e-Diagtools for Windows can also update the version of e-Diagtools on your notebook’s hard disk. In
e-Diagtools for Windows, use the e-Diagtools menu.
If you have trouble running e-Diagtools diagnostics from the hard disk, you can also run it from the
Recovery CD or DVD. Boot from the CD or DVD and select the diagnostics option.
Interpreting the Results
The e-Diagtools diagnostic program returns test groups, error codes, and suggestions for repair and/or
follow-up actions. The basic hardware test shows a recommended replacement part.
To help interpret the results of the e-Diagtools tests, refer to the following:
• e-Diagtools Support Ticket on page 3-19.
• Replaceable Module Diagram on page 1-64
• Functional Structure Description on page 1-65
This combined information should enable you to determine which of the notebook’s components
require service.
Power-On Self-Test
Note
If Quiet Boot is enabled in BIOS Setup (the default setting), press Esc during boot to see POST
messages.
When the notebook boots, its system BIOS runs a series of initialization routines and diagnostic tests
called POST (Power-On Self-Test). The BIOS will not boot the notebook’s operating system if the
system memory, CPU, DMA, or interrupt controller fails the POST diagnostic tests. POST indicates
progress by a sequence of codes; if an error occurs, the BIOS displays a message and/or issues a
beep code.
Note that not all POST messages indicate a failure in the notebook—some messages are for
information only. You should not necessarily interpret the failure of one or more POST tests as a
hardware, software, or firmware failure. If POST displays an error message or issues a beep code
indicating an error, confirm the problem using other diagnostic tools.
