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?

Yes, the E420 stays cool and quiet, but sometimes the fan kicks on to cool things down, it is normal.
Also the screen problem is normal and has been fixed and then unfixed with updats that you can fund at lenovos support page, look up the drivers one at a time.
