Disable Power Management In Windows 7 And Vista.

IT Problem

In windows 7 you may have issues with machine hangs, crashes when the system is under extreme load. If you go to control panel > Admin Tools > Event Viewer, under the system log you may see the error below.

Event ID-41
Source-Kernel Power
Log-System

This is a well known issue in Windows 7 sometimes it may be resolved with the latest service pack but it can also be resolved by disabling the power management sub system.

IT Solution

So we will disable the windows 7 power management.

First right click on the battery or plugged in battery icon in the far right hand corner of the task tray.

windows 7 power

We are then going to select power options so we can modify the power profile. You will see you system has either pwer saver , balanced or performance as default. Mine is performance. ( by the way there is no reason why you would not always run it on performance, balanced is a pain in the backside when on battery as it runs cpu stepping meaning the cpu runs slower when on battery to save power ).

You will then need to click Change Power Plan settings on your chosen power profile.

Now that we are are in your chosen profile its just a case of settign everything to never.

This now means that none of the default power management settgins are enabled. You could also change the default windows 7 shutdown options if required. If this does not resolve your issue consider running a windows 7 file repair.
