Some stickers are made with a water soluble glue, others with an organic soluble glue.
Peel what you can off first, by hand. Once you've pried an edge up, pull slowly and carefully, not letting the angle between laptop surface and label get too large. That encourages separation of lable and glue layer. If it comes off clean, great! If not, fingernails, or a guitar pick can often get the last bits off without surface damage. If you've still got some residue, try soapy water. Give it some time to work, then go with the fingernail/guitar pick. If no joy, the glue is probably organic soluble. Any of the Limonene based orange oil cleaners should take care of that for you. Orange cleaner is available in any hardware store, and most grocery stores.
