Does the Notebook overheat? I suggest you run an extensive system test and let me know if the Notebook shuts down during the test

- Shut down the Notebook completely
- Turn it back on, then tap the Esc key repeatedly until the Startup menu screen is displayed.
- Press F2 to select System Diagnostics.
- Click System Tests, then click Extensive Test.
 

Thank you
