I had asked for authoritative information on defective ac adapters which could cause damage to PB 1XX main logic boards. Clark Martin helpfully suggested I could fix the damage if I was willing to do a little soldering.
Doing one last google search, I came across an article in a '95 TidBITS. <http://www.tidbits.com/tb-issues/TidBITS-269.html> Here's the salient info: > The original 15-watt AC power adapters shipped with the first models > of PowerBook computers have damaged a number of PowerBooks. When the > tip of the plug's plastic insulation becomes chipped, inserting it > into a PowerBook - even when it's not plugged into an electrical > outlet - can short out the PowerBook's internal fuse. Later power > adapter models have a reinforced tip that prevents this damage. Apple > has announced a "customer satisfaction program" to replace these > original power adapters and any PowerBook fuses or logic boards > damaged by this problem. > > Only the original model M5140 power adapters, manufactured from August > 1991 through September 1992, exhibit this problem, and only these will > be replaced under the program. The affected adapters have "Model > M5140" printed on their labels, and were shipped with the PowerBook > 100, 140, 145, and 170 models. In PowerBook 100s, damaged fuses can > simply be replaced. In the other models, the fuses are not replaceable > and the logic boards must be exchanged. Apple will offer free > out-of-warranty replacements of the fuse or logic board, as > appropriate. > > Users with these power adapters but without logic board damage may > obtain a free replacement power adapter. PowerBook 100 owners will > receive a 17-watt adapter, and owners of the other affected PowerBook > models will receive a 24-watt adapter. This offer is available only > through 29-Sep-95. Apple assures us that the old power adapters are > being disposed of in an environmentally sound manner. Bless Google and TidBITS!
