Hi i have bought the lenovo laptop g50-70 model name 20351 about a year ago and it work well for a year and after that its vga graphic card got corrupted. When i take it take back to the buyer they says they can't do anything because the warranty is over so, can you kindly tell me what to do now or your laptop only work until the warranty is valid.
