*UPDATE: previous software fix didn't really fix the problem. Now going down to the hardware, the battery specifically.
After diagnosing the problem, it comes down to the battery connector to the mother board. For some reason the connector didn't attached very well to the pin. I tried to pull battery connector out, wait for about 1 minute, then plug it back in. And viola, I did not encounter the problem ever since. To be honest, never expect this hardware problem from Asus since it's a known brand for hardware. But I guess no brand is perfect.
