Lenovo Notebook problem - Mouse cursor jumps to top-right corner

[mabrowndog]

After a few solid and mostly satisfied years with my Lenovo x120e, I jumped at the chance to snag an x140e for $300 a couple of weeks ago.
 
They redesigned the Synaptics TouchPad for this and other models, and I'm not the only one who's bitched about it, as several YouTube videos will attest. In a nutshell, they got rid of the two bottom buttons (left & right) and the pad is now a depressable platen with the button functionality built in. Unfortunately it now requires a shitload of ergonomically incongruous force to press this thing down (I have arthritic thumbs)... but this isn't what I'm posting about.
 
I'm here to talk about another issue wherein the mouse cursor randomly, repeatedly, sporadically and inexplicably jumps to the upper-right corner of the screen. If I try to move it away, I can swipe it maybe 3 or 4 inches before it happens again. Over, and over, and over. Looking online it appears this issue has been ongoing since 2010, and there is no solution that I've been able to find. Never had any problem like this with my prior Lenovo.
 
Note that most of the discussion in that linked thread pertains to touchscreen functionality and/or drivers, and my model has neither.
 
Any ideas or assistance would be greatly appreciated.

Lenovo infected most of their Thinkpad models with touchpads that also omit true mechanical buttons and their drivers, while updated several times, also have similar issues...in the case of my E531 attempting to right click is a considerable adventure, also dragging and dropping anything is simply impossible. Fortunately I very rarely actually use my laptop on my lap...my solution was

As small as a wireless mouse can probably get without ruining the ergonomics, blue track laser works on anything but a glass surface, receiver is a ministub you can keep in a laptop USB connector, easy switch on underside to preserve battery, scroll wheel handles up/down and horizontal scroll and it, of course, runs off the standard MS mouse drivers...avoiding the Synaptics drivers that are likely to be the cause of your frustrations. For $13 bucks is a useful addition whenever you can use it.
