Portal 2 Hints
Once there, how can I raise the moving platform?
1 of 6: Go to the back of the main room, then turn right to find the doorway into the actual control room.
2 of 6: Move up to the desk to get the bird off of GLaDOS, then look for a control that you can use to raise the moving platform.
3 of 6: Notice the sign on the desk next to the nest that says "ELEVATOR CONTROL."
4 of 6: Maybe the nest was built around the control button.
5 of 6: Move up to the nest and pick up GLaDOS when the game will let you.
6 of 6: That will reveal the control button, which will fizzle and spark, causing the moving platform to rise to its "up" position.
