Hello. I have a 15" Powerbook G4. 1.33 GHz and I'm running into problems installing new RAM. My upper Memory Slot contains the standard 256 MB of Ram. The second slot was empty until I've recently tried placing the 1GB PC2700 DDR SODIMM APPLE MEM UPG into it. I've done PRAM zaps and NVRAM resets but the system profiler still states that it is empty. Am I missing anything? Is there a way to determine if the RAM has been static shocked? Thanks for your time, -t.
