First things first, you'll have to explain what happened, Secondly you must give the customer the option to choose whether he/she would prefer to temporarily take the laptop and schedule another time to have the hinge be repaired as you can provide the reason that you have prioritize to fix the functional aspect of the laptop rather than the cosmetic issues of the laptop. Putting yourself in the shoes of the customer whilst picking your statement would help to alleviate the concern or complain from the customer.
Well, you didn't say what language, so here's in Java:
public static void PrintShampooInstructions(int numCycles)
{
if(numCycles < 1)
System.out.println("Too few.");
else if (numCycles > 4)
System.out.println("Too many.");
else
{
for(int i = 1; i <= numCycles; i++)
{
System.out.println(i+": Lather and rinse.");
}
System.out.println("Done.");
}
}
And also in an image, in case you can't really see it
