DELL 15R 5521 default bios settings

Hi moe313,

Here are the steps to reset BIOS settings to defaults:

• Power off the computer
• Restart the computer, tap ‘F2’ key on the Dell logo. This will take you to the BIOS screen
• Press ‘F9’ key once, highlight ‘Yes’, press ‘Enter’
• Press ‘F10’ key once, highlight ‘Yes’, press ‘Enter’
• This will reset BIOS to its default settings.

However, would like to inform you that this may not take care of the overheating issues. I would suggest you to try the following steps.

Ensure that the air-vents are clean:

• Check the vents on the computer to see if they are covered with dust and not allowing heat and air to pass through.
• Turn off the System.
• Unplug the power cable from the back of the system.
• Use Compressed Air to blow the dust out of the vents.

Note: Please use compressed air can. When using compressed air can, use the can according to the directions on the side of the can as you can cause damage to the computer if used incorrectly.

Would also suggest to update the BIOS of the computer to the latest version from Here  

Note: Before updating BIOS please ensure that
*Battery is 10%> or >10% charged.
*Adapter should be connected.
*No external devices should be connected.
*All other programs should be closed and documents saved.

Hi APPU S,

i already did this steps before, but the problem of the touchpad overheating is not solved. some people told me because of the processor, gpu, or the bios chip which is under the touchpad.
so please can you help me to solve the problem of the touchpad overheating.
