Hello friend, recently I had bought Acer Aspire 5920 and the function present in this laptop is so nice. I had installed Windows vista operating system. Before two days, I install Empowering Technology and first day it does not create any issue but after that it does not work. I need to solve this technology issue and use this technology without any trouble. Anyone is having knowledge about it then please share it. Any type of help will be appreciates.
