Win10: USB mouse/kb doesn't wake the computer.

It sounds like there could be a few different issues here. Disabling the hiberfil.sys file through the CMD can cause problems with the sleep function, as this file is used for hibernation. If you want to use sleep properly, it's best to leave this file enabled. The hiberfil.sys file is not necessary for the mechanical hard drive to spin down, as this can be controlled separately.

It's also possible that the minimum power state for the CPU cooling is not being controlled properly if the fans are not on the CPU fan motherboard plug. Maybe you can check the fan connections to make sure they are plugged in properly and being controlled by the motherboard.

As for the USB wake options, maybe your motherboard simply doesn't have this feature. Some older motherboards may not have this capability, and wake options for serial ports and PCI devices are more common. A USB device is technically considered a communication device, but it's not always listed as such in the BIOS.

Regarding the "F2 thing" you have to hit for the computer to start up, this is likely a setting in your BIOS called "Quick Boot" or "Fast Boot." Enabling this setting will bypass some of the initial startup checks and allow the computer to boot up more quickly, but it may also prevent you from seeing certain messages or options during startup.

Finally, regarding hibernation and sleep, these are two different power-saving modes in Windows. Sleep mode keeps the computer running in a reduced power state, while hibernation mode saves the contents of the computer's memory to the hard drive and then shuts down completely. When the computer is turned back on, it restores the contents of memory from the hard drive and resumes where it left off. Both modes can be useful for saving power, but hibernation mode uses more disk space and takes longer to start up and shut down.

This morning I noticed my computer was not waking up. It had gone to sleep last night. Some things I noticed that seemed odd:

The keyboard/mouse lights were off. I unplugged and plugged them in and they came on but still didn't wake up the computer.

I wonder if the problem with the sleep function was that I asked it to sleep but disabled the hiberfil.sys file through the CMD function so maybe it can't work properly. Does that have to be used if sleep works properly? If I want the SATA mechanical hard drive to spin down? Also I set the minimum power state for the CPU cooling to passive but I probably have those fans not on the CPU fan motherboard plug so its not controlling it. I'll check that later.

I went into the Bios and everything looked the same but I noticed I could see my mouse cursor. That was a first! I restarted and it was still visible in the Bios.

I noticed there was no USB wake options in my Bios. Its an old DDR3 motherboard. There are wake options for serial ports and PCI devices.

Under Automatic boot sequence its disabled for "when a communication device wakes the system". Could a USB device be a communication device?

My Bios has this odd F2 thing that I have to hit for it to startup. Can't seem to get around that. Makes restarting with updates a real headache because you have to be there for each restart. But that's a Bios thing not a Microsoft thing I guess.

Its strange how everyone talks about hibernation but that word isn't really used much in Win10. Just sleep. In Win7 they mentioned it in the settings. Is it one and the same?

Great to hear that disabling the USB selective suspend setting worked for you!

Regarding the "USB settings" option, it may not be visible for all users depending on their hardware configuration. It's not a problem if you can't see it.

As for hibernation, disabling it can definitely free up space on your C drive. Moving the hiberfil.sys file to another drive is possible, but it requires some technical know-how and is not recommended for novice users. It's better to just leave it disabled and get a bigger SSD when you can.

Moving browser caches off the C drive is possible and can save a lot of space. Most browsers have an option to change the default location of the cache folder. CCleaner and TreeSize are great tools for monitoring and cleaning up space on your drive.

Regarding the backups in the C:\Windows folder, it's best not to move them to another drive as they are an important part of your system. However, you can use Disk Cleanup to delete unnecessary files and free up space. Be careful not to delete important system files.

> Let's make sure that you have enabled the "Allow this device to wake the computer" option for your USB device in Device Manager. 

It is.

It was enabled but now its disabled.  I tested Sleep and it works great now.  Back to normal.  You nailed it.  

It would have been smarter for Microsoft to label it more logicly:  Like "USB wake from Sleep"  Who knows what "USB selective suspend setting" could mean?  

> and the "USB settings" are set to "Enabled." 

Not sure what this is.  Its not there.  

As for Hibernation I think I used Command to disable it because it seemed to be the only way of freeing up significant space on C drive.  I'll just leave it disabled until I get a bigger SSD for C drive.  No big deal.  Anyway because its not on C drive now (yes hidden files are displayed in folder options) I'm OK for a little while.  I should find a good deal on a SSD soon.  I'm squeezing by with a 30gb and its ridiculous as I have only 4gb free.  I've got every possible program on D drive.  I just wish I could move something like the Winsxs folder off C drive.  Now THAT would make a huge difference. 

I was able to delete DriverStore on a Win7 installation with no apparent problems but I've not been able to do that since or with  Win10.  It just says its inaccessible.  Not sure what magic I used before.  

Has anyone heard of moving the cache of browsers off C drive?  Those can take up a lot of space.  I run CCleaner daily to keep it trimmed down.  And TreeSize is great for monitoring what is hogging space.  Program Files is about 200mb.  Windows Explorer using Tiles is handy as it shows how much space each drive has. Very handy Microsoft.

There's a lot of backups in the C:\Windows folder.  Maybe some can be moved to another drive?  They waste so much space.

Hello! My name is Cristiano. I'm an Independent Advisor. I'm glad to help you.

Ok. Let's make sure that you have enabled the "Allow this device to wake the computer" option for your USB device in Device Manager. To do this, go to Device Manager, locate your USB device, right-click on it, and select "Properties." Then, go to the "Power Management" tab and check the "Allow this device to wake the computer" option.

If this option is already enabled, you may need to check your power settings to ensure that USB devices are allowed to wake the computer. To do this, go to Control Panel > Power Options > Change plan settings > Change advanced power settings. Then, expand the "USB settings" option and make sure that the "USB selective suspend setting" is disabled and the "USB settings" are set to "Enabled."

Regarding hibernation, by default, Windows 10 should have hibernation enabled. However, if you cannot find the option to enable hibernation, you can use the Command Prompt to enable it. Open Command Prompt as an administrator and type "powercfg /hibernate on" without the quotes, then press Enter. This should enable hibernation on your computer.

As for hiberfil.sys, this file is necessary for hibernation to work and cannot be moved from the system drive. However, you can reduce its size by running the following command in Command Prompt: "powercfg /hibernate /size %" without the quotes, where % is the percentage of your RAM size that you want to allocate for hibernation. For example, if you have 8GB of RAM, you can run "powercfg /hibernate /size 50" to allocate 4GB for hibernation. This will reduce the size of hiberfil.sys on your system drive.

I hope this helps!
