Upgrade General Performance and Changing Battery

我的问题

After upgrade to OS El Capitain, my macbook was too slow. On the same time, the battery was down for an intensive use during 6 years.

我的修理方法

Perfect!!! The battery was fitted and recognized by system and my macbook accept 8 gb of ram. The HD was ok and i used a software called "trim enabler" to activate TRIM SUPPORT for non-Apple HD.

Great idea to supply the HD Kit: if you don't have the correct tools, it's very hard to fix a mac.
