Windows 8.1 - High CPU Uptime (Is it really 'shutting down'?)

Evening all!

Quick question here - when I shut down my laptop (Lenovo ThinkPad L540) and then start it up from cold again, I notice my CPU uptime doesn't go back to 0 - it carries on from where it was when I was last using the laptop.

I am shutting Windows down from the Start Screen and selecting Shut Down - NOT by pressing the power button on the laptop or closing the lid (both of which are set to sleep).

I just shut the machine down and started it up again and I notice that my CPU uptime is still 2 days: http://i1160.photobucket.com/albums/q487/vistakid10/TaskManager_zps16b8aa20.png

I think the last time I did a restart from Windows was 2 days ago, so when I do a restart it goes back to 0, but when I shut down and boot up from cold it doesn't.

I've had a look in the Power Options but there is nothing that suggests that the Shut Down button is actually hibernating the laptop or similar, but I may be missing something. Would disabling hibernation be a good place to start?

Any ideas?
Thanks!

 

That's because by default Windows 8 does hybrid shutdown. it's not really a full shutdown, it shuts down your system and apps but keeps stuff like drivers and stuff in a hibernation file. so lets say you turn off your computer. install a new HDD, then turn it back on, the sytem won't even see the new HDD until you restart because your shutdown wasn't actually a shutdown

that's why I created a shortcut with this command shutdown.exe /s /t 0

then I gave it the Shut down icon

so when I want to do a full shutdown and clear my RAM and stuff, I double click on the shortcut

with that said, I installed Windows 7 and i'm done with 8

 

Try this "Full Shutdown" method. :thumbsup:

How to Do a Full Shutdown in Windows 8 Without Disabling Hybrid Boot

 

Turned off hibernation. Seems to have done the trick. Boot times are a little bit longer though. I'm on an SSHD so I'm going to try doing a bunch of restarts and see if it improves again. This is the annoying things about SSHDs (and Windows 8) I guess.

 

Fast boot is the first thing I used to disable when I installed Windows 8. When I shut down, I want a full shut down not some freakin' hybrid hibernation/shutdown

 

I have an SSD in my desktop and I disable hibernation because it uses up a few gigs of space (and my SSD is only 128GB) but I forgot to disable it on my ThinkPad since having 1TB I wasn't concerned about space.

I see that having it enabled makes Windows a little faster to boot and shut down but after having done restarts on my SSHD it seems to booting up reasonably quickly. I too want to have a proper shut down and not a hibernate, so disabling hibernation seems to have done it.

I used to have some shut down buttons on my Start Screen before the Windows 8.1 Update came out and added them to the Start Screen, haha.

 

other than consuming a signigicant amount of space, it also does a lot of writes to your SSD since it needs to save some of the current Windows environment to the hiberfil.sys

My Samsung Magician automatically disables hibernation and sets the page file to a minimum of 200 MB / Max of 1024 MB and disables Superfetch when I hit it's magical reliability OS optimization button so you might wanna do those settings manually as well

also right click on each SSD partition, and remove the checkmark that says allow context to be indexed

SSDs are superfast they do not need indexing to find stuff fast

 

Thanks for the tips will have to do this when I am back on my desktop. I don't have a Samsung SSD in my desktop (it's an OCZ Vertex 4) but I'll do it.

Done some reboots on the laptop with the Seagate SSHD. Seems to be booting/shutting down/rebooting quickly enough for my liking I think. Not got a stopwatch on me but I think it's booting in less than 20 seconds so that isn't bad. It was about 10 before but it will probably get a little bit quicker the more reboots I do.

 

bro, you cannot even compare a hibernation to a full shut down, they r different. but think of it

when you go to bed and want to shut down, wouldn't you want your RAM to be cleared and start fresh again when you startup? IMO, that hybrid shutdown is a bit of a lie, its like sleep but + a full system power shutdown

in both cases, 20 seconds is super fast man, it's not like the world is gonna fly if you don't get a 15 second start



you have 8 GB RAM, I would recommend setting your page file to a custom size of 1024 min / 2048 Max

 

Little extra tip if you use Magician software; I have a Samsung Evo and the software that goes with it called Magician has a feature under OS Optimization that allows an advanced tab to deactivate hibernation mode. No shortcut needed if you use this software.

 

I'm not really a fan of hibernation anyway to be honest. Over time you tend to get problems with Windows acting weird and crashing and then you reboot and 'magically' the problem is solved!

Prefer proper shut downs.

But yeah I guess my speeds are pretty quick,

Shut down in about 15 seconds.

Boot up in about 17 seconds.

Not bad going.


...and a few more reboots later I've cut about 2 more seconds off each: Boot up: 14-15 seconds, shut down: 13 seconds. Pretty nice.

At least it is doing proper shut downs now. I guess if I need it to shut down any quicker I could always re-enable hibernation but I'm happy with the speeds I think.

 

want a speed boost for shutdown?

1) click CTRL + R

2) Type Regedit

3) Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL

Look for WaitToKillServiceTimeout

Change the value from 5000 to 1000

enjoy

 

I use an app called: PC Monitor that has two separate commands: Shut Down and Power Off. That will do a full shutdown in Windows 8.1.1. The regular shutdown command doesn't really do Shutdown.

 

That sounds good, but I don't have a Samsung SSD. I've got an OCZ Vertex 4 in my desktop and a Seagate SSHD in my laptop, but I think if I replace the SSHD in my laptop I will probably get a Samsung SSD (unless anybody comes out with anything faster by the time I buy).

Thanks for this. I remember doing this on Windows XP years ago.

It saved a couple of seconds off my shut down time (12 seconds).

That's good enough. :thumbsup:
