Sleep and hibernate are just two of about a half-dozen power states that are defined in Windows. More than you wanted to know can be found at https://www.tenforums.com …e-your-windows-10-pc.html
. A key pitfall of hibernate is it writes to disk, the entire image of what may in RAM. That is why file space of 75% of RAM is reserved. Its a file named hiberfil.sys and is typically hidden. The continual writing to disk, when that disk is an SSD, is not recommended. “Sleep” retains the last working state in RAM (as opposed to disk) so only a small amount of power is used. Some people feel that with an SSD shutdown should be used as opposed to sleep to save energy. The reality is if your desktop uses 10 watts in sleep, it costs you less than a dime if left in standby for 24 hours. Since SSD’s are so fast on a cold start, I get my login screen in about 10 seconds, it is a good idea to power off for extended periods. With old spinning platter HDD’s it was felt that the startup of the drive was undesirable, hence te need for sleep and hibernate.
