OK, I've seen this twice (so it isn't complete death) but wanted to see if anyone else had any ideas. I've done a complete shut down (power button for 8 sec) and then couldn't get it to turn back on. When this is happening, I can plug it in and see the green charging light. Holding the power button then for 8 sec will make the green light go out. Pushing it again, light comes on. So the button is working... If i leave it for awhile, the nook will then reboot and appear to work normally...

Rooted, stock, 2.0.5

If your device battery level is below 10 percent it will not turn on until it charges up to at leat 15 percent level. Then it will turn on.

I think that is the mechanism stopping it, but it is malfunctioning, I'm at about 90% this last time...

Is there ther equivalent of 'battery stats' somewhere that can be affecting this? or is this hardware? It should be turning on fine at 80-90% but no. However, plug in for 10 mins and it works fine. So that seems to be the problem.

OK, this is getting worse, I'm now at 100% charge and it happened. Weirder still, if I leave it plugged in for awhile, it will reboot on its own.

I have not had this happen on my HD but something similar has happened on my HD+. It seems to be related to whether an SD is plugged in. I have to take the SD out, press power off for a while, then release and momentarily press power again.

I know on the Nook Colors, they would not turn on unless it could find the boot files to boot from. So if a user formatted his internal boot partition by mistake, it would not turn on unless a bootable SD with active boot files was in the slot. Something akin to this may be happening, only in reverse.

Once I got it booting, then I could put the SD back in and boot to it.

(And your thread title says HD).

OK, this seems to have worked. I tried to change the partition of my CWM SD card using EaseUS, but that seemed to make it no bootable, and removing it does seem to have worked. Now I can boot a new reimaged CWM card.

Thanks!

Something similar happened to my HD+ running the 12/31 build of verygreen's CM. In my case, I think it was precipitated by the battery draining too far first, though. Very weird and a little spooky, but glad there's a workaround.

Wow, this is dumb. I can't believe a badly-formatted SD would cause it to look like it's broken. Put a message up or something. Thanks for the help, thought something was really wrong!

Nook HD Plus won't charge

I've seen dozens of reports of this. The symptoms are all about the same.
The unit drains the battery, even if you plug it in, it still drains, so although the charger and cable are fine, something inside the Nook doesn't get the memo.
It drains down to the point where it turns off. Then every time you plug it in, the light goes green, then amber, then off. The battery never charges.

I tried taking the unit apart and disconnecting the battery overnight, but that didn't seem to help. I suspect something in the software gets in a "vapor lock" where a dead battery condition is mistaken for a fully-charged battery condition. I only paid $109 for it refurbished, so it isn't worth another $60 for a new battery, and I don't think there is anything wrong with this battery.

If I knew the pinouts of the battery connector, I might try charging it without going through the Nook. Perhaps if it was actually fully charged, the "vapor" would realign.

Does anyone have another idea, apart from the nitwit stuff Barnes & Noble allows on its forums, like "push the cable in harder" or try another adapter. I notice they aren't interested in entertaining any idea that their firmware is at fault.

It will not charge when plugged in if OTG USB is activated (e.g., to connect a USB keyboard). That's happened to me a few times using unofficial VG CM versions where the USB state can be changed inadvertently from a pull down drawer. If the USB isn't toggled back to normal in time to recharge the battery before its completely discharged, it might not be revivable.

I've the same problem, except even if I leave it a while, it doesn't boot or even appear to start. Is there something wrong with the battery or display? It was working perfectly fine until suddenly the screen froze and I had to do a complete shut down.

I cant get my nook to turn on. I try charging it and a little green light comes on at the bottom and stays on for about 3 seconds and then a orange light comes on for about 3 seconds and then it shuts off. I dont know if the light is supposed to stay on while it is charging. Sometimes it comes up with a dead battery sign but it just goes right back off.

Have you tried charging it with its wall-charger for an extended period (8+ hours)?
