Hello,

One of my users has a Dell Latitude E6510, and randomly, even when they are not typing, a key continuously types as if it was pressed down or stuck. The user says the keybaord is not actually getting stuck, and sometimes he is not even typing. It has happened more than 5 times in the last month.

Any idea what is going on here?

The keyboard may be defective.  This is possible even though no keys are being pressed.

To diagnose:  Swap it out for a known good unit.  If the problem is alleviated, the keyboard is bad - throw it out and replace it with a known good keyboard.  If the problem persists, other avenues can be investigated, such as a faulty keyboard controller (PS/2 keyboard) or USB problems (USB keyboard).

Press one key (preferrably known not to be sticky) 5 times. An ease of access window will pop up Go to settings and see if you have set sticky keys to be on. You can also go to Control Panel -> Ease of Access. ... Thinkpads_User

is it the same key everytime?  which one?
I would reseat the keyboard (disconnect from mainboard and reconnect) and see if the problem is resolved, if not, boot from a Ubuntoo Live CD or a different OS on a different HDD to see if the problem could be software/driver related.

you can test the hardware when booted from a live cd - that should help you diagnose ; here a couple :

Hmm, okay, great suggestions. I have dell pro warranty support, so I am probably going to put it on them seeing as it sounds like most of your believe it is hardware related. If that doesnt work I will try the other suggestions.

Thanks guys! I will award points once I have a confirmed solution.
