Rated. / 5. Based on customer reviews
A single symptom can be listed under dierent groups. For example, No Video can belong to (1) Power-on or
(4) Display; but Flickering when powered should be listed in (4) Display. Or, in another example, a blue screen
can be caused by a driver conict in Performance (4), but it can also be caused by a defective hard drive under
(6) Storage. Therefore, failures that share similar symptoms are noted.
If possible, make a record of the failure symptom, the phase of the boot-up sequence where the failure
occurs, and the most likely location in the failure tree (Table 6-3 Failure classication by boot-up sequence
on page 80 and Table 6-4 Failure classication by hardware devices and mechanical on page 81). This will
help isolate the issue and indicate the next steps. For example, when the computer is running the operating
system, it may experience an issue with (4) Display, (5) I/O devices (keyboard, wireless, and so on), (6)
Storage, or (7) Mechanical components (stuck buttons, thermal shutdown, and so on).
NOTE: “Uncategorized” is used if an issue found is not listed. For example, Bluetooth is oered on certain
hardware congurations; therefore, a Bluetooth issue can be classied under “I/O Device” if needed.
