Q: QuestionI bought a combo Keyboard mouse Logitech K540 and just recently the keyboard does not work. I have troubleshooter the driver and batter but the keyboard does not work. The mouse continues to work. Could the receiver malfunction affect only keyboard?

Asked 3 years ago by ChrisG.

• A:Answer Hello ChrisG! Sorry to hear you're having issues with K540 of your MK540 Combo. Couple things to check, when flipping the On/Off switch at the top right of your keyboard, do you see a light come up right next to it? If so, that mean the battery if working fine, so maybe it's just a pairing issue. What I would suggest you to do is try downloading the Logitech Unifying Software https://support.logi.com/hc/en-us/articles/360025297913-Logitech-Unifying-Software, install it on your computer, and follow the steps to make sure the K540 is properly paired with the Unifying Receiver. If you see that it is paired with the Receiver and still isn't working, then I'd suggest getting your Combo exchanged if you're still under the store warranty, or file a warranty claim with Logitech directly if you're still within your 1 year of warranty. - Mathieu from Logitech

Q: QuestionI tried downloading new software but the Receiver will not pair with Keyboard. The Receiver recognizes the Mouse but not the Keyboard. Based on this, would replacing the Unifying Receiver make a difference in connecting to Keyboard?

Asked 3 years ago by ChrisG.

• A:Answer Hello ChrisG! If the Logitech Unifying Software is still not detecting your K540 Wireless Keyboard after following the on-screen instructions in the software, but your M320 Wireless Mouse is being detected, then the keyboard may have a different issue. I don't think replacing the Receiver would make a difference if it is being detected by the Mouse unfortunately. - Mathieu from Logitech
