商品問答

What is the first limit reached when the VGA output on this 28X5F board runs continuously?

The VGA port on this daughter IO board will sustain its signal as long as the host Latitude E6440 remains powered and thermally stable; no separate duty-cycle limit is defined for the board itself.

How much heat does the 28X5F IO board add when the laptop runs all day?

The board draws minimal power from the motherboard and adds negligible heat; system thermals are governed by the Latitude E6440 main board and cooling assembly.
