I just picked up an 8100/100 AV on the side of the road... It chimes when I turn it on, but then it just sits there. No, flashing ? disk. I have tried booting from CD, putting in an alternative HD with system and nothing... What else should I check? I have reseated the AV card multiple times. Any thoughts?

Would a dead battery cause this?

I've had similar situations with batteries. Revived many a dead mac this way.

If you got an 8100 for free because someone didn't know to change the battery, you're a lucky guy.

I have replaced the battery. It still doesn't work. Argh! I am using the AV card' monitor port and wondering if the card is bad. Unfortunately I don't have one of those proprietary Monitor plugs that come with this machine. Any other thoughts? Thanks so far!

take the battery out and look on the motherboard for a tiny little reset switch..that might help

then put the battery back

and you could also disconnect everything but the floppy drive and see if it will start up and then add stuff back once at a time.

Maybe you should try taking the video card out and then putting it back in. It might not be seated correctly and taking it out and replacing it might help.

Also, it's possible that if the monitor you're trying with it is newer than the machine itself, the video card might not support the monitor.

When I read your first post, "dead battery" popped right into my head, but it probably isn't that since you tried replacing the battery.

It's also possible that there isn't a system folder on the hard drive. If this is the case, you should be able to start up from a floppy disk.

I've gutted the whole thing and am down to the barebones. Motherboard, AV card, and floppy drive. I've even removed all extra RAM. No dice. In fact now I've lost the gray screen. It is just black now. Argghh! It seems we have covered most of the possible problems. Any last resorts? Thanks

Hi Dan,
Sounds like you have covered all of your bases... one other possibility... the ROM chip might be unseated, or defective... check to see if it is down all the way...
just my two cents... (which isn't very much :-)

Well, that was the trick... The ROM was loose. Thanks to all who helped out!
