Thought I’d update on the status of this iBook, I managed to find another identical 466mhz Graphite SE untested on eBay for only £75. Plugged it in and it booted straight into Mac OS 9.0.4! Also had a 256mb sodimm and an airport card in it! It had some cosmetic issues and the dvd drive was...

I’ve been staring at this board all week, it’s still beeping at me ! I decided to try replacing the ram chips using ones from the sodimm that came with the laptop. Original chips were MT48LC8M16A2TC-8E-B and the replacements are NEC D45128163G5-A80-9JF. Datasheets seem to match from what I can...

Ok thanks so basically I should never expect 1 beep on a board with soldered RAM as BootROM is always going to look for it?

Update from this evening, I went ahead and removed the soldered ram chips. Was fairly straightforward with a heat gun and seem to have got away with not damaging too much! Unfortunately it doesn’t seem to have changed things, after I removed the first two I no longer got a chime but got the 3...

@MacUp72 Thanks for the advice, It looks to be ok and I’ve tested it, 0.760 in one direction and infinite resistance in the other which I think is normal? @croissantking right you are I have tested them and they all have continuity. Incidentally I then found this useful link with scans of...

After some more investigating this evening I found this row of capacitors which looks like it could have burned out. Can’t see any others that look this dark so assuming they are the source of the burning smell! They are next to the ram chip and appear to be en route to the cpu/northchip. Will...

Hi All, I’m attempting to fix a 466mhz iBook G3 SE Graphite I recently bought and would appreciate some guidance on what to look for next. On booting the iBook chimes and then beeps 3 times (no good banks) I get nothing on the display. HD and DVD drive appear to be functioning, and I’m able...
