  • Thermal, power-board or mainboard fault requiring service.

Safe checks

01

Record the exact behaviour

Note indicator colour, sounds, displayed logo and elapsed time before shutdown.

What the result means: This distinguishes loss of power from an operating-system restart.

02

Check only the external power path

With the display off, confirm the detachable lead is fully seated and test the approved outlet using site procedures.

What the result means: Do not open covers or probe mains circuitry.

03

Disconnect external accessories

Remove nonessential USB, HDMI and OPS-related external connections, then perform one controlled restart.

What the result means: If stable, reconnect accessories one at a time and record the trigger.
