As far as I am aware, DSG Retail Ltd.'s claims that the removal of Microsoft Windows Vista Home Premium and the installation of a GNU/Linux has voided the warranty of the Laptop PC is false. Acer Inc. do not penalise their customers because of the fact that the owner may choose to install an Operating System of their choice, nor does Acer Inc. state via their warranty documentation that installing an alternative Operating System nullifies the warranty of the device whatsoever. DSG Retail Ltd.'s claims are false.
DSG Retail Ltd. are basing their claims on false information and the fact that their employees do not know how to use GNU/Linux Operating Systems. According to DSG Retail Ltd's Web site, their employees are Microsoft Certified Desktop Support Technicians, however, having visited my local premises on multiple occasions, I can state that none of their employees have worn their claimed Microsoft Certified Desktop Support Technician badge, nor are documentation or certificates displayed.
I purchased an Apple MacBook 13-inch model circa November 2006 via DSG Retail Ltd. because of the fact that I wished to use the device before purchasing it and because of the fact that there isn't an Apple Store in my location. Within one month the device reared multiple problems. I stated that its Hard Disk, Ion-Lithium Battery and CD/DVD Optical Drive were at fault. The device was sent to an Apple Certified Repair Technician and I was sent a replacement model. I was told via the Apple Certified Repair Technician himself that he had never seen an Apple MacBook with multiple problems before and that I was extremely unfortunate.
My replacement model was also at fault; it once again boasted an Ion-Lithium Battery which resulted in an operational time of 2 hours, as opposed to the stated 6 hours of operational time via Apple Inc.'s Web site. I once again returned the device to the point of sale and was told repeatedly that my claim was false. I sought legal advice via Trading Standards Ltd. and engaged in frequent conversation with DSG Retail Ltd. 4 months onwards. DSG Retail Ltd. denied on multiple occasions that my claim was verifiable, Apple Inc. also claimed that my statement was untrue. I was given a replacement Laptop PC, an Acer Aspire 9303 WSMi, as a result of my legal advice via Trading Standards Ltd. via DSG Retail Ltd. The premises employees were extremely unhelpful, indeed the Store Manager was an extremely obnoxious person whom I made a complaint against.
One week after having received my replacement Laptop PC, Apple Inc. issued a product announcement stating that Ion-Lithium Batteries within Apple MacBook and Apple MacBook Pro models were at fault; Apple Inc. had deceived myself although I wasn't concerned due to having been compensated. As a result of my atrocious treatment, I will not purchase another Apple Inc. product nor service.
