My Dell Notebook keep turning display off and going into sleep mode.

Hi Brink

I'm having a problem with my notebook. It keeps turning display off after idle for 2 or 3 minutes and going into sleep mode around five minutes after that. I did change and set power system in control panel many times but it did not work. I'm runing on Window 7 home basic 64 bit. I'm hoping you could help me on this. Thank you in advance.

Hello Taey, and welcome to Seven Forums.

While changing the advanced power plan settings, double check to make sure that your default power plan is still selected. It's a bit to easy to change it by mistake and not notice it. In addition, double check your Battery settings to see if the percentage levels may be set to cause this by mistake.

Hope this helps for now.

hi Brink please check if this works.
