"My Surface Pro 7 died completely overnight. As a doctor, I had patient records and medical software I needed urgently. Microsoft wanted almost RM 3,000 to replace the entire logic board - that's more than buying a new Surface! Ahmad at Techfix diagnosed it as a power chip failure and said he could replace just that component. I was skeptical but desperate. He used a microscope to replace this tiny chip and my Surface came back to life! Everything works perfectly, all my data is safe, and I only paid RM 749. He saved me over RM 2,000 and saved my device. This is true expert-level repair work. Highly recommend for anyone told they need board replacement!"
