The most common orders they receive are repairs to the screens, the keyboard, the hinges, the logic board, the charging system, and the unibody replacement. These parts could get broken, or they could be affected by spillage that gets into the computer. Every form of damage is treated differently, and the equipment used is specialized. Replacements of these parts may be recommended if they suffer too much damage. The client has to approve such replacements before they can be effected.
