The lithium battery was dead but not at first when I checked it, when I could change it it went slightly more "normal" as I could try to start from the Apple Hardware Test. Else I could only boot in Open Firmware and Single User Mode.
When I tried to startup on the install CD/DVD of 10.2.7, panther, tiger it froze too. However, after the lithium battery change I could install a 10.2.7 on the remaining drive (freeze in the middle but the system seems 100% on the drive).
The drives were OK, as the RAM (checked with memtest, while in SUM it can test 97% of you RAM including lower part not available another way), I counsel Applejack too which enables you to check drives, permissions, clean caches, check preferences while in SUM.
When I tried the AHT i went into something I found out is a commun bug instead of launching AHT i ended up in OF with this:
CODE
Invalid memory access at %SRR0: 000000000.6000d300 %SRR1: 100000000.40003030
Pretty impressive… but not meaning a lot.
As I knew my RAM was ok (even bought 1 GB more to check), the drives too, I tried in turn without the DVD burner, each SATA drives. I had no graphic card to try but overall it looks bad, only the hot pot, the temp sensors, the motherboard and the CPU are left, and no Applecare I have either (sorry Mr Apple, too expensive and never a mac has left me this way, NEVER). It's at the repairshop here in Paris since yesterday, and I ressucitated ye olde timer BW G3 last evening.
I'll buy tomorrow a FW external enclosure for the SATA drive on which I had saved my keychains/mail/etc as here I have no mail (it's my old mail database but I'm under tiger for a few months now and the databases are not compatible).
So in the end, it looks like it's something on the motherboard wich is blown in some way, so it'll $$$ in the end I know chips/components do die, but it's heartbrake, this was a fabulous computer. I'll know for sure in ten days.
Really, I need a macbook… (and no money for it s…t!)
