I know this will sound stupid, but have you checked all the generators are on-line (OH1 panel), and all the hysdraulic systems are powered (R1 panel). It almost sounds as if you are purely running on the battery?
To reset the generators, rotate them fully anti clockwise, and then back to the ON position.
Please don't be mad at me if It's a granny and eggs situation, but I see no-one else has responded to your plea for assistance, and I've only just joined the forum myself. :)
