Suddenly my MacIIx won't turn on when I push the startup button on the keyboard. Switching keyboards with a working machine doesn't help. Anybody have any suggestions? I have had intermittent problems of this sort before, but they previously always went away if I pushed the start button enough times.

This used to happen to me on my II, and kept happening when that same II became a IIfx, which pretty much exonerates the motherboard. It went away when I stopped keeping my machine on its side. Are you using one of those vertical stands? -- Kevin O'Gorman ( kevin@kosman.UUCP, kevin%kosman.uucp@nrc.com ) voice: 805-984-8042 Vital Computer Systems, 5115 Beachcomber, Oxnard, CA 93035 Non-Disclaimer: my boss is me, and he stands behind everything I say.

Yes, I am keeping my machine on its side, using a Kensington stand. How in the world could this affect the ADB turnon signal? I'd hate to have the cpu take back all that desk real estate. .

This is because the hard disk is mounted with the read/write arm mounted sideways. This means that when you lay the Mac on its side the read/write arm is forced to move against gravity. This wears the arm out quicker. Apple can determine (I am told) that the wear has been caused by incorrectly placing the box on its side and they will not repair it under warrenty. However, if you own a Mac IIcx or a Mac IIci, you *can* lay the Mac on its side. This is stated in the manual. However, you should do a low level format in whatever position you place the Mac IIcx or IIci in and leave it in that position. I found this out when I spoke to a helpful person at The MacZone. I wanted to purchase this Kensington stand and he said I should *not* buy it (it was for a Mac IIfx) because it is not good on the machine! He didn't make a sale, but he made himself a very happy customer. I also want to say that the Apple dealer told me that I *could* mount that very same IIfx on its side with no problem and they told me the part was made by Kensington! To answer the above question, it has nothing to do with the ADB signal it has to do with you hard disk and graivty (and possibly wearing out your hard disk)!

Uh Patrick, how will Apple tell if you had your machine on the side? First of all, Apple Dealers who do warrantee repairs don't care, if it does not work they will fix it. Also Apple does not open the HD if they are broken, they ship them off to get reconditioned or they trash them. Whoever TOLD you was wrong. * Origin: Don's Point, Get it? (1:109/421.3425)
