Is the ThinkPad t22 compatible with windows XP pro? I seem to be having issues with it. My sound is horrible. I know it's not my speakers because I have hooked headphones and external speakers up and they all sound scratchy and fade at times if I open or minimize a program. I first thought it was because my battery is rather old and I was running it off the battery while playing music. I plugged it in and it seemed a little better but still fade and stuff every now and then. Also, it seems to "skip" a little when playing mp3's. This is driving me nuts I have updated drivers and everything. I just wanted to know is there anything I should be aware of with windows XP on my thinkpad? Any special drivers or software? Any important issues? thanks
