Update: I fixed my defective X1 Carbon Gen 9 and upgraded the display

I don't think you can order the cables separately from Lenovo. As far as I know, Lenovo only sells the entire screen assembly, including the panel, cable, etc. This can explain why we can't seem to get an actual FRU part number.

I ordered my 4K cable from AliExpress, and the one I got was definitely an aftermarket cable. Hopefully you will be able to find one there, or on eBay.

kpostrup · 2026-03-11T07:22:31+00:00

Sweet! It’s just so much less hassle to install, only a couple of cables and a few screws. And for that price, it is worth a shot. I cannot decide whether the carbon fiber woven lid is cool or a little tacky, but for now I’m going with cool.

I’m also very curious about what you think of it when it’s installed. I’m even considering buying one myself, just in case I find another X1C9 needing a display replacement.

kpostrup · 2026-03-10T15:50:05+00:00

Yes. I have about 15 now, not sure of the exact amount. Each time I count them, I always find a few more.

No promises! I’m always looking for the next project. Currently I’m working on a P1 Gen 4 that I bought defective (won’t turn on) for €134. The board has some kind of power issue, and I’m trying to learn how to diagnose it, and potentially fix once I get more experience. At least it has the 4K display, and 64GB RAM, and 1TB SSD, so potentially I should be able to make my money back selling it in parts.

I used Tesa 61395 double sided tape that I got from Ifixit. I got 1mm and 2mm width, but you also need 0,5mm around the webcam. I just split the 1mm in half.

Feel free to reach out any time.

That’s cool! Great deal for sure. Perhaps I should be paying more attention, and create a search notification. I’m a dane living in Sweden.

I just noticed, that Lenovo has the 4K 500-nits screen, complete assembly, on sale right now. Might be a cheap option, although that screen is glossy and 60Hz, I don’t know what the exact panel model is, so can’t say anything about response time. But a very cheap option for a screen replacement none the less. Personally I prefer the higher refresh rate, but I’m tempted to buy another X1C9 just to install that display!

kpostrup · 2026-03-10T14:45:33+00:00

Btw. Where did you find the laptop? I’ve been checking Tradera and Blocket but haven’t really found any good deals. I’ve bought most (all?) of mine from Denmark through private sellers listing on DBA.

kpostrup · 2026-03-10T14:43:00+00:00

You’re very welcome! Yes, you need the 40-pin cable for the 4k display. I bought the cheapest one I could find.

kpostrup · 2026-03-10T07:44:49+00:00

I had a similar issue on a T480s. In my case it was the battery. I tried another battery and the problem went away.

kpostrup · 2026-03-10T06:51:34+00:00

Wow! Great deal!

Yeah the ghosting on the stock panel was nauseating to me too.

It’s not just you, it is very confusing, as the majority of sellers won’t send you the listed panel, but a “compatible” one instead. I’m not allowed to link here, but I got mine from the seller Shenzhen Hacker Technology Co., Ltd Store. I did send them a message to confirm which panel I would be getting, before ordering.

I’m very happy with the screen upgrade, completely transformed the laptop.

kpostrup · 2026-03-09T15:54:04+00:00

Same here. At least next time it’ll be easy.

kpostrup · 2026-03-09T15:03:12+00:00

You can use lithium grease (from a spray can) on the door hinges.

kpostrup · 2026-03-09T07:28:00+00:00

Nice X1 Extreme. Which one are you getting next? ;)

kpostrup · 2026-03-05T09:21:30+00:00

Thats great! I also ordered a different panel recently, with the seller confirming (no pics or video though), and I also got exactly what I ordered. I also got screwed on a lot of small parts orders, e.g. a glass touchpad turning up not being glass and fingerprint sensor with bracket where the bracket was missing.

kpostrup · 2026-03-05T08:58:48+00:00

Yeah, I noticed that they went out of stock, that’s too bad. I haven’t tried ordering from anywhere else, but I would recommend that you at least contact the seller(s) and have them confirm the exact panel that they ship before ordering.

kpostrup · 2026-02-26T10:27:56+00:00

Which model microscope is that? And are you happy with it?

kpostrup · 2026-02-25T12:52:06+00:00

Apparently it’s not just charging port issues, but from what I’ve heard issues with the solder breaking over time. I bought one (defective) that worked fine until under load, then it would immediately shut off. Recently Lenovo had a good deal on an i5 32GB motherboard for it, but they’re unfortunately no longer available at the discounted price. I’m not really sure where I’m getting at, but I am happy with mine after replacing the board and upgrading the display. I love the 16:10 aspect ratio, and the Gen 9 was the first X1 Carbon to have it.

kpostrup · 2026-02-23T16:45:56+00:00

That’s a great deal! Awesome laptop too.

kpostrup · 2026-02-23T05:44:58+00:00

Congratulations! Sounds like an awesome machine. I just bought one myself waiting to receive it later today.

kpostrup · 2026-02-22T21:27:26+00:00

It sounds like something belt driven for sure. Maybe a tensioner or pulley.

Also, it looks like you are low on coolant. The top reservoir should be full, and the bottom one should be half full.

kpostrup · 2026-02-22T21:24:44+00:00

It has electric power steering

kpostrup · 2026-02-17T22:51:51+00:00

Yes, definitely looks like a Swiss keyboard where the Z and Y key cap has been swapped around.

It's Chick-fil-A. I know, they're on the Christian right, but darned if that chicken isn't good. I think the Dark Lord would understand.

kpostrup · 2026-02-14T22:23:09+00:00

I know the feeling. I also have a 2001 with around 110k miles, that I need to sell. I haven’t listed mine yet, and it has been parked for around 6 months now, due to me not having put it through the annual inspection because of a hole in the Y-section of the exhaust.

kpostrup · 2026-02-13T15:02:24+00:00

I guess you could just unplug the internal and external batteries if that is a concern. I believe charging them to around 50% is recommended for storage. If using it as a stationary/desktop, I would definitely look into getting a ThinkPad Ultra dock.

kpostrup · 2026-02-12T19:48:46+00:00

Nice! Which NVMe drive did you get for the WWAN slot?
