Pressing the power button and all the buttons light up but the laptop does not make the effort to start, and I can't open the DVD drive. Following the downgrade the computer never booted. So I thought that the BIOS was corrupted or incompatible and I did a downgrade to the computer bios as default BIOS through AFLASH2, performing the process correctly. The wifi was enabled in the BIOS and after the update I put the default settings in the BIOS. When updating the BIOS lost wifi function both in ubuntu and in windows. However, this option was not in the default BIOS, so I decided to upgrade to the latest version to see if they had introduced this feature. The best solution to this problem was to disable integrated graphics through BIOS. I inquired and found out it was due to an incompatibility of ubuntu with dual graphics cards. Suddenly I started having graphics problems when connecting the notebook to an external monitor using HDMI on Ubuntu 11.10. Hello, I have a problem with a bad flash of the BIOS.
