Dear sir/ma'am

I have purchased this lenovo 710 series on february 25, 2018 from lenovo exclusive store jail road, new delhi. It has been a month i have formatted my laptop twice and thrice not within a span of one month.
On march 9, 2018 i raised a request regarding laptop hang issue, windows being automatically shut down after opening. The problem was resolved by lenovo customer service team there afterwards.
Now from past 2-3 days i am facing the same issue of hang and windows being drizzle some lines are coming. A pop was coming for this issue of support in blue screen and percentage span of 0%-100 % and laptop is being restarted automatically without being doing anything. So for this issue i formatted my laptop again on 18 feb, 2018 but the problem is still persisting of hang and some kind of lines are coming.
With formatting of my laptop twice and thrice times battery of laptop is not showing that much life which it was showing earlier. As i am an mba student and i am busy with all my work all the time in projects and stuff facing this kind of issue will keep a break in my work. I have trusted lenovo not only due its brand value but quality.
I contacted lenovo for this and the resolution they gave was to take video of it when it hangs. Its correct in a way i will do it when it arises but as i have my work issue and such kind of problems are coming up each and every time won't solve the issue. Dear i have spent 60000 for this and trusted lenovo in a way for it.
So, it is a request to replace the laptop as problem is being coming up each and every time and i am also not happy with customer care service as they are not able to detect what is the issue behind the problem.
I have attached my documents of the laptop.

With regards
