[Solved] Dell Inspiron 15 Keyboard Not Working (Here’s the Fix!)

Dell Inspiron 15s are reliable laptops that pack a ton of value and features in the $300 to $500 range.

Despite the Inspiron 15 being fairly reliable, some Inspiron 15 laptops might exhibit keyboard errors and malfunctions. Worry not – we will walk you through some troubleshooting tips to fix your malfunctioning keyboard.


How Can I Fix My Dell Inspiron 15’s Keyboard Problems?

Driver errors, system updates, malware, and hardware issues can cause your Dell Inspiron 15’s keyboard to stop working.

If your Dell Inspiron 15’s is not working, here are a few troubleshooting methods that you can do to restore keyboard functionality.

Restart Your Laptop

If your laptop keyboard was working fine the other day yet suddenly stopped working just a while ago, a simple restart/reboot might do the trick.

For some reason, Windows sometimes fails to load the necessary drivers that touchpads and keyboards need to function. Restarting should reload all the required drivers and restore full functionality on your keyboard.

Clean Your Keyboard

Although a rare occurrence, debris, and other electrically conductive materials might be shorting out your keyboard from the inside, which could cause the keyboard to stop functioning altogether.

Try cleaning out your laptop’s keyboard by turning it upside down and giving it a few puffs of air. If you have a can of pressurized air laying around, the better.

Another method you can try is to use a small fine brush to brush away all the debris and dirt stuck within the crevasses of your laptop’s keyboard.

System Restore

If your Dell Inspiron 15 keyboard stopped working after a system update, a System Restore should bring your PC back to the last known working version.

Windows updates and other software patches can sometimes introduce driver conflicts in devices such as touchpads, USB Ports, and keyboards.

How to do a System Restore on Windows

  1. Right-click on the Windows Start Button
  2. Select System
  3. Under the About section, scroll down and look for Advanced system settings under Related settings
  4. Under the System Properties window, click on the System Protection tab
  5. Click on System Restore
  6. Select the Restore Point where your keyboard was known to be working

If a faulty update was causing your keyboard to stop working, then initiating a system restore to the last known working period should restore keyboard functionality.

Reinstall Dell Keyboard Drivers

If restarting, cleaning your keyboard, or doing a System Restore doesn’t work, you can try to reinstall your Dell keyboard drivers instead.

There are instances when keyboards suddenly stop working due to a corrupted keyboard driver. Reinstalling the Windows keyboard driver for your laptop’s keyboard should fix the problem.

How to reinstall Dell keyboard drivers

  1. Right-click on the Windows Start Button
  2. Left-click on Device Manager

Windows should automatically reinstall all the necessary keyboard drivers through the method above.

If your keyboard still doesn’t work, try restarting your laptop, as driver changes often need a complete restart to function properly.

Is it worth repairing the Dell Inspiron 15?

Depending on how old your Dell Inspiron 15 is, it might not be worth going through all the trouble to have it fixed by a third-party service center.

The Dell Inspiron 15 is an entry-level laptop, which means that Dell had to compromise on materials and components somehow to keep the retail price down.

If you happen to know somebody who can source and replace the keyboard assembly for you for a small fee, then lucky you. However, if you’re going through a reputable service center to have your keyboard fixed, then prepare to pay a hefty sum to have your laptop fixed.

Most of the time, repairing entry-level gear and electronics such as the Dell Inspiron 15 will end up costing almost as much as the laptop itself when new. In most cases, just shelling out for a completely new model would be the best option.
