I have very unique problem my vaio vpcea42eg laptop power on after complete shut down. for the past 3-4 months I am watching that after I shut down my laptop the green power light goes off and it is complete shut down, but after 6-7 seconds the power light glows again and laptop powers on. I have to hold my power button for few seconds to turn it off but that makes hard disk cranking sound I am afraid if I continue for long like this my hard disk will crash. I have diagnosed in many ways I tried to differentiate between restart and shut down in restart the power green light never goes off and cpu fan is on all the time, in shut down cpu fan stops and power light goes off but after 6-7 seconds laptop starts again, I thought might be windows 10 os problem so I went into bios and from there I selected shut down option from exit menu even then the same process of complete shut down then after 6-7 seconds power on again. only way to switch off my laptop is hold power button for few seconds. can you guys please suggest me what could be the reason behind this auto power on after complete shut down. thank you in advance.
