I need to get some info off my old Powerbook G3 (Wallstreet edition). I think the internal battery is dead. Any suggestions as to where to get the battery (for cheap!)? |

Thanks for the help, Dave. But I think I need a different kind of battery. Here is the situation:
I got a new G5 computer last month. I put my old Powerbook safely in the closet (when I shut it down before making the switch to the G5, everyone worked fine). Yesterday I needed some info, so I plugged it back in. Nothing happened. This happened about four years ago and I had to replace some kind of internal battery, not the removable battery.
Any suggestions or places to call for help.
Thanks again. |

It's possible that the PRAM battery (or at least what we will call the PRAM battery) is dead and needs replaced, go to this page for instructions on replacing it, http://homepage.mac.com/sysop/PhotoAlbum3.html
The (PRAM) battery is shown in image #24.
It could also be that the LiON battery has given up the ghost is completly dead and can't be recharged.
That being said, what happens when you take the battery out and try to start it with the A/C plugged in?
Try restting the PMU by doing the following,
1 Shut down PowerBook
2 Unplug the AC adapter
3 Press Shift-Fn-Ctrl-Power (at the same time) to reset the Power Manager
4 Wait approximately 5 seconds (the "sleep" LED will blink once)
5 Plug the AC adapter back in
6 Restart the PowerBook

WOW, I thought Mac's are easy to use, and those things don't happen.

monster you are amazing! I reset the PMU and it now starts. Why did the PMU need to be reset? Thanks again! |

Glad I could help out.
The PMU is the "Power Management Unit", It is actually on a chip that is usually on the logic board.
as it's name implies, it handles power management.
It can monitor the battery level (sometimes it loses track of the battery level, thus it thinks the battery is dead and you can't start up)
it can put the laptop to sleep, and set varying levels of power consumption
it also controls backlighting, HD spin down, charging, trackpad controls and some input/output relating to...computer sleep.
Over time the settings may become unusable, like when a laptop is left setting to long in a closet.
When a PMU reset is done it will return the laptop hardware and NVRAM to it's default settings, resetting the PMU on any PowerBook or iBook will permanently remove a RAM disk, if present, and all of its contents.
Now...everything I mentioned can be found in this Apple document, http://docs.info.apple.com/article.html?artnum=14449
and if you scroll down you can find out how to reset the PMU and/or PRAM for other Apple laptops too. Just in case others may need the info.
