Sounds like you need a better power supply or you need to return the system.



You could get a targus 180W universal power supply pretty cheap on ebay, that should be more than enough. But that's only if your problem is due to the power supply.

i wonder really is power supply problem?

19v / 3.42A = 65w



i wonder this power can support?

Reply 6 : MSI GX640 cannot start up without battery? (plug in ac adapter)

65w is too low. Need 120W or higher I think.



If your current power supply is 65W, that is probably causing your problems.

19V/6.3A is the minimum for the MSI gamer series.

so weird

Why MSI give me 19v / 3.42A ac adapter

I use my GX640 without battery without any problems.



You should reclaim "proper" 120W AC adapter.
