When a computer is stuck in power save mode you will usually have to open the computer and remove and replace the battery from the mother board. Once the battery is removed you should be able to re-start the computer normally.
Type sudo nvram boot-args="" (including the quotation marks) into the command or "terminal" line.
Press "enter" and follow any onscreen prompts to restart your computer.

Hibernate is a power mode that allows the computer to save an image of the desktop to the hard drive and enter a state of reduced power consumption to save energy.
That means your computer has entered a state of Hibernation to conserve battery life. Very useful if you're working on something at work or school, and you want to resume the progress at home.
Hibernate.
To save power
turn off power save mode
Control Panel --> Power Options
You can do it from Power Option in Control Panel.
run, the computer is doing calculations normally (maximum power consumption)sleep, the computer is not doing calculations but maintains DRAM refresh to retain data internally (low power consumption)hibernate, the computer is not doing calculation but saved DRAM to a disk file so that DRAM refresh can also be stopped (minimal power consumption, often the computer actually turns off in this mode)
It shouldn't. I have Charter cable and do this all the time. Sometimes to save power your computer may shut off the adapter. Check your settings to make sure this is not a power save feature that needs to be turn off.
When you put your computer in stand-by mode below are the things that happen in general- 1)Your processor goes into sleep mode(In this mode it stops processing but saves its state) 2)RAM goes into sleep mode(It saves state,and read write are not allowed to save power-Depends on your mother board) 3)Devices like mother board and keyboard or speakers are cut off power. All this saves power and also saves overworking of your devices. And so it is a good practice to out your computer into Standby mode when leaving it for short period of time.
Standby, power mode
