I had just recently gotten at T61p for work and I have to say it’s a very sweet machine, with all its 1920X1200 pixels. I did have a problem when my machine was running on battery, the sound seemed to choke every 1.5 seconds or so. My friend forwarded me the fix and i thought it might be useful to post this for others experiencing the same problems (i heard it’s not just me). Turns out, it’s the network card driver that’s causing all the trouble. This site has the driver update for pre-vista machines but the driver seems to work on vista as well, i just tried it out myself.
Check it out!
