I bought a new Inspiron 15 5567 a few months ago and have had no issues with it until now. Now when I try to type anything, it acts as if the alt key is pressed (giving special characters such as á or é or triggers keyboard shortcuts e.g. alt tab). I have tried resetting the language, deleting the keyboard driver and restarting the computer with no improvement. Occasionally it will revert to normal for a few seconds but then goes back to being unusable. Any suggestions as to how to fix this?
Have you tried using an external keyboard and does it give the same results? If not, you should try cleaning and blowing out the keyboard with canned air. If none of that is working, the keyboard may need to be replaced.
If you are still under warranty, you should give tech support a call for additional troubleshooting and possible resolution. You can contact Tech Support at 1-800-624-9896 or 1-800-288-4410, or you can initiate a chat session http://dell.to/2v4snVm
