My old laptop display stopped working several years ago, and I recently decided to try and fix it once again. It's an old, very large sony viao circa 2010?? Well the battery is dead, and lost somewhere, so in order for it to even turn on the power cord must be connected. When the power button is pressed the laptop will turn on, and the inside will start whirring, but the screen doesn't even turn on. Is there anything I can do to repair it in its current state? Or salvage the parts to put together another laptop?
