Hereunder picture is the lower right hand corner of T3-715's motherboard.
The white rectangular in the picture is the location where Acer marks as number 21 & is the location of Power button by Acer's term.
In reality, there is nothing on the actual motherboard of T3-715 at the location marked 21.
Question: WHERE ARE THE PINS OF POWER SW ON ACTUAL MOTHERBOARD OF T3-715 ??
