Solved! Error: screen laptop

[qhquang1906]

Hi everybody.
My laptop screen is black when using battery. If using an adapter, it is normal.
Thank you for watching.

So it powers on but only gives you a black screen when on battery, but find when on the charger?

Try this...

1. Go into "Control Panel" and click the "Power Options".
2. Next to the plan that is currently selected click "Change Plan Settings".
3. Now click "Change Advanced Power Settings".
4. In here go and check under both the "Display" section and also the section for when on "Battery" power. Make sure it is not set to turn the display off when on battery. It can happen.

Should nothing in there be the cause, then you may want to check which graphics the laptop is using when on each (battery/charger) and make sure it isn't using different ones. If so, then the one being used when on battery could be failing.

Lastly, if the battery isn't putting out enough power, and in need of replacing, it could also be the culprit. In that case the only fix would be to replace the battery.

Thank you, But my laptop still works when the screen is black. I changed the battery. But it does not fix. My laptop lights up when there's an adapter.

I am assuming you mean it shows the screen rather than lights up, yes?

I fixed this error. I replace anx1121 IC, but it only shows 14 inch screen. My laptop is 15.6 inches

Are you sure the part you replaced it with is the correct one? If aftermarket or a different part then it could cause it.
