Has anyone tried using a light for the nook that is powered by the micro USB port?
I haven't found any USB lights with micro USB connectors, but was tempted to buy a laptop USB light and swapping the connector for a micro USB connector.
Plug it into your nook touch and you have light. Of course this will drain your nooks battery faster, but I would hate to have to worry about charging batteries on a reading light in addition to ensuring my nook is charged.
It may be possible, just check if the power drain is not very high, as the USB has a limit of 500 mA (if I am not mistaken). If it works, please tell us.
You will need the USB hack that is on the forum, but I guess there is nothing that would prevent it to work (just maybe frying your USB connection).
Good luck.
You should be able to draw some decent current off the USB connector.
I've pulled >100mA trying to power a hub.
I don't know how much current those LEDs pull but certainly less than that.
It's unfortunate that 2.1 doesn't support reverse portrait or you could have the light at the top!
Light working
Hi. I saw this thread and then I've remembered that I should have an old laptop light so I gave it a go

Nice....I just ordered a plug on amazon at the moment to do basically the same thing. I've got an old light at home that still works.
Plug: http://amzn.com/B005FUNYSA
Have you used it any with the light? How does the battery handle it?
I'm tempted to sell my current Nook Touch and get the one just announced: Nook Simple Touch with Glowlight, IF the Nook powered light isn't great.
Edit: I received the plug, however the light i have doesn't seem to light up off of it. I checked to see that it works off of a USB port on my computer, so I'm not sure if it just wants too much juice or what. I wonder if I need to be rooted, to allow it to work (doubtful, but not sure)...
hello guys
when i charge my nook with nook's charger ..... the charger become too hot till i feel that my usb connector gonna melt ...... i dont know why .... anyone expert in hardware staff???
thx
Do you have another micro-USB charger you can try? The NST doesn't need the official Nook charger. I've been using my phone's charger with no problems for months.
If another charger also heats up, then I'd worry about your Nook. If not, then I'd worry about your Nook charger.

can u specific me an charger ,,,,, thx
Any charger with a micro-USB plug will work. Here's a generic one from Amazon.
Any standard micro USB to USB cable will charge your nook device. Most power transformers that have a USB output will work, also - I charge my nook off of whatever's to hand. My memory is that the NST chargers are 1 amp or so, but if they don't have access to that much current, the NST will charge a bit slower.
Also, you can use your computer's USB port to charge a nook touch (or a nook color/tablet, but the latter two will charge very slowly that way)
If there's really a problem with the device, rather than the charger, that might make trouble -it wouldn't be the first thing to recommend since it could make trouble for your USB port or your PC as a whole.
Some warming of those transformers is fairly normal, though - I see it with my phone and with my LCD nooks, moreso when they are mostly discharged before I start charging them.
Something is wrong there. Nothing should be getting hot to the touch.
As previously said, try another charger or a USB cable connected to a computer.
Is your Nook still charging correctly? Does it get to 100%?
You can look at the battery actual voltage a few different ways.
UsbMode can show you, so can this command in ADB:
Code:
am start -n com.android.settings/.BatteryInfo

u r right .... nook charger is about 1 Amp consumption .... also it's charge nook too fast .... between i charge nook from computer it's become too slow also take about 4 hours or more to become 100% , and the thing make me sure that nook charge till the led turn from orange to green

To prevent your Nook from mounting as a Mass Storage Device when you plug it into a PC, do this:

New to this ROM, is it a normal thing for the nook not to charge while on? I have to power off for the nook to charge up. Any ideas or just a normal side affect of using the ROM? Thanks!
I charge while it is sleeping.. no problem..
whats weird is a usb cable to computer charges it but not the original nook charger, only when I power off the device. I guess its not a huge inconvenience though it would be nice to charge with the wall charger.

And using original cable, not just a micro usb cable?

yes stock cable and wall plug. It wont charge while nook is on, but as soon as I power off the nook, the cable turns orange and charges just fine. If I power it back up, cable turns green like its all charged. If I use a regular usb cable while its on, it shows charging (USB). I have a new nook charger and cable coming from B&N so will see if that fixes the issue. But this cable was charging stock nook color fine, so I think its something else.

I don't think the replacement is going to fix the problem either.
I have seen this issue with CM10 on EMMC... I THINK my issue is due to multiboot from SD... Here's why... and I will do more investigating...
1. When booted to CM10 light is immediately green and nook shows discharging even when plugged in.
2. When booted to CM7 it works correctly... unless....
3. If I set deault boot to EMMC/Normal... No matter what boot i choose... immediate green light and no charging unless powered off... or sitting at the CyanoBoot menu
4. When attached to USB car charger... both indicate and charge normal.
I will do some more testing and investigation... like changing CM7 and CM10 install locations and performing above tests again and see if can narrow down the cause.
I have an SD card in the nook but its just for storage. So you think its a ROM issue with CM10? I put it on the charger last night and this morning it was at 39%, I just reconnected it and its orange again so I will see what happens.
so I installed the latest CM10 nightly and the nook at the moment is charging while turned on. How often is PA synced with the CM10 nightlies? I will do some more testing to make sure its not a fluke and falsely charging.
now its not charging while powered on LOL. Almost wondering if its the cable since the tip kind of moves a little bit. Powered off it does charge fine though. Weird.

Synced with the day of the build...there is nothing charge related in the PA framework so you should see identical behavior in CM nightlies, all things being equal.
so it must be a CM issue? I suppose I could go back to stock and see if it works there. the latest PA I see is from Nov 21 or am I looking in the wrong place? I just dont know why the thing charges perfectly fine with the device off, but doesnt charge correctly while powered on. I have to plug in a standard microusb cable which charges it while powered on.
It wouldn't be strictly a CM10 issue or others running the same ROM would be seeing the same problem.. I am not..
ok I am awaiting the brand new charger setup from B&N to arrive and will see if that fixes things. I tried CM10 based roms and CM7 based roms and the same thing occurs so it might be a bad cable. CM10 seems more responsive than PA, which I know is based on CM10.
I restored to stock 1.4.3 and the cable is charging just fine while powered on. I am going to redo the rooting and see if maybe I might have missed something on the install.
Seems a bit odd but my Nexus 7 (1st Gen) will not charge when connected to a USB wall outlet. But it has no issues charging when connected to a desktop/laptop.
The following I have tried:
- I have rebooted, shutdown, booted into the boot loader and shutdown/rebooted from it into the OS
- I have tried several USB wall power adapter range in amps output from 0.7 to 2.0.
----Also tried 4 different USB cables with the USB wall power adapter.
-Enabled/disabled developer mode along with USB debugging mode
-Tried charging the unit when it is OFF and ON, only charges when connected to a USB port on a desktop/laptop
-Removed the back cover to see if the USB port could be loose, looks and feels securely in place
Not sure if it could be a software issue, unit is running 4.3 build number JWR66Y. I am hoping to avoid resetting the unit but if I have to I will.
Thoughts anyone?
Is your device rooted? If yes, then try to change the ROM (make a nandroid first).

I would say if your rooted and cutomed and all that try a different kernel before a whole new rom. Kangaroo kernel first page of dev page is good.
Mine gets stuck sometimes. I installed battery monitor widget to see the actual current flow when charging. Even though it shows ac connected the graph can remain flat with no charge. Replugging the cord a few times gets it going. A charge only USB cord might help, but I've gotten the best amperage with the included cable so far.
I have a serious issue with my Nexus 7 2012. I put CM11 on it and all was great. The power got down to 11% on me, so I plugged it into my computer. I noticed it wasn’t charging, MTP didn’t kick in, and I couldn't get into ADB. I figured I’d screwed up the USB port. I tried different cables all with the same results. I turned the tablet off and plugged it in and the battery started charging. I couldn’t get MTP or PTP to work nor could I get into ADB after it was charged. I did a factory reset, clearing everything, and reinstalled. Same issue.
I can use my OTG cable and TWRP to install software on the tablet. I tried AKOP ROM. It allows me to use my OTG cable but the tablet doesn’t charge. I try to toggle MTP to PTP or turn off USB debugging and the tablet locks and reboots. I try to turn off the developer options toggle and the tablet locks and restarts.
Help! I don’t know what to do with it. I've searched all day.
Check the basics. When you plug your N7 into your computer, are you using a USB 2.0 port? Is it directly mounted on the computer's motherboard (i.e., a rear port)? Are the proper drivers installed so your N7 is recognized as a Nexus 7?
USB specifications only provide .5A power, v. 2.0A power from the AC charger. Get your N7 fully charged,then get back with whether it locks and reboots.

Thanks for the reply. Yes. I've done all of that. Multiple computers, multiple cables, multiple chargers. The Nexus is at 100%.
Here's the exact issue I have now: http://forum.xda-developers.com/showthread.php?t=2536272
Well. I'm going to say disregard. My searches show that a craptastic 12 volt car charger probably hosed the N7's mother board. I'm going to try one more fix but I'm sure it's toast.
