QuestionI lost my usb “dongle” to this wireless keyboard mouse combo. Can I purchase at Best Buy the Logitech usb dongle individually?
Asked 5 years ago by Anonymous.
- Answer Hello, Best Buy does not sell the Unifying receiver on its own. You can find it on the Logitech website. You can also purchase a mouse that uses the Unifying receiver (like the M325) and use that receiver for the MK combo.

QuestionMy pc has only one USB port so will they both connect to it or do I need 2 USB ports?
Asked 7 years ago by GeniusMe707.
- Answer Both keyboard and mouse use the same fob - you only need one USB port. However, you can buy a USB hub like the one shown so you can use up to 4 USB devices at one time.
  I would recommend:
  - Targus - USB 2.0 4-Port Hub - Black

QuestionHow long does it last if you never turn it on/off? is there an indicator light to tell you its low on battery?
Asked 4 years ago by Leo.
- Answer Hello Leo. The mouse and keyboard in the MK540 use very little power and have an automatic sleep function that kicks in after not being used for a couple minutes. The keyboard can last up to 36 months on 2 AA batteries and the mouse can last up to 18 months on 1 AA battery. The battery indicator light will turn red when it is time to change the batteries.

QuestionI have a Logitech MK540 mouse & keyboard combo and lost my mouse. Can I buy a replacement mouse that will connect to my existing receiver, and what model? I don't have additional USB ports available & prefer not to use one of those multiport extensions.
Asked 1 year ago by Kex7.
- Answer Hey! The Logitech MK540 keyboard you have includes a Logitech Unifying receiver. This handy receiver allows you to connect not only your MK540 keyboard but also other compatible Logitech devices to your computer using just one receiver! Here are some Logitech mice that work with the Unifying receiver, also known as those featuring the orange unifying logo: - M705 Marathon Mouse - M720 Triathlon Mouse - M575 Wireless Trackball - MX Ergo Vertical Mouse - MX Vertical Wireless Mouse For a complete list of compatible devices, we recommend checking the official Logitech website for the MK540 or the specific mouse you're interested in. This will ensure you get a perfect match for your Unifying receiver setup.

QuestionI have Windows 10, Chrome and Firefox. Will this keyboard/mouse work while I'm in Firefox? Also, if I upgrade to Windows 11 will this work. Thx
Asked 3 years ago by mcphx.
- Answer Yes to working with Firefox, chrome, brave and windows edge/explorer - could be more but I've used all of those successfully. Additionally, I have windows 10, don't know about windows 11, but I dont see why it wouldn't work. There are no issues with it working with any program or computer. I have Dell, Microsoft and Cyber power computer brands and they are all connected to this logitech wireless keyboard and mouse. Absolutely love the switching between computers. Only downside is that if you have a slow computer, the keyboard and mouse may be slow to respond or 'stutter' in response because the connection is slower to receive and respond. I found this on my dell laptop that is older and slower.
