Re: B5400 Touchpad problems win8.1


Today I forwent Lenovo B5400 because the touchpad's problem is very popular.

I exchanged its on Lenovo B590. It's a older model but it's free from defects and a bit cheaper.

Re: B5400 Touchpad problems win8.1

Lenovo .... smells bad, long time since I enter the forum because the laptops bought returned all, and for several months we do not sell notebooks Lenovo.
The problem with touch and detect that ought to be something of electrostatics.
That the only way to repair them properly, would change the tactile with others of better quality, or well said our companion, get isolated.
I'm sure the Lenovo sat knew this.
They try not execute guarantees that costs them money.
In Spain sell laptops, the law mandates that have 2 years warranty. But they only give 1 year warranty. The second refuse to apply it, ripping off customers.
Playing with clients. This repair is not made, let time pass. If you open the laptop for repair, you lose the warranty. As time passes, and as the year goes on, and you have no warranty. Perfect for Lenovo, but bad for the customers...
This I can show proof, Mark_Lenovo

What's DOS?

Re: B5400 Touchpad problems win8.1

I also had problems with my Lenovo B5400's touchpad. I think that I have found solution.


Please do as follows:

1) Install latest Synaptics driver if you don't have

2) Go to your Synaptics driver settings

3) In settings disable all options beside 'Buttons' and alternatively 'Taps' (You have to Disable 'Gestures' and 'Scrolling')

4) Install application two-finger-scroll (1.0.6 is the latest version)

5) In application two-finger-scroll set to run it when Windows starts. Choose your prefered two fingers scrolling (experiment) and you may also set two fingers tapping as middle button.


I understand that touchpad problem is probably hardware problem, but solution I gave is as far by now the best in my case.


Please write if this worked in your Lenovos!
