Cool, at least it is supported. I know someone with that got a brand new |
| 34 |
Lenovo about a year ago and had loads of issues with it, even with the |
| 35 |
bleeding edge kernels in Arch. |

Do you have SUSPEND=y (just checking)? Other things that I can |
| 42 |
see related to suspend are SUSPEND_FREEZER, ACPI_SLEEP, |
| 43 |
APM_IGNORE_USER_SUSPEND, and a bunch of Thinkpad/Lenovo related options. |
| 44 |
I do not have suspend enabled on my laptop, so take this with a grain of |
| 45 |
salt. |

If you want to search various kernel options, you can run `make |
| 48 |
menuconfig` in the source directory and use '/' (forward slash) to |
| 49 |
search just like you're in `less'. |
