Screen Brightness Needs Plugging In Eachtime
Posted: Mon Jun 04, 2012 11:55 am
Hello.
I have an IBM Lenovo T61 and the problem is when I'm working on it running on AC Power and the power goes off and I put it to sleep or anything, whenever I put it back from Sleep to On mode, it just keeps the screen brightness dull as it was while I was using it on the battery, however the AC is now plugged in. So, what I do is, I unplug the power, the laptop screen blinks to full brightness and then back to the battery powered screen brightness setting. And the I plug it back in, and it's back to the full brightness that has been set for AC Power.
I would like to know as to whether it happens to anyone else as well. Is there any driver issue or why or how it happens and how to fix it.
On a separate note, the last time I had a question, this website was very helpful, the people here are great as well. Thank you for running a great forum, people. Have fun!
