Touch pad not working on Lenovo T400

[JanetBiggar]

Here's the output I got, however I have my USB mouse plugged in. I will try to see if I can repeat this without having the mouse plugged in:  Like when I went into the menu there is no device name in the various items listed for the touchpad, only the mouse:

I: Bus=0003 Vendor=045e Product=00d2 Version=0111
N: Name="Microsoft Microsoft Notebook Optical Mouse with Tilt Wheel"
P: Phys=usb-0000:00:1a.0-1/input0
S: Sysfs=/devices/pci0000:00/0000:00:1a.0/usb3/3-1/3-1:1.0/0003:045E:00D2.0001/input/input6
U: Uniq=
H: Handlers=mouse0 event4
B: PROP=0
B: EV=17
B: KEY=170000 0 0 0 0 0 0 0 0
