The warranty had been gone as the replacement by unofficial party. It is not worthy to redo CPU and RAM. It might be not working again sometime and the cost of repairment in the place out of China is too high.Ah nice big problem, but in case the repair how much could it cost? And especially if I'm under warranty but I had the screen replaced by an unofficial shop but with official components, is the warranty still valid? And above all it covers this issue that you wrote to me
