    Dell latitude e5490 auto restart

    Hi guys, can someone help me?

    I have an issue with laptop dell latitude e5490 that auto restart when arrive at certain point in loading windows.
    Board model is dm70 la-f401p rev:1.0 2017-09-20.

    At first, the issue is sometime ssd sata 2.5 not detected. i already try another cable, at certain point, it ok using old cable (i mean sata cable here).
    After a few days test, is seems ok.

    Days later, another issue come, that is auto restart when certain point in loading windows. i already test another ssd, another ram, another sata ribbon, still same. i test another os from usb key, still auto restart. From log data in dell diagnostic, have some issue like graphic and fan malfunction.
    When i stay at bios, auto restart does not happen. i run test dell diagnostic, auto restart does not happen, success with no issue.

    Should i start flashing bios?

    If Dell mentions fan malfunction, check if the fan is running correctly. Also, look for dust buildup inside the machine.
