Explanation
The key clue is that the display is dim while traveling but normal at home. When traveling, a laptop runs on its internal battery (not plugged into AC power). Windows power plans have a 'balanced' or 'power saver' setting that automatically dims or reduces display brightness when on battery to conserve power. At home, the laptop is presumably connected to AC power, where the display operates at full brightness. This is standard behavior controlled via Power Options in Windows. A defective display or short in the power cord would not produce this consistent, reproducible pattern based solely on power source.
