Try resetting the PMU by following these instructions;

If that don't work then try resetting the PRAM and NVRAM

Now from past experience, has your friend replaced or added more memory recently to this PowerBook? That can sometime caruse the PowerBook to boot into the firmware.

Doing the recommended PRAM reset should clear it up, and if it doesn't, then the NVRAM reset should do the trick. Single-user mode is useful for some things when you really have to get to the guts of things and use Unix terminal commands; it is a mode to be avoided unless absolutely necessary.

I worked out to reach the screen for firmware commands. You can see from the system-clock status, that Battery is empty since long time.
Otherwise, if i just press power button, I see normal bootup screen with spinning wheel for at least 45 seconds-after that, the Macbook turns down on its own.

Aber ich würde versuchen, und entfernen Sie eines der Speichermodule und versuchen Sie es und starten, wenn das nicht funktionieren, dann versuchen Sie das andere Speichermodul (Wie Sie 2 haben), die jeweils ein in sich selbst, indem es. Schauen Sie, ob das einen Unterschied macht.
