In need of temporary SMC related solution.

I have a Late 2008 15" MacBook Pro. Currently without battery, as the battery itself is missing (don't ask). However a battery has been ordered.

Until then, running on AC power only. The issue is: Loud, fast fans; Backlight keyboard not working; charger indicator dimmed; sudden power off.

The main issues being: sudden power off; loud fans. Until the battery is delivered, I need some sort of temporary solution, to bring fans to normal speed as well as stop sudden shut down. The mac "thinks" there is a battery connected, showing the "X" symbol, saying battery low, updating apps suggests plugging into power, when in fact I am running solely off AC Power.

I apologise in advance for the abstract english, it's currently 3am in CPT.

I have tried copious SMC reset methods, as well as PRAM reset methods. It seems, when the power is unplugged, or the SMC is reset, I have to hold the power down, then plug it in, the release power and press power one more time to get it to turn on. This is beginning to be rather irritating.

Please help with temp solution.

Update (12/21/2017)

In case, I'm not the only one, I solved the sudden shut down with the caffeinated command Prevent System Sleep While a Process or Command is Active in Mac OS X.

Sorry I have no magic tricks to solve the missing battery.

But you may have other problems as the system is shutting down due to heat not battery! Download this great app: TG Pro so you can properly diagnose whats causing the system to go into fail safe.

Paste a snapshot and past it here of the main screen so we can see it too.

What did you find running TG Pro? Post a screen capture of the main window for us to see.

As far as caffeinate command line that only stops the system from going into sleep mode from the different possibilities. It doesn't explain your issue with no battery fully shutting down.
