The right side of my touch pad control button has stopped working

you can control if you attach a usb mouse , the touch panel is off, go to key pad control and put back on

You will probably want to adjust the pressure sensitivity on your laptop's touch pad to alleviate this problem. If you have Windows, enter the control panel from the start menu.

1. START > Control Panel
2. Find Mouse or Pointing Devices.
3. Enter the Pointing Devices Control Panel.
Things can vary a bit in this section. So you should look for anything that deals with Pressure settings or Pointing Settings. One setting should be labeled "Touch Sensitivity." This setting controls how much pressure is required on the touch pad.
-If you move the setting lower (or move the slider to the left) this decreases the sensitivity. It is harder to accidently move the cursor if you brush the touchpad while typing.
-If you move the setting higher (or move the slider to the right) this increases the sensitivity. It is easier to accidently move the cursor if you brush the touchpad while typing.
(Note that in some configurations, these are opposite - left to increase senstivity and right to decrease sensitivity).

Depending on your laptop there may also be a setting labeled Touchpad Pressure. It's a setting that resgisters if you are accidently leaning on the touch pad. It's designed to reduce the chance of accidental clicks or motions. This setting is generally controlled the same way the Touchpad Sensitivity setting is controlled, through left-right sliders. I've found that keeping the touchpad sensitivity low makes it easier to avoid accidental cursor motions. I also keep the Pressure setting relatively high as well. One thing you'll note that if you adjust these settings to far into one extreme or the other, you will have difficulty using your touchpad. Fine tune these two setting until you achieve the results you want.

Download this driver and it will work

left click is membran switch it was fix in motherboard
need to replace it .


for tapping control you can set as per your comfort from
start menu ---> setting ---> control panel ---->mouse
in "Buttons" tab select double click speed and check it right side yellow folder open and close when you tapping

My daughter has the same laptop and I went to Dell's web site and checked on the parts to buy. The keyboard kit that came with a new touch pad would be around $119.oo. She is going to wait until next pay day. Check it out and have a friend replace it, if you do not want to.

is there a touch pad lock button, that locks the pad? if there isn't then there is most likely excess debris or dust or something under there that needs to be blown out with airisol can. If both of those solutions don't work then i would check to make sure the driver is installed for the touch pad. Good Luck. and i hope it works out.

Ok so here goes.... I had the same problem:

Go to the 'start' button and then hit the 'control panel' option, then click 'mouse' then go to 'Device Settings' and then to the 'settings'. When you get to this screen it shows a list on lthe left hand side choose the 'tapping' option and then ok.

Hope it works for you...it did for me.

In windows xp go into start menu, then into control panel then click on appearance and themes, then move your mouse over to mouse pointers click on it , uncheck "enhance pointer precision, and click apply, that will stop the mouse from acting crazy, this will work with dell mouse pointers and most.

   • If the above steps did not help, there is a problem with the system and it will need to be repaired. Click here for repair options.


7. When complete, four squares will appear, allowing users to test the touch screen sensitivity. (Testing is optional.) Tap the "Confirm" button in the lower-right corner.


8. Wait for the the confirmation message to disappear, then tap "Quit," then "Yes" to exit. The unit will shut down automatically to save the settings.
