It's very prudent of you to wait rather than force your 280c open. There are some small plastic eyelets that are very often broken off in the process of cracking open this or any Duo. They're right under your right palm, at the front, right, corner where the top and bottom meet. I would strongly recommend downloading a service manual for your Duo and follow the steps carefully. Unfortunately I don't have a link to follow. Pretty much all the Duos can be upgraded to a PPC by swapping out the logic board with that of a 2300. Everything else will match up. However you will need one of the high output AC adapters (36 watt rather than 25) and there may be an issue of heat if the stiffener/frame/chassis inside doesn't make good contact with the processor. With the PPC upgrade you can install a much larger, cheaper IDE drive (which will require an IDE ribbon cable). As to your sound problem, the speaker gets power from the same ribbon cable that goes to the LCD screen. Perhaps the connection at the speaker, or where the video cable connects to the logic board is not properly seated. Or it could be a software problem (sound out selection in control panel etc.). You may try to zap the PRAM and see if that resets any defaults related to sound. HTH, -makmac -- PowerBooks is sponsored by <http://lowendmac.com/> and...
