I have been looking around on eBay but the price seems to fluctuate a little on these models, and none of my specific models have turned up yet.
Notebook: Sony Vaio VGN-SR31M (Vaio VGN-SR Series)
Processor: Intel Core 2 Duo P8600 2.4GHz
Graphics Adapter: ATI Mobility Radeon HD 3470
Display: 13.3 inch, 16:10, 1280x800 pixels, glossy: yes
The condition is still pretty good, tiny scuff here and there, battery still holds 3 hours or so (on middle setting)
