Laptop Graphics System: open circuit or connection. A pin, trace, socket or component no longer carries its required signal.

The distinguishing clue

One rail or channel is absent while neighbouring stages work.

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: Trace continuity and signal progression with power isolated where required. If confirmed: Repair the open path and its mechanical or thermal cause.

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

Related cause to rule out

When the fault changes with temperature or chassis flex, also consider Laptop Graphics System: intermittent solder joint before choosing a repair.

Checks after the work

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