Possible Causes

Loose mains plug or internal connector, Overheating main board causing reset, Faulty lid lock signal causing safety shutdown, Failing power supply capacitors

How to Fix / Troubleshooting

Safety first: Unplug before internal checks.

Check external power: Ensure the plug fits tightly in the outlet and the cord is not being tugged.
Inspect internal connectors: Reseat all connectors on the main board, especially mains input and lid lock wiring.
Overheat check: Look for discoloration on the board near power components. If present, replace the main board.
Lid lock test: Wiggle the lid gently during a test run (with water) to see if movement causes shutdown. If so, repair or replace the lid lock assembly.
