Hi, I was talking to a technician at my local Apple Reseller today about the new PowerBooks. I've got one on backorder and it's due sometime before the end of the week (yay!). Anyway, when I asked if he could install some RAM I'd bought, he asked if it had "V-Data" printed on it anywhere... I asked what difference "V-Data" makes and he told me that the 15" models require RAM with "V-Data" or the machine will crash on startup. What disturbs me is that I've bought a 1GB stick of RAM from MacSales.com and, although it's guaranteed to work in a 1.67GHz 15", I'm still worried that I'm going to have to send it back - halfway around the world - to get it replaced. I've had a look through the anti-static bag and I can't see any mention of "V-Data" So... this does anyone know anything about this mysterious "V-Data"? Should I be worried, or is this technician-guy pissed off 'cause I won't buy his overpriced Apple RAM? Tim.
