FRU (Field Replaceable Unit) List
This chapter gives you the FRU (Field Replaceable Unit) listing in global configurations of
AL1922.Refer to this chapter whenever ordering for parts to repair or for RMA (Return
Merchandise Authorization).
NOTE: Please note WHEN ORDERING FRU PARTS, that you should check the most
up-to-date information available on your regional web or channel
(http://aicsl.acer.com.tw/spl/). For whatever reasons a part number change is made, it
will not be noted in the printed Service Guide. For ACER AUTHORIZED SERVICE
PROVIDERS, your Acer office may have a DIFFERENT part number code from those
given in the FRU list of this printed Service Guide. You MUST use the local FRU list
provided by your regional Acer office to order FRU parts for repair and service of
customer machines.
NOTE: To scrap or to return the defective parts, you should follow the local government
ordinance or regulations on how to dispose it properly, or follow the rules set by your
regional Acer office on how to return it.
