N5110 touchpad left mouse button not working

I had to hit F12 to get to boot options and went through "Diagnostics".  It did actually fail diagnostics on hard drive with the following error:  

Code 2000-0142

validation 6982

Hard Drive 0  Status = 7

I went ahead and stopped the diagnostics at that point and tried the mouse and the left mouse button was still not working.  

Hi abbywitz

Good you have updated the touch pad drivers on the system. Since the left button is still not working, would suggest one step to be performed. To perform this step shut down the system completely, turn on the system and immediately press F8 to go to advanced boot option. In this screen using down arrow key select “Repair your computer” option. It may take a couple of minutes to go to the next screen. Here please use the left button key of the touch pad to see if the system responds. By this step will know if it is mechanical issue. Please reply with the status of this step to help you further.

Thanks and Regards,

Hi abbywitz

Thank you for the service tag information. Since you have also informed about an error for the HDD and also the test was stopped, I request you to do a thorough test on the system.

Restart the system and at the dell logo tap the ‘F12’ key, once every two seconds. On this screen select the option ‘Diagnostics’.  This will run a complete test on all the hardware components of the system.  On this screen you will also have an option to select a particular component to test. Please run test on both touch pad and HDD. Do not use the touch pad keys to select the component. Please use arrow keys on the keyboard to navigate the screen.

Please reply to the post if the touch pad keys worked, also if there is any error message for the HDD. Make a note of the exact error message if it pop-ups while running a test on the HDD. The status will help me to decide if any part needs replacement.

Thanks and Regards,

Here is the latest result (note that this is actually my mom's laptop, I am just trying to help them out and no longer have personal access to the computer):

We did the test, and we got the following info about the Hard Drive.    We never got to the part about testing the "touchpad and the HDD"
 
It said   Error Code 200-0142
           Validation 6982
        MSG-Hard Drive 0-S/N   S2TBJAOC296479     self test unsuccessful status=7
 
Then it did a Repair Startup  and said it did 1 attempt
System Disk= 1 device 
Hard disk 0
# of root causes= 1
Auto chk= 0
Error code= oxo on a bunch of stuff

As per the warranty, I will arrange for an onsite technician to replace the HDD and also the palm rest on the system. Please send me a private message including email address, address, contact number, alternate contact number and best time to call.

Thanks and Regards,
