In this file, at the end of the GRUB_CMDLINE_LINUX_DEFAULT line, before the ending ", add the following: resume=UUID=THE_UUID_FROM_ABOVE resume_offset=THE_SWAP_OFFSET_FROM_ABOVE Make sure your edits of this file are correct, or else your computer may fail to boot! kate /etc/default/grub Configure the session resume in the boot manager (GRUB)Įdit /etc/default/grub in order to boot with the resume and resume offset kernel parameters. The difference between sleep and hibernate is their power consumption. It is vital to give some break to your system to make it have better battery life and performance. The power supply to the components, except the RAM, gets. Get the offset (ie the file position as maintained by the Linux kernel) of the swap file sudo filefrag -v /fedora.swap | head -n 4 | tail -n 1 | awk '' Sleep, hibernate, and hybrid sleep are the options gives by Microsoft. 2 Sleep: Once the Sleep mode (Standby in earlier Windows) is called for action, the machine enters a low power mode. If you doubt about the name of the swap file, get it with cat /proc/swapsįind out the UUID (identifier) of the partition on which the swap file is located findmnt -no UUID -T /swapfile Image 770×639 60.1 KB Find the UUID and offset of your swap fileīy default, the installer creates a swap partition as /swapfile. Insert this line at the bottom (keep the blanks around resume) add_dracutmodules+=" resume " My SP8 does eventually hibernate after sleep, but I dont know how long it has to sleep before it hibernates. I cant find this setting on my SP8 (Win 11). A third approach is to suspend to copy the contents to RAM, and then hibernate which would also copy the contents of the RAM to the disk, so the power on is faster than powering on a computer and restoring the state manually. If the output includes disk it should be good. 1 I have my SP4 (Win 10) set up to hibernate after 5 minutes of sleep. hybrid-sleep Hibernate and suspend the system. Verify that hibernates works on your computer cat /sys/power/state Note: this document focus on swap file because the installer already have an option for having a swap partition with hibernation. Choose Change plan settings under your selected plan and. You need to unactivate it with sudo swapoff -a and create a new swap file by following this how-to. To activate Hybrid Sleep, go to Control Panel >Hardware and Sounds>Power Options. But since you got an ssd, boot time must be fast anyway, if you worry, just shutdown. ![]() So to answer: Meh, dont think youll ever notice it. When you put it to sleep, if 8gb were in use, the PC writes 8gb to the ssd. In case you have chosen to create a swap file or partition during the installation, without hibernation option, then your swap size is too small. ago Well, hibernation basically write the content of your ram to the ssd. Hybrid sleep is a combination of sleep and hibernation, current state is save in RAM and swap, so resuming session is quick, but in case of power outage or battery low, you can resume your session from swap file.įor being able to use hibernation of hybrid sleep, you need at least as much swap as you have RAM. It doesn’t drain battery but is slower to resume session. Hibernation is a power-saving state where current state is saved in hard drive (in swap). It still drain a little battery, but resuming the session is quick. So maybe i was misled by the internet or maybe that was all relevant in the past SSD and not the ones we we have now.Sleep is a power-saving state where current state (opened programs and documents) is in RAM. I know all that, the thing is i got scared by the internet saying that Hybrid and Hibernate kills your SSD much faster and Sleep can crash you SSD all of a sudden This way it allows you to "wake up" the system much faster but still provides you safety against power outages. It basically puts the system on low-power Stnd-by mode like Sleep mode but it also puts the data from your memory on the storage drive AND it leaves it on the memory. Hybrid is a combination between the two designed for desktop computers as redundancy against power outages. Hibernate is the same with the only difference that the data from the RAM is dumped on the storage drive and the system uses 0 power while in hibernation but it takes more time to "wake up" and does writing to the SSD. Sleep basically puts your computer in a Stand-By mode, putting all applications on hold but your system still uses some power to keep everything going as all the data is still in the RAM. ![]()
