If your Dell D600 laptop's LCD screen will not remain upright when you are using the computer, faulty screen hinges are the likely culprit. Over time, the hinges can become damaged or simply worn out and need to be replaced. Worn out hinges are usually caused by opening and closing the notebook too fast and leaving the LCD at angles other than the closed or upright viewing positions.
Although replacing the hinges on the D600 is not really a task for beginners, users who have a basic knowledge and understanding of computer hardware can usually perform the repair in about an hour.
