Never had this problem, always nice to get a new one! My laptop is doing strange things with its integrated keyboard, I cant create a capital C from the right shift button. Other letters are fine though!
Every now and again, the dialog boxes in Windows throw a wobbler, like there is a stuck key. Flashing around, if you click on an email in Outlook it opens and pops out rather than previewing. If I hit the right shift, it goes back to normal for a while.
I've updated the BIOS to the latest revision, even reinstalled Windows. Not really sure what to do with it. I thought a keyboard fault would be a bit more involved!
The machine is quite clean and healthy - nothing stuck in the keys or anything, puzzler!
