An Object Laptop is having fields Hard disk, Processor,RAM, and Capacity.
Requirement is to populate field Capacity as 'Low Capacity' when 
Hard disk < 40GB, Processor < 2 GHz and RAM < 1 GB  whenever record is Inserted/Edited. 
I am facing issues when I write trigger for edit case, I am not getting how to compare trigger.oldMap and trigger.newMap here to populate the Capacity field only when it is edited to subsequently meet the criteria. 
Please suggest solution using Trigger Only (as I want to do this by Trigger and not by Workflow Rule or Process Builder). 

Thanks
