Dell Inspiron 1545 won't turn on

I have a Dell Inspiron 1545 laptop that was purchased from Dell in February 2009.  I was using the laptop last night (with power cord plugged in), but turned it off and unplugged the power from the laptop when a severe thunder storm started approaching our area. This morning I plugged the cord back into the laptop and tried to turn it on and NOTHING happened…..no lights, no noise of fans, nada. 

Here’s what I’ve tried:

1-    I removed the battery, held the start button down for 60 seconds and tried to start with just the power cord plugged in…nothing

2-    I removed the memory modules and reseated them and tried to start…nothing

3-    I removed the hard drive and reseated and tried to start…nothing

Please advise what to do here.
