TouchPad and Mouse Not working

Hi Al,

When you say 'Touch Pad and Mouse both are not working', are you referring to the touch pad and touch pad buttons on the laptop?
Also, which test did you perform to check the touch pad's functionality?

Try this BIOS update. 
Before flashing the BIOS please check the following:
* No external devices (printer, USB drive, SD card, DVD, USB mouse) should be connected.
* All other programs should be closed and documents saved.
* The AC adapter and battery should be connected during this process. The battery should be 10% or more than 10% charged. 
Click on 'Download File'>> click "Continue'>> Click 'Continue or Yes' on User Account control if prompted>>Click 'Continue' on the Application prompt>> Click 'OK' on Select the folder where you want to unzip the files to (Make a note of the folder location)>> Click 'Yes' on the next prompt for folder does not exist>> Click "OK' on All files were successfully unzipped. >> If the installation wizard does not appear, go to the folder location>> select the Setup file >> Right-click and select 'Run as Administrator">>Follow the installation wizard instructions.  

If this does not help, you can try to uninstall and re-install the touch pad drivers. To uninstall the drivers, go to Device manager and uninstall the touch pad drivers listed under Mice and other pointing devices: select the driver, right-click it and uninstall it. Once done, download and install the Touch Pad drivers. Follow the aforementioned instructions to download and install the drivers. The laptop will reboot after this update.
Reboot PC. 

Please check the functionality of the touch pad in BIOS, press F2 at Dell splash screen and check if the touch pad responds on this screen by clicking Exit (image shown below).

Do write back with the results.
Please revert for clarification. 

Hi,

Thanks for your response. I tried the BIOS update and Driver Update but both still the touchpad is not working. Although Touchpad was working at Dell Splash Screen after pressing F2. Please suggest what should be the next course of action. It is really hard to work only on keyboard without the support of Mouse and Touchpad .

Thanks,

Al

One thing I notice is in the Device Manager, even after uninstalling and reinstalling the driver (R270497), the Device Manager section shows Dell Touchpad Properties as (Windows cannot load the Device Driver for this hardware. The driver may be corrupted or missing). Can this be a reason for Touchpad not working?

Al,

Thank you for the response.

Since the touch pad is functioning in BIOS, it indicates a software conflict. You can try a system restore which will restore the computer to a previous date. System Restore will not delete any data, but, can uninstall any software that was installed during this time. You can refer to this link for the video on how to perform System Restore in Windows 7: http://dell.to/QC8N7G

If this does not help, you can perform PC Restore to restore the computer to factory settings. If you are not able to use the touch pad during this mode, you can use an external mouse.
Note: PC restore will lead to data (pictures, documents, programs, music) loss. Please perform a data backup prior to this step. Please disconnect any external peripherals as well.
To perform PC restore:

• Restart PC, press F8 key 3-4 times when the Dell logo appears.
• 'Advanced Boot Options' menu will appear, ‘Repair your Computer' is highlighted, press Enter (Use the arrow keys to highlight your choice).
• 'Windows is loading files' screen will appear. Wait for it to load.
• 'System Recovery Options' prompt will appear. Specify the language and keyboard input that you want, and then click ‘Next’.
• Log in as a user who has administrative credentials; select the username from the drop-down list, type the password and click OK.
• 'Choose a Recovery Tool' window appears, select 'Dell Data Safe Restore and Emergency Backup'.
• The Welcome screen will show 2 options; 'Restore computer and preserve my new or changed files' and
• 'Select other System Backup and more options'. Select the second option (Select other System Backup and more options) and click Next.
• The next window will show these options; 'Backup Files and folders' and 'Restore my computer'. Select ‘Restore my computer’.
• Select the 'Factory Image' and click ‘Next’.
• The next window will show 2 options; 'Preserve new or changed files before restoring to selected System Backup' and 'Restore without preserving new or changed files'. Select the second option (Restore without preserving new or changed files) and click ‘Next’.
• A prompt will appear stating that 'your computer is about to be restored all data currently on your computer will be deleted and replaced with your       selected Full System Backup. If an Emergency File & Folder Backup was created, it will still be saved in the location you selected'. Click 'Yes, continue' and click 'Next'.
• PC restore will initiate. Click 'Restart'.
• Follow the onscreen instructions to create a user account.

If Windows Vista is installed on the laptop, system restore steps are similar. For PC Restore, refer to this link: http://dell.to/VdTjYQ.

Hope this helps.
