I have been using the E420 since may now and laptop seems to be fine for the most part...EXCEPT
1. is it normal for the fan to have this 1 second surge for no reason? the pc could be doing nothing but the fan would have this surge where it would make this noise for 1 second and then go back to being quiet again.
i read that few other E420 owners were having this same issue but i didnt read any possible solutions to this problem.
2. the brightness is screwed up. brightness level #2 and 3 is lower than 1 and 0. any fix to this?
