I have a Lenovo Y560 and have installed Ubuntu 11.04 (64 bit) via Wubi. When I start the notebook on battery, Ubuntu hangs before the login screen. Any workarounds?
I have the Y560 as well and am experiencing the same problem. I tried downgrading to older kernels but still have the same issue. I did find this bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/775950 and verified that I have the same kernel panic and message happening. There is also someone with a Y460 with the same problem here Lenovo Y460 won't boot most of the time unless plugged in
Update 2011-07-16: It appears that the latest kernel update (2.6.38-10-generic) has fixed the issue on the Y560.
