Sky News in the UK have exposed several laptop repair shops including some big names like Micro Anvika and PC World. During the investigation, researchers unplugged a RAM stick from a laptop to see if the shops would simply diagnose the fault or charge extra for work and components. Only one shop was genuinely honest, Pix 4 in Shepherds Bush. The rest, including Micro Anvika and PC World, charged huge amounts for work that was not required, including replacing the laptop motherboard.
