If you are unable to change the contrast with the 'fn' key and the brightness controls, usually represented in the top row of keys as a sun icons, one brightens, one dims. You may have a bad brightness/contrast inverter in your display. It's a small circuit board in the display that controls the brightness. They do fail. You can find them for most models but depending on your technical ability, they can be a little tricky to change.

Remove the battery and power source. Remove the RAM and hdd. Power up with the power supply and it should do something. If it does, replace the RAM and hdd it should now restart. If nothing, check the GPU.

I wonder if the motherboard has bluetooth integrated or I have to put an external bluetooth devise


One way to find out:
Click on the start button > right click on 'computer' > choose properties > (top left) device manager > you will see a list of drivers
Bluetooth should be near the top
IF you don't see Bluetooth, you will need to purchase an external Bluetooth receiver.
