Thanks for the suggestion. I HAVE tried the external USB keyboard and that keyboard DOES work, but it only works in ONE of the three USB ports on the Lenovo Edge 2-158 laptop which happens to be the USB port that the wireless mouse's fob is inserted in. I've since found that besides the entire keyboard only typing mostly 6's and sometimes 4's when you press ANY key that 1) the touch pad is inoperative, 2) only one of the three USB ports works, 3) when the laptop is unplugged / plugged in, it does NOT correctly display in the right corner of the task bar the battery power remaining or correct volume and 4) even after you've shutdown / powered off the laptop, the little light on the right side of the laptop still flashes as though the laptop is STILL on. This ALL just occurred on Sun 16 Apr 17 for the first time. This seems to be bigger than just the internal keyboard failing unless I have NO idea what I'm talking about.
