I have a G4 1GHz titanium laptop and recently have been using it heavily to VNC into 4 linux servers simulatenously running some heavy applications for CAD and CAM, the titanium laptop is fantastic, super fast in VNC mode (as all the processing is done by other machines) but has one issue its not portable as the battery pack died about 4 or 5 yrs ago.
So I have just purchased a chinese branded pack for $26 and it worked but has an intermittant fault were the power (from the battery pack when disconeected from the mains power) just vanishes (batteries are fully charged) and switches off which kills everything as the mains is not plugged in. I though the problem was with the low grade chinese terminal connector onthe battery pack so decided to open the battery pack and utilise the 8 x lion cells form the chinese pack to replace the 8 dead cells in the genuine battery pack, by the way the electronic circuit boards in the non geninuine battery pack are completely different to the geninunie battery pack whihc also has sensors that the chinese one doesn't.
So the revitalised battery pack has the following issues
- displays 0% when the power cord is plugged in, power cord does change to amber (green when no battery pack is present)
- but then after 10 mins the battery symbol changes to X )no battery available)
I have tried a PMU rest with no luck.
Could it be the internal resistance of the lion cells from the chinese battery pack is different to the internal resistance of the geninuine sony cells that were in the case and this will prevent correct operation. Yet it kinda worked when I first plugged the chinese battery pack before embarking on soldering adventures as it showed 100% and then decreased after an hour to 84% not before killing power and requiring a reboot 2 or 3 times.
In an nutshell is there a way to get a new battery pack for these machines that work, or do you know of some tips that can solve the issue.
I also note int he geniniune pack there were two temp style probes, maybe these are trigger as the temperature is different?
Any thoughts would be appreciated.
