The shutdown of the screen image after some time of computer idle time is programmed in almost all operating systems used today in home and office conditions. This is done to reduce power consumption and extend the life of the displays. This setting can be canceled or tweaked.
Instructions
Step 1
If you need to disable the screen lock in Windows 7, then press the Win button or click on the "Start" button and in the field labeled "Find programs and files" of the pop-up menu, enter the text "power". This is enough for the operating system to find and display a list of its components related to energy saving settings. This list will also contain the component you need with the name "Screen Off Settings" - launch it by clicking the mouse pointer.
Step 2
Expand the drop-down list located on the page of this component opposite the "Turn off display" caption. In the list, you can select one of the options for the duration of the delay before disconnecting or deactivate this function altogether by selecting the bottom line - "Never". Adjust the value in the "Put the computer to sleep" field in the same way, and then fix the new settings by clicking the "Save changes" button.
Step 3
If you want to undo display off in Windows XP, start by right-clicking on the background image on your desktop. This action brings up a context menu in which you need to select the bottom line - "Properties". After launching the component responsible for display settings, go to its "Screensaver" tab and click on the "Power" button to open the settings window for the properties of the power supply.
Step 4
Select the value "never" in the drop-down lists "Turn off the display", "Sleep mode after" and "Sleep mode after" if you want to disable the screen lock in the most radical way. You can set a softer option by selecting one of the time intervals in these lists. Then click the OK button and your changes will be saved.
