A real world problem and algorithmic analysis

Problem:
An engineer using Toshiba Tecra M2 laptop, and it is failing on him.The problem seems like either power adaptor or the battery pack, but he needs to determine which before he tried to purchase any replacement. For that, He would like to do simple test with existing ones.

Objective:

fix the problem instead of bringing up to run.

Algorithm Analysis and Design:


0x00000001 --- AC Adapter
0x00000010 --- Laptop Main

Tested Unit:
Parts[0] <---- 0x00000001
Parts[1] <---- 0x00000010

Good Laptop as Instrumentation Tool:
Tool[0] <-----0x00000011
Tool[1] <-----0x00000100


Fix-Laptop(Parts, Tool) return 0-1
DefectParts <---- Test-Part (Parts, Tool)
Go to Dealer for maintainance
done <---- 1
return done


Test-Part (Parts, Tool) return DefectParts
Success = Connect(Parts[1], Tool[0]);
if Success
then DefectParts[0] <---- Parts[0]
else do Success = Connect(Parts[1], Tool[1]);
then DefectParts[0] <---- Parts[1]
else do inspection again ensure no contact issue
else DefectParts <----- Parts
return DefectParts

Solution:

It seems unicast to local vendor would be optimal
algorithm than multicast over the smtp overlay
network in term of complexity, cost and completeness.
Since We need to go to dealer anyway, why do
test there and get fixed part right away ?
