Based on the information provided, the most probable cause of the laptop shutting down unexpectedly when it's moved from one room to another is system overheating.
When a laptop is moved, it's possible that the internal components shift, causing the cooling system to become ineffective. The cooling system of a laptop typically consists of a fan and heat sink that work together to dissipate heat generated by the processor, graphics card, and other components. If the cooling system isn't working correctly, the temperature inside the laptop will increase rapidly, causing the system to shut down to prevent damage.
Reseating the hard drive, memory, battery, and LCD cable wouldn't have any impact on the cooling system, so it's unlikely that these components are causing the issue. Residual energy on the motherboard, distended capacitors, and CMOS battery failure could potentially cause system instability, but they're less likely to be the cause of the issue than system overheating.
To confirm whether the laptop is overheating, the technician should check the temperature of the processor and other components using hardware diagnostic tools. The technician should also check that the fan is working correctly and the air vents aren't blocked by dust or debris. If the laptop is overheating, the technician should clean the fan and heat sink and replace any faulty components to restore proper cooling.
