[Marvel/Iron Man 1] When Stark and Yinsen were starting up the Mk 1 armor, what exactly was the laptop doing? Interfacing with the suit somehow?

IIRC, it was the boot-up process to the suit in order to transfer a starting supply of energy from the compound (before it switches to running off his arc reactor), and to initialise the suit's hydraulics. This is why the lights go out when Iron Man activates, and why Tony/the MK1 are unable to move and stop Yinsen prior to the boot-sequence completing.
