Touch pad malfunction in Windows 7 Ultimate for Dell Vostro A860

[xti74]

Hello,

I have a Dell laptop, model Vostro A860. OS is Windows 7 Ultimate. Since few weeks ago, suddenly, touch pad stopped working. By connecting an external USB mouse, everything works fine.
Last week, I discovered that on battery mode the touch pad is working fine. I did not see this from the beginning since the laptop is used only during evenings and was always on power.
So, finally, my problem appears only if the laptop is connected to the power supply. Again, an external mouse is working on both cases.
I just want to ask you if you detected this problem before and if you discover any solution: change the driver, adjust the power settings,...? Is very strange that on battery mode is ok everything.
I'm not sure that is a Windows problem or something wrong with the HW.

Thank you!

Hi Welcome to Seven Forums .. You have a very unusual problem there .. In a way you are lucky cause at least it works on Battery which is handy if you need to take the Laptop out with you .. Now you could try another Driver .. See the Link below .. May help or not the question is do you want to mess with things or happy enough the way things are .

Thank you for welcome and for the advice!

I will try this driver also. Yesterday I found another one, R189727.EXE (specific fot this model, but I'm not sure if it is for Windows 7), but I did not have time to install it.
Very good question from your side ! For the moment I will try by myself to find an answer to this strange behavior. I already contact a local IT company to check what can be done and the answer was very simple: leave the laptop 8 days for a complete diagnose.

I just did a Vista Ultimate 64 bit install on my Dell Inspiron 1525, the touch pad works with the Vista installed driver. In Devise Manager it's listed as a "PS/2 compatible mouse" it's a generic windows driver. I can hot swap between the touch pad and my wireless mouse, on or off battery.

Dell has 2 or 3 different touch pad drivers listed on the driver page. I was going to install a Dell driver but decided to leave it alone.

Hi xti74,

I understand that you have sent the laptop for diagnose and repairs. As the issue occurs only on charging then it seems to be an issue with the AC adapter or charging port.

Most probably would be a charging port and replacing the same should resolve the issue.

If the system is under warranty then please contact me through a private message by clicking on my name highlighted in blue. On the next page, click the envelope icon and provide your service tag and contact information so I may access your system records.

And, if the system is out of warranty then you contact our Expired Warranty Support at the link below:
