Cannot Adjust Power Settings on Your Samsung Laptop?

To be direct the answer is disable Samsung FAST START program.

Samsung’s own software overrides Windows 7 POWER OPTIONS settings and greys out several options, including:


FAST START is enabled by default and it claims to ‘enable’ the laptop to enter sleep mode whatever the power settings. In fact it forces sleep mode by hard setting all the power-off options except the standard ones on the Start menu.  Disabling FAST START it released the options.

To disable FAST START, follow these simple steps

  1. click the START BUTTON
  2. type FAST into the search bar
  3. click FAST START when it appears
    1. click YES on the User Access Control window, if prompted
  5. Have a nice day

    I also have the Samsung NP900X3A, and I remember that I switched Fast Boot off once… suddenly the computer was on maximum power setting, and no longer allowed to change the energy settings. With Fn+F1 I came into the Samsung settings, and there fast boot was definitively switched off. However, I had to switch it on and off again, to be able to change to sleep mode when closing the lid.
    Samsung meddles around with windows and android, but their “improvements” alway turn out to the worse.

    What can I do if I don’t have windows?

    Seems retarded on samsungs part, in order to boot from usb when windows isn’t working, I need to go into windows first.

      If you are not running Windows I suppose you will be out of luck.

    Actually I have just figured out where it is and how to do it.

    You need to go to the Samsung Control Centre by pressing Fn + F1 and the fast start is there to turn on and off. After turning it off you are able to change the power options!

    Hey I am also trying to change my closing the lid options but can’t. I just got the Samsung Series 9 NP900X3A. I have read that its because of the fast start, but if I search that in the start menu nothing comes up about the fast start.

    Plzz help!

      I don’t know the Series 9 NP900X3A but I assume the Samsung power app is the same for all recent Samsung models.

    You know, as a long time admin, it drives me nuts that some piece of software assumes my preferences (like sleeping when the lid is closed and connected to an external monitor). Thank you for that. I KNEW I should have reflashed the bloody hard disk.
