laptop battery problem (i think its a OS problem..)
my dad has a dell inspiron 1000 (celeron 2.2ghz, integrated graphics, 256mb ram) and you know laptops are plugged into the wall that the screen goes brighter, and when it is disconected the screen goes darker to conserve batteries? well, my dads laptop does the opposite. when it is plugged in, it goes darker and when it is on batteries it is brighter.
we called dell and they told us it was a faulty battery so they sent us a new larger one and it still does the same thing. I went into the BIOS and didn't find any options to change it and i looked around windows but couldn't find it either.
anyone know how to solve this problem
