Hello. My boss finally got the video card he needed for his new mac II so
I figured it would be only a manner of minutes before we were up and running.
Unfortunately this was not the case. After opening the cover, which for
some reason seemed to be a bit difficult to do (the front side wouldn't lift
off even after the rest of it did), we put the card in and then closed the
case. Then, when we tried to boot up, the power wouldn't go on--that is to
say, the machine began to start but as soon as we let go of the button it
didn't "catch" so it just died. Holding the button in didn't help. Finally
I removed the cover again and found that if I pressed the metal contacts
at the front of the unit where the cover normally goes, that the power
would "catch" and then we could use the machine. Trouble is, that after
the cover went back on, it would crash unexpectedly--the power went out.
It seems to have happened whenever the disk was read (either floppy or
hard, after we initialized it and all) after the finder had been loaded.
That is, we got the desktop OK but then if we tried to boot up a program
it often wouldn't work and the system would crash--not always--sometimes
it would take a while, but invariably it would crash. After each crash it
was difficult to start up again since the switch wouldn't "catch".

When we left the cover off things were better--once we started the machine
it didn't seem to crash and when we wanted to start after shutting down,
the contacts at the front were easily pushed or whatever to get it to
start.  As you all can understand, this is completely unacceptable but
we need to know if the problem is correctable or if we have a defective
unit. I know that as I opened the unit I saw that some of the contacts
were bent a tad, but there seeemed to be plenty of contact anyway.

Since I haven't seen anything like this discussed here I suspect this
isn't a usual problem that most mac II owners face. Did those of you who
have gone inside a Mac II have trouble with the front of the cover also
or is this just our unit? Any ideas out there?

Thanks in advance for your help.
