So, I successfully changed the battery, had it working for about a week, and now my battery is again dead and wont charge.

Checked solder points, all good. is there a way to check if the battery charger is charging using a voltmeter?

Thanks.

Great directions. I would add, the terminal leads on the battery ifixit sells need to be trimmed to fit through the circuit board. And mine was not marked clearly + or - ends. Went based upon end cap style. Works great and saves me $100+!!!

Overall, a great guide. replacing the HDD was more difficult than i expected as the holes are hard to line up on the back surface. Turning the computer bottom side down helped. This also allowed better fitment of the antenna surface. Its worth noting that not all HDDs have a screw hole located on the left hand side, so mine is secured by only one screw.

I took the opportunity to pull the heatsink and replace the paste with Arctic Silver paste. So far my temp gauge (palm of my hand:)) says its running cooler.

Great work ifixit!
