Dell XPS 15 Fn key stopped working

Question

For 3 years, I've used my Fn without a problem. I've used it to switch between my F5 key and the play/pause button for example. And I've most often used it to turn my arrow keys into PgUp/PgDn/Home/End keys. I'm also familiar with the Fn lock with the escape key. But a few months ago it started becoming less reliable and now it doesn't really work at all. I don't really care about the media keys, but I can't execute PgUp/PgDn or Home/End without an external keyboard now.

Is there some software setting to allow me to get to a Home/End PgUp/PgDn command?

Is there a hardware solution that I might try to address it? I am comfortable taking a screwdriver to the hardware (less so with a soldering iron though).

Answer 1

From your description and the fact that an external keyboard works fine, you need to replace the keyboard. These are normally a field replaceable unit and do not require soldering.

You can get one from Dell Parts or you might even try eBay as things like this are commonly available that way. I have purchased replacement screens on eBay and prices are usually reasonable.

Answer 2

An ideal solution would be replacing the keyboard. That way, you wouldn't need to rely on third-party remapping software and you'd be able to use all the keys on the keyboard as they're meant to be used. Here's a video of a keyboard replacement for your model. It looks quite complicated for just replacing the keyboard.

If you'd rather go the software "band-aid" route, try looking at AutoHotKey. It is possible to remap keys using that. It's really up to you whether you want to spend the time and money replacing the keyboard. If it were me, I'd try to make do with the software solution.
