My computer is 2.5 years old (just out of warranty), expensive top of the range, and the RAM is faulty so my computer randomly shuts down several times per day. Built in RAM that can't be changed or fixed - I must throw away the computer that cost me 800€. Lenovo doesn't have customer care beyond a useless chatbot. They won't respond to my questions and definitely won't accept any responsibility for their faulty equioment! I will NEVER again buy a Lenovo and I certainly recommend you not to do it!
