Einleitung

Use this guide to replace a worn-out or dead battery on a Microsoft Surface Laptop 3 (13.5").

Note: Some photos in this guide are from the 15” model and may contain slight visual discrepancies, but they won't affect the guide procedure.

For your safety, discharge the battery below 25% before disassembling your laptop. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

If your battery is swollen, take appropriate precautions.

You'll need replacement adhesive for the battery in order to complete this repair. Strong double-sided tape like Tesa 61395 is recommended.

Surface Laptop 3 13.5" Battery

Schritt 1

Flip the laptop over and place it on your work surface, feet facing up.

Schritt 2

The feet on the bottom of the laptop are meant to be removed with the pointed end of a spudger.
Each foot has a hidden indent that will simplify removal.
To make sure the spudger is in the indent, insert it at the nearest long edge, pushing parallel to the short edges of the laptop, as shown.
Note that the two feet near the rear (screen) edge are different than the two front feet.

Schritt 3

Insert the pointed end of a spudger underneath one of the two rear feet, at its rear edge.
Push the spudger underneath the foot and pry up to release it.
The two rear feet are secured with some light adhesive.
Repeat to remove the second rear foot.

Schritt 4

Insert the pointed end of a spudger underneath one of the two front feet, at its front edge.
Push the spudger underneath the foot and pry up to release it.
The two front feet are secured with plastic clips as well as light adhesive.
Repeat to remove the second front foot.

Schritt 5

During reassembly:
Note that the front and rear feet are different.
Note that the front feet are directional and only clip in one way.

Schritt 6

In place of reusing old, worn out feet on your device, 8 mm rubber furniture pads can be a good substitute.
Peel a pad away from its backing, align it over a foot cavity, and press to secure.

Schritt 7

Use a T5 Torx driver to remove the four 3 mm screws in the foot cavities securing the upper case to the device.
Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your laptop.
During reassembly, don't over-tighten these screws—they strip easily.

Schritt 8

Flip the device over.
Open the display as far as it will go.

Schritt 9

The upper case is secured in place by magnets.
Grip the top edge of upper case above the keyboard and lift straight up to release it.
Don't try to completely remove the upper case just yet, as it's still connected to the rest of the laptop.
Lift the front edge of the upper case up and away from the laptop, taking care to not strain the keyboard and touchpad ribbon cable underneath.
During reassembly, lower the upper case onto the lower case until the magnets snap into place and it lays flat.
Check that the upper case sits flush around the entire perimeter. Any gaps between the upper and lower case near the display could cause damage to the display as it closes.

Schritt 10

The keyboard and touchpad ribbon cable is secured in place by a magnet connector.
On some models, this connector is surrounded by black tape.
Insert the flat end of a spudger underneath one edge of the ribbon cable connector, and pry up to release it.
Remove the ribbon cable from the motherboard.

Schritt 11

Remove the upper case.
Set the upper case onto a clean surface, keyboard-side down.
Ensure the ribbon cable lays flat, and isn't twisted or stressed.

Excellent instructions. Just replaced my upper case. Also thanks for the tip for replacement rubber feet.

Schritt 12

Use a T5 Torx driver to remove the 2.7 mm screw securing the SSD.
Removing the SSD also functions as a battery disconnect and should be performed before all major repairs.

Schritt 13

With the SSD screw removed, the SSD will pop up at a shallow angle.
Grip the end of the SSD and pull it away from its board connector to remove it.
During reassembly, insert the SSD at a shallow angle into its board connector, and secure it back into its horizontal position with the SSD screw.

Schritt 14

Use a pair of tweezers to remove the two pieces of black tape covering the bottom left and bottom right corners of the motherboard.
During reassembly, reapply the tape if it's sticky enough to be reused.

Schritt 15

Insert the tip of one arm of a sharp pair of tweezers into one of the holes near the top left corner of the heatsink shield.
Pull upwards to release the top left corner of the shield.
This may require a considerable amount of force, but try not to deform the shield too much—you'll need to reinstall it during reassembly.

Schritt 16

Repeat the previous step's procedure to release the top right corner of the heatsink shield.

Schritt 17

Continue along the heatsink's top edge, inserting a tweezer arm into the shield holes and prying upwards on each one as you go.

Schritt 18

Once the top edge is loose, use your fingers to grip the top of the shield and pull it up and away from the heatsink to release the remainder of the shield.
Try not to deform the shield too much—you'll need to reinstall it during reassembly.
Completely remove the heatsink shield.

Schritt 19

Use the pointed end of a spudger to flip up the locking flap on the fan cable's ZIF connector.
Use a pair of tweezers to pull the fan cable straight out of the connector.

Schritt 20

Use a T3 Torx driver to remove the nine screws securing the heatsink:
One 2.5 mm screw
Three 2.0 mm screws
One 3.0 mm screw
Two 4.1 mm screws
Two 3.4 mm screws

Schritt 21

During reassembly:
Align the heatsink with the centering peg on the motherboard.
Tighten the four CPU tension screws in an "X" pattern.

Schritt 22

Use the tip of your finger to lift the far right edge of the heatsink up and off of the small alignment peg near the right side of the fan on the lower case.
Once the heatsink has cleared the peg, lightly pull the right edge towards the front of the device.

Schritt 23

Remove the heatsink.
If the heatsink feels stuck to the CPU, gently wiggle it side-to-side to separate it from the thermal paste holding it down.
Don't pull on the heatsink too hard; the heat pipes are susceptible to creasing.

Schritt 24

Before reinstalling the heatsink, follow this guide to clean the heatsink and CPU and reapply thermal paste.

Schritt 25

Some motherboard screws are located under two of the metal shields, both of which need to be removed.
Use an opening tool to pry up an edge of the metal shield covering the right side of the motherboard.
Try not to deform the shield too much—you will need to reinstall it during reassembly.
Work your way around the perimeter of the shield, prying up intermittently, until you can remove it completely.
Remove the shield.

Schritt 26

Repeat the previous step to remove the second shield from the left side of the motherboard, closest to the CPU.

Schritt 27

Use the pointed end of a spudger to lift and disconnect the right speaker wire from its connector on the motherboard.

Schritt 28

Use an opening tool to flip open the gold locking arm on the Surface Connect port's motherboard connector.

Schritt 29

Grip the Surface Connect port cable and pull it away from its connector to remove it.

Schritt 30

Use the pointed end of a spudger to lift and disconnect the left speaker wire from its connector on the motherboard.

Schritt 31

Use an opening tool to pry up the black shield covering the right bank of display connectors.
Try not to deform the shield too much—you will need to reinstall it during reassembly.
Repeat at different points around the shield until it becomes loose.
Remove the shield.

Schritt 32

Repeat the previous step to remove the remaining shield from the left bank of display connectors.

Schritt 33

Use the flat end of a spudger to pry the first display cable up and out of its socket on the motherboard to disconnect it.

Schritt 34

Disconnect the three remaining display connectors.

Schritt 35

During reassembly, use the flat end of a spudger to gently push the display cables back into their cavity in the lower case.

Schritt 36

Use a pair of tweezers to grip the antenna cable close to its base.
Pull straight up to disconnect the cable.

Schritt 37

Use a T3 Torx driver to remove the two 3 mm screws securing the motherboard bracket.

Schritt 38

Use a pair of tweezers to remove the motherboard bracket.

Schritt 39

Use a T3 Torx driver to remove the six 2 mm screws securing the motherboard.

Schritt 40

Use your fingers to lift and remove the motherboard.
If the motherboard feels stuck, slide the motherboard to the right so the I/O ports clear their cutouts on the chassis.
Ensure the two screwpost braces underneath the motherboard don't get lost during removal.

The right side moves but the left side seems really stuck

Schritt 41

When you reinstall the motherboard, verify that no cables get trapped under the board as you lower it into place. Check each of the five locations carefully:
Four display cables
Antenna cable
Left speaker cable
Surface Connect cable
Right speaker cable

Schritt 42

Heat an iOpener and lay it on top of the battery contact cable for about a minute, in order to soften the adhesive securing it to the case.
If you don't have an iOpener, use a hair dryer to warm up the cable instead.

Schritt 43

Slide an opening pick underneath the battery contact cable to separate it from the case.
If the adhesive is stubborn, don't force the pick. Lightly reheat the cable and try again.
During reassembly, note that the contact cable is centered in place with both a screwpost and an alignment peg.

Schritt 44

Use a T3 Torx driver to remove the six 2.7 mm screws securing the battery to the case.

Schritt 45

Apply adhesive remover or high-concentration (90% or higher) isopropyl alcohol to the top edges of all three battery cell groups.
If you are using adhesive remover, follow these preparation steps first.
Wait 2–3 minutes for the adhesive remover to penetrate and soften the adhesive before you proceed to the next step.

Schritt 46

Take care not to puncture or bend the battery with your tools—a punctured or bent battery may leak dangerous chemicals or cause a thermal event.
Slide a plastic card underneath the far left battery cell group to slice through the adhesive holding it to the case.
If you encounter significant resistance at any point during this procedure, pause and apply more adhesive remover. Wait for it to soak into the adhesive, and try again.
Wiggle the card from side to side as you insert it under the battery cells to fully separate all adhesive holding them in place.
Leave the plastic card temporarily underneath the cell to prevent it from re-adhering while you continue.

Schritt 47

Slide a second plastic card underneath the middle battery cell group to slice through the adhesive holding it to the case.
Wiggle the card from side to side as you insert it under the battery cells to fully separate all adhesive holding them in place.

Schritt 48

Slide the card out from under the middle cell group.
Leave the card that's underneath the left group in place for now.
Slide the plastic card underneath the far right battery cell group to slice through the adhesive holding it to the case.
Wiggle the card from side to side as you insert it under the battery cells to fully separate all adhesive holding them in place.
Leave the plastic card temporarily underneath the right cell group to prevent it from re-adhering while you continue.

Schritt 49

Use both plastic cards to lift the entire battery assembly up and away from the case.
If the battery still feels adhered to the case, reapply adhesive remover and use the plastic cards in problem areas to make sure all three cell groups are fully separated from the case.
Remove the battery.
During reassembly, double-check the fit and alignment of your new battery before sticking it down.
If your battery came with adhesive pre-installed on the bottom, flip it over and carefully peel away the liner to expose the adhesive. If your battery did not come with adhesive, apply a thin double-sided adhesive tape such as Tesa 61395 to keep your battery in place.
Carefully position the battery and set it into place. Press and hold each cell group firmly for 5–10 seconds to secure it to the lower case.

Thank you for showing how difficult it is to repair these devices. If it were my personal device, I’d give the task a shot. Instead, this is for work and I have to go with an option other than Surface as I have to be able to repair devices when the battery or other components fail instead of having to replace the entire device.
