"I like the features of this laptop, with a single basic problem. The battery life is much shorter than I was told it would be. When I ordered the Y480 I was told the battery shold last about 4 hours. I have gotten a 1 to 1 1/2 hr use before I get a low battery warning. Fully charged it says it will last 2 hours, but the remaing time with use drops faster than my real time clock. Lenovo has given me 4 batteries, and they all behaved the same. I have sent the computer back to them twice at their request. Both times I was told the computer operates up to specs. I have told the techs I was led to expect 4 hrs battery life, and received no contrary information from them."
