Quote from their website:
High-quality laptop cleaning is carried out in the following order:
Temperature measurements in the processor and video chip;
Turning off the device's power;
The back cover, the keyboard are disassembled;
Disconnecting the cables from the motherboard;
Removing coolers and cooling systems;
Replacement of the thermal pad, application of a new thermal paste;
Providing lubrication/replacement of the laptop cooler, mounting the cooling system back on the board;
Connecting cables, reverse assembly;
A control test.
As a result, there are no tests either before or after. It seems that they did something, but what is not clear. Maybe they just vacuumed for 15k. According to subjective feelings, nothing has changed much - the laptop warmed up to 60 when surfing the Internet, and it warms up.
