    PB Duo 2300c and 270c Capacitor list

    Do you have a dock?, if so try that and see if an external keyboard works, I would like to say that bad caps would cause this but you might want to dig out a multimeter and start testing the fuses on the logic board as well as other components for continuity. First step is probably to get that...

    Duo 270c - Yay or nay?

    This is kind of off topic but I have a few questions about the duo's. The 270c has a ribbon cable connector on the bottom of the logic board, I have seen this on both a 210 and my 270c, what is this connector? is it for testing purposes. Another thing I witnessed recently after putting my...

    Duo 270c - Yay or nay?

    Duo 270c - Yay or nay?

    Beautiful job on that P-RAM battery. the Duos are such great machines to work because of how simple they are, they also seem to be very reliable, as I've owned three of them and now have two docks (still looking for a minidock) all of which have had no major issues or failures, except my dock...

    Challenger's conquests

    So after many years of radio silence on this forum I decided to come back, I lost about 95 percent of my collection in 2017 to a collapsed shelf, and of all the images I lost the one that saddened me the most was my powerbook duo.  So with many fond memories of the duo I decided I would set out...

    PB Duo 2300c and 270c Capacitor list

    Hi everyone, I am going to start recapping my Duos as I finished Recapping the docks, Does anyone know which capacitors are required for the 2300c and 270c, Also is it worth recapping the displays?, I worry that the heat of a soldering iron could ruin the two near perfect duo screens I have. ...

    New 1400 Battery?
