Drained battery

[sparkymat]

I am attempting to switch on my Freerunner after quite a few months. However, it just doesn't turn on.

I was trying some suggestions from the following page: http://wiki.openmoko.org/wiki/Freerunner_Hardware_Issues#Can.27t_boot_with_discharged_or_missing_battery_.28FIXED.29 . I have the external charger, I tried booting into the AUX menu, tried booting with USB power. Nothing worked. Any suggestions other than getting a new battery?  :-)

Read and try "ALL" the suggestions listed on the wiki - they do work!

remove battery for 30 seconds and replace.
Leave it overnight on the wall charger
remove battery for 30 seconds and replace.
Ive found that removing the battery briefly and allow the undercharge
cutoff to reset (maybe bad terminiology?).  Without this, Ive found that
the phone often fails to charge/start if the battery is completely flat.

Use a nokia battery as listed on the wiki (borrow one - they are really
common) to jump start it as per the instructions on the wiki - this
should always start the phone if its ok, then swap batteries and see how
yours charges.

Once up, make sure you have a recent u-boot or Qi - some of the earlier
phones had versions that made starting with a flat battery more
difficult that it needed to be.

I dont think its mentioned in the wiki, but when booting via USB power
you need to use the USB cable supplied with the openmoko.

If you have another USB cable it wont supply enough power to allow it
to boot, USB cables have some sort of id built in which is required to
allow a higher current than the USB spec specifies to be supplied.

With the USB cable supplied it should be able to boot without the
battery.

I managed to get hold of a BL-5C battery, and now everything's fine. :-)

Btw,

for the list of phones sporting this battery.

I think you have it rather mixed up.  These are standard usb cables -
any one with the right connector is ok.  The wall charger, which uses a
usb connector on one end (its NOT a proper usb cable as its for power
only), has a resister connected between two pins to tell the FR that its
capable of supplying 1A.  The usb data cables supplied are standard.

Early hardware (GTA02A5?) - cannot supply enough current to boot from
USB.  The mods were both software (u-boot and then Qi) to stagger the
startup inrush of current as various parts were powered up (hence make
sure you upgrade u-boot or Qi) and add extra capacitance so the voltage
doesnt dip as far power is applied.

I cant point you to a reference for this, but I am sure one of those
involved will jump in (or on me :) if I have got it wrong.

Hi, maybe you can try using other battery to turn on your Freerunner and check if every thing is fine with the phone, I did it few months ago when I tried to charge my freerunner but wasn't able to do that 'cause at that time my 120v power extension cable was defective and did not let pass electricity to the Freerunner's charger. And I thought that my battery was dead or my phone is damage. So I used my BL-5c 3.7v battery from my Nokia on the Freerunner to turn it on, and it worked 'cause the two batteries supplies the same energy. (Now I know that my Freerunner and the battery are fine, and was may cable the defective one).

Maybe what you need to do is find any battery like it (BL-5c 3.7v), turn on your Freerunner with it, and when it finished to start up, with the charger or USB cable pluged in to the Freerunner, change the battery to the original that came with the Freerunner, and see if the battery accepts or receive charge (the charger or the USB pluged in while you change the batteries allows that the phone doesn't turn off). And if it works, let the battery charge more than the necessary time.

Please take in mind that this battery is not designed for the Freerunner, but supplies the same energy required for the Freerunner, but not the necesary to make phone calls, at least for me tested on the om2009. But for me it doesn't affected my Freerunner in any way.


Hope this helps.

Adrian Carrera.
