Hi, It was has been around 3 weeks since I bought my Dell Inspiron and since the past week, I'm unable to change the brightness of my laptop. I didn't know if it was a hardware problem or because of the windows update. So I waited till the next Window update, that is today. I still cannot change the brightness, making me feel like it probably doesn't have anything to do with the windows update. I have updated all the drivers mentioned in the supportAssist, restarted my laptop countless number of times but to no avail. To add in a little more detail, the brightness increases by (a very) small amount when I plug it in. It also kind of fluctuates when it is close to 10% Please help me out with this. It is hampering my daily work and I want it to be fixed asap. Thank you very much.
