My VAIO PCG-505FX has the same problem. Cannot power on even with battery or power cord on. Someone told me this is the battery problem and when you try to power up, it will eventially draw-out the CMOS battery and cannot open forever.

However, I try to put the battery in the refrigerator (the freezing box), and wait about 10 mins, take it back and restart, my deadly VAIO can reborn again. You may try this (but take your only risk).

Anyone if also successfully recover your VAIO like this, let me know

The battery may be inside an enclosure, or it's wrapping may be a different color from the replacement, or the original battery may be a different shape.
Try to find the connector and wires - they must be the same, same no. of wires.
In most cases, replacement of the CMOS battery is an easy task. It is simply a matter of locating the battery on the computer's motherboard, removing it and plugging in a new one. As a rule, internal batteries should be replaced by the same type of battery which was originally used in the machine or according to the manufacturers specifications.

It may be (this is not likely)the original battery is soldered to the board, you have to enable/disable a jumper to disable it, and find the pins the replacement battery plugs into (usually near the original) - there might be a label or a + near the pins.

Personally, I would charge ahead and figure it out - but that's me.
If you are timid about doing this, or have bad experiences when you try to fix things, have someone who services laptops do it.

Here is a link to a replacement battery. It's long, so if it doesn't work, copy and paste it into your address bar.
