My g3 700MHz "16 vram" 12 inch iBook doesn't start. I've searched everywhere but find no explanation. I'm new to applefritter, and the folks here seems to be expert(!!!) so might I ask...
Symptoms: last Summer I replaced the internal drive, which had died. No problems with the replacement; drive has been working wonderfully. Later it has occasionally taken a few presses of the power switch to start, but otherwise no problems at all. Once started all would be fine, and this power problem was rare too (only once or twice altogether, until recently). Lately, though, it simply would not start no mater how many tries, until al fin it is now effectively dead. No subtle sound of power surge, no activity in internal nor combo drive.
I've tried (more or less in order): zapping PRAM, resetting PMU, resetting nvram and "reset-all" in open firmware, and every variation of battery in-out, power adapter in-out. I should add that when I've tried the reset PMU key combination with power adapter plugged in the color ring on it changes color for 5 seconds (every time), which might not be significant, but at least indicates that the power switch itself functions.
I should add that it has never showed ANY of the infamous video problems that plague this model.
As I say, I'm not eager to just "run out" and buy a new logic board until I have reason to believe that that would actually fix things! Especially in light of the cost. Any help would be appreciated!! Especially regarding whether it sounds like indeed the logic board is at fault. Or might I have pinched a wire or something--I replaced the internal drive myself, but was very careful and don't think I did that (but it's not impossible). If so, could you suggest where I should look now when I go looking under the hood...
2nd, if I do need a new logic board: I'm confused. Is it true that the 800 and 900 MHz boards are exactly compatible??
3rd, if I do need a logic board: I'm in Germany; any tips on dealers here who sell these cheap?
Thanks a lot for any help!!!
