Hi all, a friend of mine just rang to say that their new macbook will not startup, just gives 3 beeps. I've looked this up and it seems there are no accessible banks of RAM. It was working fine prior to this. I have got her to take the chips out and try them one at a time, to now avail. My question is, is this likely to be as simple as getting new RAM, or is it something more terminal? She has been living on an island with an erratic power supply for a few months (run off a wind turbine and a diesel generator). By no means a clean power supply. My thinking is the fluctuating power may be the cause, and have suggested that in future she use a surge protector. Any thoughts? Thanks!
