Fix for T3 screen not retracting!
Scott, I had the issue one time after I actually opened the unit to upgrade memory and hardrive.
If you look closely at the screen where the hinges meet, there is a little button that gets depressed when the screen is level and ready to retract back into the unit. If the screen gets slightly bent upwards, it does not meet the contact on the button.
The button tells the infill that it is horizontal and ready to retract. If you pull down on the screen right when it is almost horizontal, I bet it will retract. I used a little extra force with the power off to try and align the screen better to hit that button. It worked! You could also put a dab of glue or epoxy to make the button stick up a little more(Let it dry overnight!!!).
I hope you didnt send it in yet. When it happened to me I thought it was done for. Since I "readjusted"...the problem hasn't returned so far and its been 8 months.
Hope this helps.
