Dell :: Bought M4400 But Tag Does Not Verify

New Dell M4400 user (and new to the forums!)

After giving up with the 1280 resolution on the 13" sony I had for about 2 years, I bought a M4400 2nd hand from a reputable chain of stores in the UK.

It was actually as good as new - all the plastics coverings were still present and untouched both under the laptop and on the palm rest etc. Box was present with all the books/cds sealed
They get a decent supply of Dell and other brands in from resellers/suppliers etc and having worked there in the past, I have no issues with it BUT...

The service tag does NOT validate on the Dell support site. If I type it in another country, it knows that it does not belong to that country.
When I do type it in, it basically says AMERICAS and nothing else.

No warranty information is found, when I hit contact, it basically throws back an error to say the tag was not found.

Have i got anything to worry about?

On another note, while the laptop IS brand new, there are no stickers under the laptop - is this normal on a M4400? The Vista licence sticker is present but under the battery

If It was peeled off, you would know even if it was a slight bit of residue and given that the plastic laminate is still stuck on properly without any signs of it being removed...I am 99.9% sure it never had any stickers on it.

Other than that, I love the laptop - gets a bit warm in the front but it's great otherwise!
