Helios 300 (G3-572) random shut offs with lines on screen and unable to turn on when on battery

I have above-mentioned issue with my Helios 300 (G3-572-7703).

On battery (around full charge), while reading my lecture slides during my university classes, my laptop suddenly shuts off and lines appeared on screen. When I tried to boot it up again, the keyboard lights up for 5 seconds and shuts off. Then it restarts itself for 5 seconds and turns off again repeatedly.

When I close the lid, the reboot loop stops. So I press power button and same problem above ^ happens again. 

However, if I leave it alone (lid closed) for about 10-15 minutes, the problems stops and I can enter my laptop with no issues, and resume reading my slides. But, after 10 minutes of reading my slides, the screen goes black with lines and shuts off again.

So I went home and charged it up fully for about 10 minutes without attempting to turn it on. After turning it on, no problems whatsoever, I could play games like Tom Clancy's The Division for more than 3 hours and surf youtube and read documents into the long hours of the night. Luckily, I managed to backup some of my important university data in case it happens again.

So yesterday morning, during my lecture classes, it happened again (auto shut off, turns on and off by itself) while on battery. So I did what I did last night and charged it up for about 5 minutes and so far, I could use my laptop and make notes for my lecture slides with no problem.

I have since sent it in for repairs at Acer's Highpoint HQ since yesterday and no news so far. This is a huge problem for me as I am currently in the midst of my final semester in university and I need my laptop to be working at optimal conditions. This is my second time sending it in for repairs as previously I had a blown motherboard and they replaced it for me under warranty.

Please make sure the repair facility is aware of potential issues with a safety interlock switch on the mainboard which is designed to cut power to the board when the case is opened. This switch is sometimes accidentally triggered while using the laptop due to case misalignment. These two user links describe how they resolved the issue with similar laptops. Jack E/NJ
