Windows 7: #9 icon in system tray

I'm setting up a new Dell laptop for someone and there is a square black icon in the system tray with a white "9" in it. Left or right clicking it does nothing and hovering shows nothing. I have already uninstalled and disabled a bunch of stuff but I still haven't figured this one out. I've Googled a bit and although others have seen it, no one has a cure that is applicable on this laptop.
Anyone know what this is?

notification icon for number lock maybe

try turning off numlock (keyboard option on your number keys) see if it goes

this is a long shot but im sure ive seen it before

McAfee VirusScan 9 email scanner ? or maybe Logictech malware.

Press the num lock key (may be in conjunction with the Fn key) and it will go away. This is a Dell special.

I was right then i thought id come across this before

I could swear I tried the NumLock key before and it didn't work. But that was it. It turns the "9" off and on and the Fn key is not needed. I wonder how the number 9 is supposed to correlate to Caps Lock :-)
Thanks.

I just go off chatting with Dell. The Icon that you are referring to is actually a application "Quick set" that works for the shortcuts of the keyboard. You can disable it by using msconfig, and turning off the Dell Quickset in the startup tab.

However, if you turn it off you can't use quickset. On my Inspiron 14 laptop, that means I can't control the volume, brightness, and media controls. So you basically have to live with it. Not to smart on Dell's part.
