Windows 10: How can I prevent laptop from going to sleep/hibernating?

I need to run a program, unattended, for a number of hours. Despite attempts to keep the computer awake using a new Power Profile, after 15 minutes the computer either goes to sleep or hibernates. What can I do to keep my computer awake? Why are settings ignored in the Power Profile?This occurs using a new Power Profile in which 'Turn off display' is set to 'Never' and 'Put the computer to sleep' is set to "Never." These settings are applied to both 'On battery' and 'Plugged in.' The problem persists after changing combinations of Settings/System/Power & Battery/Power mode settings

sleep or hibernate

sleep and hibernate are the same thing now.


S3 'sleep' has the entire system powered off, EXCEPT for system ram. a copy of ram is stored on the HDD when entering sleep.
To answer the OP's question about the HDD taking wear and tear moving the laptop around - in sleep mode, it is powered off. ONLY system RAM has power in S3 sleep states.

Hibernate is when it loses power, it boots from the saved copy of ram. Often, this can load slower than a fresh boot since it has to load more from the HDD than usual.


so asking which you prefer... well, unless its a laptop you plan to store overnight or something, use sleep. its the same thing.

S3 sleep drains my laptop battery at only 2-3% an hour, so its not like its going to have a large impact on daily use.

 

Sleep,hibernate, and shutdown

Hi,

Usually, Sleep and Hibernate features are used to save power when using a computer. However, hibernate may not be available for all PCs as it was designed for laptops. Regarding your concern, since you’re trying to turn
off or disable these features, you may follow the step below:

• To turn off Sleep:
  
  Go to Settings > System > Power & sleep. Then, select
  Never from the drop-down list under the Sleep section.
  
  
  
  
  
• To disable Hibernate:
  

• Type Command Prompt in the Search box from
  Start.
• Right-click on it, then select Run as administrator.
• In the Command Prompt window, type powercfg.exe /hibernate off and press
  Enter. Close the window.

We’re just here if you need further help.

 

sleep or hibernate

I think you have sleep and hibernate confused... sleep just puts the computer in a low power state, making resuming the session faster... hibernate shuts down the whole computer and basically just saves whats in RAM to the hdd and loads it on next startup. IIRC...
