    When I put my T400 to sleep, it can "instantly" wake up (it only wakes up if I press the power button). However, if I leave it over night and then I try to wake it up, it's not instant. I see the "resuming windows" screen and initialization of the BIOS etc.

    Anyway I can enable instant wakeup for long hours?

    S3 is standby or STR (Suspend to RAM). This is effectively instant resume.

    S4 is hibernate or STD (Suspend to Disk). This requires reading the contents of your RAM back from your HDD (can take a minute or more) before resuming.

    You can go into power properties and tell your ThinkPad to never hibernate, or you can disable hibernate with this command.
