You would probably be better off buying a new notebook. Not sure how tecnologically advanced you are but it seems you already did the troubleshooting yourself. But i am very interested in the a/c adaptor output. If the led on the adaptor is green that just means that it is getting power from the wall.
What did you mean by fluid leaking out?
It could be the mobo (motherboard) or it could be the connections from the power to the machine. If you want to put a new mobo in I have to warn you that taking apart a laptop is VERY difficult and I do not recommend this unless you are a PRO. This is just about the only link i can find to buy a new board. If you google your laptop model you will find out you definately are not alone with this problem
Please don't forget to rate my response and let me know if there is anything else I can help you with.

Move the power jack around while plugged in, does the blinking on the battery stop when you hold it in certain positions? If so, your dc-jack needs to be soldered, but i probably was loose already before you started using it. It could be a broken motherboard issue as well. You can try to open the laptop and check the dc connection. There is a Laptop Repair Guide that shows you how to take apart a laptop, the sony may be made in a similar way. Sony Repair NYC

I own a Acer 1800, I have fixed it many time.
Each time it beep and flash power button it mean the charger adapter is not giving a constant 19V voltage.
I also saw that you unplug the charger and test and there you have 19V. The answer is, sometime when there is no charge the adapter can provide 19V, but this laptop need 7.9 amp to work so when a charge is apply to the charger voltage drop and shutdown.
Most of the time I found myself opening the charger and sodering back capacitor. whatch for what we call a cold weld.
It is a place where arround a leg of an electronic part the soldering is gone or has a small round shape crack. those are cold joint.
if you don't feel like fixing your adapter, then whatch on ebay there is some to be sold. I found them to be cheap.
Whatch for the correct voltage and amperage otherwise your computer won't work correctly.

First, you need to make sure your power adapter is providing enough
power to both run the laptop & charge the battery. A very good way
to do this is to compare your laptop voltage & ampere requirements
(written on a sticker on the bottom of the laptop) with the voltage
& ampere ratings of the power adapter. Voltages should be the same,
or the power adapter's voltage about up to 0.5 volts more than the
laptop's voltage rating. Amperage of the power adapter should be at
least equal to or greater than the laptop's rating. It should never be
less than the laptop's rating, or else the power adapter will be
providing insufficient amperes to charge the battery. Of course, the
power adapter's nominal amperage might be ok, but it degraded on usage.
You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.
