Hi, My new iBook 12" arrived this morning. The first thing I did was to carefully follow the instructions to install the 1 Gb of RAM I purchased from a retailer which arrived last week. (The RAM is "DMS Certified" brand). I fire up the 'book, (continue to) marvel at the niceness of it all, and then after fiddling I hop over to "About this Mac", only to see that I only have 256 Mb of RAM. OK, I thought, this is just because I've never installed RAM before and I'll just need to re-seat the bloody thing. So I open her up, take the memory out, put back in, and fire it back up. 256 Mb. I do it all AGAIN. Still 256 Mb. The current state of affairs: the iBook is charging for battery calibration and the non-detected RAM is still in there. I can see about 1/8" of contacts on the ram; the clips seem to snap into place properly. I have tried pushing in the module with light pressure, but I do not experience much "give", like when the airport card goes in. The clips, nevertheless, seem to be in the right spot. What do I do now, O Macrumors? I need a step by step on getting this working. It would be nice to know the odds on this being 1) A simple (correctable) installation error; 2) My having broken my computer within 5 minutes of owning it; 3) A case of bad memory (will require return) 4) A case of broken computer (will require return) Thanks.
