BIOS Recovery Utility
If your computer loses power and beeps constantly but does not boot when
power is restored, the
BIOS settings may be corrupted. However, these
symptoms can be caused by several different problems. Before you restore
the BIOS, check the
beep codes and diagnostic lights to see if a specific
problem is identified. Otherwise, perform the following steps to restore the
BIOS:
1
Turn off the computer and disconnect it from its electrical outlet.
2
Go to a different computer that is working properly, and download the
BIOS update utility for the computer from the Dell support website.
NOTE: After you download the BIOS update utility, generate the BIOS
recovery utility. To generate the recovery utility, you can use any
functioning computer. You do not have to use a computer of the same type
or model as the malfunctioning computer.
