Spacebar Intermittent Issue - XPS 15 9500

More than likely the keyboard will need to be replaced. You should contact Dell Support and initiate replacement.

Thanks for the reply - this is just out of warranty so would likely be out of pocket.

This system requires that the entire palmrest assembly be replaced -- neither the keyboard nor the individual keys is separately replaceable.  While the part is not overly expensive (see below), the entire system needs to be disassembled to replace it, as everything inside the system is attached to the palmrest assembly.

I would rather buy a good quality mechanical keyboard in that price, instead of opening entire computer

Try a compressed can of air, you may be right something is stuck below there

I typically only use the keyboard on the laptop when I am internet surfing/posting so hopefully I can live with it.  

For work, I have a doc and a full size keyboard.

Yikes!  Thanks for the additional info.

What's interesting is it seems to only happen intermittently.  Like as I am replying to this it is working fine.

I would be afraid I would brick this expensive laptop if I took the entire thing apart (but have been known to risk such things lol).

Thank you very much for the info - if it gets that bad I may look into doing it myself.
