Unplug the machine power cord, switch off and on for a few times the upper power switch and the main power switch (located under the front cover) to discharge completely the power supply, plug the power cord and switch on the machine. If still not working, you need to replace the machine power supply (part no.105E19271).
When plugged in and switched on, no sign of life. Have tried with different power leads. Any suggestions? Power supply failure? Is there an internal fuse?
