Inside a computer is a BIOS which is a small chip that holds essential information for the computer to start up, including the time. While the computer is plugged in, a small battery is being charged inside the computer, so if you unplug it, the battery takes over and the clock stays correct.
The battery lasts a very long time, but if you were to unplug the computer and leave it long enough, the time would be forgotten and you would need to set it again next time you turn the computer on.
Simply power it on. The new OS will automatically update each file as it boots.
What automatically restarts..? Your computer, your server, your printer, your router, your playstation...?
A UPS (Uninterruptible Power Supply) has a battery in it that will give you a short window of time to save your work and power down your computer. Some models have software that will tell the computer to save everything and power down your computer without you having to be there.
To power your computer without a battery
You put your memory card in your computer, download the songs on your computer and put it in the memory card. You can download .mp3's to your micro SD card. After you transfer the songs, turn off your Seek and power it back on and it will automatically update your playlist and your songs will be available!
No it will do it automatically to restart itself once you have updated it via iTunes, it's a restart rather than a power off.
Computers automatically default to the built-in display on power-up. It's part of the BIOS (binary in/out system) & POST (power-on self test) routines. That's simply because it's 'logical' for the computer to need to use the display it was provided with at manufacture. The only way to make it default to an external display - would be to have the computer automatically detect if an external monitor is plugged in. That would require extra software.
Because without power, the hard drive, the fan, they make noise when they have power. Without it, they all stop making the computer go "quiet."
Not sure what you are trying to update. Sometimes when you update something on your computer, you have to turn your computer off and then turn it back on for all the updates to install.
Take out the PSU (Power Supply Unit) It's the largest box inside your computer with a fan on it. Without power = no computer.
Your motherboard may not be configured for software power management.
Might be a virus or power problem. Also, check the cooling fan. If the cooling fan isn't working properly, your system can quickly overheat and will shut itself off.
