      First reflash the bios, if not ok remove Sound, lan and card reader chip.
      Last week i received one and it could boot normal after remove sound chip

                  Sory, but I have a cq40 with exactly the same simptoms as yours, no power up nor display, only a blinking led. Was trying to flash the bios but no case, how do you manage to flash it, or how are the bios recovery procedures in this model? thanks
