Hi,
I had a similar problem of screen flickering while on battery power on my Asus TP550. I tried all different power settings on my laptop, but with no luck.
Over time the screen flickering got worst until one day my screen went completely blank (on battery power only) and I could only use the laptop when plugged in.
I decided to buy a £75 donor laptop off eBay that had a faulty motherboard, so I had all the parts available to me to correct the problem. After just a couple of minutes, I discovered it was a problem with the back light on the LCD panel and by replacing the LCD panel I was able to correct the problem.
I was able to test this before swapping over the LCD panel. I switched on the laptop (just using battery power), I switched on my iPhone’s torch and shined it through the back of the LCD panel and was able to see the desktop icons.
I swapped the LCD panel, and this cured this problem. I was also able to sell the parts of the faulty laptop on eBay to make back the costs of buying the faulty laptop.
I hope this comment helps someone as this issue was difficult to diagnose.

Same problem here with my TP550LAB, screen recently started flickering when on battery power and WiFi is an ongoing nightmare. Kicks me off randomly and cannot even reconnect when restarting. Re flickering - I read enough about people with this issue to know that replacing the battery is not the solution. Have you managed to get anywhere closer?

The impression I get from the comments is that the battery is simply not able to supply sufficient power to run all of the components within the laptop. Other components (e.g. HD, processor, etc) don't seem to be affected by the reduction in power, but the screen controller seems to be much more sensitive.
I think that this is a basic design fault from ASUS, which is why replacing components doesn't fix it, they just do enough to get you past your warranty period after which it's too late to complain. :-( Pity they didn't just own up to what the problem is....
By reducing the overall power used (e.g. reducing screen brightness, or deactivating USB charging ports) it seems to be reducing the overall power requirements enough that the screen controller is able to get enough power so that it can function without flickering. I will try similar changes myself in the power settings and see if I can get my own laptop to work better. Thanks everyone for all the comments!

i have an asus X541U and the screen flicker unless it is plugged to the charger.
this is my second laptop x541u because i asked them to replace the first one which is also flickering, now i had a new one and it is still flickering. is it the display driver or in the hardware? thank you!

I fixed it! I was the drivers. I installed a clean version of windows 10 as it installs Microsoft basic display driver. Problem solved except now I could not change brightness. After I started windows updated it found the correct driver from Intel. Installed and problem solved. Hope this helps. The drivers from manufacturers web site would not work at all.

Good I found this post, I suffer the same problem with F555L and the battery replacement was the logical thing to do... but no luck. I will try to upgrade to windows 10 as suggested.
I have another laptop, a bit older, A55, also based on i7, it is heavier but much better product than this cheaper F555.
