Q605 won't boot

[Sharkonwheels]

Got a (in my sig) Q605 - 33Mhz hack, full RC040, 64MB SIMM, 250MB hard disk, PDS etherent, I think MacOS 8.1

It was put away working about 2-3 years go.

Pull it out, nothing.

Dug out a good battery from my inventory (read: garage) and popped it in.

I can hear the startup chime, and then I hear this 8-10 note song, but no video, nothing.

Removed 64MB SIMM, same deal. Removed Ethernet card, same.

Any ideas? Never heard a Mac sing like that...of course, hopefully it's not a death chant...

That sounds like a death chime. What happens if you disconnect the HDD?

Also, are you sure that the battery is good? Check it with a multimeter. (if you have one) Also, even if you're sure that the battery is good, try doing the "Pizzabox Powertoggle" anyway - turn the machine on, then off, then back on again.

Best of luck.

A dead battery wouldn't give you the chimes. In my experience, the chimes of death are caused by bad memory most of the time. I would remove the RAM and the PDS card and give it a reboot. If it boots without the PDS and the SIMM, put the PDS back in and try it again.

I distinctly remember that I had an LC475 (same machine) give me the chimes because of a bad 80 MB Hard Drive.

Try another drive, any scsi at all, and see if the chimes recur.

According to Macs For Dummies 4th Edition by David Pogue, the chime is usually caused by bad/loose memory or a SCSI conflict.

 

[Sharkonwheels]

Removed the SIMM already, still sings.

Unplugged the SCSI drive, same deal.

She dead and need to be buried?

Shame - I LOVE Q605's!

You could try reseating the onboard memory.

 

[Sharkonwheels]

Onboard is soldered to the logic board, unfortunately

Are there any telltale signs of leaking caps? The 605 is so darn cute, it would be a shame to give up. In desperation, I'd just toss it in the dishwasher, even if you don't see any obvious leakage.

 

[Sharkonwheels]

Well, I do have one of those RatShack electronic cleaner cans with the scrub brush on it. I could just scrub the life out of it and see....

Can't see any bad caps...

I hate to sound like those people who say, "Maybe if I just let it sit for awhile it will fix itself," but...

... I have revived a couple of mysteriously dead Macs (no power at all, or chimes of death) by unplugging everything from the motherboard - PRAM battery, hard drive, floppy drive, RAM, VRAM, CPU, anything not nailed down or soldered on - and letting it sit for several days, and then reassembling it.

Sounds weird I know, but perhaps worth a shot before you dumpster the mobo.
