Hey, My thinkpad t61 makes a high frequency sound, pipipipipippi, not very loud. Funny thing, when I stick in the usb mouse, it's gone... I only have this issue when on battery. Suggestions for solution? Is it right that there is one fan in the T61, on the left of the keyboard? Then a other noise source might be the hdd on the right. It's not that my T61 is very noisy, it isn't very silent either. Maybe I could change the hdd.
