My MacII for some reason decided to not turn on. Both the keyboard switch and the little button on the back do not work. I checked the fuses in the power supply and they are good. Any ideas from anyone out there? (Yes, the power cord supplies power)

I tried everything to fix it, including re-setting the SIMMs in case they were loose. Eventually unplugging and replugging the mouse into the ADB port in the back let it turn on. I never found out the problem, but I don't ask questions. David Fry fry@math.harvard.EDU Department of Mathematics fry@huma1.bitnet Harvard University ...!harvard!huma1!fry Cambridge, MA 02138

Several months ago I discussed the Mac II power-on problem in great detail on USENET. You must have missed the discussion. Anyways, there is a known power-on problem with Mac II's that has the symptom described by Bob. My mac has this problem and when I queried USENET I found numerous other people who also have the problem. It has to do with the connector between the power supply and the motherboard. The workaround is to unplug the power cord from the back of the Mac for 10-20 seconds then plug it back in. Apple has acknowledged the problem both in an AppleLink message to our campus and then later in an Apple Service notice. Unfortunately for those of us who have this problem, all Apple has done is acknowledge the problem and implement a fix for units in production. They have not offered any retroactive repair policy other than "if you have this problem you should replace the power supply". Thanks, Apple! Admit to a design flaw then ignore the installed user base! A Mac power supply costs $250. My mac failed just outside of warranty. As you can tell, this is a sore subject with me. To those of you who have seen my previous postings about this, I apologize for wasting your time by bringing it up again. But maybe one of these times someone at Apple see this and pass the word along that this is a rotten way to treat your customers...

Thanks to all those who had possible solutions to my mac II problem.
These suggestions included:
1. The problem discussed by Robin Goldstone where unplugging the mac
and waiting 10-20 seconds, then replugging will allow the mac to
turn on.
2. Bad lithium batteries.
3. Bad connection on the adb bus
Unfortunately none of these suggestions applied to my mac. I did get
this report from Bill Buikema here at UC:

I'm pursuing this line of attack.

I just got a bill for $289 for repairing (instead of replacing for $400) my Mac II power supply. The repairman said that it had overheated, but it sounds like it might have been something else (I wasn't in the habit of leaving the machine one for long periods when it broke). I have put up with this problem for over a year. One place replaced the motherboard ($400), and the problem resurfaced again (after the warranty ran out, unconveniently). I spent $30 on replacement batteries, and another $40 for someone to tell me that my power supply was good. Thanks to Apple for providing this service. I guess it's just bad luck that I already got it fixed, and that if the warranty had been 1 year in the first place I would have gotten it fixed a year ago. -- ...David Elliott ...dce@smsc.sony.com | ...!{uunet,mips}!sonyusa!dce ...(408)944-4073 ...Krusty says: Give a hoot, read a book!
