Hello I bought a laptop in September 2015 from pcspecialist £1200. Paid the deposit of about 100+ with credit card and chose to pay off the finance with up to12 months 0%apr if settled before 12 months. which I paid early in May. After about 3 weeks of having the laptop it developed a warbling sound from one of the speakers which I reported to pcspecialist, they said for me to return it, but as I was working away I was unable to as I needed it. The opportunity came 2 weeks ago were I could and have returned it and they have said that its a design fault, that they can do nothing about it. Email from them below. "This is a brief status update for your RMA ). Our aim is to keep you informed as much as possible throughout the RMA process. New notes have been added to your RMA as follows: "Hi I have been testing the system running various tests to try and stop the whine from the sub speaker. I have updated the BIOS in hopes that this would regulate the voltages more efficiently but unfortunately this has not worked. I have also tried to under volt the CPU in order to reduce the whine but again this has not worked. After testing of various components and looking into how the motherboard and components are seated in the chassis it has shown that the sound is being caused by the chassis its self. Unfortunately this is the same across all laptops in this range and I have experienced a similar issue with an older laptop that would produce the same problem but when connecting speakers to the headphone jack. There is no way that I can remedy this as it is down to how the chassis are manufactured. We have been in contact with the manufacturer and they tell us that this noise is considered to be within manufacturing tolerances. I am sorry that there is nothing I can do to prevent this. The only means to avoid this would be to have some music or video to be playing with volume. Please let me know your thoughts on the matter." So it looks like the laptop is not fit for purpose as its a design fault? The noise isn't loud but loud enough to annoy you when sat working on it. Where do I stand I either getting the UN-fixable fixed or upgrade to a different model or even a refund (which I don't really want) I just find it hard to believe that every laptop "octane" warbles at the user Any help would be appreciated
