How is the power management? I run a linux (ubuntu) thinkpad for work, and while I find the OS pleasant to use, I have found the battery life dire compared to windows-using colleagues.
- cheald 15y agoMy understanding is that much of this is due to regressions in the kernel. Some of the more recent 3.2 kernels are supposed to fix it.
- jsvaughan 15y agoI run ubuntu 11.10 on a thinkpad and I find that battery life is on a par with Windows. You might want to investigate the ASPM power regression issue; pcie_aspm=force might work for you (or wait for ubuntu 12.04 which cw the 3.2 kernel containing the fix)
- AlisdairO 15y agoThanks, I'll give it a try.
