Just got this as a freebie. Plug it in, hit power button. All the LEDs on the touch control panel light and stay lit. The charge LED blinks fairly quickly and the Caps and Scroll Lock Lock LEDs are blinking slowly. The extended capacity battery blinks one of its four LEDs when its test button is pressed, but it wouldn't do anything on just the battery. Nothing on the display, no backlight, nothing. The hard drive has been removed but fortunately the bracket's in the bag, a bit bent bit fixable.
