brightness

once in a while, the screen brightness stops responding to any reason, and stays on full brightness..

for those of you that have HP Envy, you know what this means... battery suicide.

the FN+* controls don't work. i also tried going in to power settings and adjusting all modes brightness to low wend of spectrum, after saving, it has no effect..

i suppose i could try rebooting as i always just put my laptop to sleep :/

anyone came across this ?

How to compare old laptop to new laptop?

I hope this question doesn't get closed at once :) I have an old laptop, a Compaq NC4200, which is going its final laps around the track these days. Battery is dead, and everything kinda runs slow. It also has only 1GB of memory, and even though I don't know if it can take more, I probably wouldn't… >>> More
