Lenovo mouse stopped working

I bought a Lenovo Laser mouse with my laptop, which seemed like it was pretty cheaply built (surprising for Lenovo), but I thought I'd be open-minded and try it out anyway. Well, a week later, it stopped working. I can't move the cursor in Windows XP, but the buttons still work. I can click on windows directly under the immovable cursor and I can scroll in large browser windows using the wheel. The red light inside the middle mouse button is lit (indicating that the device is receiving the +5 V power from the USB port). I thought it might be a driver issue, so I tried disconnecting and reconnecting and rebooting multiple times, and going through the New Hardware Wizard but it still wouldn't work. I even tried different ports and different USB buses. So then I tried Linux. Linux immediately recognized it as a USB Lenovo Laser Mouse in the dmesg system log, but the cursor still wouldn't move in X Windows. Like in Windows, the buttons still work, though. So I tried the ultimate test: # cat /dev/input/mouse0

I moved the mouse around and saw that nothing was being outputted in the terminal window. Then I clicked the buttons, and there was ASCII character output (TABs and line breaks, but still output nonetheless). This leads me to think that it's a hardware problem instead of a software problem. My other Logitech optical mouse works great on this machine. What should I do?

 

Umm, yeah, I think you've pretty thoroughly diagnosed that its a hardware problem.

What you should do depends on whether the mouse is under warranty; if it is, then contact warranty support. If it isn't, then throw it away or recycle it and either buy a new mouse or use the Logitech optical mouse.

Give my regards to Davy.

 

Is it under warranty? If so give Lenovo a call and see if they can exchange it for a new one.

Doh! Lew beat me to it.

BTW - Nice job with the diagnosis. From your steps you must be into Computer science
