After several hours of not using it, my powerbook Lombard crashes soon after startup. By the third or fourth try, I think I can hear the disk spinning, but there is no light, no screen, no fan.
I've swapped out the HD. I've added RAM. I've tried booting while zapping the PRAM. And I've used the reset button on the back. It helped very briefly.
On a successul startup I often get the "detected a problem with cache memory" message. For similar (not exactly the same) problems posted in this forum there has been a lot of talk about L2 cache going bad.
Your L2 cache has/is going bad. The only solution is to replace the processor. If you wait, to long it will cause the entire processor to fail and possibly cascade into other parts of the hardware system. --Ted Boliske
Open Apple System Profiler.If it reads L2 Cache 0k, you have bad cache. (should be 512k or 1M)
This one confuses me. If it says its OK, that means it's NOT OK? In my case it said there was no L2 cache.
If it's the L2 cache, do I replace only the cache? Does it mean that I probably SHOULD replace the processor as well, or that I HAVE to? Or do I have to replace the whole logic board? Are they inseperable anyway?
Is it possible that instead/or in addition I need a new fan, too?
