Fix: Wireless Keyboard Not Working After Battery Replacement

Have you ever swapped out the batteries in your wireless keyboard, only to find it still refuses to work? It’s a frustrating situation but don’t worry; there are several steps you can take to get back to typing in no time.

This article walks you through the common issues and solutions for a wireless keyboard that won’t work after changing batteries.

Hot to Fix  Wireless Keyboard Not Working After Battery Replacement?

Here are some steps you can take to troubleshoot a wireless keyboard that’s not working after replacing the batteries:

Check the Batteries

First things first, ensure the new batteries are inserted correctly. It sounds simple, but it’s easy to mix up the positive and negative ends, especially if you’re in a hurry. If the batteries are in the right way and your keyboard still isn’t working, try a different set of batteries. Sometimes, new batteries might be dead on arrival.

Re-establish Connection

Wireless keyboards connect to your computer via a USB receiver or Bluetooth. If the keyboard isn’t working after a battery change, the connection might need to be re-established.

For USB Receiver Keyboards:

  • Make sure the USB receiver is plugged into your computer. Try plugging it into a different USB port to rule out a possible faulty port.
  • Look for a connect button on the keyboard and the receiver. Pressing these buttons can help re-sync the devices.

For Bluetooth Keyboards:

  • Go to your computer’s Bluetooth settings and ensure Bluetooth is turned on.
  • Find your keyboard listed among the devices and select “Connect.” If it’s not listed, you might need to pair it again.

Reset the Keyboard

Some keyboards have a reset function that can fix connection issues. Look for a reset button on the keyboard (you might need a paperclip to press it). If there’s no physical reset button, turning the keyboard off and on again can sometimes work as a soft reset.

Check for Interference

Wireless keyboards can be susceptible to interference from other wireless devices. Try turning off other wireless devices nearby to see if that solves the issue. Also, keep the keyboard close to the receiver or your computer to ensure a strong connection.

Update Drivers and Software

Outdated drivers or software can cause connection problems. Check the manufacturer’s website for the latest drivers and software for your keyboard model. If updates are available, download and install them.

Change USB Power Settings

Sometimes, the USB ports on your computer are set to save power by turning off devices. This setting can affect wireless keyboards.

  • On Windows, go to Device Manager, find “Universal Serial Bus controllers,” and check the properties of each USB Root Hub. In the Power Management tab, uncheck “Allow the computer to turn off this device to save power.”
  • On Mac, go to System Preferences, then Energy Saver, and adjust settings to prevent USB ports from being powered down.

Contact Support

If you’ve tried all the above steps and your keyboard still isn’t working, it might be time to contact the manufacturer’s customer support. There could be a hardware issue that requires professional assistance or replacement.


A wireless keyboard not working after changing batteries can be a minor hiccup or a sign of a deeper issue. By systematically checking the batteries, re-establishing the connection, and ensuring there’s no interference, you can usually get your keyboard back up and running. Remember to keep your keyboard’s drivers up to date and adjust your computer’s power settings to avoid similar issues in the future. If all else fails, reaching out to customer support can provide the help you need to resolve the issue.
