Hello friends! I am an experienced tech but have never seen that kind of behavior. A laptop came for regular checkup and maybe a new disk complaining also for wifi shutting down many times. I formated it with windows 10 and got it updated fully and all good. Gave it to client only to get it back after 2 days. I tried to test it but after rebooting sometimes it got stuck with this unusual problem.
It sometimes opens after 2 minutes of no screen at all properly on Windows. I can restart it properly but if I press shutdown it refuses to start or it gives a complete black screen no light nothing and after 2-3 minutes it is magically revived. Sometime it does not start at all though. Changed RAM and slots, removed wifi and touchpad, even keyboard doing the same thing. Trief to reflash BIOS from Samsung utility but refuses cause it is the same version. I do not have a BIOS programmer still... Currently I am trying to mess with secure boot and UEFi... What do you think guys??
