Hi, I'm having some issues with charging my Lenovo ThinkPad 11E. When it is plugged in, it doesn't charge:
$ acpi -i
Battery 0: Unknown, 97%
Battery 0: design capacity 4151 mAh, last full capacity 3439 mAh = 82%
The battery level doesn't go up or down. I guess this means that the computer is using power from the AC adapter, but not using it to charge the battery.
When unplugged, it works as expected (except for being slightly optimistic about the remaining time, but it gets better after a minute or so).
$ acpi -i
Battery 0: Discharging, 97%, 10:11:27 remaining
Battery 0: design capacity 4185 mAh, last full capacity 3467 mAh = 82%
If I let it discharge for a bit and then plug it back in, it stays at the new level of charge, so I don't think it's a question of something misreporting the maximum capacity for the battery.
I have gotten the computer to charge by booting Lubuntu from a live usb, unplugging and plugging in the computer a few times until it starts charging, and then rebooting back into Arch. I would prefer not to do this every time my computer needs charging
Up until two days ago, I was running Ubuntu on this computer, and charging worked fine, so if it is a hardware failure it coincided perfectly with installing Arch.
Here is some stuff that could be useful.

Also, here is some output from dmesg.
This is my first time asking a question here, so let me know if there's any more information I could provide. I didn't know whether to post here or in the Newbie section; I hope this is OK. Thanks for any help!

OK, it seems like there wasn't a problem. If I let the battery discharge more and then plug the adapter in, it will start charging. That's good enough for me! It seems like a lot of people want this functionality, so I guess I should be happy.
