Error Code 2000-0151, HDD, 3E Smart Predictive Failure

Hello,

Today morning when I turn on my laptop, I got an error from Intel Rapid Storage that the laptop may fail and I must take a bacjup. I tried running Boot time Diagnostic and it gave me following message:

Error Code 2000-0151

Validation 116622

Msg: Hard Drive 0 - S/N W0VAY77L, Incorrect status = 3E 

SMART Predictive Failure.

Please guide me if HD need to be replaced. My laptop is under warranty.
