This board has an issue with the chip responsible for powering the discrete GPU NVIDIA GeForce 650M. The screen would go pitch black, HDMI not responding. However the computer would still work.
The chip had been previously reworked multiple times. Probably it needs to be replaced.
The rest work fines. The board comes with fans and WiFi module.
