tl;dr: power states in your computer are controlled by an implementation of ACPI (advanced configuration and power interface). At the end of a shutdown process, your operating system sets an ACPI command indicating that the computer should reboot. In response, the motherboard resets all components using their respective reset commands or lines, and then ...

I don't have time right now to do thorough research, but here's a starting point: Chips usually don't turn off and then turn on. Instead, there's a reset line which will bring processor in so-called reset state when usually all memory is cleared and processor looks like it's just been powered on. While that pin is held high (or low, depending on the ...

You will get an error message from the Windows Resume Loader on restart. You will get this nasty warning: Your system's memory configuration has changed since it entered hibernation.

To help diagnose the restart, what you should first check is Event Viewer. Just enter eventvwr in the run dialog (which can be called by pressing Win + R).

This blog post describes how Linux triggers a reboot. Excerpt: Linux has a bunch of different ways to reset an x86. Some of them are 32-bit only and so I'm just going to ignore them because honestly just what are you doing with your life. Also, they're horrible.

Straight from Microsoft Blog: Here’s the key difference for Windows 8: as in Windows 7, we close the user sessions, but instead of closing the kernel session, we hibernate it. Compared to a full hibernate, which includes a lot of memory pages in use by apps, session 0 hibernation data is much smaller, which takes substantially less time to write ...

There's a lot of folk wisdom that Adobe Acrobat Reader requires a reboot because of its Speed Launcher. This is not, in fact, true. Speed Launcher installs itself in the Windows Explorer "All Users" Startup folder. Thus invoking it after installing it only requires that one log off and then log back on again. Indeed, one could just run the Speed ...

On Windows, you need to reboot because a DLL (or EXE) file cannot be replaced while it is in use. Some drivers and services do not support "unloading" and so you must reboot if you want to replace DLL or EXE files that are used by those. However, the majority of drivers and services can be restarted independent of the rest of the computer, so you can ...

No reboot should be necessary. You can apply it manually ...

This seems to be connected to what @LightBulb said. In this thread the second post mentions: this happens becasue of the new Shutdown/Boot mechanism from Windows 8 which is basically a logoff + Hibernation.

Sometimes a piece of software will make a change that cannot come into effect while the computer is use. Some reasons might be - a file is in use, the change can only occur during boot up of the computer, there might be a security issue which can only be done before the computer has its networking active, maybe the virus scanner would interfere with the ...

You can launch task manager by pressing control-shift-escape, handy to know if control-alt-delete isn't playing nicely. Kill the explorer.exe process, then file, new task, explorer.exe.

The answer Marcus Adams gave also has a keyboard shortcut: Ctrl+Alt+End. You do have to be in full screen and/or have the RDP session set to Apply Windows key combinations on the remote computer. This effectively sends a Ctrl+Alt+Del to the remote computer (so it's handy to know for other occasions/uses too). From there, as Marcus said, you can get to ...

If Ubuntu is still using Alsa for its sound engine (I'm not sure as its been awhile since I've used it), you can restart by typing sudo /etc/init.d/alsa-utils restart into the terminal. Since it doesn't seem to be working, you might need to make sure that nothing is trying to use it. (example shamelessly stolen from the Ubuntu forums) name@comp:~$ lsof | ...

"Cloggy" is a subjective word. At work, we baseline the computers using Performance monitor. Then we compare current performance against what we know for sure is a clean computer. The human senses are easily tricked. Just ask a magician. To get a easy quantitative measure of your computer, I suggest you start up Performance Monitor. Click the Data ...

When you execute a shutdown, Windows initiates a shutdown sequence. It sends an END message to all running processes. Each process then starts it's own END sequence. Windows waits for a response from each process that says that the process has successfully ENDED or if it requires more time. IF the process requires more time, it sends a DELAY message to ...
