If you need a budget laptop in a certified brand , dont think anymore and go for it.
Super design, fabulastic finishing and also value for money.
Performance is much better.
Battery backup is approximately 5 hours. Sound quality is enough for home user.
I installed windows 10 and it worked fine for me. Didnt face issues with the sound or drivers. I would suggest you folks to install windows 10, go to lenovos official website and click on support option which you will find on your left. You will then find a search box there will be an option of finding your product and serial number. Once you click on that, click on detect my product and it will automatically detect your model number. You will have to install the drivers then. Dont bother installing nvidia driver as its not recommended for this product, neither will it get installed. Once you are done installing all the drivers, just restart your laptop and everything should work fine.
Very nice design and work is around better.
You must buy it.
