[This review was collected as part of a promotion.] I ordered a ThinkStation P620 in order to do engineering/CAD as part of my job as a consultant. When I received the machine, I powered it up and attempted to complete the initial setup, and so forth During the setup procedure, the PC would repeatedly power off and restart (Black Screen). I entered a service request, and a technician came to my house and replaced the system board. Afterward, the PC would not complete POST and would remain in a non-functional state. I have requested a full replacement. To date (4 days) ago the shipping status has not been updated (although I was told on the phone it would arrive this coming Wednesday. I am very discouraged with having been sold an expensive non-functional PC. If any sort of pre-ship burn-in (or simple power-on test) had been performed the failure would have been caught and I would not have lost over a week of billable time (easily more than the cost of the machine), had to explain to my clients my I can't complete their work, and so forth. It has cost me time, money, and reputation. I am hoping I will receive what I paid for this coming Wednesday. It would go a long way if 1. Lenovo would commit to a delivery time, 2. make some compensation for their mistake, for example, upgrading the memory, or processor.
