While you can modify power settings via the Control Panel, the most effective way to disable hibernation—and delete the hiberfil.sys file automatically—is via the Command Prompt.
When a computer enters hibernation, it takes a snapshot of your system’s memory (RAM) and saves it to the hard drive before powering down completely. This allows the computer to resume exactly where you left off without drawing battery power, unlike Sleep mode, which requires a small amount of power to maintain data in RAM.
: Since hibernation writes the entire contents of your RAM to the disk, disabling it reduces unnecessary write cycles on your SSD. hibernation disable
If you change your mind, the process is easily reversible. Open Command Prompt as Administrator and run:
Hibernation is a power-saving feature in Windows operating systems that allows a computer to save its current state to the hard drive and shut down, while still allowing it to resume where it left off when powered back on. While hibernation can be a useful feature, there are times when you might want to disable it. In this write-up, we'll cover what hibernation disable means, its benefits, and a step-by-step guide on how to disable hibernation on your Windows computer. While you can modify power settings via the
: Windows "Fast Startup" often relies on a partial hibernation file. If you disable hibernation, Fast Startup will also be disabled.

For optimal balance, administrators should consider (e.g., powercfg /h /type reduced in Windows, which limits file size to 20% of RAM) rather than a complete disable. This maintains crash dump functionality and fast boot capabilities while freeing significant storage. : Since hibernation writes the entire contents of
: Professional and Enterprise users can check the Group Policy Editor under Computer Configuration > Administrative Templates > System > Power Management .
: The hiberfil.sys file can take up a significant amount of space, often roughly 75% to 100% of your installed RAM. On a 16GB system, that is a massive chunk of your SSD.
