This is consequence of the overheating of the laptop. Now we need to disassemble the laptop and rework the chipset (because this laptop is with embedded graphics in the chipset).
First we remove the battery and the power source for safety.
After this we remove the covers of the memory, hard disk drive and the WLAN card. To do this, we need to remove the screws assigned with red circles on the next picture.
Next we remove the hard disk drive by pulling in the direction of the red arrow.
Next we remove the screws from the bottom.
