So, my beloved PowerBook has been having a lot of problems recently, the 1 Gb RAM chip is only recognized sometimes, and sometimes it just dies and kernel panics right in the middle of things. I really don't want to buy anything new (I was hoping to wait it out until a 12" MacBook Pro), but is there anything I can do? I'm hoping it's just the chip, but I've heard of RAM slot problems on PowerBooks before, which I really don't want to be happening. Resetting the PSU and reseating the chip will fix it for a while, but the chip will inevitably go. Any ideas? I really don't want to have to replace this one with one from eBay. If it helps, system profiler says it failed diagnostics, pointing to the RAM slot, and under memory, the slot just shows it as empty.
