With this guide, replacing your Lenovo Yoga C930-13IKB battery is quick and simple. Batteries generally deteriorate over time or have complications within their life span. This can result in low battery life and difficulty in holding charge. Check out this troubleshooting guide for more information on what might be wrong with your battery.
This guide is required for when your battery needs replacing due to quickly dying, failing to charge, or an unresponsive battery. You will remove the back cover first to access the battery, and then remove all fasteners and connections that keep the battery in place.
For your safety, discharge your battery below 25% before disassembling your device. 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.
Qué necesitas
-
-
Flip the device over so that the underside is facing up.
-
Remove the six 3.5 mm T5 Torx screws.
-
-
-
Pry off the back cover using the plastic opening tool.
-
Loosen the back cover in multiple spots using the opening tool, then remove the whole back.
The gap is so small that I wasn’t able to insert anything to pry the cover up. The suction cup tool lifted the cover off easily.
There is a very convenient spot to begin the prying process. Up by the hinge, where the metal back turns in perpendicular to the edge to get around the hinge mechanism, there is a gap between the cover and the rest of the laptop where it can be pried up easily. From there it is easy to run a tool and widen the gap all the way around.
I tried Thomas's suggestion first, and it worked like a charm: the suction cup took it right off.
Instead of pushing the cup against the laptop I "pulled it flat" and placed it against the back, so it'd just suck onto it. (Didn't want to deform the laptop cover) -

Unplug the battery from the motherboard by pinching the cables with your fingers and tugging out with force.
Pull cables toward yourself.
I was not able to grasp the wires with the battery mounted. Once I removed the battery from the case, the connector was easy to remove
I suggest waiting until you have unscrewed and un-stuck the battery from the laptop before removing the cable. It makes it much easier to get a hold of the wiring harness/plug so as to pull it out.
ALSO, if you're reading this, HIGHLY RECOMMENDED that you stop now and read all of the comments below, including the ones at the very end, after the CONCLUSION section. There's stuff that's not covered in the main steps. -
-
-
Unscrew the four 3mm screws with a Phillips screwdriver.
-
-
-
Use your fingers to pry up the clear plastic pull-tab for one of the stretch release adhesives.
-
Grasp the pull-tab and slowly pull away from the battery at a shallow angle. The adhesive strip will stretch to many times its length and slowly release from underneath the battery.
-
Repeat the procedure for the second strip on the opposite side of the battery.
-
Remove the battery with your hands.
There are two clear plastic tabs wrapped around the sides of the battery that connect to the glue strips between the battery and the backlight cover. All you have to do is peel the clear strips from the battery and pull them away. The glue under the battery pulls out like a Command Strip. No need to wreck your backlit cover and possibly the cabling underneath with tools.
Oh man I really wish I would have expanded the comments before continuing; something that took me an hour of painstaking prying could have been taken care of in 30 seconds. USE THE PULL TABS TO REMOVE THE ADHESIVE STRIPS!
Hi Brian,
Thanks for the tips! I’ll amend the guide to include this info.
I still don’t understand Step 6. Also does the new battery stick to the existing adhesive strip?
@BenBorgert - agree 100%!! I would also add that I had to give the cover a nudge towards the hinge (something seemed to click into place) to get the screw holes lined up
Did you replacement battery come with replacement adhesive strips? Mine didn't.
If you want to re-use the existing strips, you'll want to remove them carefully. As noted in the instructions, pull those clear tabs slowly and at a shallow angle. If possible, use one hand to pull and the other to hold the lengthening strip as it emerges. The goal here is to NOT LET THE STRIP SNAP OUT when it breaks free. If it does, it might snap together in a sticky, un-reusable mess.
So, take it slow, gather the excess as it emerges, and then you can stick the strips onto your new battery.
Put them in the same spot on the new one as they were on the old one (just below the top screw-bracket). And when you put the new battery in place, try not to let it stick hard to the laptop. You will need some wiggle to line up the screw holes. More on that below.
FYI, there are two very tiny metal posts in the laptop, immediately below the upper left and right screw holes. These are meant to align with some holes on the screw-brackets on the battery. So there are 3x things that hold the battery in place:
1) the screws
2) the "command strips"
3) the 2x tiny metal posts
When you put the battery in, you'll need to get both of those little posts to thread through the corresponding holes on the screw-brackets on the battery. For me, it was a matter of connecting the battery cable, gently placing the battery into the laptop, being careful NOT to press it into the sticky strip. (I pressed it in the first time and needed to take it out again, because I could not line up the 2xposts or the 4x screw holes. ) So put it in there and hover it above the screw-holes, taking care to line them up as best you can. Line up the 2x posts as well, and thread them through the little holes. Once these are threaded, check to be sure that your screw-holes are lined up and screw it in.

One little addition: After removing the bottom cover of the computer, there are two little clear plastic tapes, one on each side of the battery, that you should peel free before starting to lift the battery out. One of those tapes is shown in this photo, just to the right of the icon that resembles a figure eight: https://d3nevzfk7ii3be.cloudfront.net/ig... Those clear tapes are attached to the black plastic strips beneath the battery, that you want to try to leave in place. If you don’t peel back the clear tape tabs, they will increase the likelihood of pulling up those black plastic strips when you start to lift the battery up. My original battery was adhered quite strongly to those plastic strips, and it took a fair bit of work to “dissect” them from the battery using a straight plastic tool that had an end like a regular screwdriver. I did peel those strips up off the computer a bit, but they stuck back down after I separated them from the battery. Thanks for the instructions!
After I had finished putting my C930 back together, I noticed that the underside of the original battery had four soft black strips adhered to it, perhaps as a cushion between the battery and the components beneath. It is possible to remove those, and they could be re-applied to the new battery before installing it, but I’m not going to bother going back now to do that.
Those 2 clear strips work like Command adhesives, peal back, then pull - it stretches and detaches from the battery and the laptop. Then the battery just lifts out with ease… They are not really needed for re-installation. Probably more for protection during shipping or hard hits.
I was able to remove the 4 black, “spongy” strips from the original battery and place them on the new battery. This created a “landing” area for the adhesive strips that remained working the computer housing. All instructions were good and quite thorough. Thank you!
Thanks for the simple and straightforward guide!
Did you guys experience the situation that the new battery can’t be detected? I don’t know how to solve this issue
So, replacement went great. Battery appears to work, but the Battery indicator (on screen) doesn’t recognize the battery I guess. It doesn’t show the battery level or that its charging when plugged in. So somehow I need to get the laptop to be able to read the battery and be updating the battery level indicator. ANY HELP or experience with this?

I replaced the battery with ease. I charged it up fully and waited a couple of hours as suggested. Then, I unplugged the power adapter and let the machine run down until it went into low battery mode and turned off. I then plugged the machine back up to power adapter and let it charge fully. What I notice now is that many times the power button will be flashing so I do my typical move the mouse around or press ESC on tke keyboard to wake it up. I can use the laptop for a few minutes until the machine blacks out (like go to sleep) and the power button starts flashing again. If I do unplug the power adapter from the computer, this never happens. I am wondering if there is some sort of incompatibility with this particular battery I was sent that is having any issue with my stock charger.
Same issue as Mr. Craig Hood described.
Any solutions?

Worked great. Thanks !
Works well after 3 months. Then laptop shutdown right randomly and no longer recognized battery when plug in cable and turn back on. Similar symptoms as described by Graig Hood.
I tried updating bios, power cycles, and uninstalled/install battery driver none of these work. Plugging in the old battery works for now.
Any solution?
