my mac book pro cord is not lightin up and I been need the battery replace it’s was turning on cutting straight back off now the cord don’t light up.and I need a fix for that also I need to find a replacement batterys.affordable good brands I also need a track pad and keyboard any Information how I do this cheap will be great!

The keyboard and trackpad issues may be caused by a swollen battery, so take care of that first, then see if those issues persist.

The MagSafe light on the charger should provide a green or orange light at least. No light indicates a problem with either the charger or the MacBook itself especially if this happens with the battery unplugged. I recommend you check that first before ordering a replacement battery which is usually only done when the battery drains too fast or doesn’t work at all when the charger is unplugged.

I can source you these parts from iFixit, but they will not be affordable in my definition (most parts are over 100 USD). I really would not go on eBay and try and order these parts from there because parts from eBay are usually a roll of the dice as to if they will work or not. iFixit rigorously tests their parts and they make sure they work with the machienes they are intended to work on before regularly sourcing vendors.
