A clean install could resolve your issues.

A quick look at ebay.it shows this T540p https://www.ebay.it/itm/256482864764

Good enough? Or still too old?

cheaping out by using a U2405 though I like to think of it as environmentally sensitive. :) Personally I'm fine with using an old LCD monitor as long as it works and fulfills my requirements. :thumbs-UP: My current monitor is a second-hand Eizo MX220W (22" 1920x1200, with 1 Displayport and 2 DVI in...

Did you connect it like this: P1 G4 --> USB-C to DP adapter --> DP-DVI cable --> Dell U2405 DVI input If yes, I'll say that the problem lies between the USB-C to DP adapter and the DP-DVI cable. The DP-DVI cable only works on desktops/laptops/docks with a Displayport++ output. Note the ++ to the lef...

Personally, I'd rather not do delicate soldering operations on the machine I use for work (that's why it's best to have spares). If you think it's worth risking your T14 Gen 2 for a chance to get an internal LAN port, be my guest. TBH, I have the opposite of your problem: the Thinkpad I'm typing thi...

IMO there's not much you can do. I mean, where the heck would you even put the RJ45 jack on the T14 Gen2? This isn't like the T420 where there's a Kensington lock slot you can Dremel out or an RJ11 jack you can remove. You could try an M.2 Ethernet card like this one , but it's keyed for the WLAN sl...

It's probably bad.

I recommend not using it anymore.

Regarding the Device Manager issue, could be any of the internal devices that are connected via USB: webcam, Bluetooth, or fingerprint reader. It's generally a 50/50 between a cable/connection issue (connector not fully seated or worn cable), or the device itself is malfunctioning (which is reasonab...

Does your T400 have no battery (or a dead one) and use a 65w charger?

Try cleaning the keyboard. There may be something under the keys that's interfering with proper contact. If that doesn't fix if, you may have to replace the keyboard. That said, having replaced a T440p keyboard for a client last year, I'd say it's not a fun exercise.

1. If you can get flat heatpipes of the same general shape (including the bends) as the ones on the heatsink, great.

2. Use just enough thermal epoxy to hold the copper plates (or added heatpipes) in place, then use PTM 7958 everywhere else.

Theoretically, yes. In practical terms, probably not. I've seen extensive cooling mods for the T440p just to keep the CPU temperatures in check, one even sacrificing half the HDD bay for extra cooling capacity..

Liquid metal is too much of a spill hazard for that purpose. If I'm gonna spend on a project like this, I'd use PTM 7950 phase-change thermal pad, then somehow (gently) clamp the heatpipes together with anything I could think of (even twist wire). :lol: I've seen heatpipes bulge firsthand when I use...

1. If you're doing that, there's no need to wrap them in copper foil. 2. I'd rather use bare copper plates-- 3. The big question regarding thermal epoxy is its thermal conductivity, because it's very likely that it's worse than most pastes because of the presence of epoxy adhesive. I wonder if some ...

I haven't tried this but seen the photos of others who did-- the idea is to wrap the pipes together with copper foil tape . The "proper" way would be to solder some copper plates/sheets to the heatpipes to improve heat transfer between them, but of course not everyone has the skill set and equipment...

T14 Gen 2 uses USB-C docks. Why not use one of those?

I don't know what that port is, but on my 760XD, that area had the RJ-11 port for the MWave-based audio and modem card.

Those 15” sxga feel dim to me (dimmer than XGA) and then there’s the annoying jaundice the lg panels develop. Polarizer yellowing, or backlight ? Maybe a LED backlight mod ? Curious if the r60e celery can take a fast pentium M? I have a 2.26 dothan doing me no good, could basically make an R50 that...

Check the LCD cable FRU on your unit and compare it to the HMM parts listing. If you're lucky, the XGA and SXGA+ LCD cables are the same.

Welcome to the Thinkpads.com forum.

IMO it's best to keep it in one thread because you're basically working on a single project. You'll only need a new thread if you have a question that's very off-topic from the current one.

This solution sickens me.

II don't have the skills needed to fix a malfunctioning mini-PCIe slot, and can only marvel at the repair work you and other exceptional members post in this forum.

I'd try a fresh install. If it doesn't resolve the issue, then it could be the SSD.

What's the brand and model of the new SSD? Also, you mentioned it was refurbished, how's the drive health?

Question: does your T420 have a dead or missing main battery and a 65 watt charger?

Someone managed to make it work on a Sony Vaio Laptop: https://linustechtips.com/topic/1147704-m2-nvme-installation-in-mini-pcie-slot-wadapter/ This adapter was used: https://www.amazon.com/Ableconn-MPEX-134B-Mini-PCIe-Adapter/dp/B0779727FY/ Note that the adapter is for a B+M key NVMe SSD. Using it ...

IIRC it's best to upgrade to the same brand of touchpad--for example, if your W540 has a Synaptics touchpad, the replacement should also be Synaptics. I don't have a T440 (or any of that generation of Thinkpads as I absolutely hate the buttonless touchpad), but after reading the touchpad upgrade thr...

Well, two of my X220's are dead or dying while my X60/X61 variants are still chugging along despite their own sets of issues (mostly screen and battery issues)... Too slow for general use, screens don't have enough pixels for modern websites and applications, but still running fine otherwise. TBH I'...

You can use AIDA64 to find out the exact brand and model of the LCDs in your T490 and T440. Then use your favorite web search engine to look for their datasheets. Using those datasheets, you can find out if they both have 30-pin connectors (they probably are) and if the connectors are in the same lo...

It will work as replacement. They're both T430s motherboards with Intel-only graphics.

Every T430s system board will fit inside every T430s chassis. They're interchangeable in that way. IMO the only issue is if the new board has an nVidia GPU and your old board is Intel-only, which can be solved by buying the right heatsink. Note: the processor in the T430s is soldered to the system b...
