Laptop Graphics System: heat-sensitive board component. Cooling, solder fatigue or internal degradation makes a board component unstable under load.

The distinguishing clue

Crashes appear at a repeatable temperature or workload.

Checks before an assessment

Record whether the built-in screen and an external monitor fail together, and whether the issue begins during graphics load or display switching. Do not use heat or reflow tricks.

Stop point: Uncontrolled heating or reflow is not a reliable repair.

Workshop confirmation and repair

Device-level check: Compare internal and external output, temperature, power and software behaviour.

Targeted check: Log temperature, clock and power while testing cooling first. If confirmed: Repair cooling or replace the confirmed damaged component.

Repair boundary: Repair cooling, power, firmware or the confirmed graphics board path.

Related cause to rule out

When the computer works at light load but becomes unstable as demand changes, also consider Laptop Graphics Faults: Compare Screens Before Blaming the GPU before choosing a repair.

Checks after the work

After repair or replacement, check internal display, external display, video, graphics load and sleep.
