Q. PL unit has frozen
Check that all mouse and touch operation has stopped. If there is any
response from either, it simply means that the processing load is large.
Please wait until the task is completed.
Check if pressing the Ctrl + Alt + Delete keys produces any response. If the
unit responds, shut down all tasks and try restarting the OS to see if this solves
the problem.
Check if the HDD unit is being accessed or not. Try to reset or shutdown the
unit to see if this solves the problem.
