Lenovo G50-30(80G0) screen brightness flashing on the power supply

I have a problem with flashing screen on the power supply in Lenovo G50-30. Everything happens only when the battery level falls below 100% and connected power supply. This problem does not occur when working on the battery itself or when the battery is 100% charged.
This flashing is not very clear but on a white background the screen brightness is slightly flickering.

Re: Lenovo G50-30(80G0) screen brightness flashing on the power supply

Hello Pawell123

Thanks for using the Lenovo forums.


Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal

Hope this helps, let us know how you get on.

"Kraken" great thanks for the help - as soon as I have access to the latpopa I will do what you wrote me.
My problem looks like this - "http://www.youtube.com/watch?v=VXbwWyl3IZE"
Bios have been updated, drivers also -  flickering of screen brightness occurs only on the power supply when the battery drops below 100%
