IMPORTANT! If warnings are still given during bootup after running a software disk
checking utility, you should take your Notebook PC in for servicing. Continued use
may result in data loss.
IMPORTANT! To protect the hard disk drive, always wait at least  seconds after
turning OFF your Notebook PC before turning it back ON.
WARNING! DO NOT carry or cover a Notebook PC that is powered ON with any
materials that will reduce air circulation such as a carrying bag.
Before bootup, the display panel flashes when the power is turned ON. This is part
of the Notebook PC’s test routine and is not a problem with the display.
Powering ON the Notebook PC
The Notebook PC’s power-ON message appears on the screen 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 [F2] 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.
The Power-On Self Test (POST)
When you turn ON the Notebook 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 Notebook PC’s architecture. The POST includes a record of the
Notebook 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 Notebook 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.
Self Monitoring and Reporting Technology
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: click Start > select
Computer > right-click a hard disk drive icon > choose Properties > click
the Tools tab > click Check Now > click Start. You can also select “Scan ...
sectors” for more effective scan and repair but the process will run slower.
