C-6 Dell Dimension XPS Txxx and Txxxr Systems Reference and Troubleshooting Guide
If the monitor cannot display errors or problems, during power-on self-test (POST) the
computer may emit a series of beeps, or beep code, that identifies the problem. For
example, one beep, a burst of three short beeps, and two more single beeps (beep
code 1-3-1-1) means that the system has encountered a dynamic random-access
memory (DRAM) refresh error condition.
If the system emits a beep code and then fails to boot, write down the beep code and
look it up in Table C-2.
