Hello everyone. Today I find this inconvenience and for lack of time I go to you to be able to solve it faster. I tell you a Positive BGH Z100 notebook arrived which comes with a 2GB DDR3 1600Mhz RAM to upgrade to 4GB since a beast (or the same beasts of BGH) ironed a 64Bits system and the owner already wants to add more ram , but when installing the new Ram, it does not start without video as if the ram failed or did not have it, remove the battery from the mother, I kept pressing the power button to download but still does not take it. As a last resort I can update the Bios but the official website does not even show the model only z111, z z121tv and z131. I hope you can help me. I just found a bios but I don't know if it will be more updated, I leave this as a last resort.
