The problem I am having is noise that the computer is making when the firewire is plugged into it with the Firepod. When the power cord isn't plugged into the computer, the noise ceases but when I plug the firepod into it in any combination of the firewire outs, etc I get this noise. This noise stops for a second when I click on something or other wierd actions like that.
Anyone have a solution? -------------------- -Shawn

Did anyone get to try swapping power supplies on their powerbooks? Laptops are double insulated, no earth, so hooking up to a studio and suddenly finding noises and maybe even a tingle in your fingers would mean you could have earthing / power supply problems..I've had serious buzz noises when using landline phones and typing / surfing at the same time with the mains lead plugged in, not when on battery, shortly before my mains lead burst into flames! I kid you not, little blue flames right where it went into the mains plug. I chopped off the plug, stripped back and fitted a standard uk 3 pin mains to it and all is well, no noise anymore...A sure sign would be charging problems or the little light on the power plug not lighting when you plug it in or going intermittent.
