I have a problem with the laptop. From the week it happens that when you start it after a few hours longer break white image is displayed and flashing drives can be heard from the front panel LEDs, but the white image or shine or dark, but it still is white and nothing else. Only pulling the battery and disconnect from the network for a while helps. It seems as if something is not stykało on a combination of display board. After re-inserting the battery and the laptop is connected to the current work to improve and turn off and turn on and everything is ok until the next time.
