Hello

My fujitsu lifebook t730 laptop died all in sudden while working, it went blank straight away no warning or anything .... now when i am trying to turn it back on .... nothing happens ... no light or any sound at all.......... i tried removing battery and adapter wire and holding power on for 30 second but didn't help........... I even opened it apart to see if any cable went lose or any other sign of issue but don't see any problem... laptop got two batteries and both worked good with no issues at all. ..... any advice or solution will appreciate .... did the power or motherboard dead?? no idea

please help

thank you
