Once you are familiar with your device and used to the way
the operating system responds to your work routine, you can
easily detect if the operating system is not working correctly.
For example:
❖
The operating system fails to start after the initial startup
appears.
❖
The operating system takes a long time to start.
❖
The operating system responds differently from the
normal routine.
❖
The screen does not look right.
Unless a hardware device has failed, problems usually occur
when you change the system in some way such as installing
a new program or adding a device.
If you experience any of these problems, use the options in
the Startup menu to fix the problem.
