Lenovo Y50 Touch won't START/POST


May 16, 2017
Lenovo Y50-80 Touch stopped Booting. When pressing START button both the Run and Battery White Leds light for 5 sec. then both turn OFF. Fans do not start, Screen does not turn on with circle motion indicator, HDD doesn't spin up. Had a "Can't write to nnnnnn" error when shutting down but would still shut down and started up until now. Think this was a RAM error...

Checked Battery...indicated 7.7vdc
Replaced RAM (new)
Tried to Boot from USB Win10 memory stick.
Still nothing...

Has been a great little machine but I'm out of ideas.....HELP IF U CAN :)
