The M350 connects to your computer through Bluetooth, which means no cable or USB receiver needed
The Logitech M350 is a wireless keyboard that uses Bluetooth to talk to your computer instead of plugging into a port. When you turn it on and put your computer in pairing mode, they find each other and stay connected. The whole process takes about five minutes and works on Windows, Mac, and Linux machines.
You will need the keyboard itself, two AA batteries (which come in the box), and a computer with Bluetooth built in. Most laptops have Bluetooth. Desktops usually do not unless you add a Bluetooth adapter — a small USB device that costs $10 to $20 and plugs into any USB port.
Key Takeaways
- The M350 uses Bluetooth to connect, so your computer must have Bluetooth capability or you need to buy a USB Bluetooth adapter.
- Insert two AA batteries into the keyboard before you start pairing, and flip the power switch to the on position.
- Put your computer in Bluetooth pairing mode, then press the connect button on the bottom of the keyboard to make them find each other.
- Once paired, the keyboard will reconnect automatically when you turn it on, as long as Bluetooth stays on.
Check whether your computer has Bluetooth
Open your computer's settings and look for Bluetooth. On Windows, go to Settings > Bluetooth & devices. On Mac, go to System Settings > Bluetooth. If you see a Bluetooth option and it can turn on, you have it built in. If there is no Bluetooth section at all, your computer does not have it.
If your computer lacks Bluetooth, you have two choices: buy a USB Bluetooth adapter (search "USB Bluetooth adapter" at any electronics retailer), or use the M350 with a USB receiver instead. The M350 does not come with a receiver, but Logitech sells one separately if you want that option.
Insert batteries and turn on the keyboard
Open the battery compartment on the back of the M350 by sliding the cover down. Insert two AA batteries with the positive end (the bump) facing up. Close the cover. Flip the power switch on the bottom of the keyboard to the on position — you will see a small light turn on.
The keyboard will stay on until you switch it off. It uses very little power, so two AA batteries typically last several months.
Put your computer in Bluetooth pairing mode
On Windows, go to Settings > Bluetooth & devices > Add device. Click "Bluetooth" in the window that opens. Your computer will start looking for nearby Bluetooth devices.
On Mac, go to System Settings > Bluetooth, then click "Pair New Device". Your Mac will start searching.
Leave this window open — your computer is now listening for the keyboard.
Press the connect button on the keyboard
Look at the bottom of the M350. You will see a small button labeled "Connect" or sometimes just a dot. Press and hold it for three seconds until you see the light on the keyboard blink. This tells the keyboard to broadcast its presence to nearby computers.
Within a few seconds, the M350 should appear in your computer's list of available devices. Click on it to complete the pairing. Your computer will confirm that the connection is successful.
Test the keyboard and adjust settings if needed
Open a text editor or web browser and type a few characters to make sure the keyboard is working. If the keys respond, the pairing is complete.
On Windows, you can now go back to Settings > Bluetooth & devices and see the M350 listed as a connected device. On Mac, it will appear in System Settings > Bluetooth. From this point on, the keyboard will reconnect automatically whenever you turn it on and your computer's Bluetooth is active.
If the keyboard does not type anything, go back to your Bluetooth settings and try removing the M350 from your list of paired devices, then repeat the pairing process from the connect button step.
What to do if pairing fails
If the keyboard does not appear in your computer's device list, first check that the power switch on the bottom is actually on — the light should be visible. Then press the connect button again and wait ten seconds before checking your computer's list.
If it still does not appear, restart your computer's Bluetooth by turning it off and back on in your settings. Then press the connect button on the keyboard again. Sometimes Bluetooth needs a fresh start to find new devices.
If you have tried this twice and the keyboard still will not pair, the batteries may be low even though the light is on. Replace them with fresh AA batteries and try once more.
Frequently Asked Questions
Do I need to pair the keyboard every time I use it?
No. Once you pair it the first time, the keyboard remembers your computer. When you turn the keyboard on, it will reconnect automatically as long as your computer's Bluetooth is on. You only pair once.
Can I use the M350 with multiple computers?
Yes, but you have to pair it separately with each computer. The keyboard can remember up to three devices. To switch between them, turn the keyboard off, then turn it back on while holding the connect button for five seconds. Your computer's Bluetooth settings will show it as a new device to pair.
What if my computer has Bluetooth but the keyboard still will not connect?
Make sure Bluetooth is actually turned on in your settings — it is straightforward to miss. Also check that no other Bluetooth devices are trying to pair at the same time, as this can confuse the connection. If you have an older computer, its Bluetooth version may not work with the M350; contact Logitech support with your computer model and they can tell you whether it is compatible.
How do I know if the keyboard is running out of battery?
The light on the keyboard will dim or blink slowly when the batteries are low. You will also notice the keys become less responsive. Replace the batteries as soon as you see this, because the keyboard will stop working once they are completely dead.
Can I use a USB cable to charge the M350 instead of batteries?
No. The M350 uses only AA batteries — there is no charging port or USB cable option. This is actually an advantage because you never have to wait for it to charge; you just swap in fresh batteries.
