Get Fast Startup Time in Ubuntu by Enabling Hibernate (Tutorial)
<p><strong>Hibernation</strong> involves transferring all the contents of a device’s <strong>RAM (Random Access Memory)</strong> to the disk before shutting down the device. Upon device restart, it seamlessly resumes from the exact point where it left off. This means all your files and applications are instantly accessible in the same state as before hibernation, even any unsaved work remains intact.</p>
<p>This is useful for laptops with limited battery power. It can also be set to happen when the battery is low. Laptop computers use hibernation to save energy, and it’s handy if you need to change the battery quickly. A sudden power cut or failure won’t lead to data loss because your information is preserved in non-volatile memory, like SSDs, Flash Drives, or Hard Disks.</p>
<p>Hibernation is similar to sleep mode, known as <strong>suspend</strong> in <strong>Unix</strong> systems. In sleep mode, the device keeps the RAM active, saving its contents, while turning off other components to save power. This allows for a nearly instant resume when you wake the device. In sleep mode, any sudden power failure will result in data loss as the RAM does not save data when it’s powered off.</p>
