    Need a little help. I have a 15in mid 2012 MPB. I installed a 512 SS 840 pro SSD just after 10.10 came out. My old HDD gave me around 5:30 of battery. Now with my new SSD I'm running under 3. I have "Trim Enable" program installed BUT not on. Some say to use it while others say it isn't necessary in OS 10.10. I get the felling that I'm doing something wrong or maybe I missed a step. Please let me know.

    Thanks

    Probably nothing to do with the SSD.

    They should use less power.

    Have you looked to see if there are any rogue processes running?

    Yes I have. Checked that first. I'm at a loss.

    First, use the version of TRIM enabler that support Yosemite. You can get that directly from Yosemite.

    Yosemite introduced a kext signing requirement. To enable TRIM, this has to be disabled first. TRIM Enabler will disable it for you first, restart once, then you've to enable TRIM again, and restart it a second time.

    Then TRIM will be enabled.

    The 850 Pro and 840 EVO use less power, not the 840 Pro.

    ALL SSDs should use less power than a spinning HD. They have no motor to spin up and no heads to move.

    I already did what you mentioned. There wasn't any noticeable difference in battery consumption.
