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.

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.

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 Windows >
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.

You will be warned when battery power is low. If you continue
to ignore the low battery warnings, the Notebook PC eventually
enters suspend mode (Windows default uses STR).
