Mouse cursor jumps around the screen randomly

[X220]

I have an X220 convertable laptop but the mouse cursor is driving me mad.  It randomly jumps around the screen; clicks things and generally makes working really hard.  

At first i thought i might have a virus although i have Norton installed.  I have done virus scans with Norton and McAfee in both regular and safe modes.  No problems found.

I have diabled and installed drivers; changed mouse settings; reistalled USB drivers; tried a corded mouse and nomouse other than the touchpad.  Nothing works.

Lenovo support say they think it is a hardware problem; they sent me a new keyboard.  i put the new keyboard in (really easy to do).  No difference.

Lenovo want me to return my machine for evaluation but i use it every day.... I make mony on my computer and cannot affort to lose it for the minimum 4 days max 10 days they want it for service.  If i cannot work for 4 days I might as well go and buy another computer and throw this one in the bin!

Can anyone heplp please??

Does the issue persist when you're running on battery with the charging cable unplugged? For me that stops it. That's not a permanent solution of course.

Hi 

=> Lenovo support => Motherboard !

Thanks, that did it for me as well.

Did they send you one or did you have to send it in? I really cannot afford the downtime of sending my laptop to a repair center.

My warranty included on-site service, so the tech that came in brought it. I'm not sure if they ever send out parts.
