Problems with electrical are. I previously wrote, but I will write again:
"If you do not start the engines, then after 5-6 minutes power supply is lost and can not be restored without reload aircraft. At the same time there is ground power, working APU, batteries are not discharged"

All that remains in force.
It may seem that the power have because the bulbs are lit, backlit panels work. But we can not start the engines. And before (step II - 0.x) disappearing dome light. But now (1.0) it does not work at all and it is not so evident.
That is, impossible to perform on such a flight plan:
- Connect the power supply (EP or APU)
- boarding
- preflight procedures and load data in PDCS
- pushback
- Start the engine
and so on...
We must immediately start the engines, and then it will be impossible.
