Buzzing/grinding sound

My Laptop (a Inspiron 17R N7110 running a 64-bit Windows 7 has been making a buzzing or grinding noise (for lack of a better term) coming from the upper left corner.  There is also a slight vibration on the left side.  This happens whenever the computer s running, so it's not an audio issue.  Is this a problem with  the cooling system, or something else?  How do I fix this?

About the only thing it can be is a faulty fan or hard drive - based on the origin, replace the fan.

Re: Buzzing/grinding sound

Hi DPicher,

Please run the hardware diagnostics on the system to confirm hardware failure. Here are the steps:

  • Restart the system and immediately start tapping the 'F12' key to enter the 'Boot Menu'.
  • Use the 'Down Arrow' key to highlight the 'Diagnostics' option. Press the 'Enter' key.
  • The diagnostics will begin. Please note the exact error message/code, if any appears on the screen.

The Fan Module is located on the upper left corner. Make sure that the air vents are clean. You can clean them using canned air. Also, update the BIOS of the system and check if the issue still persists. Here are the steps:

  • Click on the below link: http://dell.to/1aKGX1T
  • Download and save the BIOS on your desktop.
  • Once the BIOS is downloaded on the desktop, right click on it and select 'Run as administrator'.
  • Follow the prompts on screen and restart your computer.

Note: Make sure the ac adapter is connected and the battery is charged 10% or above to update the BIOS. Also, disconnect all the external peripherals before updating the BIOS. All the programs should be closed and documents saved.

Please share the results, will take it further from there.

Thanks & Regards
