Beep Codes And Text Error Messages

The OptiPlex BIOS is capable of displaying error messages in plain English, along with

beep codes. If the BIOS determines the previous boot was unsuccessful, it displays an

error message similar to the following:

Previous attempts at booting the system have failed at

checkpoint ______. For help resolving this problem, please

note this checkpoint and contact Dell Technical Support.

The blank is filled with a SmartVu code. To research the code given, search for the

indicators; perform thorough troubleshooting before replacing components.
