The wegenermedia reference relates to some earlier positive results others mentioned some years
ago, and due to that, I sent an iBook computer to them, in a padded box (over-engineered) that I
made, for diagnostic repair service, and it returned with stickers over the screws that said their
warranty would be void if the tape were damaged or removed. I felt sure enough of their work that
I later sold the computer to an 80+ y/o some miles from where I lived, and chose to give him free
support for two years. That means since he never had used a computer, and saw an ad I put on
a bulletin board in that town and chose to reply to it, I even went as far as helping set up printers
and other things he had never done, at no additional profit to me. The iBook was a complete kit
and included original box, plus later OS X and extras, at below other location retail.
I've been in contact with them about two other computers I have, one is an aluminum PowerBookG4
and the other a MacBook1.1 13-inch 1.83GHz first-model, each has issues. The MB1.1 is better, &
it only needs some parts to fix two issues, but it runs well. An occasional winking display, that does
best if left sitting with lid open; and by use of iStat Pro, I see odd information from the CPU temps on
one of the two cores in the processor. Sometimes, it says the core is sub-zero °F, other times hotter
than the other one. And also, it may disappear from the reporting to iStat altogether. So that may be
as simple as a need for new thermal paste if the CPU could be so doctored. They will inspect and
test an item before a firm cost estimate is arrived at. They've also workstations to repair logic boards.
So I'd be willing to bundle up my early MacBook1.1 1.83GHz and send it off for a $200 service, since
once it is opened most issues can be dealt with on the spot, and it would be returned with warranty.
Since my example is a clean one, it may be worth that service. It has 10.5.8; could run 10.6.8 OK.
Anyway, the discussion is a bit afield from the OP topic, except there are experts who can repair an
original logic board; some prefer to see and test the entire machine. Others may swap out the board
for one they've already serviced if available, for turnaround-time sake. They offer older refurbs, too.
Between the sales model number and processor version it should be easier to locate a replacement
for the original post's questionable part issue. Some devices had additional part numbers that may
work, depending on the length of product run and changes in manufacture over the duration.
{Seems to me you'd gone from using Macs awhile, to PC, and were in state of ID awhile, btw.
And the reference email I have, is your first + last name at gmail.}
In any event...
Good luck! 🙂
