A user reports that she cannot select information on her PDA's screen. She had not used the device while she was on vacation.
What should you try first?
1. Replace the screen.
2. Replace the stylus.
3. Replace the battery.
4. >>Recalibrate the device.
Explanation : The most likely problem is that the device needs to be recalibrated. A Personal Digital Assistant (PDA) can lose its calibration if it is powered off for a long period of time. You calibrate the device by using software that prompts you to tap the boundaries of the screen so that the operating system can calculate where the stylus is pointing.
You should not replace the stylus. The stylus is a pointing device and is most likely not the cause of the problem.
You should not replace the screen before attempting recalibration. If recalibration does not work, you might need to replace the screen.
You should not replace the battery. If the battery is dead, the device will not power on. The problem the user is having is that the operating system is unable to calculate screen coordinates correctly. Therefore, the problem is either with the screen's sensitivity or with its calibration.
