Sony vaio r505jl docking station

If you don't give us the model reference of your VAIO, we can't help you...

Yes it should if you are running Windows XP, Vista, 7 or 8. You just connect to the unit using a spare USB port on your laptop and a plug-plug USB cable. It has it's own power so you'll need a mains socket. This means you can unplug your laptop and leave any devices charging on the docking station USBs. Your laptop should auto-instal the station. I believe there is a table/support available which combines with this unit. There a varying prices for this unit so look around.
Good Luck

You should be able to hook up the laptop using a common audio cable, one end hooking up to the audio-in port in the docking station, and the other end hooking up to the audio port in the laptop.

The problem is definitely not with your docking station. Its the ethernet controller that is faulty. Possible reasons can be incorrect driver or device failure(not very unusual).
You said that you "have tried to install drivers from Marvell but no luck". This most likely indicates the device(ethernet controller) failure. Anyways try to download the drivers from the link below and give it one more shot.

If it still doesn't work a new ethernet controller card should do the trick. Considering the fact that you can get a good one from brands like D-link, Realtek etc., for about 25$ it shouldn't be much of a problem.

Hope this helps,
Sai.

It is hardly possible that anyone will even try to repair it. And believe it or not, it is cheaper to buy a new one then to repair the old one

Use the USB Hub...to have additional USB port..

It is possible that the motheboard has gone bad.  The power brick could also have developed a short in the cable.  I would first see if you could use a different porwe cable and try that.  If that doesn't work, then i would suggest changing the motherboard if possible.

It could be the connector on the bottom of your laptop that's creating the problem. Does any other ports work on the docking station when docked?
