Fix: Windows laptop screen brightness flickering

[javajolt]

If your Dell Windows laptop screen brightness is flickering randomly or when on battery power, then this post suggests methods on how to resolve this problem. I recently bought a Dell Inspiron 15 7537 ultrabook, and was facing this issue. Although I have prepared this post keeping in mind a Dell laptop, this could work for HP, Lenovo, Acer and other laptops too.

If your laptop screen flickers, pulsates or dims and brightens every once in a while, you may see if any of these troubleshooting suggestions help you.

First of all try and identify when you face this issue, when on Battery power, mains AC adapter or in both scenarios. Is it for a particular power plan or for all power plans? Also check if this happen when you enter BIOS and in Safe Mode too. Is your battery very old? Having this bit of information may help you.

You may try these steps in any order. Select the ones which you think apply to your scenario and are more likely to help you.

1] First of all visit the manufacturers website and update the video and graphic drivers, for your model.

2] If updating does not help, uninstall and reinstall the Video drivers.

3] Open Control Panel\All Control Panel Items\Power Options\Edit Plan Settings and  restore the default power plan settings by clicking on Restore default settings for this plan. Do this for all your Power Plans.

4] Change the refresh rate and see if that helps.

5] Open My Dell and Run PC Checkup for your Monitor. If any issues are detected, follow its instructions to address the issue.



6] Open Power Options in Control Panel, and from the left side, select Dell Extended Battery Life Options.



The Battery Meter settings box will open. Uncheck Enable Dell Intelligent Display. Click Apply and Exit.



See if this helps

7] If your laptop used Intel processors, disable the Intel Power Saving Technology. You will get this setting in your Dell or Vaio Control Center.  From the Start Screen search, type Intel HD Graphics Control Panel and hit Enter to open it. Click on Power > On Battery.



You will see Display Power Saving Technology. Disable it, click Apply and restart your computer.
