I have a gateway netbook. Normally when it is plugged in and I unplug it the screen dims. Yesterday it stopped doing that. Now when I unplug it stays at the same brightness.
Just to clarify, it seems as though whether it is plugged in or not, the brightness is like it used to be when I unplugged it (it is dimmed either way).
It's not that important because the thing stays plugged in most of the time, but I am curious as to how this could happen. I just reinstalled Windows on it a few days ago. It is 32-bit ultimate, if that matters. Any ideas?
You might want to try downloading and installing the drivers from Gateway. Windows probably installed a basic Microsoft driver to get everything to function. The problem with this is that those drivers only supports basic functions of the device in many cases.
