Hi,
I have a Lenovo Laptop. Recently I was burning a DVD in Nero. In the middle a Power Calibration Error appeared and the it closed. My DVD was wasted. I thought to restart my laptop and try back. But due to some reason the system was hanged. I had turned off the same forcefully. Now it not turning on. Is it safe to remove battery if the laptop is connected to AC outlet. I worry that some hardware error has happened. Other thing I want to know the types of desktop screen available in the market and can I change the assignment of a key on the keyboard by another. I have a desktop system also connected to a plasma monitor. I need some ways to clean the screen.
