Confirm the chassis you are working on before you start to troubleshoot. Subtle differences among
chassis may complicate the troubleshooting process. Refer to the system‐specific documentation to
verify the chassis type and for specific instructions for removing and replacing components with that
chassis.
Types of Components
The components of a Dell notebook are classified into two types:
•
Field replaceable units (FRUs):
o These are deemed replaceable through the services of an onsite engineer.
o Typically, FRUs include the system board, the video card, the audio card, the network
interface card (NIC), the touchpad and the LCD. In most cases the components mentioned
are integrated into the system board.
o FRUs also include internal memory, if applicable.
•
Customer replaceable units (CRUs):
o These can be easily accessed, removed or substituted without compromising the integrity of
the system. Exceptions to this would include internal system memory and any internal or
non‐removable drive, if applicable.
o CRUs include the keyboard, hard drive, memory modules, mini‐OC cards, Bluetooth cards,
modem daughter card, coin‐cell battery, main battery, modular drives, external drives, and
the AC adapter.
NOTE: Component classification of CRU or FRU depends on the system you are troubleshooting. This
classification is a fairly accurate indicator as to which tasks are easily and intuitively completed versus
those that require the skill and knowledge of a trained engineer. Always check the online service manual
to reconcile the work required with the type of work you are comfortable completing.
