Has anybody run in trouble installing this accelerator chip?

I pulled out the old chip, popped in the this upgrade, and the computer wouldn't boot. I put the old one back in, still wouldn't boot.

I'm wondering if my BW g3 is completely hosed.....*sigh* How's that even possible? the instructions are really simple.

sorry dude but it sounds like your mobo is hosed. sucks. what have u tried? you said it now wont boot from ur old processor? do u hear a starup chime? do u hear the hardrive clicking? do u get any video on the screen, or u get the grey screen? try pressing the reset button on the mobo. was ur mac working good b4 u attemted to install the powerlogix chip?

Check the pins on the 800 zif and see if they are all there..if not ..there might be one left in socket. It might be shorting something...dunno.

I can't remember how many cpu's I've seen with bent pins that felt ready to fall out..and some have

Have you also zapped PRAM and reset any switches and all that?

Best of luck.

Don't give up.. I'm no Apple pro.. but I'm an old hack at AMD/Intel hardware...

Playing around with my G4 desktop uptrading it from a 450 to a dual 500 I found it can act crazy for no reason.

I had the same prob as you and though I had killed it. I put in the new cpu and nothing, put the old one in, nothing. I GASP, as I though I'd killed it. I zapped the pram still nothing. I let it sit for a half a day zapped the ram again and it woked. I've duplicated this.. but it makes no sence.

For some reason Apple hardware can act crazy. i doubt you killed it. Try taking the battery out of it, zapp the pram (if the old beige ones have a pram, I don't think they do) and let it sit... sacrifice a small animal and try again.

hehe...thanks for vote of hope.

Umm...I tried all those things guys. I don't think I burned out the chip from Powerlogix, but I did notice that it seemed to be missing two pins. I'm not quite sure since I wasn't paying 100% attention to how the things looked. I didn't force it in or anything either, it just slid in like butter as it is supposed to.

If it is indeed a problem with some pins coming off and remaining inside the socket, how am I supposed to fix it?

That sounds very ugly, especially considering I don't have any screwdrivers or anything that can fix into that kind of hole opening in the ZIF socket.

I pressed the internal button (CDA button or whatever it's called) that's suppposed to reset the motherboard. I haven't tried zapping the PRAM. Like I said...I'll turn on the computer, I get zero response other than the power coming on and the fan working, there's nothing on the display though.

What battery do I need to pull out? the Clock battery?

I'll have to try the PRAM reset. that's the only thing I haven't done. Oh and maybe attempting to restart from cd-rom to check if the motherboard is hosed or anything (I have to pull out the dvd-rom to do that, it's a pain but a must).

Bleah...the sad part about all this is I have like the worst luck
historically with this machine...endless problems getting upgrades to work smoothly.

The first card I got from PL was defective. It took noticeably more that "zero" force to insert, and it appeared to have a couple of broken off pins.

It didn't work, but after removing it, my old G3 350 still worked.

I got a replacement last week and it works great, even running at 850.
It IS supposed to be missing more pins than just the one in the corner, BTW.

Their return support, handled by a place called Waypoint Distributrion is excellent.

I can't imagine why your B&W would refuse to boot even with the old one in place. If a pin had broken off the new one, you would not have been able to put your old one back in.

call her and she will set you straight

^ lol...

Yeah, that's what I find baffling...the old g3 one slides in with no problem, and yet it won't boot up again even after pressing that button on the motherboard.

You know, it never hurts to check EVERYTHING out once you have been inside your Mac. For instance, once time I was trying to fix a RAM problem, and I cracked my case open at least a dozen times. One of the times I did that must have jarred the jumper block on my MoBo, because after tearing out my hair trying to figure out why it wouldn't boot, I found one of the jumpers sitting innocently in back of the case.

Even the tiniest thing can cause a Mac to not boot. I hope it's one of those things causing your problem.
