Looking for laptop power jack

[Senshin]

Hello everyone.
-My laptop doesn't charge anymore. I changed power supply but it doesn't help. I opened and clean power jack. But I push the Start button, nothing happens. So I want a new power jack cable and change it by myself.
-My laptop is Dell Inspiron i17R-2895SLV (http://www.amazon.com/dp/B0081YPUTI/ref=cm_sw_r_fa_asp_1pEwD.1G141AK?fb_ref=Default%2C%40Total)
-Please help me pick a good power jack ( prefer on Amazon)
Thanks to any comment or advise in advance!

You can take your pic with the power bricks off Amazon.

We are talking about the power brick and not the female connector located inside your laptop , now, are we? On the other note, are you running an installation of Windows 10 via the free upgrade path? There have been cases known whereby some systems(laptops) wouldn't charge after a migration to Windows 10.
