I second this question. It will become increasingly important as the
years go on.
I notice there is a plethora of different batteries on eBay for every type
of laptop imaginable, seemingly all unbranded and coming from unknown
Chinese factories. I wonder how difficult it would be to find a
manufacturer who will produce new batteries for the GTA0{1,2,4}.
Mr Pulster, Mr Schaller have either of you looked into this by any chance?

I have one battery that is very dead an two that are getting old and have to be recharged more often. I doubt they're still being made, but you can probably get a definitive answer from Pulster or GoldenDelicious. The SANYO UF653450S they contain still seems to be available, so sticking the controller board on a new cell should be possible. Of course they could be old stock too. My reading of the BQ27000 datasheet is that it'll get a power-on-reset when the new cell is attached, and should then learn the new cell capacity. I may have missed something important though. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

is my GTA02 getting old?
Hi all I have a GTA02A7, one of those with the buzz (not bass) fix. In the last months things got worse, the buzz fix seems not be any more effective. In particular, during a conversation, there are intermittent background noises, and they become louder and persistent when the GSM signal is low and/or when the battery level is low. Also, it's impossible to me to use the earphones, if I plug them the noises are so loud that I can't even hold a call. Add to this some strange GSM/modem behaviour: whenever I get low GSM signal for certain time, I have to restart the Neo because I loose the phone functionalities (cannot send/receive calls and messages), I don't know why. It happens some times in the underground (metro) and often in trains (once I was doing a long trip, I had to restart the Neo four (4!!) times during it). To date, with some patience, I use my GTA02 as a daily phone but I'm worrying if things get worse. Do you think that is possible to do some hardware check/fix? ..sure I'll not be able to do it, I'm in Italy if someone can help.

In the last months things got worse, the buzz fix seems not be any more effective. After my phone was buzz-fixed, one of the solder connections got loose. A friend of mine (with a steady hand...) re-soldered it, and it was OK again after that. So, open up your GTA02, take a good magnifying glass, and check the connections!
