During BIOS update verify that the computer is connected to an AC Adapter.
Disconnect any third party peripherals connected to the computer before performing BIOS update.
Do not turn off the computer during the BIOS update.
Do not restart the computer during the BIOS update.
Note: Plug your computer to a good, working UPS before you update the BIOS. If you experience a loss of AC power or a significant voltage sag/spike during the BIOS flash, you will either have to buy a new BIOS chip or buy a new motherboard.
Clean Air vents:
Check the vents on the computer to see if they are covered with dust and not allowing heat and air to pass through.
Use a compressed air can to blow the dust out of the vents. Be sure to hold the can at an upright (near 90 degree angle) and hold it 15-20 centimeters (6-8 inches) away from the target.
Turn off the System
Remove all power sources: Unplug the AC Adapter and Remove the Battery, or Unplug the Desktop Power Cord.
Hardware Diagnostics Check:
Run diagnostics on the computer. (Hold down the FN + Power button simultaneously).
