Hello,

For the last few months, my computer has been subject to an irritating hardware fault. The touch pad seems to be failing, which means the mouse clicks itself between every 1 - 5 seconds. This makes it extremely difficult to navigate a web page, type anything into a dialogue box, or do pretty much anything on that computer. The computer is a Dell Inspiron 6400 laptop with Windows Vista. What is really confusing with the problem is that any mouse I plug in acts in a similar fashion. I am unsure whether it is some mouse driver/ software problems, or if it is a hardware problem.

The problem started in May 2010 and I discussed the possibility of it being a virus with a really helpful member called Myrti. She concluded it was not a virus and I should have a look on the hardware forums for additional help. The problem will start as soon as the desktop appears, and will persist whether the computer is connected to the internet or not.

Other details which may help:

-- The laptop is running off the mains, the battery died a while ago
-- I do not use the laptop often due to the problem, I would use it a lot more if it worked
-- I use internet explorer
-- I have opened the computer in the past after the problem initially occurred. I removed all the dirt under the touch pad but the problem persists
-- I have reinstalled Windows, but the problem persists
-- I have plugged in a ball mouse, and a laser mouse, but both act in the same way the touch pad does.

Thank you to whoever answers this, it would be a real live-saver

That is a perplexing problem, sounds like its possible something on your motherboard is going out. Im assuming both the aftermarket mice you tried are USB??

Maybe try updating the touch pad drivers. Here is the link to the driver update: http://support.dell.com/support/downloads/...p;fileid=188272

the_patriot09 - Both mice I used were USB, not the older circular jack types. If the motherboard is going out, is it possible to get somebody to fix it? Or is it a case that I'll need to replace it?

killerx525 - I will check that out, thank you for sending me the link...

eeeh its feasible to replace the board, however, not practical, your only 2 options would be to order one from the manufacturer, who may not make it anymore, or find a used one off of ebay-which may or may not work, as laptop motherboards are custom fit for each specific model laptop. I would, like killerx suggested, uninstall and reinstall the drivers for the touch pad, as well as uninstall and reinstall the USB drivers as well. Tell me, do any other USB devices give you any problems?

I've downloaded the driver you suggested and it didn't fix the problem, it just helped me deal with it. When I installed it and rebooted the PC, the Synaptics Pointing Device icon in the tray appeared. (I hadn't seen it since I installed vista). I had a look around and it brought up the device details. Curiously enough, the interface was telling me that I was holding down the left keypad button, which I wasn't.

I've set the device so that the buttons are turned off but the touchpad is. There is also an option to turn off the touchpad entirely when you attach a USB pointing device. The reason why the mouse was acting similar to the touchpad when I inserted it was because the touchpad and buttons had not been disabled. So at the moment, I'm having to deal with just using the touchpad by tapping it, and I have designated the top left corner of the touchpad to be the right click, when I hit it.

I know that it is the left touchpad button, not the driver or motherboard, everything is fine, apart from scrolling pages when I need to drag the mouse.
Is there a way I can fix this button?

Thank you,

Struanmcd

Not exactly sure, but maybe take out the left touchpad button and put it back in again.

if you go that method, make sure you clean it out. So if you disable the touchpad and buttons, will an external keyboard/mouse work?
