I only use it to boot a rather tiny system, no GSM, no WiFi, but ssh and X are able to run. -- Damien Thebault ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
power-on without battery!
Hi, I was trying to power-on my FR but having the battery removed and didn't succeed! Goes up to a point and then stops! Is a reason for that? Thanks Tony ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: power-on without battery!
Sorry you are right! I forgot to mention that it was plugged in the USB port!

Re: power-on without battery!
I think you should be more concerned with the clips that hold the back cover on your phone. I only remove the cover (very carefully) when my phone freezes). It's also easier to find a new battery insted of finding a new back cover for the freerunner. depeje Op Tuesday 11 November 2008 11:13:26 schreef Tony Berth: On Tue, Nov 11, 2008 at 11:03 AM, Christian Adams [EMAIL PROTECTED] wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Am 11.11.2008 um 10:35 schrieb Tony Berth: Hi, I was trying to power-on my FR but having the battery removed and didn't succeed!

Also, one thing I find rather annoying: Why does the Freerunner have to power-on if I plug in the usb cable? (Given that other side of the cable is already connected to running computer) I'd prefer having to push the power button even in that case. If the reason is to negotiate more current for charging, I'd again point to 'the bootloader should do that and then send the phone to sleep'. :) Just my 2 cents. -- Tobias PGP: http://9ac7e0bc.uguu.de このメールは十割再利用されたビットで作られています。 ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Li-Ion and LiPo don't suffer from memory effect: http://www.batteryuniversity.com/partone-5A.htm Do not discharge lithium-ion too deeply. Instead, charge it frequently. Lithium-ion does not have memory problems like nickel-cadmium batteries. No deep discharges are needed for conditioning. -- Tobias PGP: http://9ac7e0bc.uguu.de このメールは十割再利用されたビットで作られています。 ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

IIRC at some points 500mA are too few to run the FR (there was some threads in kernel ML), that's why it can't boot using just the standard PC USB connection. It should work using the wall charger... -- Treviño's World - Life and Linux http://www.3v1n0.net/ ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I already have one of the little clips broken (bottom ones)... I will have to find a solution for when the second breaks... About battery, not only 100mA is not enough to boot, but even with 1A charger, it was stated that GSM module may require peak power up to about 2A, so battery cannot really be always out. About battery life, maybe the charge management code might also be tuned to be even more clever... (for example, a mode were battery life comes before charge speed). It should be possible to easily force slow charge even if wall charger is plugged in (1A is quite a lot for a battery). And maybe could use something like pulse charging... (I do not know what are -if any- the clever ways of charging this kind of battery) ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
