MorganS:
The problem is in the code you didn't post.

Also, please explain more what you want to do. This isn't Google. You are allowed to write entire paragraphs.

Code:

#include <Arduino.h>
#include <HID-Project.h>

void setup() {
    // put your setup code here, to run once:
  Serial.begin(9600);
  Keyboard.begin();
  while(!Serial) {}
}

void loop() {
    // put your main code here, to run repeatedly:
  Keyboard.println("shutdown -s");
  Keyboard.write('-');
  while(1) {}
}

the output is always ' instead of -

i make 2 hours for find a resolution at the problem but it's impossible to resolve
