hi , (i live in uk) i recently purchased two sony ex office laptops product name - svs1313p9eb model-SVS131G22M they are 13.3 i5 cpu windows 8 pro ,,,19.5v 3.3a i had intentions to fix them up for my 2 sons , problem is i need bottom hd/battery cover and sata hard drive cable , i found a few covers on ebay for model VPCSB but they are slightly different , i am starting to get worried i will never find replacments , as for the laptops themselves i can find very little information , they are not even listed on sony webdite which makes it more confusing to try and find parts , thankyou for reading and hopefully i may get some good news
