Well, I think my power brick is about to die on me - the connector strain relief has split, and it's frayed/shorting $75.00? Also, my 550mhz PMU is on the fritz - after getting a new (free, within warranty) replacement battery, my powerbook charges up to 20% - then jumps to full. Conversely, it discharges from 100% to 60% then to 0%. $????.00 I have tried everything short of a reinstall of software (running latest version of Tiger) for the PMU - Open Firmware reset, PMU reset, etc... I take it the PMU is integrated into this version of the PB? So, for the power brick... Any brands recommended? I like the straight plug. And the PMU... Is it integrated into the logic board on the 550 Ti? Thanks! John Pariseau
