Hi, just bought a Spin 13 from Amazon. Powered it up and noticed it would keep turning itself off when I was moving the unit around, or when i was using it on my lap, or any moving surface. Not issues whatsoever when i'm using the unit on a table or hardtop. When the unit powers off, it would also not sometimes turn back on - the power indicator flashes light purple when i press the power button. It takes several presses, and shifting the unit around before the cbook would power back up. Tried powerflashing, battery_test etc. Should i send this back to Amazon or can a local service center (Hong Kong) fix this? Not hopeful
