I have purchased Dell Inspiron 14R laptop 3 months ago from the online store of Dell, but m not happy with the performance of the system, its having number of issue which makes it hard for me to use regularly

I am facing following issues in my laptop:-

Battery back up is very low, maximum of one and half hour
Sound is not good, bass is too high i have seen many cases for this in dell... i think speakers are gone...
Shut down screen button is not working
System is getting black out as and when i pick my finger from touchpad
Color is getting fade from the touch pad just in 3 months as like i have scratched it from there.

Please suggest me some solution to replace the laptop and get me some better quality laptop... i am ready to bear the loss if any.. i have spent 43k on this. please change my laptop.
