Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I don't know for sure.. But I would assume you are probably fine... Most newer computers will start shutting down/rebooting when the CPU get's to hot... So until you start getting errors assume all is fine.. My HP Pavilion notebook is a true P4, not even a P4 mobile... and I don't usually check the temp. but suffice it to say that it gets VERY hot on my lap... A lot of the heat is also from the RAM on these I believe... So again, unless you start having obvious errors... I would say you should be fine... If you are concerned, call IBM.. they are generally quite good with customer support...
I would say that as long as the normal range operates in the 40's or high 40's you're OK. Laptops generally do run a bit hotter than tower due to their limited cooling ability, but I think that as long as the 63 mark is a temporary peak rather than a typical condition, I wouldn't worry about it too much. Naturally any app that really works the CPU will cause a temp increase, but as long as you're not baking your CPU for hours at a time I think it would be OK.
As already suggested, you could call IBM if you are concerned. -- J.W.
Thanks again for all the replies, I have a little info to add:
I relocated a room fan to roughly NNE of the laptop and ran the Celestia demo which is very graphics intensive, plus updatedb, plus web browsing, plus playing Soldier of Fortune in full screen (Loki demo) and the temp never went over 52*C,
All of this with Gnome with screen res set to 1024x768.
I should add that the Soldier game was NOT running smoothly, and neither was Celestia (both at full screen) but hey, which $1000 laptop could run those two simulatuneosly (sp?), but everything was usable and a ctrl-alt-f* still gave me a usable CLI, albeit a little slow.
