Vaio AR21S and Vaio AR71S or US Version Vaio AR770 Motherboard number

[estezijem]

Hi, can somebody tell me, what is the exact number of the motherboard in the Vaio AR21S or in the US version AR770? I'm looking for a motherboard with Geforce 7600 GT or with Geforce 8600 GT. Thanks. Stefan

Hi Stefan and welcome to the forum.

Unfortunately I suspect that a new motherboard will cost you as much, if not more than a replacement notebook - possibly up to $2000.

Check out Nexttronics which, as far as I am aware, is the only supply only source for Sony parts.

Hello and thanks for welcome! The motherboard in my AR21S is defect. The Geforce Go 7600GT doesn't work properly anymore. I'm looking for a replacement of the motherboard, but I need to know the exact number of it in order to look for it on Ebay, etc. I was thinking about the possibility to replace the motherboard with another one from a newer AR series, which has Geforce 8600GT 512MB, but I would be happy with the only graphics chip or the original AR21S motherboard at disposal. Any ideas?

Hello

Do not bother replacing the motherboard. Sell what is still working and throw the rest in the garbage. If the idea of buying another Sony Vaio appears in your head then try to ignore it. Never buy another one of this companies computers again.
Save your money and buy something else.

Reasons why:
1. Sony's overseas technical support is utterly rubbish
2. Between 18 months to 2 years the video chip will explode. If your lucky. Does not matter
which manufacturer you choose, Nvidia or Ati, both will die after 2 years.
3. Build quality on the latest machines is terrible, doors break, paint rubs off and paint
starts chipping off.
4. No 3 year warranty

I have just had my VGN-AR21S video chip go wrong. This is the 4th Vaio Notebook to suffer from the same problem. I cannot afford to keep buying Vaio computers.
I even had Sony in Japan service the thing 6 months ago after both internal hard drives fail.

BUY SOMETHING ELSE AND SAVE YOUR MONEY.

We used to be a 'wall to wall' Sony company: laptops, monitors, TVs, pro-video cameras & video HDDs, NLE and other software.

Then we bought an AR21S laptop and two weeks after the warranty ran out the motherboard went kaput. The response from Sony was abysmal, their contention being that there was no established manufacturing defect that rendered the item as not fit for purpose.

Sony's suggestion was that we paid £100s to repair an item that clearly had a manufacturing defect and to use replacement parts that... wait for it... couldn't be guaranteed not have the same problem.

That was enough. Not a single penny has been spent on Sony products since and nor will there be until someone from Sony contacts us with a new laptop and an apology.
