This chapter gives you the FRU (Field Replaceable Unit) listing in global configurations of TravelMate α 550.  
Refer to this chapter whenever ordering for parts to repair or for RMA (Return Merchandise Authorization).
Please note that WHEN ORDERING FRU PARTS, you should check the most up-to-date information available 
on your regional web or channel. For whatever reasons a part number change is made, it will not be noted on 
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.
