Should the machine show a menu bar symbol that it is plugged in? I seem to remember one on another machine that I ran OSX on. What are the symptoms of a bad power board?

The batteries age by increasing their internal impedance (voltage drop under load) as well as by capacity (amp-hours) loss. They can show a fairly full gas gauge (reasonable no lo…

I am typing this on the G5. After about three hours today, and an hour yesterday, plus two hours at Fry's (They only had one capacitor. The guy had to find the other one. I also ha…

Try the battery in the right hand expansion bay with the machine first running on AC also, and again ignore the status icon and just pull AC power to see if the Lombard switches ov…

So your able to fix it? BTW that quicksilver rocks! Thanks again.

It was not a resistor that burned - it was a capacitor. My friend mis-identified it.

Hm. I'll have to give that a try then. But I hope you'll forgive me if I try wally's method and the open firmware one first Did you do this on lithium batteries, or the "Inte…

there is a way to reset the battery power manager. Take a wire and short both the + and - terminals. It will short out the power manager and reset it. Click to expand... Now,…

I have another G5 that just sits in my bedroom collecting dust - a Dual Core 2.3 GHz model with PCI Express, that I got for $150 - it freezes up about 10 minutes after you use it, …

Luckily you've got that macbookpro, and USB/SATA adapters so you c an get your data off of the G5 are not that expensive.

While I hope that your cheerful optimism proves out, it may turn out that the burned resistors are a symptom, not a cause. Resistors are pretty hardy, and not generally given to sp…

Hey I had a B&W 17" with the exact same problem a couple years ago. I tossed it, figuring it was unfixable. It was by me. But I guess not by everyone. Too bad, I guess.

Yes that is exactly the problem I had. From what I understand it is a common problem with those displays.

I had a B&W 17" Apple CRT display that had a failing flyback. I bought a new flyback off eBay for about $20 and it took me about an afternoon to install it. Of course th…

I've never opened up an AIO, so I am unsure of its specific anatomy. But based on my experience with many color TVs and monitors, here are some hints: First, identify where the ar…

Well, should you want to try the shorting trick be sure to check for very low energy on those terminals first, we do not know that all packs will be in a safe cooperative state! M…

It's great to hear that you got it to work that way, Wally. Very interesting! I'll have to give your method a try (and maybe the "short + and -" method, too) the next time I have …
