Hey Thunderer,                        Check the battery compartment. I read some previous posts that it sometimes is located there.
Don't know whether it is in the right section!! Just yesterday when I was putting my laptop in the carry case noticed that I do not have the COA Vista sticker at the bottom of the laptop.  I have a Studio 17 and I cannot find it anywhere, neither on the cds supplied.  Is this normal??  How can I acquire it?? I also have a Dell Inspiron 9400 but I have the COA at the bottom. Any help pls.
