Does Laptop Still Download In Sleep Mode
Melva Badertscher
I've come over from a Thinkpad which did not have bluetooth running in sleep mode and I'm finding this really annoying as I keep forgetting to turn bluetooth off on the laptop and my headphones keep trying to connect from the other side of the house when I'm not working.
I was always using Sleep mode and I thought that if I turn off electricity while PC is sleeping, it will just hard shutdown without saving any data / open apps, etc.
Today I accidentally turned off electricity for my PC (when it was sleeping), I was quite surprised when I turned it on and after boot I saw all these open apps, just like it was sleeping all the time without power interruption.
I'm pretty sure that in previous versions of Windows hibernation and sleep were two different things, now it seems that Windows saves state on disk everytime in case of losing power source and just still keeps it in RAM to instantly turn on.
Yes, that is exactly what Windows is using in your case. It is a mode called Hybrid Sleep. While it is still possible to setup Windows to go into a strictly sleep or a strictly hibernation mode, by default Windows 10 sleep mode is set as Hybrid Sleep on desktop computers if supported by the system. (The command powercfg /a gives you a list of actually supported power states regarding your system.)
I noticed the same thing. I opened my Laptop after the weekend when I am sure I had put it to sleep - essentially I wanted to test how much battery Sleep used, it had seemed quite modest. I was prepared for the worst.
Hybrid sleep is OFF. On a laptop this is really just a potential battery flattener. It is really Sleep with Backup. It Sleeps AND saves the state to a hibernate file so that if power is lost it will seamlessly recover. It still uses some power to maintain the RAM for sleep mode.
I'm thinking more in terms of energy costs. How much energy does it cost to keep your PC in sleep mode? Is it negligible or substantial enough that during long periods of non-use, I should be shutting down the PC?
Sleep mode will keep the RAM and usually all of your USB devices powered. The USB devices will either go into a sleep mode as well, or continue operating. For example, my USB mouse will turn its lights off when my computer sleeps, but I can still press a mouse button to wake the PC.
Sleep mode is a power saving state that stops all actions on the computer. Any open documents and applications are moved to the system memory (RAM) and the computer goes to a low-power state. This is similar to pausing a movie DVD. The computer is still powered on, but uses less power. Devices such as monitors also use sleep or standby mode to reduce power consumption.
Instead of shutting down the machine every night, I am planning on leaving the computer in sleep mode. I am wanting to make sure that my computer won't pick up any sounds from my bedroom when I put it on sleep mode at the end of the workday. I would be mortified if Teams glitched and a co-worker was able to hear private conversation or worse!
I was running a batch of 116 (150MB+) las files through lasheight (from LAStools) in a ModelBuilder iterator without realizing the laptop battery had been unplugged... I understand when the computer goes to sleep and is turned on again ArcMap treats the map as if in a new session- does it also affect model outputs (being saved to the computer)?
Yes it messes everything up. I would suggest doing it again and making sure your laptop is plugged in. If it is going to take a long I would I would also suggest disabling your computer going to sleep and or hibernating
I have 64 GB of the Vengeance RGB mode but when PC is in sleep mode the lights stay on, which with 8 sticks can stay very bright. I resort to having to cover my PC with at night with a sheet to block out the light. I would like to be able to set the lighting to turn off when PC is in sleep mode but can't seem to do this. I have read that you can turn off the "Enable full software control" setting in iCue but my version of iCue 3 (latest version) doesn't show this option anywhere. I downloaded iCue 4 instead but same deal, so reverted back to iCue 3 so at least my cooler is available.
For CUE 3, you need to turn off "enable full software control" in the RAM settings. This drops you into hardware mode. Now set a static black effect for the RAM. Go back to settings and re-enable full software control and you are now back in software mode. The new static black disappears (hidden setting) and you can set up whatever lighting effect you want. This will be active anytime the software is running. The black/off will return when CUE Is not running or those soft off power states like sleep mode.
So you have to install software in order to turn off the lighting on the ram? If my PC was in sleep mode, it would make sense but when it is powered off, these should not be lit up. I just installed them this morning, I walk by the room and it is lit up and discover the PC is off and the RAM lighting is on.
Guess I have to turn off the power strip as well.
Disabling the hardware lighting also turns of the RGB when you close the iCue software. Shouldn't it work the same as the H150i Elite LCD. It turns off when asleep but the hardware lighting settings is what stays on when the app is closed. It says it in the description. So if I close the software the RGB will be off and the H150i Elite LCD still on, doesn't seem to make sense. I guess I will have to keep iCue running which isn't really a problem but I shouldn't be forced to just to get the RGB to work as intended.
I wonder if there is a difference between using sleep and shutting down in terms of pump longevity. I just had to replace my EK 360 AIO as the pump failed 2 months short of 2 years so it was still under warranty. I replaced it with the H150i Elite LCD. I used sleep a lot and used variable pump RPM which was set to the CPU temp and I see now was not a good idea as it was in constant change. There was no way to set it to the liquid temp as I have now with the fans. I do set the H150i pump on balanced as I haven't worked out if I can set it to variable based off the liquid temp.
No, not for the pump. That is definitely off when in sleep mode. The MB and RAM are on, and then there are specific additional settings for MB related stuff like USB ports. This why your KB or mouse sometimes lights up in sleep mode as well.
Well worked one time after restart... when the pc is put to sleep second time it won't turn off. The problem is that the icue software does not automatically put the hardware mode on when the pc goes to sleep and it keeps the lighting mode... so every time manually and when I forget I have to wake up and manually put it to hardware mode. So annoying...
After a certain amount of time, my windows computer goes into sleep mode. I am currently using PowerShell to run multiple programs in succession. I do not want to change the settings so the computer doesn't go to sleep. I want to find a way in which when the computer goes to sleep, PowerShell continues to run the python codes in the background. This way, I can also keep my computer locked if I am not at home. The reason I want to do this is that I need to produce a lot of data and plots in a short amount of time.
Check your computers "Power Options" in the Control panel. You don't need to worry about the screen locking because as long as the computer doesn't get put to sleep, your process should continue to run. However, if your system is set to sleep after a set amount of time you may need to change this to Never. Keep in mind there are separate settings depending on whether or not the system is plugged in.
Under Windows there are MANY programs that will prevent the computer from entering sleep or wake it from sleep (including Windows itself. It does house cleaning, indexing, and updates during this time). You can run powrconf.exe /lastwake (I think, might want to google/brave that) to see if something woke it from sleep. I would also go into the advance power settings, and under sleep disable ALL wake timers.
The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.
This standby state is disabled when S0 low power idle is supported.
Our Dell servers and, I expect, all others do have power saving modes that allow servers that are idling to slow down clock and fan speeds for example to reduce power consumption. That is not the same as a full sleep though.
Usually servers use the hours when there isn't much user-generated load (typically at night) to run background jobs, like system backups, batch jobs, etc. and aren't idle enough to be allowed to enter an actual sleep mode.
If you experience that the computer does not wake up from Sleep or Hibernate mode, please connect an AC adapter and make sure the battery charge indicator is ON (The below takes the laptop as illustrated.), then click the Power Button to wake up the computer. (If the computer goes into Sleep mode for a long time, it will transfer the power status from Sleep to Hibernate mode and you can only resume the system by clicking the Power button.)
