Anybody who knows how to upgrade battery firmware of Lenovo Ideapad Z400?

I have a Lenovo Ideapad Z400 that was bought in 1st-2nd week of May, 2013. I have a problem that started on May 21, 2013, my laptop battery suddenly drops from 25% to 6%. I've read some posts that it requires firmware update to work normally.. This is the site

Is there any steps needed while performing this Upgrade? Is it safe? Will it fix my problem?  By the way, I'm here in Philippines and the Ideapad Z400 was bought by my uncle somewhere in Saudi Arabia, and he delivered it to me when he got back here. I started using the laptop on May 8, 2013. Thanks..
