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):
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:
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
Draw your own conclusions.
