Hi anujgupta350,

I would like to know if issue occurs in BIOS. If you have not yet checked, please restart the computer and tap F2 key at Dell Logo to enter the BIOS. 

We can also check in safe mode. Please follow the below mentioned steps: 

1. Restart the computer
2. Tap F8 key repeatedly at Dell logo for windows Advanced Boot Options.
3. Use the up/down arrow key to highlight "Safe mode" and press enter.

No there is no issue when I enter the BIOS or use the system in safe mode.

But there is problem in normal mode.

Also, When I play some video, make it on full screen and then minimise it. Then, the colors just fade out for some seconds.

Hi anujgupta350,

Go to power options and change the setting for Graphics Power Settings from Maximize Battery Life to Maximize performance. Please follow the below mentioned link to go to Power Options: http://windows.microsoft.com/en-US/windows7/products/features/power-management

Also perform the steps mentioned below:

1. Right Click on an empty Space on Desktop and Select "Personalize".
2. On the "Personalize appearance and Sounds" Screen, Click "Window Color and Appearance".
3. Click the arrow beside "Show Color Mixer".
4. Move the Mouse Pointer to move the tab of the "Brightness" Scale from Left to Right and from Right to Left to adjust the Brightness and Click "OK", when you are done with it.

If issue persists, please let us when does the screen fluctuate when it is on battery or AC adapter.

Hi Madhur,

Thanks for replying.

There is no fluctuation in High Performance but its creation issue in Power Saver or Balanced Mode.

Hi anujgupta350,

Does the brightness fluctuation happen when the adapter is connected to the computer?

Create a new user account and check if it is working fine or doing the same thing. This would tell us if the issue is with the user account. To create a new user account, please follow the steps mentioned below:

1. Click Start.
2. In search Type “User Account”.
3. Press Enter.
4. Ensure that it is an Administrator account.
5. Check if it is working fine.

Hi Madhur,

There is no fluctuation problem when adapter is connected to laptop.

I  tried by creating a new admin account.

But the same issue is happening in that account too.

Hi anujgupta350,

To isolate the issue please provide the following information:

1. Does it happen when the battery is low or when it is fully charged?
2. Have you checked with a known good battery?

It happens all the time whether its fully charged or at low battery.

I bought my laptop 8 months back and the issue exist from nearly starting.

Refer service tag no : for product information.

Thanks for  the replies.
