Ideapad u310 touchpad issues when plugged in to the power outlet

2012-10-24, 11:43 AM

Hi, I've just bought a IdeaPad u310 and I'm having trouble with the Synaptics touchpad when I plug the computer to a power outlet.

 

When it's on battery only, if I keep my finger on the touchpad the pointer stands still, as it should be. But, I I plug the computer to the power outlet, when keeping my finger in the touchpad, the pointer jumps, making extremely annoying to use.

 

Does anybody else have the same problem?

Hi fernandojs,

 

Welcome to the community.

 

Your issue is concerned to improper functioning of the touchpad ,while plugging in the Power adapter.

 

In order to resolve this please re-install the touchpad driver from the below web link:

As you are experiencing Touchpad not works properly while connecting with power adapter.

 

To diagnose, I would suggest you to please un-install the Synaptics Touchpad Driver, after that  re-install the Synaptics Touchpad Driver and Bios of your system from the below mentioned web link.

Afterwards, please restart the system and check whether the issue gets resolved.

Re: Ideapad u310 touchpad issues when plugged in to the power outlet

I followed the steps mentioned by you. uninstalled and reinstalled synaptics touchpad driver. then flashed the bios with the downloaded file "65CN21WW" which happened without errors. when the system auto-restarted, the problem persisted. As earlier, the problem occurs only when plugged in. Working with battery, the touchpad works fine.

Another observation: When plugged in, the touchpad stutters if I keep the laptop on the table. However, if I lift it slightly and keep my hand under the base, then the touchpad works smoothly. Seems like there is some electrical interference or a hardware issue. Can you please help urgently!

I thought that i solved this problem, but:

 

All right, the problem goes away   when    you touching the iron cover of laptop!

as soon as, you stop touching the iron cover of laptop - touchpad begins buggy/jumpy work

 

it's happens, when power adapter is plugged

if power adapter is unplugged - it's ok

This has NOTHING to do with the Driver. If you uninstall the touchpad driver and use the basic Windows one. Its still the same.

What I found is that with some power sockets the problem doesn't happen! I am guessing that If you are using an un Earthed power socket then you'll get a jumpy mouse pad.

VERY VERY Poor from lenovo! I'm lucky that I don't have the problem at home, but I have seen the problem when I have plugged in at work.! Any suggestions on why this is happpening Lenovo?
