It has battry life of exactly 5 hours, beyond that it doesn’t last. I I came to conclusion after my several test. Lenovo website advertises the battery life as upto 8.7 hours. This is very bad. Atleast 6 hours would have made sense.
In terms of performance:
My system is an 8GB core i5 1.9GHZ CPU speed. It works absolutely fine with no problem. Very fast in opening applications and running heavy softwares which occupy 5GB-8GB of space and are specifically electrical engineering simulation softwares.
A little problem which I face I get it started, blue screen appears a few times. The screen stop at the starting up page for hours. After reset and it work fine.if it would have more skinny that would add more star to its appearance.
