ACER 4520 can not on

[Guest]

Hello,
My Acer 4520 can not on. I had tried all treatment to solve the problem until I frustated. yesterday, my laptop can power on and normal. But today can not on again. Why?

Does it work with just the battery in or with just the AC plugged in or both? Is the battery charging? I ask because it helps to narrow the issue down to perhaps a bad AC adapter, battery, or power jack.

It can work with both of battery in and just the AC plugged in. Thanks buwish. I wait for your help.
