The Power-On Self Test (POST)
When you turn ON the Portable Desktop PC, it will first run through a series of software-controlled
diagnostic tests called the Power-On Self Test (POST). The software that controls the POST is installed
as a permanent part of the Portable Desktop PC’s architecture. The POST includes a record of the
Portable Desktop PC’s hardware configuration, which is used to make a diagnostic check of the system.
This record is created by using the BIOS Setup program. If the POST discovers a difference between
the record and the existing hardware, it will display a message on the screen prompting you to correct
the conflict by running BIOS Setup. In most cases the record should be correct when you receive the
Portable Desktop PC. When the test is finished, you may get a message reporting “No operating system
found” if the hard disk was not preloaded with an operating system. This indicates that the hard disk is
correctly detected and ready for the installation of a new operating system.
The S.M.A.R.T. (Self Monitoring and Reporting Technology) checks the hard disk drive during POST
and gives a warning message if the hard disk drive requires servicing. If any critical hard disk drive
warning is given during bootup, backup your data immediately and run Windows disk checking program.
To run Window’s disk checking program: (1) right-click any hard disk drive icon in “My Computer”, (2)
choose Properties, (3) click the Tools tab, (4) click Check Now, (5) select a hard disk drive, (6) select
Thorough to also check for physical damages, and (7) click Start. Third party disk utilities such as Symantec’s
Norton Disk Doctor can also perform the same functions but with greater ease and more features.
Powering ON The Portable Desktop PC
The Portable Desktop PC’s power-ON message appears on the screen followed by a short beep when you
turn it ON. If necessary, you may adjust the brightness by using the hot keys. If you need to run the BIOS
Setup to set or modify the system configuration, press [Del] upon bootup to enter the BIOS Setup. If you
press [Tab] during the splash screen, standard boot information such as the BIOS version can be seen.
Press [ESC] and you will be presented with a boot menu with selections to boot from your available
drives.
WARNING! If warnings are still given during bootup after running a software disk
checking utility, you should take your Portable Desktop PC in for servicing. Continued
use may result in data loss.
NOTE: Before bootup, the display panel flashes when the power is turned ON. This is
part of the Portable Desktop PC’s test routine and is not a problem with the display.
WARNING! Never turn OFF or reset your Portable Desktop PC while the hard disk or
floppy disk is in use and the activity LED is flashing; doing so can result in loss or
destruction of your data. To protect the hard disk drive, always wait at least 5 seconds
after turning OFF your Portable Desktop PC before turning it back ON.
