LEDs status

The only LED I ever really noticed on my Hima was the blue one telling me BT was on or off. I know the device has a green, yellow and red LED on the opposite side that can either burn or flash, but don't ask me why. Neither do I know if the flashing rate of the blue LED might tell me something.
Last week when my battery was just about 99.9% drained and my Hima started to behave strange, I noticed that on external power the red LED burned constantly. And when I notice something like that, it's probably because I've never seen it before.
http://michael-channon.spaces.live...._c=BlogPart&partqs=cat=Hermes+Charging+Issues helped me out.
But I would love to know the exact meaning of all LED colours and blinking rates.

all the Leds's Rate are in the Book that comes with it

Thanks, but as I told before I bought 2 Hima's with broken screens years ago, under those conditions it's very rare to get anything but the dead device itself.
The service manual only tells me that a fast flashing yellow LED means battery is too warm (>35C) or too cold (<0C) to charge.

hmmz..u r rite..its unpredictable..any way i'll see what i can find

What I can see, it's blinking green on normal operation, lighting yellow on charging, blinking red on missed calls and lighting red on too low voltage...

Mine never blinks green. Lighting green tells me charging reached 100%.
Could blinking green mean GPRS or IR on?
Anyone ever seen blinking yellow?
I hope curiosity only kills cats ;-)
I guessed the lighting red :-(

Mine blinking green when it is in normal operation.
Yellow on charging
Red when there is misscall or message because I set to give LED sign

> Green for normal - with carrier signal operation and Fully charged while still plugged into wallsocket
> Yellow for Charging
> Red - missed calls/poor elec current while being charged/very low battery
@Maggy, there is a tweak on how to permanently disable blinking lite even during normal operation. could it be possible that ur units have are tweaked like such?

Not that I can remember, but I'm tweaking all the time. Aren't we all?
;-)

how come on my XDA my colors are
Yellow=Normal Operation
ORANGE=Charging
Red=Low batt

May be your led is expired Yellow and Orange is slighly different, you lose green color I think every body mentioned yellow in here is little bit mix with orange color

Or some of us are more colour blind than others

New battery

I have gotten myself a new battery but the battery is only 52% and the LED light is not Red meaning it has finished charging. How do I calibrate my new battery?
Update:
As I am charging, I noticed that the percentage keeps going down. From 64% to 53% now. What's wrong?

just because your led is not red doesn't mean it's finished charging. it's finished charging when the led is green. (well, it's green when it gets to 90% charged, but you get my point)

The led is red and from the notification, it shows as charging, but my battery life is depleting, asking me now to connect to charger. You get what I mean?

it might be your charger. have you tried using a different one?

To recalibrate I do:
1.Wipe batt stats
2.Let new batt die out fully
3.Recharge till 100% by looking @ lock screen or spare parts
*I've only used wipe batt when using diff rom.

As in the previous battery works fine, I can charge with it. But this new battery doesnt seem to charge although it says in the notification that it is charging...

Same issue not solution

tytn 2 not charging

hi!
i was just wondering, my tytn 2 is not charging, when i look at the battery meter, it says charging, but instead of going up. it goes down, the amber light
the signals charging is gone.
im sure its not the battery. coz i did get a charger, the one where u put probes on the + and - terminal of the battery, it charged. the battery is working now. however, i couldnt charge via the phone.
the red light came up before which indicates not charging so what do i do now?
someone suggested to hard reset it. i tried it but nothing. still the same. i reflashed it... nothing... now using the hyperdragon rom... still the same...
any ideas?

btw, when i plug in the charger, amber light is there... however, not for long, light turns off, but the charging / plugged into the charger symbol is there

as far as my personal experience goes, i have noticed this behavior only when the battery overheats while charging. in the hottest weather, this has NEVER happened for me. it only happens sometimes if my device screen is on WITH wifi WITH bluetooth WITH data connection WITH some heavy processing program running. this causes heating of the components and also leaves little power to charge the battery, because most of the charger's power is being redirected to power the components in use.
so, the device will charge for a few minutes and will interrupt the charging if the temperature rises. the charging will resume again when the temperature comes back down.
you can test if this is happening with your device by observing how long it charges before stopping, first without a fan and then with a fan blowing over the battery with the back cover removed.
if the charging lasts longer when the device is being cooled with a fan, then you are likely facing temperature issues.

Try to clean your battery terminals and see if that can help... http://forum.xda-developers.com/showthread.php?t=358136

Your same issue

solved my problem...
i was so pissed, all the solutions did not work... i decided to open it up
when i opened it, i saw that there is some dirt / corrosion on some lines
cleaned each and every one of them.
while it was open, plugged in the battery... then the charger...
after 2 minutes... battery bar went up! it is now charging!!! and
best thing... it also syncs!

Good to know that you solved your problem.

Battery does not charge over 50%

The battery of my Nook Color (CM7 - build 128) does not charge over 50%.
The battery completely drained out (I probably left it on standby for 1 week) and now when I recharge it the charge level always stops exactly at 50% (shown on Spare Parts). I also noticed that when the charge level reaches 50%, the color of the 'n' symbol on the USB cable becomes green (maybe it thinks that 50% is now the maximum charge level?)
Can someone help?
Thanks!

If you have cwm installed, go to advanced option and reset battery stats. Then reboot and charge your nook. Looks like the complete drain might have screwed up the reporting on charge. I would recommend charging the nook while it is turned off and see if that fixes the problem.

Are you using the B&N Nook Cable and charger?

I do not have cwm installed. Is there another way to reset the battery stats?
I tried to charge the nook when it is off, but it automatically powers itself on anytime I connect the USB cable. I do not remember it behaving like this before.

Good. So i see you're using build 128, you might try updating that. I don't recall when some of the battery calibration problems were fixed.
One thing to be clear on is even if your NC is saying it's 50%, if the charger stops, the battery is full. The charging is independent of Android, so it's not like it's overcharging etc. Most likely it's a calibration issue.
Get up to date on CM7 and use the NC until it powers off on its own then plug it in and don't touch it. It will turn on by itself. Leave it alone until it's done charging, see where it is then.

[SOLVE REQUEST] The issue with the battery charging indicator of Nook Color

Recently acquired certified pre-owned Nook Color, but there is a issue: at any level of the battery charging, the green light is lit on the cord, although it should be orange if the battery is not fully charged. While charging is normal (~ 3 hours 15-100%). In what could be the problem? Very uncomfortable, because is not visible when the device is fully charged.
Previously, I had another NC, which worked fine.
Maybe someone else had this problem? How to solve it? Really need help.
Thanks in advance.

Is this with stock B&N ROM? If not stock, which ROM are you using... some, myself included, have seen carging issues with certain configurations, although I cannot say specifically that my configuration is not causing the issue I see,

In normal charging operation the light is orange until fully charged then turns green. In CM7 the led would turn green and stay green all the time when Host mode (otg) is activated using Nook Tweaks even when charging. In CM9/10 host mode is activated by default. Root hub is present and host mode is active but the encore otg module is not installed, thus we don't have USB otg yet. So, in a nutshell, having the green led on all the time doesn't indicate anything wrong with the charger/cable. I just charge it overnight or plug it in when it gets to 15 percent when the warning sounds the low battery alarm and unplug it when the lock screen indicated 100% charged.
Edit: If CM10 host mode is not activated by default the setting is a remnant of CM7 Nook Tweaks host mode setting.
Update: Tested the charger/cable from my other Nook with CM7 - light is orange when charging, green when fully charge on CM7. Tested same charger/cable on Nook with CM10- light stays green during charging.
Update 12/28/12: Had to get a new charging cable today $14.95 plus tax. The micro pins bent and broke when nook fell off table while charging.
The new cable now shows orange when charging. So issue may well be a bad cable after all. New cable shows green when fully charged.

I had the same problem with my Nook Color and it turned out being the cable. If you have noticed, the configuration of the micro USB connector is different than what you see with say a Motorola Droid. This makes the cable a little more difficult to get plugged in and can cause some damage to the pin arrangement if forced. I called B&N and complained and they sent me a new cable free of charge. I keep the old cable as a spare as it works well other than the indicator.
As a side note, I have used various versions including stock, rooted stock, CM7, and CM10 and the problem appeared to be independent of the ROM being used.

I just got a new cable and the indicator stays orange when fully charged. My old cable still works fine (orange while charging, green when charged), but the plastic at the micro-USB end is splitting apart. I have a piece of clear tape holding it together.
I guess as long as they keep actually charging the device, I can't complain too much.
ETA: On stock rom you can still see if it's charged by unlocking and tapping the lower right corner where the battery icon is. The Quick Settings pop up and show % charged.
