Track down a number of hardware problems using the MacBook Pro 13" Unibody Troubleshooting Guide.
There are a number of components in the MacBook Pro 13" Unibody Early 2011 that can be cost effectively upgraded.
- Memory: The MacBook Pro 13" Unibody Early 2011 comes with 4 GB RAM standard, and accepts a maximum of 16 GB. If your MacBook Pro is still running with only the stock RAM, upgrading will provide a dramatic performance boost. You can upgrade to any combination of two 4 GB or 8 GB modules for 8, 12, or 16 GB of total RAM.
- Hard Drive: 320 or 500 GB hard drives came standard with the Early 2011 MacBook Pro 13" Unibody. You can easily upgrade the drive to 750 GB, 1 TB or a lightning-fast solid state drive. For a full list of available upgrade options, check out our selection of MacBook Pro 13" Unibody Early 2011 hard drives. Be advised, at the moment you need to use a piece of software to enable trim, called Trim Enabler—this involves some risk.
- Additional Storage: With the growing popularity of flash memory and cloud storage, you may find yourself rarely using the SuperDrive in your MacBook Pro. The optical drive can easily be replaced with a second hard drive or SSD using an optical bay hard drive enclosure. When installed, your additional hard drive will mount on your desktop just like an external hard drive.
- Battery: The battery is certainly replaceable, even though Apple doesn't consider it to be "user serviceable." See the Battery Replacement guide above for complete replacement information.
