![]() ![]() ![]() In case of a power outage, any unsaved data is lost and cannot be recovered. In sleep mode, the data is still in the RAM, which is volatile. During hibernation, data is automatically stored in a non-volatile memory before the hardware shuts down. ![]() Risk of data loss: Higher in sleep mode.Most laptops enter this mode when the machine is running on batteries and is closed. Only the CPU and the display need to be powered up. As a result the resumption on waking up is instantaneous. Hibernation provides the advantage of eliminating the need to save data before shutting down and restore the applications on power up.ĭuring sleep mode the computer cut power to subsystems that are not needed and places RAM into minimum power state. On start-up, data is read back to the RAM which takes about 10 seconds or more. Similar to shut down, a hibernating system needs more time to start up. The state of the computer upon resumption is the same before it enters hibernate or sleep mode.ĭuring hibernation, the hardware is completely powered down while the computer retains its state. The new kernel did not fix the sleep issue but brought the problems I had on Archlinux, such as constant stutters.Power button and standby light indicator State of the computer I would be very grateful for any help, and I would also be happy to submit any logs or any other type of information that might help identify the issue.Įdit: Corrected the Arch kernel version to 5.10.14-arch1-1, my bad!Įdit2: I tried the latest kernel on the Ubuntu mainline PPA (v5.11-rc7). This issue has been giving me headaches for a while now, because I really want to fully get rid of windows, which does not make a lot of sense while my system can't properly sleep on linux. Switching to Archlinux is not really an option, because while Archlinux fixed the sleep issue it also introduced a whole new set of issues like constant stutters, that I have no idea how to troubleshoot. Linux Kernel version of Archlinux was I believe 5.10.14-arch1-1.īTW I am using Ubuntu 20.10 with the kernel version 5.8.0-43-generic. However on Archlinux, if the system has been asleep and physically not moved for a while and I physically move the system, this again causes the system to wake up, however the system does not go into an endless cycle of sleep and wake. Indeed this problem does not occur on Archlinux. I have also tried Archlinux to see if the newer kernel and newer drivers would fix the issue. Interestingly, the system does not seem to wake up from sleep if I constantly move the laptop physically, which led me to believe that the issue is somehow related to an accelerometer or maybe to its driver. A while after that the system goes to sleep again, which causes the system to constantly sleep and wake up, causing a lot of battery drain. So the issue is, when i close the lid the system will briefly go to sleep ( I can tell that by the fans turning off ), however after a while the system wakes up again (and the screen turns on too) while the lid is still closed. I have been trying to get my system to properly sleep, however I can't figure out what the problem is and I also couldn't find any resources addressing my issue. ![]()
