How to turn off hibernation mode

Dormancy (Hibernate)

After switching the system to this mode, the system will automatically transfer all the data in memory to a dormant file on the hard drive, and then cut off the power to all devices. In this way, when restoring, the system will read the contents of the dormant file directly into memory from the hard disk and return to the state before hibernation. This mode does not consume power at all, so it is not afraid of abnormal power supply after hibernation, but at the cost of a hard disk space as large as physical memory (fortunately, hard drives are now beyond the TB level, and high-capacity hard drives are getting cheaper and cheaper). The recovery speed of this mode is slow, depending on the memory size and hard disk speed, which usually takes about 1 minute or more.

Sleep (Sleep)

Is a new mode in Windows Vista that combines all the advantages of standby and hibernation. After switching the system to sleep, the system transfers all the data in memory to a hibernation file on the hard disk (which is similar to hibernation), and then turns off the power to all devices except memory. Keep the data in memory still (which is similar to standby). In this way, when we want to recover, if the power supply is not abnormal during sleep, we can recover directly from the data in memory (similar to standby), which is very fast; but if the power supply is abnormal during sleep, the data in memory has been lost and can be recovered from the hard disk (similar to hibernation), but the speed will be slower. But in any case, this mode will not result in data loss.
