any sticky areas on and around the key switch. Make sure to clean the underside of the keycap as well. If there is visible debris, use a dry cotton swab or compressed air to remove it before using the alcohol.
Reinsert the key back into its original place by gently pressing it down until it snaps back into place.
Check the keys to see if the issue is resolved.

What shall I do if the PERIDUO-802 Mouse is scrolling involuntarily?

1. check the battery: As product is wireless, like all battery-operated devices, their performance hinges on the power available from their batteries. To ensure your wireless mouse continues to operate at its best, you need to check and change or charge appropriately and timely.

2. Test on Another Computer: Start by connecting the mouse to a different computer. If the issue recurs, the mouse may be defective. In this case if you are an Amazon customer, please return the product to Amazon for a replacement or refund. If you bought the product from our official website, please contact our customer service:

3. Ensure a Direct Connection: Verify that the mouse is directly connected to one of the computer's USB ports rather than through an extension hub or dock. Using extension hubs can lead to connectivity issues which might cause erratic behavior such as involuntary scrolling.

4. Check and Update Drivers: Remove any previously installed mouse drivers, then restart your computer. This can resolve conflicts between the mouse software and your system. For this process, go to device manager and check the driver in Mice and other pointing device

Why is my mouse cursor behaving erratically, and how can I fix it?

1. check the battery: As product is wireless, like all battery-operated devices, their performance hinges on the power available from their batteries. To ensure your wireless mouse continues to operate at its best, you need to check and change or charge appropriately and timely

2. Adjust Cursor Speed and Sensitivity: Access the mouse settings on your computer (usually found in the Control Panel on Windows or System Preferences on macOS) and adjust the cursor speed or sensitivity. Reducing these settings can often help manage erratic cursor movements.

3. Use an Optimal Surface: Optical and laser mice can behave unpredictably on reflective or transparent surfaces. Use the mouse on a mouse pad or a piece of non-reflective, colored paper. This provides a consistent surface for the optical sensor, enhancing its accuracy and preventing erratic behavior.

4. Check and Update Drivers: Remove any previously installed mouse drivers, then restart your computer. This can resolve conflicts between the mouse software and your system. For this process, go to device manager and check the driver in Mice and other pointing device

Select the option “Search automatically for driver” check driver to update or reinstall for your operating system. After your operating system confirms to reinstall the driver, your device's driver is reinstalled and ready to use.

5. Restart and Reconnect: Sometimes, simply restarting your computer can resolve underlying issues causing erratic mouse behavior. After restarting, disconnect the mouse and then reconnect it. Try using a different USB port, especially if you're using a USB mouse, to rule out port-related issues.

6. Update or Reinstall Mouse Drivers: Outdated or corrupted mouse drivers can cause erratic cursor movements. Check the manufacturer's website for the latest driver software for your mouse and update accordingly. If issues persist, try uninstalling and then reinstalling the mouse drivers.

7. Check for Interference (for Wireless Mice): Wireless mice can experience interference from other wireless devices. Ensure there are no strong wireless signals near your mouse or USB receiver. Changing the USB port for the receiver can sometimes help, as can moving other wireless devices further away.

8. Inspect the Mouse for Physical Damage: Look for signs of wear or damage, such as a frayed cable, dirt or debris blocking the sensor, or damaged buttons. Cleaning the mouse, particularly around the sensor, using a soft, dry cloth can sometimes resolve issues.

9. Try Another Mouse: If possible, use a different mouse with your computer. If the problem persists with a new mouse, the issue might be with your computer. If the new mouse works fine, your original mouse may be defective.

If the issue recurs, the mouse may be defective. In this case if you are an Amazon customer, please return the product to Amazon for a replacement or refund. If you bought the product from our official website, please contact our customer service:
