这个不对吧。Lenovo说c226不支持S1 standby,但这不等于不能sleep. sleeping state有下面这4个level (from Wikipedia). 很多机器不支持S1 -- older machines are more likely to support S1 than S3. S1, Power on Suspend (POS): All the processor caches are flushed, and the CPU(s) stops executing instructions. The power to the CPU(s) and RAM is maintained. Devices that do not indicate they must remain on, may be powered off. S2: CPU powered off. Dirty cache is flushed to RAM. S3, commonly referred to as Standby, Sleep, or Suspend to RAM (STR): RAM remains powered. S4, Hibernation or Suspend to Disk: All content of the main memory is saved to non-volatile memory such as a hard drive, and is powered down.
