Startup Errors - HP Vectra VL410 Troubleshooting Manual

Startup Errors

Power-on Self Test
When your PC starts it performs a Power-on Self Test (POST) to test your hardware configuration for
any problems. If a problem is detected during the POST, an error is displayed on your PC's monitor.
Pre-boot Diagnostics
If, however, your PC is unable to display an error message (for example, when you graphics controller
has failed), it will emit a buzzing sound. This is the pre-boot diagnostics feature. Immediately after the
buzzing sound, a series of beeps is emitted.
If you hear a series of beeps, you should count them as this will help you detect the cause of the problem.

Please note that for Memory (code 3), Video Card (code 4), and PnP/PCI (code 5) errors, e-Buzzer will
only detect them after a 15-second timeout.
If you miss the beep code, turn off the PC by pressing the on/off power button for five seconds or more,
then listen for the signal again.
The e-Buzzer, as well as emitting a beep sequence, also encodes troubleshooting information (such as
the PC models, serial number, and failing component) into a coded audio signal. During a support call,
this coded signal can then be decoded by the HP Service Provider to provide immediate and effective
assistance.
For more information on BIOS beep codes and BIOS error codes, refer to the Technical Reference
Manual for the HP Vectra XE310 PC, available in PDF (Adobe Acrobat) format on the HP support web
site at: www.hp.com/go/vectrasupport.
