Introduction

The time and date, as well as other settings, are kept by the PRAM battery when your machine is off. If you feel like you're stuck in the movie Groundhog Day, replace the PRAM battery and finally turn the page of your calendar.

  1. MacBook Core Duo PRAM Battery Replacement, Battery: étape 1, image 1 de 1
    • Use a coin or spudger to rotate the battery-locking screw 90 degrees clockwise.

  2. MacBook Core Duo PRAM Battery Replacement: étape 2, image 1 de 1
    • Lift the battery out of the computer.

  3. MacBook Core Duo PRAM Battery Replacement, Memory Cover: étape 3, image 1 de 1
    • Remove the three evenly-spaced Phillips screws from along the rear wall of the battery compartment.

    • The screws are captive to the metal memory cover.

    • When replacing the battery casing, use a spudger to re-insert the foam cushioning behind the rear wall for propper battery spacing.

  4. MacBook Core Duo PRAM Battery Replacement: étape 4, image 1 de 1
    • Lift up on L-shaped memory cover, slide it to the right, and lift it out of the computer.

  5. MacBook Core Duo PRAM Battery Replacement, Upper Case: étape 5, image 1 de 1
    • Remove the following 3 screws:

    • One 11 mm Phillips #00 in the middle of the case.

    • Two 14.5 mm Phillips #00.

    • If the screws stick in the case, you can use a magnetized screwdriver to draw them out.

    • The shorter of the three screws goes in the middle.

  6. MacBook Core Duo PRAM Battery Replacement: étape 6, image 1 de 1
    • Remove the following 3 screws from the rear wall of the battery compartment:

    • Two 3 mm Phillips #00. (A1181 has three 3 mm screws and one 4 mm.)

    • One 4 mm Phillips #00 on the right side.

    • When reinstalling these screws, press gently on the lower case to line up the screw holes.

    • These screws easily strip, so be careful while taking these particular screws out.

  7. MacBook Core Duo PRAM Battery Replacement: étape 7, image 1 de 1
    • Remove the two 6 mm Phillips #00 screws from either side of the right wall of the battery compartment (not the ones closest to the battery connector).

  8. MacBook Core Duo PRAM Battery Replacement: étape 8, image 1 de 1
    • Remove the four 3 mm indicated Phillips #00 screws from the front wall of the battery compartment. When working from the left, remove the 2nd, 4th, 7th and 9th screw.

  9. MacBook Core Duo PRAM Battery Replacement: étape 9, image 1 de 1
    • Remove the following 4 screws from the back of the computer:

    • Two 7 mm shouldered Phillips on the far sides.

    • Two 10.5 mm Phillips toward the center.

    • Do not over-tighten these; you can cause the case to distort.

  10. MacBook Core Duo PRAM Battery Replacement: étape 10, image 1 de 1
    • Remove the two 5.2 mm shouldered Phillips #00 screws from the optical side of the computer.

    • It is not necessary to remove the similar screws on the other side of the computer.

  11. MacBook Core Duo PRAM Battery Replacement: étape 11, image 1 de 1
    • Starting near the display and working around to the front of the computer, pry up on the upper case. It is held with clips on the right above the optical drive. These will release with some firm lifting pressure.

    • Be careful when prying up the upper case. It's very easy to slice open a fingertip and thus provide the blood sacrifice the Mac gods sometimes require of those who insist on doing their own repairs.

    • There's a trackpad and keyboard ribbon connecting the upper case to the logic board, so don't pull the upper case off entirely just yet.

    • If you have trouble getting the clips to release, be careful that you are not prying the plastic top of the upper case away from its metal frame.

  12. MacBook Core Duo PRAM Battery Replacement: étape 12, image 1 de 1
    • While holding up the upper case (from the bottom or the top), use a spudger to pry up the orange trackpad and keyboard cable from its connector.

    • Take care to pry between the black socket and the white connector. You might have to pry on both sides for it to release properly.

    • Do not pry from the bottom or the top, but from the sides.

    • If you happen to break your upper case cable when removing the upper case, we stock the cable individually and we have a guide that makes replacing it easy.

  13. MacBook Core Duo PRAM Battery Replacement, Left I/O Frame: étape 13, image 1 de 1
    • Disconnect the MagSafe board cable from the logic board.

  14. MacBook Core Duo PRAM Battery Replacement: étape 14, image 1 de 1
    • Remove the single Phillips screw securing the left speaker to the lower case.

    • Lift the left speaker out of its housing and set it to the side.

  15. MacBook Core Duo PRAM Battery Replacement: étape 15, image 1 de 1
    • Remove the following 3 screws:

    • Two 7.5 mm Phillips from either end of the left I/O frame.

    • One 9 mm Phillips from the middle of the left I/O frame.

    • Remove the small black plastic spacer at the bottom of the left I/O frame.

  16. MacBook Core Duo PRAM Battery Replacement: étape 16, image 1 de 1
    • Lift the left I/O frame up and out of the computer. Pay attention to the thin metal EMI fingers, as they may catch as you remove the left I/O frame.

  17. MacBook Core Duo PRAM Battery Replacement, Logic Board: étape 17, image 1 de 1
    • Peel up the foil tape between the fan and the optical drive.

  18. MacBook Core Duo PRAM Battery Replacement: étape 18, image 1 de 1
    • Use a spudger to move the gray display data and black speaker cables to the right. This will reveal a silver screw securing the fan housing to the lower case.

    • Remove the following 6 screws:

    • One 3 mm Phillips on the right side of the fan.

    • One 6 mm Phillips on the left side of the fan.

    • Four 9 mm Phillips securing the heat sink to the lower case.

  23. MacBook Core Duo PRAM Battery Replacement: étape 23, image 1 de 1
    • Hold the heat sink with one hand and the fan with your other hand, and lift the heat sink and fan assembly out of the computer. The fan is attached to the heat sink only with a strip of black felt tape, so be sure to remove both parts as a unit

    • If you need to mount the heat sink back into the laptop, we have a thermal paste guide that makes replacing the thermal compound easy.

  24. MacBook Core Duo PRAM Battery Replacement: étape 24, image 1 de 1
    • Disconnect the two antenna cables from the Airport card, and the black inverter cable from the logic board.

Unfortunately not all A1181s use the replaceable battery - some use a Super-Cap. Certainly mine did, after spending 1/2 hour opening it up and flipper the case over I find no replaceable battery, rather a small device labeled “V C2800” almost under J4501 (HDD). Mine charges up to 2.8V with the AC power adapter hooked up, but quickly discharges to 0.9VDC once power is removed. I shall see if the SuperCap at Digi-Key works better…https://www.digikey.ca/product-detail/en...

Here is discussion on the SuperCap version: Is there no CMOS RAM battery on this model?
