[Q] phone wont start even with battery full

hello, please help if you can.
i have a xperia arc s and i did not rooted it or installed any custom rom, i just have the stock rom that came on the phone.
my problem is that a couple days ago i was charging the phone with it turned off, and now everytime i try to turn on the phone, it just wont turn on.
i mean, i connect the phone to the wall charger and it says that the battery is full, but when i press the button to turn it on it just wont.
my solution has been to remove the battery and then reinserting it again, and that way i can turn on the phone, but that way is just to annoying, and i wonder if anyone has had that same kind of problem, and if has been able to find a solution and solve it, or if perhaps there is nothing to do except take it to the tecnichal assistence.
please if you can help me, this situation has been driving me completly crazy.
thank you in advance.

hello, so far as i can see, the phone doesnt turn off by it self. i am the on o turn it off

when you do turn on the phone and it works normally, does the phone shut down automatically or do you turn it off yourself?

i am affraid you wont understand my previous reply because my english is really bad so i write again,
the phone dont shut down automatically, when it turns off, its me who turn it off.
but now i notice one thing.
now after i remove and reinsert the battery again like i said, i can still turn on the phone, but now it is taking much more time than the other times i did that.
maybe all i can do is taking it to the technical assistence, but i want to be sure that there is nothing i can do, because i have friends who took it to the assistence and came back with the phone even worse than when they took it.
so please if you know something that can help me i really thank you.
