I've purchased several Amazon Renewed laptops over the years and I've noticed a huge difference in the quality based on who refurbished them. Big shout out to 2ndBazaar for really knowing their stuff and having great attention to detail.This laptop is completely indistinguishable from new. I'm a systems engineer and technician, well qualified to work on electrics. I cracked open the case of the machine and it's clean as a whistle. Even the fan has not a single speck of dust on it. It's clean inside and out, all of the components look great, no missing screws or scuffs or scrapes from working on it, etc.. I *think* the Amazon renewed requirement is for battery life to be at least 80% of it's original spec... This one is 94%... so essentially a brand new battery, since I think they often are not 100% even if you buy them brand new. They even flashed the machine with the latest firmware, something they could easily have skipped and most people would never even notice.In the interest of full disclosure, I did send back the first one they sold me. There was a problem with the display, but it was not detectable at the time. Out of the box there was a very small area of burn-in on the bottom left, only noticeable to someone like me who doesn't use Windows. Otherwise you'd never know. Whether it's related or not, the display backlight died eventually. It was accepted for return and I ordered another, which I am using right now.The only "mistakes" are good ones. Both machines have a touch display and have an additional 8 GB of memory from name brand companies.For those who want to see the exact specs, the specific model of these T490s is 20N3S5XF01. They are not listed in Lenovo's PSREF; presumably since they are late model T490s. But if you type the model into their support site, you can see all the specs, which match the actual specs of the machines I received.To get a T series Thinkpad, still officially supported by Lenovo, for this price, is really nuts. Couldn't be happier!
