And if you go with Lenovo, be aware that their T60/T60p/T61/T61p series (and possibly the X-series) are known to sport very high temperatures. Some people have reported temperatures of nearly 90C on their GPU (when idling), which has a direct effect on the overall temperature of the CPU (due to close proximity) and so on. This requires the fan to be on at almost all times (usually low-speed mode). Others have it worse (the laptop literally shutting off in the middle of operation):
Likewise, I've had difficulty with the z60t, which has suspend issues (it doesn't), and occasional atheros flakiness that I have been meaning to bug Sam about but haven't had time to do so as yet. Sadly, the battery failed quite quickly once the warranty expired, so I barely use it anymore, which is something of a shame but left me with a bad impression.

http://unix.derkeiler.com/Mailing-Lists/FreeBSD/stable/2008-06/msg00020.html Many of these laptops emit a strange high-pitch electrical noise which fluxuates in frequency and amplitude; of course, a lot of people can't hear it, which is good for them. This was tracked down to some power saving features listed in the BIOS (of both the CPU and the chipset), which you can disable: http://www.thinkwiki.org/wiki/Problem_with_high_pitch_noises Be sure to look at http://www.thinkwiki.org/wiki/Category:T60p, specifically the very bottom of the page. You'll notice a very large number of problem entries. A lot of them have no real response from Lenovo.
