Since everyone is gonna be a b!tch and rag on you about your room I will join the group that doesnt give a sh!t what condition your room is in and say "Nice laptops." I hope the R50 works out for you in college.
yes, It depends on what Im running and how I run the cpu, lcd, and what I turn off, but its almost always between 4.5-6 hours ( I can get 6.5 if I turn literally everything off, including the LCD) I get 4.5 normally, and 3.5-4 if Im using the CD/DVD Player
Congrats, and enjoy the R50. I have had T42p (First IBM computer) for about a week, and I love it. Don't worry about all the other people in here, you wanted to post some pictures of "Your" laptops, and you did. Just post who's they really are next time, and people won't think of you as a flamer.
