Ce dont vous avez besoin

As you can see, this is my own personally device that my daughter actually dropped and cracked the glass. I plan to repair it, once parts are available of course.
-
-
-
It's a pretty slick device and I'm really impressed by what it can do, especially for it's price
-
1. USB-C (Gen 2)
-
2. Power button
-
3. Volume control
-
4. Guide pins
-
5. 5-point pogo pins

You can find the entire list of specs on Lenovos website here

I expected to have to heat up the screen and deal with a display adhered in. I'm super happy to announce that is not the case here!
-
The screen assembly is held in with clips! No heat, no adhesive.
-
-
-
Once all the clips are free, the screen opens like a book the the left.
-
The lower flex cable for the display is on the upper left.
would you happen to share the original screen model number from the back of the damaged screen like:
B156xxxx, LTN173xxxx, N140xxxx, CLAA16xxxx, KP156xxxx(XY)(XY)….etc.
Does anyone know where to get the flex cable for the display? I got a replacement screen but my flex cable is broken too…
Can anyone explain to me how to reattach the flex cable to the new screen?
-
-
-
Replacing a cracked screen requires you to remove the frame on the broken screen and using two way tape to attach it to the new screen.
Be careful if replacing a screen when removing the plastic frame. I attempted to heat up the glass in order to make the adhesive easier to separate from the plastic frame and the glass screen, however, I heated it up a bit too much and it caused the plastic frame to warp. Now it has shrunk on one side and wont fit onto a new screen. Very frustrating as I can not seem to find the replacement part of just the plastic frame.
Besides the plastic frame, I also need to remove the display cable from the screen, but have no idea how that could be done... It doesn’t seem to be possible to just pull it from the white connector? Does anyone know how this can be done?
HeeHoo -
Fixed it! The cable needed to be “released” on the other side of the white connector (eg pull up with small tool or nail). I got a working LCD + touch screen from https://m.nl.aliexpress.com/item/1005002... Thanks!
How do I remove the plastic frame??
-
-
-
Just a couple Philips screws hold a bracket over the batter connector
-
Two more Philips screws hold the LCD assembly screws as well.

The Type-C Charging port, very much modular! Thank you Lenovo!

how to change the USB c (2.0) power/data port in Lenovo Chromebook Duet to USB c (3.0)
• any suggestions
• is that too complicated
• can DIYs really do it (❗)

Can't find any reference to this Chip, ITE is all I can seem to read.
-
SEC 946 B620 KMDV60010A GHGF689P RAM
-
MEDIATEK ARM MT8183V 1932-ZAMAH CTPNUN82-A the CPU
It’s an ITE IT6505(FN?), based on the kernel config: https://chromium.googlesource.com/chromi...
It’s a display port bridge chip: http://www.ite.com.tw/en/product/view?mi...
Probably a newer revision of that unit.
Also, I think the SEC chip is the EMMC. SEC is probably Samsung Electronics Corporation, and that KMD string looks like a Samsung EMMC model/serial no.
I appears to me that according to the photo shown here the first chip has following markings:
ITE
IT6505FN or possibly ITE IT8505FN
1944-BXA or possibly 1934-8XA
A18BNA
Here’s the same photo with false colors to make the text easier to see: https://imgur.com/a/iLEj41Q
I think you could get better results with red or yellow illumination while taking the photo.

MTK MT6370P 1945-ABSH ATFPX203 I believe this is a MediaTek WiFi chip of some type?
-
MEDIATEK MT6358W 1926-ANAH CCMJ2NPS OT1342 Some sort of power IC
-
QUALCOM ATHEROS ModelL QCNFA324 WiFi Chip
It appears that MTK MT6370P could be some kind of power management chip (PMIC).

Looks like some little pull tabs keep the battery in. I guess we can't have everything. But I'm happy for pull tabs and not just some adhesive I'd have to dissolve and slowly pry at. I'm going to keep this part in, since this tablet still works 100%, and I will be reassembling.
-
The model reads L16D2P31 It is a 7000mAh
-
-
-
The little pins the keyboard connects too is held by 3 little screws and looks pretty easy to replace.
-
-
-
The power and volume buttons aren't even connected to the board, they use the little surface connectors.
-
-
-
While I'm not office iFixt it, I'd say, in my experience I'd give this a 8 out of 10, for repairabily.
-
On the up side, the screen is held in with clips, meaning no adhsive or heating to open the tablet, unlike what seems every other tablet I work on these days. Lets hope repalcemt parts come in the frame, not require we move the plastic frame over to the new screen. Most of the parts are modular, including the charging port and buttons.
-
Also on the upside, all the screws are the same size, which makes for easy reassembly. The speakers are also pretty easy replace.
-
on the down side, the battery is adhered in, and some parts, like the WiFi chip are soldered on. However, looking at this from a Tablet perspective, and not a PC, that's to be expected. It does look like it might be replaceable, even if it is soldered.
-
I hope to provide updates on this device once I see what replacement parts are like, as well as cost.
Thank you my friend for this fine article. I myself own three of these devices I have two children which I bought them for. however on the second week my son who's nine dropped his and cracked the screen as well. I have been searching for replacement parts but unable to find any. Please post if you're ever find where they sell them because I would love to attempt to fix it. I noticed what mine it was a small crack on the screen however the touch sensitivity has gone away, I can still use it with the keyboard however. Right now I use it for myself to play Xbox game pass beta when I'm in my room as it has a very decent screen.
The crack on mine has got a bit worse, now I’m having touch issues as well. Once I find some, I’ll let you know.
GReat article, would be great if Lenovo would also start selling replacement keyboards!
Thanks Jeff ! Same thing here, great device but a broken screen, could be great to see it back again
It seems screens and keyboards are not available at this time. Looking forward to replacing my son’s screen. Great device and good to see this teardown. Thanks!
Having the same issue. Any screen available now? Otherwise I just threw away $250.
thank you!
i was able to pull the partial PN off the pic of the back of the screen, i believe what they’ve done is used this screen TV101WUM ( which is available on Ali Express) and used two way tape to the frame that has the clips on it. I’ve ordered one of these screens since it was only about 30 bucks, once it comes in i’ll remove the old one and try and unglue the old screen from the frame, replace the two way tape and re-install.
Have just been asked to have a crack (pardon the pun) at replacing one of these screens. Did the part arrive yet Jeff? Anyone had any joy yet with sourcing a decent replacement screen etc.?
g_caetano - How did you get on with yours?
I ordered it off that AlliExpress site, i think i got it just at the right time. You have to remove the frame off of the old screen and use some 2 way tape to attach it to the new unit. It seems to work fine, touch screen and all. I took some pictures but can’t seem to add them to this site.
It looks like the part numbers on Aliexpress are slightly different but appear to be variations of TV101WUM. I’d be fine to order one of these and try to replace it but it seems that the real part that needs to be replaced is the digitizer, not just the LCD panel (or better yet the entire frame with LCD and digitizer already installed).
Has anyone had any luck replacing the actual glass?
This just happened to us with our 10-year-old son. Is this the replacement screen and does it work?

It appears lcd is glued to the screen. I just destroyed the lcd when trying to separate the screen from the lcd. The glue is much stronger than the glue/ on the frame.
Honestly, it appars that the only spare parts one should expect to need is screen (hopefully with the plastic frame so it doesn’t need to be moved), battery and maybe charging port and power/volume buttons.
It would have been really nice if they had applied some conformal coating to guard against liquid damage directly from the factory, too.

I couldn’t quite tell for sure from the picture, but I assume that eMMC is soldered on. Any thoughts on the feasibility of a storage update?
I don’t image we could. Android and Chrome OS is all encrypted these days, so the storage and CPU are probably tied together.
Product no longer available :(
There are screen for sale here
where can one get a replacement screen? My daughter dropped hers, the screen cracked and the touchscreen is not working.
Suggestions are welcome! Thank you in advance!
Have you had any luck? Just cracked mine.
I just ordered one a couple weeks ago, coming from China, I’ll update a guide for a screen replacement once I receive one.
@jcow Where did you order your replacement screen from? I’m looking but not having much luck for an affordable part. Lenovo’s parts store lists it at $400!
could you remove the battery because I am scared about battery malfunctions. And want to see if I with no skill can do it myself,
I plan on creating a screen repair guide once I finally receive a new display. When I take it apart, I’ll add the battery removal to the steps.
The link for the replacement screens doesn’t work anymore, anyone know where to get them now?
My order with Alli got canceled. Waiting to find more available. I’ll see if I can get some more info off the screen.
I was able to order the screen with the link from AliExpress about 6 weeks ago, finally came in today. You have to remove the frame / clip from the old screen by heating it up with a hair drier to soften the glue up. It came off without breaking so i was able to use some 2 way tape to attach the new screen. Screen works including the touch screen.
how much was the screen?
roland -
anyone else have the link to the screen :)
Any luck with anyone talking to Lenovo or another way of obtaining the screen replacement?
Good news, the link on Aliexpress is working again, this is the screen i used for a successful screen replacement.
Item is described now as Used with Scratches- what was condition of yours?
roland -
I got that screen too, but it's not working: https://imgur.com/gallery/2MXo54H
I used that same link from Aliexpress and I got a screen that was too large for the device itself. Although, it plugged in and seemed to power on just fine but I couldn’t get the touch screen capability to work. However, I wasn’t able to get the original touch screen to work again either, although, that may be because I didn’t have the screen seated all the way back into the device.
I’m not sure what happened to my previous comment in case this duplicates. But I’m having the same problem — cracked screen. Has anyone found another replacement?
Doug
I have been desperate to get a replacement screen for my device. I can’t find any on Aliexpress, but I do notice that there are a few listings on eBay recently. Just search keywords like “lenovo duet display” and you should be able to find them. My device has both LCD and touch digitizer broken, so I ordered a complete screen assembly which costs ~$80 with tax included. Will see if it fits when it arrives. There are also sellers selling touch digitizer only. Hope this helps.
I found 2 EBay sellers in China with the full assembly (screen plus digitizer) for about $80 (free shipping). Both sellers have 2 items left. I ordered mine today. I confirmed the part number through the Lenovo site and it seems to match, CTX636. Good luck. I'll report back once I receive mine. I'm sure they'll sell out fast.

Seller #2:
Meh. I got my replacement in today from the link above. It was packaged well and it great condition. But, once I connected everything, it didn't work. Can't get the device to power on. Could be an operator error, since I am no huge “techie". Tried connecting the charger, although it was already fully charged when I began the repair. The tiny light near the charging port lit up blue, as usual. But nothing ever happened on the screen. It just stayed black. Took it back a part, put it back together, then tried again. No luck! Just ordered a whole new Duet from Amazon for $189. Oh well, I tried.
Anybody know where I can get The ribbon cable that goes from the computer to the lcd screen?
Does anybody know where can I buy plastic frame of Step5. I got new screen, but without the plastic frame, it cannot be held to clips of Step3 and 4.
Side note: when you hooked the screen up - did it work?
I’m thinking of using a hair drier to separate the old frame from the screen and re-use it.
I meant new frame. Old frame is damaged, in my situation old frame cannot be reused.

Finally find screen frame.
https://ko.aliexpress.com/item/100500601...
I bought screen and digitizer 2 years before, but without frame, I attached it with transparent Scotch tape.
But user ericcorbin find screen and digitizer with frame at bellow. https://www.aliexpress.us/item/325680210...

Did you ever replace the screen on this device, @jcow ?
Just repaired my Lenovo Duet using https://www.aliexpress.com/item/10050023...
Points to note:
1. The screen DOES NOT come with the plastic frame. I was lucky that mine was not broken. I used a hair dryer to gently loosen the old adhesive and remove the remnants of the old screen from the frame. I also removed the rubber gasket from around the lens for the front camera.
2. The screen does not come with adhesive - use your own.
3. The ribbon cable needs to be set all the way - the first time I did it, the backlight powered on, but not the screen. The second time, I used the flap on the ribbon cable to push it in tight and voila! it worked!
4. When the screen finally worked, the digitizer didn’t. However, once I rebooted the tablet (long hold on the power button), it worked!
I’m very satisfied - typing this from the repaired tablet!
Do USI Pens still work? And how is the Brightness? I’m thankful for your comment, as this is the only display I can find!
Joosl -
I don’t have a USI Pen to test. As for brightness - I don’t see a difference. I did compare part numbers for the screen between original and the new ones, and they were identical.
That’s nice to hear! Thanks! I’ll order mine today!
Joosl -
Has anyone been able to find the part? I can only find a replacement from China.
I can confirm a success screen replacement! I purchased from here (https://www.ebay.com/itm/184836481084) (the LCD+Digitizer) and it works perfectly.
Note: For whatever reason, after I replaced it, the charge indicator was solid red and it wouldn’t take a charge. I simply disconnected the power ribbon (yellow box in Step 6) and reconnected it. After that reset, it was back to normal!
Does anyone know where to get the black flex/ribbon cable for the display? I got a replacement screen but my flex cable is broken too…
Thank you so much! I was able to replace my screen following these instructions. Everything works perfectly!
Sadly speaking the screen is super super super super fraglie and thin glas.
I noticed that with the repair screen.
This is nothing like Gorilla Glas, and even for regular glas this is super thin.
I just wasted a repair display on this conclusion.
Havent had a device with such a crap quality … ever. Thats a newest low …
Hi. Thanks for the guide.
I used to replace a cracked digitzer (glass)
LCD was fine but touchpoints were no longer functioning.
You can now easily purchase LCD and digitiser from Aliexpress- I used GOOD LCD STORE
Note the digitiser is bonded to LCD- so purchase glass,screen & frame as one. I paid ~£60 inc p&p and tax
I found this replacement screen on the chromebookparts website. https://www.chromebookparts.com/lenovo-1... It seems to be better than most of the replacements I found on amazon. Most of the replacements on amazon do not have touch support, which is disappointing. The one in the link may be more expensive, but it seems to be a quality product from a good retailer. My sister's chromebook broke. Too much pressure was applied to the screen and now the chromebook goes crazy even though nobody is touching it. Hopefully, this screen works or I can find a digitizer for it.
You're most likely finding glass only. Unless you've got the proper equipment to separate glass from an LCD (sealed with OCA) I'd get the full assembly. Also see if you can find it "in frame" then it's a simple snap back into place instead of having to seperate the plastic frame from a potentially shattered glass.
For removing the battery, do you only have to remove the screen first, how easy is it to do that? My screen is fine but I want to replace the battery since it's starting to die within three or so hours.
Yes you do have to removed the screen first, however it's held in with clips and pretty easy to remove. The battery however is held in with adhesive, but they are pull tabs, which is a plus!
Did it work? Was this the right part? https://www.aliexpress.us/item/325680210... You can click the second box under "color" and get one "with frame." Does this include the screen and digitizer?
Just replaced my screen using your guide. Thanks.
I’m in a similar spot. My son dropped his. When do you think parts will be available? Any clue? I’ve spoken with local distributors and Lenovo. I’ve not found a lot of help.

Hi guys
my dog accidentally grabbed my chrome book and cracked the top right part
display intact but minor ghosting issues and that top corner touch is unresponsive
ive found a temporary solution
we can disable touchscreen google it and use search + shift + t
this is toggle on or off as per requirement
and use as a mini laptop until we get a screen replacement glass.

My niece stepped on my daughter's Duet Chromebook. Went to a repair store and they said the only thing I could do is just buy a new one. Nope, I am waiting on screen replacements to come available. Meanwhile, she can still use it with a mouse or the pad on the keyboard, but I'd like to get it working with touchscreen again.
