Hello PMDG,Well, I didnt' have problems until today, expect the Radios.Yesterday, suddenly, I opened the PMDG , and bamn, I got nothing working :|.I saw the Battery was off, so I turned it on, and the Stby Power, but, it didn't work, no DC Power either... so I changed to a Cessna to see if I got power, and I had, so it means It's not FS , I think..I think It's a gauge problem, due that part of the switches work, and other part doesn't.I even reinstalled the PMDG, and it didn't help :( I hope I won't need to reinstall FS, big problem due to many addons and AI Traffic... :(I'm really not sure why did this happen, but any help will be appricaited!!I'm puting 2 shots, of the Overhead and the Panel.http://img.photobucket.com/albums/v297/roy...fsscr002aaa.jpghttp://img.photobucket.com/albums/v297/roy...scr003aaaaa.jpgThank you very much!

Check the failures menu and clear all failures.

Nothing was or is checked there...Any other idea?Royi

Nvm, I reinstall FS, It's ok now.

You've depleted your batteries!!Look at the electrical display (with the green numbers). The figure in the left, bottom corner is the voltage of your batteries. You need a replacement battery!The reason for this is usually due to not engaging the generators to let the batteries recharge during the flight. Time to take out that manual and look at the extended start-up checklists.Hope it helps,

Mats, I had the very same problem today, checked manuals and couldn't find any helpful information. I can turn battery and standby power on, but there's no ground power available and I can't start APU! I also tried reinstalling and checking Unlimited battery life on FSUIPC, but that didn't help.Could you please tell what I can do to have me battery back? :)Thanks,

Yes.Start with a fresh NG. No saved scenario file. That way you will have a fresh battery. If you are using a saved scenario and are constantly depleting your battery you will save the bad state of your battery as well.What does your electrical panel tell you about the battery voltage?Hope it helps,

I reinstalled the previous FSUIPC version (3.40) and everything worked fine again ... so good to have the gauges back! :)It was very strange because I always do the correct procedure, not using much battery at all!

Oh ok. Well that's another problem but seems you solved it without any help. :-)Cheers,
