3. When will the NIGHT code be available again? Was so tempted to buy previously, but sadly the code doesn't work anymore now haha.

So far so good! Very satisfied. I was amazed by the speaker at first haha, the sound for me is excellent.
Weight wise consider really lightweight for me.
Battery wise, currently set threshold at 70/80. But just now fully charged at 80% and I unplugged the charger, instantly dropped to 79%, wonder if it's normal? Last 4 hours 30mins just now for surfing Facebook, LYN, YouTube, FIBA Streaming. Hope it gets better for next round haha.
The material used is actually good, the soft plastic have a very nice touch feeling, smooth surface but the con is that it easily get stained with finger/palm "ink" or water droplets. Can know that the colour will start to wear off in the future. So, I might apply the carbon sticker like you did! Hahaha
However, I'm more than happy and satisfied to own this laptop!
