Display Brightness
When gaming on battery power, display brightness automatically decreases to the minimum value in Windows. High performance power profile, all screen dimming options disabled, already tried alternative display drivers and a full system restore.

Hello,
could you please tell us what kind of Dell Laptop and operating system you are using?
Has your system got function keys on the keyboard to increase or dim the brightness?
Regards,
Florian

The service tag is [edit: removed by admin]
It is Alienware 13 R2 i7-6500, 16GB RAM, 512 SSD, VIDIA GEFORCE GTX960M 2GB, WIN10
I just bought it on 18 December
The brightness changes automatically when I am playing games without charging. The problem exists when I enter the game.

Independent on what graphic card is used, still you've tried the suggested steps, right?
Does this video describe the problem you are experiencing?:

The brightness in this video changes at minute 2:49.

I have tried it already. But when I play games, I am using the NVIDIA Geforce graphic card. These links are not helpful at all.

I think yes. The brightness always becomes 0% and it is very annoying

I think the setting works. Not very sure. By the way, Thank you very much.
I want to ask is Dell Power Companion PW7015L - external battery pack - Lithium-Ion - 18000 mAh compatible with my laptop?

Hello,
please let me know, if the setting works on long term.

Kind regards,

There is no problem now when I play the total war game series. I would like to ask is there any small chargers for Alienware 13 R2 or any portable external batteries?

Hello,
there is only a 180W AC-Adapter available for the Alienware 13 R2. All smaller AC-Adapters will not be able to charge the system while it is powered on.
Same applies to the portable external battery stated above. It will may charge your battery but only while the system is powered off.
Regards,
Florian
