Thank you to tuyen821991 and hoaca388 for your files. At first I blamed a possible corruption of bios but the problem persists, since the equipment turns off and then if I turn it back on, the power LED flashes (next to the hd LED) with a cadence of about 3 seconds. Also the power LED of the dc jack, alternates the flashing of white light with orange (since it is charging the battery. After a while with this behavior, he manages to turn on the solo. It's a breakdown that has me crazy...
