Sony Vaio laptop - i5, 4GB, Blu-ray RW ?

PLEASE NOTE: I will remove the ad when the laptop is sold, so if you see this advert then it is still for sale :) thanks. EDIT: Whilst reformatting the laptop just now, I have noticed that the row of F keys (F1, F2 etc) do not toggle the brightness/volume as expected and F1 seems to get stuck on occasion, keeps fetching up the help page until pressed a few times. The brightness/volume can still be changed using the normal software process, just the keyboard short-cuts for this functionality seems to not be working properly?! It is something I never used myself so have not noticed until now. I have therefore reduced the price to 350 which is now less than half the price I paid for it May last year. Top spec Sony Vaio laptop purchased May last year for just over 700, excellent condition (bar the bizzare afore mentioned F key issue). Comes in original box with instructions, charger and everything else it came with; even the cable ties :) Glossy black Windows 7 home edition Intel i5 2.66GHz processor 4 GB RAM 39.4cm LCD screen, 1366x767 Integrated webcam ATI Mobility Radeon HD5470 graphics 512MB Office 2010 starter Wifi and bluetooth SD and MS card slot Blu-ray RW Looking for 350, item can be collected/delivered (within reasonable distance) or posted though be aware the postage will be about 25 including insurance.
