Ok about the laptop I don't know if they changed the body or not but it was like totally new condition. The delivery guy was nice and waited but it came to me and battery charge was at 0% which is not expected, anyway after charging and waiting it finally started . What I got is mentioned below in detailed, I am not a professional but I will tell you everything based on my one week experience.
Pros:
1. I got like totally new condition and what I ordered , they also might have changed the thermal paste as thermals were ok.
2. From keyboard to everything was like new no scratch or dent except there was a little bent on the hard logo but it doesn't matter.
3.Ssd is probably new , ram and cpu are also in good health I checked from different apps .
4.Boots in within 5-6 seconds . Boasting cinnebench r23 score of 5879 multi and around 1000 single . I have given the photo proof .
Cons:
1. The battery is not as they mentioned above 85% . I checked lenovo vantage official app and it showed 81% health which dropped to 79% in just a week . So yes battery health is good but not as advertised as in my case .
2. They said no dead pixel but they did not check for black screen test and I found a few white pixel which is probably due to pisel size small holes , I don't know much but it is probably manufacturing defect, though they should have checked properly.
3. It's been refurbished so yes its paint won't be like new so be prepared to get your trackpad getting smooth and shiny after just one week use.
4. I got it delivered to me after 17 days of order so you have to wait a long time.
5. The rubber tap to elevate the laptop in my case was some broken or not present and so I have to elevate my laptop to let it breathe .
Overall I have uploaded some photos for reference of what I said .
Summary.
I like it but they should have checked for white pixel and actual battery health like 81% health is good but they should have mentioned that not all units come with 85% health. The only minus point for my case was the white pixel in display. I do like the laptop except for the white pixel.
I will keep holding on to the laptop as well my warranty let's see how it performs. And if you ask why I won't apply for replacement it is because the wait time is long , there's no guarantee the next laptop won't have other problem, and I don't know if they consider the small white pixel as a reasonable problem for replacement.
Thanks for reading. I hope it was helpful.
