I need help with an Acer Aspire 7750G-9810 laptop. The keyboard has mostly stopped working. A few symbol keys and the backspace key work as well as the numeric keypad. The letters do not work at all. I had closed the laptop and when I opened it up to use it next the keyboard did not work. I have tried restarting the computer using normal shut down as well as a hard shut down (holding the power button down until it shut off). I have checked the device manager, it shows it is functioning properly. I also checked the driver, it says it is up to date. The touchpad mouse is working. Anyone have any advice on what to do next? I can use the onscreen keyboard or a wireless keyboard.
