Hi,
Try this for unique:

for (laptop__c lap:laplist){
   if(!recordid.contains(lap.Harddisk__c)) {
       recordid.add(lap.Harddisk__c);
       system.debug(lap.Harddisk__c);
   }
}

And let me know if it work for you.

Hi,
better to put debug log inside the for loop:

for (laptop__c lap:laplist){
   recordid.add(lap.Harddisk__c); 
   system.debug(lap.Harddisk__c);
}

Thanks
