The above laptop has been working flawlessly but today shutdown unexpectedly and now fails to start. The power light lights for 5 or 6 seconds and then goes off so its presumably failing the POST. Does the same with or without the power supply connected. I added a second M2 SSD (Samsung 970) shortly after receiving it but has been working fine since. Have emailed but just wondering if there's anything I can try to rectify the situation.
