NOTE: 1. To perform this subtest, connect the AC adapter.
2. While performing this test, don't turn off the power by any means.
If the power is turned off, there is a possibility that the machine may not start.
This subtest checks the operation and compensates the position of the digitizer.
If this subtest is performed, the computer will reboot in order to rewrite the
program of the digitizer.
Therefore, it takes time for a while until the test starts.
Don't turn off the power by any means during this operation.
1) In the case of the model which carries both the digitizer and the touch
panel, perform the following Step1.
2) The model which carries only the digitizer (without touch panel) performs
only the functional check of the digitizer automatically.

Windows operation.)

order to rewrite the program of the digitizer again.
