Laptop's screen brightness momentary random changes while on battery mode
Solution 1
You will need to turn off the adaptive brightness feature under the power management.
a) Press Windows Key + X, click on Control Panel.
b) Click on Power Options, Click on Change Plan settings under “Preferred Plans”
c) Click on “Change Advanced Power Settings”.
d) Select the Balanced Active option from the dropdown menu.
e) Expand Display, Click on Enable Adaptive Brightness.
f) select OFF for On Battery and Plugged in options
g) Press Apply and OK.
h) Restart your computer.
Solution 2
Specify your Laptop model number.
There is a chance that your laptop may be supporting Automatic Brightness Change (which is inbuilt in most android and windows phones).
Another chance is that a battery management software is regulating the brightness according to the power used by the processor.

Growing-up the same time computers became widely adopted, sparked a great interest and set fire to my curiosity, driving me to explore the framework that defines the operation of these marvelous machines. Diving deeper into the operation of the different stacked computer technologies out there, it quickly became obvious to me that software development is what intrigues me the most. Even though I consider myself a full-stack developer who understands how things really work, I lean towards technologies such as node.js, Java, old-school C, Android and iOS. Most of my free time is taken by the fine sport of Sailing, in which I had several national and international distinctions with the colours of Greece. Finally, other interests include travellig, mathematics and current frontiers of space exploration.

My laptop's screen brightness momentary adjusts when doings several things, like when loading a web page, when scrolling up/down, when maximizing or minimazing a window.
These changes in brightness are momentary. They last for like 0.5 seconds the screen gets brighter or darker and then they get back to normal...
This happens ONLY in battery mode... I tries to adjust some power settings but still the same issue..
Do you think that is a hardware problem ? If so i need to return the laptop cause i bought it yesterday..
I use windows 8.
Thanks for your help!!
