Bought this computer six months ago and started using this only two months  back. It started having issues and will shut down with Blue screen every few minutes with  a different fault code each time. Tried resetting the computer to factory specs and it wont let me do that either. It will shutdown halfway during the reset. As its still under warranty went to Lenovo site and there it  say online warranty request is the fastest way. Created a case number and even after twelve days no response. On Lenovo site  it just says, case accepted. Tried calling them multiple times and always experiencing unusual call volumes and on hold for hours. Worst computer buy in my life and will never get anything Lenovo. Next time will buy from a retail store .
