This is a question that many people have, and the answer can be different depending on the type of sticker residue that is on the laptop. In most cases, however, there are a few basic steps that can be followed in order to remove the adhesive from a laptop.
The first step is to try to loosen the adhesive by using a gentle solvent. A common option is to use rubbing alcohol, but there are many other options that can be used as well. Simply apply the solvent to a cloth and then rub it onto the sticker residue. Allow the solvent to work for a few minutes, and then try to remove the adhesive with a soft brush or cloth.
If the sticker residue is still clinging to the laptop, a stronger solvent can be used. Be sure to test the solvent on an inconspicuous area of the laptop first, as some solvents can damage the surface. If the stronger solvent is safe to use, apply it to a cloth and then rub it onto the sticker residue. Again, allow it to work for a few minutes and then try to remove the adhesive with a brush or cloth.
If neither of these methods work, it may be necessary to take the laptop to a professional in order to have the adhesive removed. This is often the case with stickers that have been applied in an inconspicuous place, such as on the back of the laptop.
In any case, following these basic steps should help to remove most types of sticker residue from a laptop. As always, be sure to test any solvents or methods on an inconspicuous area of the laptop before applying them to the sticker residue.
