Disable Hibernate and Erasing hiberfil.sys file corrects slow Windows 7

Windows 7 computers will no longer remain slow if memory is expanded via the disabling of hibernate and the deletion of ‘hiberfil.sys’.

One of the reasons attributed to a slow Windows 7 PC is less amount of memory. And when chain hibernation that’s enabled is followed, with heavy ‘hiberfil.sys’ existing, the computer suffers from less memory.

Incidentally, the term ‘hibernation’ means the state of power conservation basically on laptops. Actually when a system is in sleep mode, user-activity together with settings is placed in memory, so extraction of power is low. But, when hibernation is enabled, applications and open documents are placed on the system’s hard disk followed with disabling of Windows 7. Interestingly, amongst many situations of power saving within Windows 7, hibernation utilizes power in the amount that’s the lowest; however, it uses up over 50% of RAM (Random Access Memory).

Meanwhile, when the Windows 7 is in a hibernation state, the system establishes the “hiberfil.sys” file that’s used when Windows 7 is restarted.

In case user does not close Windows 7 rather puts it in hibernation state, he’ll find that it’s nearly immediately possible to access Windows 7. That’s a very big benefit of hibernation i.e. user needn’t wait to have the PC start up first. However, hibernation has many drawbacks too. It saves the whole lot of running software’s information prior to taking up the hibernation state and that leads to an excessively large hiberfil.sys file, which eventually consumes so much of RAM that the Windows 7 computer becomes slow.

The following are the ways in which hibernation along with hiberfil.sys leads to a slow Windows 7:

  1. It eats up energy along with system resources.
  2. It occupies the major part of RAM or disk space that lowers memory and with a large hiberfil.sys file.
  3. It increases the number of disk fragmentations and also very slowly because of the hiberfil.sys stored on the computer’s hard drive

Hence, one of the methods by which Windows 7 performance can be avoided is to first disable “hibernation” feature followed with erasing hiberfil.sys file.

So for turning off hibernation, the steps involved are:

  1. Viewing Power Options where advanced power configurations are to be changed then extending Sleep followed with enabling Hibernate after.
  2. Configuring the Setting (Minutes) for the Never option.
  3. While enabling Allow Hybrid Sleep, configuring ‘Setting’ to ‘Off.’
  4. And finally, pressing ‘ENTER.

Now following deactivation of hibernation mode, the large hiberfil.sys file must be deleted. The steps involved are:

  1. Clicking Start, going to Start Search box and typing in ‘cmd.’
  2. Right-clicking on ‘Command Prompt’ that’s obtained from the search outcomes, and subsequently hitting on ‘Run as Administrator.’
  3. Whilst User Account Control prompts, clicking on Continue.
  4. In Command Prompt field, typing in hibernate off/powercfg.exe followed with clicking OK alternatively, typing in powercfg.exe –h off followed with clicking OK.
  5. Thereafter, typing in ‘exit’ and clicking OK for removing the Command Prompt box.
  6. Finally reboot your Computer.
