I have a Nook Color which I’ve modded with an SD card install of Cyanogen 7 to turn it into an Android tablet. Up til recently, whenever I switched off the screen (not turning it all the way off) it would just sit there for hours, not using up any power and turning right back on as soon as I clicked the button again.
Recently, I picked it up and found the battery had been completely drained, to the point where it wouldn’t power up at all until it had been plugged in for a good while. Since then, it has been acting oddly.
It no longer stays “sleeping” when I have the screen off; instead it turns itself completely off after a while. The time it takes to do this varies, and I haven’t seen any consistency to it that I can put my finger on. Sometimes it seems to wait hours and drain a lot of power before turning off, sometimes it seems to turn off almost immediately.
An even more disturbing thing it does is that when I do purposely turn it off, sometimes it doesn’t stay turned off! It turns itself back on and starts sucking power, or it sucks power even without being turned on at all.
I can’t figure out what’s happening, and I can’t find any proper power settings or “turn me off under these circumstances” settings to adjust, only the “what to do when the power reaches a selected percentage” settings, which don’t apply in this case.
I’ve tried taking out the SD card and it operates normally without it (as a plain Nook, of course), so it’s apparently not a problem with the device itself, but with the Cyanogen mod.
Wow, 283 views and no replies. That’s impressive. Is it safe to assume there aren’t a lot of Android experts on the board? My husband is now trying to deal with the SD card, which the device can no longer read. It looks like our only option at this point is to start over and reformat, repartition and reload the latest Cyanogen mod. And hope it stops mucking up.
Unless, of course, the card itself is defective, in which case bugger.
BetterBatteryStats in the Play Store. You’ve got some app or other preventing the tablet from going to sleep. Once you know what’s doing it, you can do something about it.
At this point it seems that the card itself is kaput, as it won’t even let us format it. So we’ll be starting over with a fresh card and see how that does. Thanks for the link to the Android forums.
If it’s any consolation, I have the same setup on my Nook Color and have been having several problems: battery drainage similar to the OP, plus occasional inability to boot (it just reboots and reboots). I had made backups of the SD card when things were working well, so I can restore it to fully working condition, but it always re-breaks within the week. It’s possible that the card has gone bad I guess.
I’ve just reverted to using the Nook as a Nook. I have lost my willingness to tinker with it for the meager privilege of installing apps and using Google Maps while in the bathroom.
I do miss being able to play Freecell on it, though. I hate how there are so few free apps from B&N. I guess that’s how they keep the Nook so cheap. It wouldn’t have been my first choice, but it was a gift from my dad, so beggars can’t be choosers. It’s not like I’d have been in the market to buy myself a tablet or e-reader anytime soon.
I also miss being able to access my Kindle books on it, though I suppose I can read them on my phone if it comes to that.
I had a Nook Color that I also turned into a full Android tablet, and I had better luck flashing the internal storage to run Cyanogen Mod naively rather than running off the SD card. I just found the SD card version was slower and had random problems/bugs.
Is it possible to revert it to Nook form after that, if necessary? As I’m in a country that doesn’t have a Barnes and Noble to take it to for any kinds of repairs or replacements, I’m not much bothered by warranty issues (and have already voided it anyway, by having to open the case to get the SD card out from between its slot and the case where it all too easily slipped). But if something happens to disable the internal mod, can it still be used as a Nook?
