DigiPoS PowerPoS Technical Manual
Peripheral Component Check
Once all diagnostic tests and voltage tests have been completed, it is necessary to
establish that the peripheral components of the system are not faulty and causing
apparent motherboard failures or preventing the DigiPoS from completing a successful
boot. Replace each key component using the following the procedure.
•
Power down the system.
•
Using full Electrostatic discharge (ESD) precautions remove the memory, hard
drive, floppy drive, CD ROM and any expansion cards installed.
•
Re-Install each component individually, re-booting the DigiPoS each time until all
components have been refitted or until the suspect device has been identified.
If none of the devices are found to be suspect, power down and replace the standard
peripheral devices and move to 1
st
level fault finding in the next chapter.
