Acer ONE 150 does not stays ON

Hi everybody, my acer aspire one does not stays ON, it runs for about 15 to 20 seconds and then it turns complitely OFF, it was working the night before my flight from Miami FL to Chicago and the first time I tryed to turn it ON after the security screening it just does not stays ON it boots alright, the longest it runned was up to the point I had typed the second character of my Password for windows XP, does any one have any Idea or knows how to deal with that problem?

I did check my battery charger, it is putting out 19.31 Vdc, I left it charging overnight and I did tryed to turn it ON with and with out the battery as well with and with out the battery charger same thing works for about 15 to 20 seconds and it shuts down.

 

I am happy that after my post I did spend more time looking for and reading ather posted topics, because I found one post with a replay form "Soupdragon" who sugested to tap and shouk the fan area of my Acer ONE and it did solved the problem it seams that when in flight and by having my laptop case in front of my feet I must have kicked and (that is a negative for Acer) the Fan was moved away from it's normal mount.

Soupdragon if read that thank you and I added you as my friend, Achilles
