My 270c/280c still does not boot. The initial chime does not come on. However, the 8 chimes indicating a hardware problem does sound when I turn it on. Well, I got the screen to light up for a split second twice, so I do think that the screen is OK. So, it seems that I have an initial hardware problem before the booting stage.
A couple of people on this list told me to check the RAM. I switched the RAM to my other 280 and it works well. The hard drive appears OK, but beyond putting another hard drive into the 270c with the same result, I have not tested it. So, according to the Apple Service Source book I have a defective logic board to check yet. I guess I could use a replacement logic board. If anyone has one, or thinks maybe I overlooked something else, let me know please. Alternatively, will a 270c screen work on a 280/280c computer that was operating well with a black and white screen since new? Are the chipset and drivers OK in that other good machine, or would I have to change the logic board in that also? I am a novice, but I have changed RAM, hard drives, and trackpads in Duos and am not afraid (at the value of these nowadays) to completely tear it apart. I do like the lightness and size of the machines and others seem to like them also. Also, I tried booting from an auxiliary hard drive with the same result. Maybe someone has tried putting a larger hard drive in these machine. I would love a bigger hard drive. Dan in AZ -- PowerBooks is sponsored by <http://lowendmac.com/> and...
