[Q] does Windows 8 really shut down?

Hello all,

I'm using Windows 8 Professional (got it from MSDNAA as soon as it appeared there :p) and it seems to me that Windows 8 doesn't really shut down properly. I attached an image taken with Snipping Tool and it showed that the CPU up-time is 4 days etc etc..

The inconsistency here is, I just booted up my laptop few minutes ago. I did shut down my laptop properly every time. The only explanation here is that this 4 days ago was the day when I placed my battery back into the laptop.

but the laptop supposed to shut down PROPERLY right? can someone explain this to me?

thank you :)

How are you shutting it down? Pressing the power button? Or going to Settings->Power->Shut Down?

The reason is that the behavior of closing the lid, or pressing the power button can be configured, and I think laptops are configured for hybrid sleep mode (where it sleeps but also writes to a hibernate file so it can recover if it loses power). Check the advanced power options for your current settings.

No it does so even if you power off by going to Settings->Power->Shut Down....
But if you restart your system, then CPU uptime restarts from zero. And also if you disable your "Fast Startup" option and then shutdown and power on , CPU time restarts from zero.
It's all because of "Fast Startup" option. Now i know that this option is made to boot faster but what effect does it have on shutdown??? I guess it doesn't shut down system properly, instead force it into some hypernation mode or so.

Removing the power cable doesn't affect anything. The hybrid boot is a good thing.

If you still want a fresh start once in a while do a restart (just did the test) and the uptime counter resets itself.

ok thanks. So does it really like consume my battery? just want to make sure so that I won't have a day when i turn on my laptop and see that I have no battery left.

It does not use any battery. Basically, instead of writing the contents of RAM to hiberfile.sys, the kernel gets written to hiberfile.sys. When the PC is powered on, the system reads the kernel contents directly from the file instead of loading them all from scratch. On an SSD, combined with UEFI, it does make for a speedy boot.

No, hibernation does not consume power. It writes your memory to the hard disk where it is available the next time you boot. Now the sleep mode keeps the memory alive and consumes a small amount of power.

Wow thank you all, so many experts and knowledgeable people here. So I'll just leave the laptop as it is? But the weird question is: Does the contents of the RAM not written to the harddisk when shut down if battery is not inserted? It seems to me that the up-time of the CPU only continue to count ONLY IF the battery is inserted.


Btw, a little OT: what's UEFI?

UEFI: Unified Extensible Firmware Interface - Wikipedia, the free encyclopedia

In short it should replace the BIOS on newer systems allowing faster transfer modes on boot.
It was about time to improve/replace the BIOS which principles are mainly the same since the 70s when it was first introduced.
