I have raised complain for laptop keyboar issue before that my laptop worked previously very well without any os issue.
After the engineer did something in laptop, laptop got hanged and showing problem now.

Now my issue not resolved and vendor also badly misbehaved and they told me that they will not resolve my issue. Laptop is only 10 months and comes in under warranty.

Please resolve this issue as soon as possible as high priority basis as its impacting office work.
I launched a complain in lenovo team (Compln no-[protected]

Please solve my and issue and take some strict action against them
