Sorry, I don't speak english, and i have the same problem with the touchpad. Your solution isn't clear for me. Can you explain me in detail?

 

Thank you

There are no real solution that works perfectly.
1. Return the cmputer and get your money back.
2. Buy a mouse.
3. Wait and hopefully Lenovo will release a driver that works. (Wouldn't bet on that one)

Re: B5400 Touchpad problems win8.1

I think isn't a software problem. I' m using ubuntu right now and i have the same problem.

I will try to contact to lenovo to get my money back, but in Spain is imposible talk with any operator by phone.

Re: B5400 Touchpad problems win8.1

As I wrote on the M5400 thread, I also got this issue on Linux, which uses different drivers than those on Windows, leading me to believe that this is more of a firmware/hardware issue, not a software one. I did some tests on my Linux box and when I ran evtest while the touchpad gone crazy, seems that the system thinks there is already a finger touching the touchpad. Here is a sample of evtest output; please note that while this data was collected I wasn't touching the touchpad at all. A normal behaviour in this case would be the output waiting at "Testing ... (interrupt to exit)"

 

I cannot understand how this issue passed Lenovo's QA. Is not an isolated one and it doesn't take too long to trigger it. Fortunately I'm not using the touchpad very much, but there are some situations when I have to and this issue is making everything annoying...

Same problem here, i tried uninstalling the synaptics driver then i tried withour windos driver and the problem doesnt go away at the begining worked good but now after 4 months the touchpad is completely unsuable...

 

well its a Chinese company anyway, chinese are famous for manufacturing crap products....i myself should have bought an asus laptop but i swallowed that ''lenovo products are reliable'' crap like everybody and got burnt
