Hey Louis, I decided to join the forum, even though I have watched all of your videos and attended your tutoring! I have a 820-2915 that is showing the wifi symbol crossed out and stating no hardware is installed. In my little experience, I have never encounter this problem that was not software related. Anyone have any ideas on where I should start??

First thing, try known good wifi card/cable.

Second thing, what voltage do you get on each side of L3404?

A "hint" that the wifi card is dead is when it pulls down AP_RESET_CONN_L when all signals are present to create AP_RESET_CONN_L.
