Hi Allan, All ready took the Laptop to an authorized technician, they discover the problem with the Processor. And to the other question you ask me No it wasn't, normally using it, reading a Word document, closed it and put to sleep the Laptop as soon as the document normally closed. The technician said that probably there is some type of mark in the processor that always tell him that the Laptop is in sleeping mode. They need the datasheet (so I downloaded two of them) to do some research trying to reset that mark.
Thanks for your answers but no solution till now.
