Note that the K580 is compatible with the following operating systems:

  • ChromeOS
  • Google Pixelbook Go
  • Android 5.0 or later

The K580 is not compatible with Windows, MacOS, iOS or Linux. It will work with Windows, however some keys are missing.

Basic Checks

If this is the first time you’re using the K580 ensure that you have pulled the battery tab out of the keyboard.

If you have been using the keyboard for a while (longer than 24 months), check the 2 x AAA batteries in the K580 and ensure that they are working. If not, replace them. Make sure that when you replace the batteries they are in the correct orientation.

This keyboard doesn’t have any exterior LEDs or other indicator for battery level.

The only way to really check battery level is to use a multimeter to measure the voltage across the terminals. Ensure that both batteries are within the acceptable voltage range. If even one of them is not within range, replace them both.

If you don’t have a multimeter, it’s easiest to just try a new set of batteries.

Wireless Connection

The K580 is a wireless keyboard. If it isn’t connecting or connects inconsistently, the problem is most likely due to a faulty wireless link.

Wireless Pairing Options

The K580 is unique in that it supports both 2.4 GHz wireless and Bluetooth connectivity. BT connectivity is important for phones and tablets where it can be difficult to find a USB port for the unifying dongle.

The K580 can also use a Unifying Receiver Dongle that is plugged into a USB port on your laptop / PC to connect.

USB Receiver

The link between the keyboard and the receiver can either stop working or work intermittently for a few different reasons. Let’s get into the details.

Low battery level

The K580 uses two (2) AAA batteries. The battery life is stated to be 24 months. It could be shorter depending on how often it has been used. The battery powers the wireless link so if there’s an issue with it, the link won’t function properly. Try using a new set of batteries to eliminate this possibility.

Wireless Connectivity

If you’re having issues with wireless connectivity using Bluetooth, switch to using the Unifying dongle and see if that makes a difference. Alternatively if you’re having issues with the receiver, switch to Bluetooth.

Using the wrong type of receiver

Sometimes when the USB dongle is lost, a user might plug in another USB dongle they have around the house. Logitech makes four different types of wireless dongles. A Lightspeed keyboard needs a Lightspeed dongle to operate – it cannot be used with a nano receiver dongle, for instance.

In this particular case, a Unifying Receiver is required and the K580 will not work with any other type of receiver.

Moving the receiver from one USB port to another

If the USB dongle is switched to another port you might lose connectivity if the port is not working. Move the receiver to other USB ports to see if it works. If you were plugged into a USB 3.0 port, try switching to a USB 2.0 port.

You can tell a USB 3.0 port by the blue color.

Using the receiver in a USB hub

USB hubs can cause the keyboard to experience latency, jitter or be completely non-functional. Instead plug the dongle directly to the PC.

Moving the receiver to another computer

If you moved your receiver dongle to another computer, the keyboard won’t work with any other computer other than the one that the receiver is plugged into.

Radio Frequency (RF) Wireless Interference

Wireless signals from Wi-Fi routers, cell phones and other sources can disrupt the link between the keyboard and PC. If an access point is placed on the same desk as the PC for instance, the wireless signals from the AP will interfere with the operation of the keyboard.

To solve this problem, move all other wireless devices away from the keyboard. Ideally at least a foot away (if not more).

If after trying all of the above steps, the keyboard is still having connectivity issues then there’s possibly an issue with the drivers. Try the next step.


In this post we have described the steps used to solve the problem of the K580 not working. There are two main categories of problems we have identified as being the cause of the problem: Battery level and Connectivity.

Within each of these categories we have provided solutions.
