Can't adjust display brightness

jtpice9 -

I too registered on this forum to say thank you for your solution - it worked brilliantly! After tediously searching numerous forums, I finally found a solution that did the trick. Thanks so much!!

jtpice9, same as all the people above me. I tried everything and was just about ready to return my laptop before finding this thread. Worked like a charm! I have no idea how you figured that out but it definitely fixes the problem.

I just bought a Toshiba Satellite L850D and I couldn't adjust the brightness. Also, whenever i put the computer to sleep it would become dim when starting it up again. So incredibly frustrating. How have they not fixed this issue by now?

Bumping this for others who undoubtedly have the same issue. Thanks again!

Sounds bizarre, but the adjust display brightness should reappear.

To everyone who this helped, please help me! I have an hp dv5t lap top with the same problems can adjust brightness. I did what jtprice said, but when he says "the adjust display brightness should appear" It should appear where?? I don't see anything. I've done it a few times now and I just dont know where it should appear. Please help.
