Beep Codes

Fatal errors that occur during POST are communicated through a series of beeps. All beep code
errors, except beep code 8, are fatal errors and do not allow the notebook to continue to boot.
If beep codes occur during POST, check the items in the Problem Checklist (at the start of this
chapter), verify that all the hardware is set up properly and securely connected, and try
rebooting. If you still get a beep code, go to the section "If You Need Assistance" at the end of
this chapter.
Beep Codes are listed in the following table.
