I replaced many fans and/or deep cleaned vents, heat sinks, etc. This Toshiba P75-A7200 is the 1st of I've seen of its kind where the seams of the bottom tray don't seem to come apart. The keyboard does not come out and there are no screws hidden under the battery. All the replacement parts online are ones that are accessible through pop-out panels only. Are the Toshiba Service Center the only ones that can cut/melt/replace the bottom trays apart?
