Ideapad z400 battery and window 8.1 problem

I have a z400 laptop and are facing battery problem. A fully charged battery only last for 5-10minutes before it auto shut down my computer. 

 

For window 8.1 issue, my laptop brightness cannot be adjust after upgraded as well as the bluetooth functionality. I am unable to connect to my wireless headset via bluetooth. 

 

May i know if i send my laptop for warranty service, do i have to make any payment for the above issue? 

 

Thank you for your attention

 

Jeff
