Hi Skirby,
Thank you for your feedback. It's greatly appreciated. Sorry for any inconvenience. Use compressed air to remove any loose debris and dust between the keys. To clean the keys, use water to lightly moisten a soft, lint-free cloth and gently wipe down the keys. If you need further assistance, please contact Logitech support on the website.

Hi, Alberta, Thank you for your seemingly rave review and love for Logitech products.

Hello GomezClan. Thank you for taking the time to write a review of the MK540 at Best Buy. I'm sorry to hear that you are having issues with the mouse not connecting and the keys sticking. Unfortunately lemons can happen sometimes with the thousands of products that get shipped out everyday. If you are still within the exchange period, please try a new one and see if that one works. If not, please contact our Customer Support and get a warranty replacement started. https://support.logi.com/hc/en-us/

Hi Anon, thank you for your feedback! The MK540 uses a wireless USB receiver which will work for both the mouse and the keyboard. You may prefer the upgraded MK850, which includes Bluetooth, Multi-device, and FLOW with Logitech Options software: https://www.bestbuy.com/site/logitech-mk850-performance-wireless-keyboard-and-optical-mouse-black/5761911.p?skuId=5761911 - Will, Logitech.

Very sorry to hear about your troubles with the MK540 and the connection issues it's giving you. Try downloading Logitech's Option software which you can use to customize settings and also insure that your unifying receiver is working properly running the latest driver. Here's a link specifically for your MK540: https://support.logi.com/hc/en-us/articles/360024850313--Downloads-MK540-ADVANCED-Wireless-Keyboard-and-Mouse-Combo . Hope this was a help. Thanks for being a Logitech customer.

Hello customer, I'm sorry to hear that you're having some issues with your MK540. It sounds like you're having some connectivity issues. My recommendation would be to try different usb ports for the unifying receiver, specifically ports that are closest to the mouse and keyboard and that have minimal obstructions.

Hi Bruce,
Thank you for your feedback. Sorry you are having issues with your keyboard. Here are possible solutions:
If your keyboard is not working, the problem is likely to be a lost connection. The connection between the keyboard and the USB receiver can be lost for several reasons. Make sure you have fresh batteries in your keyboard. Make sure your keyboard is turned on. Make sure the USB receiver is securely plugged directly into a working USB port on your computer. Turn your computer on download the correct version of Logitech SetPoint Mouse and Keyboard Software.
If you need further assistance, please contact Logitech Support on the website.
