On the Dell Venue 8 Pro, an Intel Bay Trail-based tablet device, with all kernels tested so far (3.11 through 3.14rc2), there is no kind of power status information - no battery stats, no indication of whether the device is on AC or battery. upower doesn't have any kind of info at all, it doesn't know there is a battery - it's pretty clear the kernel layer isn't providing any information.
I'm using Fedora Rawhide kernels with appropriate patches to actually boot on these devices, but I believe everyone using one of these Bay Trail tablets with whatever distro / kernel - the V8P, Lenovo Miix2, Asus T100 etc - has seen the same.
I'll attach boot logs and acpidump from the V8P in a few hours (building a new kernel ATM).
I think this bug is as same as bug 69011. Please have a check.
ah, yup, looks like it. others on the Secret Baytrail Cabal CC list didn't know of that bug, it seems. Thanks.
Jan-Michael Brummer is working on this, so you may want to co-ordinate with him - "We can already talk to the battery and receive some status information, but again this will need a proper patch."
