Classic Power Issue all of a sudden

jhempel24 · 11-19-2010, 09:31 AM

I've got a rooted Nook, and I've had it since August, and over the past few days I've noticed that I can plug it in and do a full charge...and the next day I get low power and I'm only reading for say 2-3 hours intermittently.

I've got the Airplane Mode on, my color screen set to go dark at 10 seconds.

I've got a screen saver, so Im going to disable that....if eInk doesn't burn in, I guess I don't see the point, but will gt something to see when it goes to sleep.

there has to something downloaded in the root that is draining the battery source.

is it still running Trook? you have to manually exit that program or its known to drain battery. also in wifi locker, some people have disabled ADB to help.

Thanks guys.....I don't know how to "close" trook other than pressing the "n" to go back to the home screen.

Other than that, I haven't disabled ADB, what would that do? I remember something about it, but it has slipped my mind as to what exactly.

I called B&N, and they had me just discharge the Nook, and the plug it in again and let it sit for 4 hours before powering it on, if it doesn't work, call back Monday and they'll send a battery out.

in trook, go to the settings icon and there's an option to exit trook

I guess having ADB enabled also drains the battery, so it might help. It's only useful to have enabled when you're using ADB afaik.

I had the same problem and I found an interesting oddity. When I had WiFi Locker on a WiFi model with all the power options turned off, there was no power loss. When I had the same app on a 3G model, it sucked th epower totally in 16 hours. I have since uninstalled WiFi Locker and, so far, the 3G model seems to be holding the charge.

I think Locker is the problem. I had a power loss, I removed Trook and Locker, no power problem. I reinstalled Locker, problem returns. Remove Locker, problem gone.

I would guess it is overriding airplane mode and trying to active WiFi even when it is not active.

Hmm....that's pretty interesting, but I have a problem with my Wi-Fi staying connected, so I lock it when I turn my Wi-Fi on.....if I knew what ADB did, and when I would need to use it, I would turn it off and only turn it on when I needed it.

Any thoughts from anyone on the ADB?

As I understand it, "ADB, or Android Debug Bridge, is a versatile tool lets you manage the state of an emulator instance or Android-powered device."

In other words, it allows communication with our nook at basic levels. I think you would only need it on when issuing commands, or adding or deleting apps.
