Notebook Operating System and Recovery

I have purchased my Spectre x360 back in 2015,  and i have been using it for less than a year. So far, the laptop experience have been rather satisfying. Apart from experiencing minor glitches initially, the updates helped and the laptop worked just fine and smoothly. Though, the speakers stil have rattling sound when played loudly. 

Until recently, couple weeks back the laptop went haywire as i was doing my assignments. Without any signs to indicate any mechanical problems, the whole system just shut down. i couldn't switch it on, nor could i even charge it.

So i have called up the service centre, and since it is still under warranty, they have replaced the motherboard. On the bright side, I did not lose any datas or files. However, I have discovered my case wasn't the first to happen as there was one earlier case which was much severe. The laptop's motherboard literally burnt. The bottom part was all black and all data was lost

. The following image was the default in my product that has occured recently. 

Hope to receive advise and any precautionary steps to avoid this mishap. Thanks.
