Re: AC Power adaptor wont work without usb printer...
Hey alberto, First off thanks for choosing Fixya.com. The Ac adapter itself could be bad or it could be the dc jack. And also the problem with your cpu fan could also be that the fan has gone out or the motherboard itself needs to be replaced.

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
The best thing you can try is a Static discharge.
Please remove all the external devices. Unplug the power adaptor.Remove the battery. There should be no electricity connected.
Then press the power button and keep your finger on it for about 30 seconds to release any build up electricity.
Plug in the adaptor and battery again and see if there is still a problem.
Maybe is a good idea to get a surge protector in the future.
To check if the problem is the power adaptor or the Vaio, just have a look at the charger itself and see if the green light on the adaptor itself is on?If yes, then more likely it is working fine. If no light, change the fuse in the plug and try again.
You can also try a static discharge on the Vaio. Please remove all external devices, unplug the adaptor and remove the battery. Put your finger on the power button and hold it for about 30 seconds. Then connect the power adaptor again and try to boot.
Has the ac adapter been tested with a volt meter? Sounds like it could be the ac jack or the motherboard. try removing the battery and trying it. My company charges $100.00 to replace ac jacks. If it's the board try your luck on ebay.
If the ac adapter was plugged into the laptop at the time may be bad news. Unplug AC adapter, take out the battery and hold power button for 10 seconds. Then connect AC adapter and hit power. If that doesn't work put battery back in without ac adapter and hit power button.
If neither test works bring to repair center for diagnosis. Best case AC adapter would need replacing. Worst case Motherboard fried.
