Hello customer, I'm sorry to hear that you're having some issues with your MK540 wireless mouse and keyboard. It certainly sounds like you're having connectivity issues. I would recommend changing the usb port that the dongle is plugged into to something closer to the mouse and keyboard, and minimizing any obstructions in between the devices and the receiver.

Hey there Craig, I'm so sorry about that. Thank you for pointing out the issue on the site, we'll make sure to correct it. I hope you consider going with Logitech in the future. -Weston from Logitech

That's unfortunate! Refer the mentioned steps and check if that helps to resolve the issue: 1. Verify the product or receiver is connected directly to the computer and not to a hub, extender, switch or something similar. 2. Move the device closer to the USB receiver. If your receiver is in the back of your computer, it may help to relocate the receiver to a front port. In some cases the receiver signal gets blocked by the computer case, causing a delay. 3. Keep other electrical wireless devices away from the USB receiver to avoid interference. 4. Try on a different computer. Incase if the issue still persists, reach out to Logitech Support Team.

Hi eddy123, thank you for your feedback! The MK540 uses a wireless USB dongle, instead of Bluetooth. Simply plug it in and turn it on to use your new keyboard. "Logitech Options" is an advanced software, free to download but it is not required. For support, please refer to: https://support.logi.com/hc/en-us/articles/360023459773 - Will, Logitech.

Hi Berkshire, thank you for sharing your experience with the MK540. I'm sorry that you were unable to locate the Unifying receiver. The Unifying receiver would have been located in the cardboard box next to the mouse and keyboard. If you no longer have the packaging you can purchase a Unifying receiver separately and program it to work with your MK540 (https://www.bestbuy.com/site/logitech-usb-unifying-receiver/6201006.p?skuId=6201006). I'm sorry that Best Buy support was unable to assist with this issue over the phone. You might be able to go to the store you purchased it at and ask for assistance in store. Thank you for being a Logitech customer. Kristi from Logitech

Hi SimonWM, I'm sorry that the battery on the mouse died with in a year. Logitech does state that it can work up to 18 months depending on usage of the device. It is easy to switch the single AA battery that it runs on. The MK 540 also has a 1 year limited warranty through Logitech. You can visit us at support.logi.com to learn more about the warranty and your product. Thank you for being a loyal Logitech customer. Kristi from Logitech
