Under sysvinit, everything “just works.” Under systemd as of November 2014, ACPI settings (such as what to do when the laptop lid is closed) and other aspects may not work as intended, if at all.
The T400 is excellent under sysvinit as of 2014, so any distros based on it should also work well. It may have problems under systemd-based distros from the same time period, however.
