I have a brand new (<1 week old) Dell Latitude E6540 with Windows 7 Professional (64-bit) where the occasionally while typing I get a double key press. For example: I am writing a qquestion on superuser.com.
- It is not bound to any particular key, so it is not mechanically broken or anything. There are no signs of damage.
- It does not have its own configuration utility and Windows Device Manager lists the Windows default drivers, "HID Keyboard Device" and "Standard PS/2 Keyboard".
- An external keyboard in lieu of using the built in keyboard is not an option for me.
- Dell forums seems to indicate this was a major problem during with the XPS series between 2010-2011 and most had their keyboards replaced with no success. A user wrote an Autohotkey script which helped a lot of people, but the download links are dead.
- I have tried messing with the "Make the keyboard easier to use" menu in Windows Ease of Access Center in the Control Panel, both Bounce Keys and Repeat Keys and Slow Keys without any success.
What would you try next? Find a replacement driver? Is there some hidden method for debouncing a keyboard?

2Have you contacted Dell? If it's a week old, it's under warranty. – CharlieRB – 2013-11-05T19:08:14.757
Not yet. I'm preferring to avoid it because I've already sunk several days getting a bunch of proprietary software installed, and in the past it wasn't successful, albeit with other models. If I don't get a good solution here, I probably will though. – Ben Mordecai – 2013-11-05T19:18:00.723
3Just make a backup before you call or send it to them. The first thing they'll probably want you to try is format and install the OS fresh. Try booting from a Linux LiveCD (or LiveUSB), and use that for a while, does it occur in there as well? If so, you KNOW it's a hardware problem. – Ƭᴇcʜιᴇ007 – 2013-11-05T20:46:00.207
@techie007 Linux Live boot is a brilliant idea. – Ben Mordecai – 2013-11-05T21:35:42.223
