HP 2230s laptop wont power on

Hello,

I have a HP 2230s laptop which will no longer power on, either with or without using the battery or main power source, or both. Nothing works, it's completely dead even though it worked just fine until last time I shut it down. When battery is in, the power light blink three times indicating low battery. Except for that, nothing happens.

This has happened to me once before and it just went away after a couple of hours. Now it's been this way for over a day. Extremely grateful for any help!!

This has happened on both Windows Vista and Win 7 (64 bit).
