When updating the system BIOS it is normal for a series of 2 long beeps followed by 2 short beeps to occur at least two times, and the power LED will blink after initiating the BIOS update. During this process the screen will be blank. After the beeps the system will shut down for about 30 seconds, and then it powers itself up. This is normal behavior for the BIOS update.
Note: During this process the LED will be blinking:
- For Notebooks the battery LED will blink white/amber
- For Desktops the power LED will blink red/white
Note: There may be some variation of this process.
