The battery charge light is tied to whether the charge circuit is still pumping energy into the battery.
By nature of lipo batteries (unlike other batteries which could handle a steady trickle charge), it apparently should stop charging shortly after reaching full. So yes, the charge light should go out. Not going out means it is dumping energy into a full battery and that can lead to puffing. I'm still researching this, trying to collect more data on how to make it behave better.
who said i was normal ??That's not normal. On the right are two LEDs, one green, one red. The red one is the charge indicator. When it is on, it is charging. When it is off, it has finished charging and is discharging, or is not plugged in.
The far right one is the power LED. It is green. When it is bright green it is in normal operation, full speed, etc... When it is dim (which, with the red LED beside it, you may be confusing for amber) it is in low power mode. Unless you've done something to the LED controls, it's probably not doing what you think it's doing.
Mine never goes out just changes from amber to green when it is charged ; on the right one light is red & the other is amber . Then when fully charged it is red & green.
i see now how color blind i was.Mine never goes out just changes from amber to green when it is charged ; on the right one light is red & the other is amber . Then when fully charged it is red & green.
No, you're mistaking the low-power (dim) green + charging red for a red and an amber light. 1 Red + 0.5 green = amber (the adative properties of colored light). Unplug the charger, and you'll see that the power light is dim green.
Red and green is when it's charging and on.

I'm not sure it is TIED to the charge circuit. It's initialized with the kernel, and I'm not sure if it is on if the software THINKS the unit charges or only if the hardware REALLY does charge it.
There are multiple protection circuits to prevent overcharging - one in the battery AFAIR and also the TI Charger chip should stop.

My red light stays on all night, even when the status reports 100% charged. I'm now no longer using my Pandora until this is fixed - I don't want it to blow up. I've re-seated the battery multiple times. Please fix this ASAP.
No, it is tied to the charge circuit. An end-of-charge interrupt sent by the TWL is what turns it off, and a restarted-charging interrupt is what turns it back on.I'm not sure it is TIED to the charge circuit.

For LiCoO formulation batteries yes, for BEST life only to 90%
LiPo are LiCoO batteries (Co=cobalt, over 50% lithium bats are this formulation)
You can see all details at rcgroups.com , the modelers have been using LiPo for ~5 years,
all the failure modes have been discovered. When a ~$5000 model catches fire, or runs out of power
200 m short of a safe landing, the owner tends to be some annoyed. (or when the car catches fire from charging in trunk!!)
The best answer would be something that does not exist, a BT controlled line switch
(to turn charger on and off), and a cron job to check SOC (state of charge),
and then, depending on user selected parameters, turn charger on or off
If something like this does exist, please speak up

I was going to add some kind of gui, but I've had no feedback so if people are using it I assume its fine
as it is...
> I've halted all my Pandora work - I'm not even turning it on
http://chrisc.bedroomcoders.co.uk/?p=77 leave this running while in low power mode and the machine will power
off once charged, even when its connected to the mains - this is fine for the charger, it doesn't even get warm.
For those that have batteries that don't trip the charged status, WizardStan made a little app to temporarily
alter the threshold, I've tested both working together and it works fine...
End result is a fully charged Pandora in the morning (I leave charging over night usually) that hasn't
been baking its battery all night (if you have one of the few that don't trigger charged status)
