Your computer has power or energy settings designed to prevent all programs, including Off Fast, from continuously running in the background after a designated period of inactivity. With default settings, your computer likely will enter so-called sleep mode (or a similar mode) after only 15 to 30 minutes of inactivity. Once sleep mode, or a similar mode, is in effect, Off Fast cannot continue to protect your computer as designed. The Sleep Mode tab, like these instructions, is designed to alert you to this issue and show you how to resolve it.
What Are the Differences Between Windows 10’s Sleep Mode, Hibernate and Hybrid Sleep?
is a power-saving state that allows a computer to quickly resume full-power operation (typically within several seconds) when you want to start working again. Putting your computer into the sleep state is like pausing a DVD player—the computer immediately stops what it’s doing and is ready to start again when you want to resume working.
is a power-saving state designed primarily for laptops. While sleep puts your work and settings in memory and draws a small amount of power, hibernation puts your open documents and programs on your hard disk, and then turns off your computer. Of all the power-saving states in Windows 10, hibernation uses the least amount of power. On a laptop, use hibernation when you know that you won't use your laptop for an extended period and won't have an opportunity to charge the battery during that time.
is designed primarily for desktop computers. Hybrid Sleep, a combination of sleep and hibernate, puts any open documents and programs in memory and on your hard disk, and then puts your computer into a low-power state so that you can quickly resume your work. That way, if a power failure occurs, Windows 10 can restore your work from your hard disk. When hybrid Sleep is turned on, putting your computer into sleep automatically puts your computer into hybrid sleep. Hybrid sleep is typically turned on by default on desktop computers.
Since the settings for Sleep Mode, Hibernation, and Hybrid Sleep are in the same place in your Windows 10 control panel settings, disabling them takes only a couple of minutes.
Disabling All Energy-Saving Modes – Action Required!
Depending on your operating system, you may have to disable up to three energy-saving modes on your computer.
Disabling Sleep Mode on Windows 10 Machines:
- Open Settings app. To do so, click on the Settings app icon on the Start menu or simultaneously press Windows and I keys.
- Click the first option titled System.
- On the resulting page, click Power & Sleep.
- Now, under Sleep section, you will see two options:
For both options, expand the drop-down menu and select Never. That’s it! Your PC will never go to sleep mode again (unless you change these settings).
- On battery power, PC goes to sleep after
- When plugged in, PC goes to sleep after
Note that changes made to sleep mode will apply to the current power plan only. To make changes to any other power plans, switch to the other power plan by clicking the battery icon in the system tray and then click on the current power plan tile (as shown in the following image) to switch between all available power plans.
Once a different power plan is selected, rinse and repeat the steps above to configure or disable sleep mode for that plan.
While you must disable sleep mode (and similar modes) so Off Fast can function properly, you may turn off your display (monitor) after a desired period without affecting Off Fast operations.
Be careful when adjusting how long your Windows 10 computer waits before sleeping or hibernating, however. On a battery-powered laptop, inhibiting sleep or hibernation can result in data loss if the battery dies.
Now, on your Windows 10 machine, you must disable two similar modes before you can start using Off Fast…

Don't Sleep is a small, portable program to prevent system shutdown, Hibernate, Turn Off and Restart.
Do not block your computer from shutting down, however, as doing so prevents Off Fast from functioning as it should.
Don’t Sleep is freeware that allows you to automate disablement of Sleep, Hibernation and Hybrid Sleep.
Don't Sleep does not have to be installed and can be executed easily from the desktop, or it can be carried on a small flash drive or other memory device.
