Case 3 - Boot Process Fails and Monitor is Blank Case 3 - Boot Process Fails and Monitor is Blank When the power button is pressed, the hard disk drive or fan can be heard, but the PC Workstation does not boot. The monitor remains blank and the status LED is red. HP MaxiLife has detected a hardware error. • Hard disk drive and/or fan can be heard. • Monitor remains blank. • Status LED is RED. • Beep code is emitted. NOTE Before removing the cover, always switch off the display and PC Workstation. Disconnect the power cord and any accessory cables. When checks have been completed, close the PC Workstation and reconnect the power cord and accessory cables. Verify that the PC Workstation boots correctly. When your PC starts up, its BIOS 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. 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. 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.
