    • Insert the wide edge of an opening pick into a new part of the seam between the door and the computer.

    • Pry the door up to release the clips closest to the pick.

    • Continue to slide the pick along the seam all the way around the door, prying as you go, until all the clips holding the door down have been released.

    • Pry the optical drive straight out of the laptop.

    • Remove the optical drive.

  8. SLcWw4q2L4RK23yD
    • Use the point of a spudger to pry out eleven rubber plugs covering the screws on the bottom of the laptop.

    • Some plugs have a hole or notch into which you can insert the point of a spudger to more easily pry out the plugs.

    • Remove 18 Phillips #00 screws of the following lengths:

    • Eight 8.8 mm screws

    • Seven 5.2 mm screws

    • Three screws

    Step 9: on my model the 2 lower left most red 8.8 mm screws appear to be 5.2 mm orange screws.

    • Flip the laptop right-side up.

    • Use an opening pick to pry the left and right edges of the battery cover away from the laptop enough that you can grip the cover with your fingers.

    • Lift the battery cover straight up from the laptop.

    • Do not try to completely remove the cover yet, it is still tethered by a speaker cable.

    • Open the laptop's display to a 90° angle.

    • Use a spudger to pry against one of the screw tabs on the back of the upper case assembly.

    • Make sure to pry as close as possible to the base of the tab to avoid damaging the tab.

    • Repeat this procedure with the other tab.

    • The upper case assembly is held in place by small clips around its edges. In this step, pry each tab up until you feel the nearest clips release.

    Work each side then the front.

    • Insert the flat end of a spudger in the gap between the laptop and the upper case assembly, near the display.

    • If there's not a big enough gap, repeat the previous step until you have space to insert the spudger.

    • When all the clips securing the upper case assembly have been released, lift the assembly slightly and slide it down, away from the display, about an inch.

    • Do not attempt to remove the assembly yet. It is still attached to the laptop by four cables.

    • Use the tip of a spudger to flip up the small locking flap of the keyboard backlight cable ZIF connector.

    • Be sure to pry up on the hinged flap, not the connector socket.

    • Gently pull the cable out of its socket.

    • Repeat the previous step for the keyboard, trackpad buttons, and trackpad cables held in place by ZIF connectors.

    Gently pry up onwards each of the white plastic connector just above the ribbon cable (or near the gray rib on the wider ribbon cable).

    • Pull the battery cable away from the connector in the same direction as the individual wires are running to disconnect the battery.

    • Pull evenly on the full width of the cable so that no individual wires are overly strained.

    what is the connector name for the battery?

    • Grab the black tape attached to the display cable and pull straight up to disconnect the display cable.

    Before trying to remove the display connector, gently lift tape holding speaker cable and temporarily push cable aside to allow more access to the tape holding the display cable. Then proceed to lift the display cable.

    • Slide the point of a spudger under the black antenna cable until it's snug against the connector, and pry straight up from the board to disconnect the antenna cable.

    • Follow the same procedure to disconnect the white antenna cable.

    • To reinstall these antenna cables, hold the connectors in place and gently press them straight down. The connectors “snap” into their sockets much like the metal snaps on a jacket.

    • Make sure to plug each cable into the correct socket during reassembly. The white cable should plug into the upper socket, while the black cable plugs into the lower.

    • Lift the monitor straight up and remove it.

    Please add the step to unplug both wifi antenna cables and the display connector before removing the monitor. Both just pop up.

    Sam Torres -

    Hi this comment is correct. This guide completely skips the important step of removing and replacing the wifi cables. Without this step the computer is unable to retain its wifi functions

    How to replace the lcd?

    Dima Samovol -

    I have to agree with Sam Torres on this. I reached the same spot where the screen was off, but then which wire goes to which connector. The picture is too fuzzy to be completely clear. It looks like the one further to the back (lcd screen) might be the white one and the one closer to the front of the laptop (touchpad) might be teh black one but the only way to tell is to assemble everything and then get the bad or good news.

    • Remove the two 5.7 mm Phillips #00 screws securing the battery.

    Gently rotate the battery toward the front (circuit board) to clear the back tabs. Then lift the battery out of its compartment. On replacement, roll the new batter into the compartment from front to rear. It may require some pressure for the rear side to clear the circuit board.

    • Lift the battery out of its compartment and remove it.

    • You may need to move the battery away from the motherboard to free the battery tabs.

    VERY important. The guide doesn't mention detaching the display cable or the two small cables I assume is for the display's power. Please revise because I could have broken something if I wasn't paying attention.

    Richard Joubert -

    I agree, what saved me is that I was watching someone’s video in YouTube, if not I wouldn’t have know what I broke haha

    gosorioz_89 -

    Thank you for the wonderful instructions. The only improvement would be a close up picture of one of the ribbon connectors with the hinged fastener in release position. This was a bit daunting for me until I stumbled on the release.

To reassemble your device, follow the above steps in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.

A few steps in this guide are in the wrong order. Could get confusing for and unexperienced technician. Steps 10 - 12 should be before step 6. Other than that this was a very good guide.

Aaron Bower -

Good catch! This guide was made by combining a few other guides ( we call prerequisite guides) and they were combined in the wrong order. I went ahead and fixed it. Thanks for the feedback!

Kelsea Weber -

This guide skips a very important step, without which the laptop is unable to connect to wifi networks at any reasonable range. You must reconnect the two cables on the left side of the monitor to the wifi chip. These must be in the order of white toward the monitor, black away from the monitor. I have taken pictures I would be happy to share for this step. Please contact me so I can share these pictures to remedy this oversight

ggrinste -

Still not added,! Also the removal of three tiny screws under the lip of the CD Bay is completely unnecessary and they are very very difficult to put back in.

Steve Fox -

If you don't remove the three tiny screws on the edge of the CD bay, you won't be able to remove the upper case assembly without damage on that side, so they are in fact necessary to remove.

Christopher Gilkison -

Was able to complete with little issue thanks to this guide! I did, however, run into one problem: After the battery is unscrewed, it still has small tabs to lock it into place on either side. In the pictures, it comes right out with no issue but mine was caught pretty well where the circuit board extends down. It took a nerve-wracking amount of careful prying to finally get the battery tabs clear of the silicon. Still highly doable, and this was extremely helpful!

Alex -

Very great instructions! I went step by step through them and all went well. I didn't even put a new battery in and I'm happy to report it runs perfect without it.

It gave me issues with the battery such as random shut downs, mouse lag and keyboard lag.

Matthew Whitworth -

I would love an added instruction set on how to replace the thermal compound in this laptop as well!

Matthew Whitworth -

I found this to be an excellent guide! The pictures are extremely helpful as well. I agree with Alex (10/10/2019), the battery is diabolically secured by locking tabs on both sides. It eventually comes out, but you have to shift it back and forth a bit to get it out.

Rein Allweil -

Why are screws listed in decimals of millimeters instead of the usual m2 or m5 or similar size? Is the American model actual different screws the the usual standard ones?

Jay Fensom -

Excellent tutorial. Very clear. Took me (complete novice) less than an hour to complete. Thanks

alan rowan -

Thank you so much, clear and concise instructions. Utterly magnificent.

M H -

Something as simple as a battery removal shouldn't be so complex. :P
