G3,600, dual usb, unknown OS. inherited, no docs, no CDs, no cords, no peripherals. Sitting unused for unknown time. bought and plugged in charger, charged for an hour, press battery button gets 1 flashing light. Press start button, sound and gray start up screen with moving wheel, forever, electronic/mechaical sounds inside, but no screen change. So far, did pram reset, pmu reset. No change. have not tried safe restart. Newbie to Mac since 15yrs ago. PC literate. What to do next? Worth spending money on? Or is it ready for recycle plan? Thanks. Kerwin in Valley Forge.
