Laptop Hibernating on its own on Windows 7- How to fix it?

Does your Computer or laptop Hibernates on its own? Here are some methods to fix the problem. Hibernate mode is a power management mode that conserves power by powering down the system. In hibernate mode the current state of the system is saved to the hard drive and the system will power down. When a user turns the system power back on, the saved information is read from the hard disk, restoring the last used settings. Hibernate mode is similar to sleep mode. However, in sleep mode the power cannot be shut off. You can enable or disable hibernate mode to overcome the problem of system hibernating automatically. Fix the problem by following the tutorial.
