ThinkPad

Found when browsing Market-Place. Looks like a serious sellers. Although no mentioning of low-ballers and tyre kickers.

I'm experiencing a beep code error on my ThinkPad T440p.

I have checked the code error here: https://www.thinkwiki.org/wiki/Error_Codes_and_Beep_Codes

The code is 1 beep 3 beeps 3 beeps 1 beep. Suggested to be a RAM or RAM module issue.

The same RAM sticks work in my X220 no issue.

The issue started occurring after I attempted to update the CPU from an i5 to an i7. It is possible I forgot to remove the CMOS battery or Laptop battery when I did this. It was a few months ago, so I can't remember for sure. I have since put the i5 back into the laptop.

I tried following the suggestions here: https://www.reddit.com/r/techsupport/comments/bhy11i/lenovo_thinkpad_t440p_bios_beepsq

Unfortunately they did not work. I don't think the issue is a CMOS battery issue. I am thinking it may be a motherboard issue.

What happens when I try to boot it up, I get the 1-3-3-1 beep code. Nothing happens after that. The screen is blank and the power button is green.

Is it likely that the motherboard is dead? It's the only thing I can think of, at this stage. Is there any other things I can do to test it? If I am confident enough that it is a motherboard issue, I may decide to get another motherboard. But I don't want to spend the money when I am not absolutely certain, if that is the cause of the problem in this case.

Does anyone have a copy of the original Windows 7 recovery media for the X1 Carbon Gen 2? I can find gen 1, and most other later gens. But not this machine. Currently it's running it's factory install, but it's horrendously slow and I'm not fully sure why. And sadly the built in create recovery media option says there's nothing to be found.

Does anyone else have any experience with these machines? Were their SSDs always so horribly slow? 550mbps read is good, but 100mbps writes is bad even by 2013 standards. The touchbar takes what feels like ages to respond, and with age has discolored in a really gross way. Overall it seems like a pretty well built machine. But man, what was Lenovo thinking?

My webcam does not work. I’m sure it’s a hardware issue as it persists in windows and Linux. I already reseated the camera and it still happpens.

The other issue is that it seems the keyboard randomly ignores key presses. I’m not sure what the issue is, but it’s frustrating to type on as it happens randomly and a few times ever couple hundred characters.

Can someone give me some advice on how to self repair these problems? My goal is to sell the laptop once it’s repaired.

Other than those issues, it works really great. I just want something a bit thinner.

I have a BASE model T14 gen 1 (1366x768 screen, lowest end i5, base ssd etc) and I was wanting to eek out a bit more performance out of this machine. It's quite thermally constrained with longer loads despite being the base model, and it's fan seems to barely move any air at all.

I know along with other T series you can install the heatsink from the higher end models with dGPUs and get much better cooling. Has anyone here done the same and can report back on performance differences?

Part No 5H40W36701 is the heatsink I have. Part No 5H40W36700 appears to be the model for the dGPU macines. Lenovo lists it as $61.16 for this part, but ebay has them for a little over $30. So the next question is it enough of a difference to justify it?

Sorry for a dumb title. I'm considering two versions of Thinkpad Z13 - one with 3k OLED and another with FHD IPS panel. The first one has obviously a better display quality and gamut range but version with IPS will provide more battery life.

What do you think about panels like that on a 13" laptop? Are they noticeably more pleasant to interact with?

I like to have good battery life but if OLED is to blow me away maybe I should pick one.

I will be using Linux btw.

Edit: I know the only one to answer this question is me but I would like to hear your input and maybe learn about things to consider.

What is a good source/seller for the EU? The nipple included with my qwerty replacement board for a T480 won't last much longer... The original one from the qwertz board is lost in space. Any recomendation?

Edit: found 10 nipples for 3 bucks on ebay. Shipping from China. Probably lousy ones...

I currently have a 128 SSD on my computer, but I just bought a new 512GB SSD, and I've already installed a temp linux distro but my computer doesn't boot it, it send me to the screen that you see in the pictures. I don't know what's the problem, and I already explored the entirety of the BIOS to see what was going on.

I just bought a used "faulty" T430.

It doesn't turn on at all (no lights, no sounds, no fan spin) and when I tried to turn it on with only the critical components (motherboard, power adapter and speakers), I got the same result.

I've also examined the power area on the motherboard, and it seems like 20V is getting delivered to the motherboard just fine.

But I've looked at the motherboard thoroughly, and I couldn't find a single part of it that looked bad.

Is this definitely caused by the motherboard, or could it be an issue with another component like the CPU?

What is the port to the right on the two USB C ports? To the left of the RJ45. (ThinkPad T480s with integrated graphics.)

Edit to add: thanks in advance!

Hiya :)

Finally finished upgrading my Lenovo ThinkPad T470

32GB RAM 1TB SATA 2.5" SSD 512GB NVME SSD (WWAN 2242 Slot, Everywhere said NVME don't work, well :P ) Intel AX210 WiFi 6E 160Mhz Card

Any Thinkpad user here using their Firewire port? What would you use it for? I read that we can make ad-hoc connection between two computers.

Left: X61S with 4GB ram.

Right: T530 with a bunch of upgrades.

This is my first thinkpad ever. I chose to possess T480 long ago, but my Thinkbook 14s was working fine, and also T480 was not available nearby me (Nepal). Finally when I got a chance to order one from Malaysia, I instantly chose T480 for 1300RM. For Nepali market, it is super cheap (about $270). This is a 16/512 GB variant with NVMe SSD, touchscreen and matte display (!) and processor i5 8350U. Very happy after about 4 years of waiting.

Took me a while to be a man of culture.

BTW the smaller Thinkpad is L13 yoga Gen 2 which is for my sister-in-law. And I gave Thinkbook to my brother.

I'm about to replace my T470s and am leaning towards a T14s AMD G4 with Ryzen 7 Pro 7840U and IPS panel.

My main concern currently is thermal management regarding volume and possible throttling. Does anybody know if there's a significant deviation in the tree models? Might the T14 or P14s be much better in cooling the CPU and therefore achieve significantly better (long term) benchmark results?

Gotta have extra trackpoints on hand at all times just in case.

Replacing the crappy panels that come with the T480 with a better 4K panel is a somewhat popular mod, and it seems that most people opted for the BOE NV140QUM-N53 as the replacement panel.

However it is not the best 4K 14" 16:9 panel, I think that would be the AUO B140ZAN01.2, as according to panelook.com it has better brightness and color gamut while having only slightly worse contrast.

The B140ZAN01.2 is a 10 bit (8bit + frc) panel and i was a bit concerned that it would not work as as far as i know no one had put a 10bit panel in a T480 before.

I had ordered a B140ZAN01.2 from aliexpress a few weeks ago and it arrived today. I have not yet fully installed it but i tested outside the laptop, and i can confirm it works, and despite being extremely bright at 600cd/m² it did not blow the backlight fuse even at full brightness.

I will post an update on the full replacement process when i get around to it.

update:

I have got the new panel installed, The installation process was nearly the same as detailed in this reddit post: https://www.reddit.com/r/thinkpad/comments/jde1a9/the_hackinpad_t481_heavily_modded_t480/
The panel used in the post is a different (worse) version of the one i used and has identical dimensions.

The end result is good and i dont think anyone could tell the panel has been swapped by just looking at it. The only issue is that the panel is offset up by about 1mm, this is due to the pcb at the bottom being taller, i could open it up and remove more of the raised plastic bits on the inside of the lid to get the panel better aligned but the slight misalignment is not that noticeable so i will just leave it be.

The panel itself is quite comparable to the 2560x1440 hdr 500nit panel (AUO B140QAN02.0) in the x1 carbon gen 6, the biggest difference is that the B140ZAN01.2 gets even brighter, color performance and black levels looked very similar.

If you have any questions or would like to know how to do this mod yourself feel free to ask, i left out a lot of details that have already been mentioned in the other T480 4K mod posts.

Bought it used (but literally like new, not even a scratch) for €180 and then slapped on it 2x32GB RAM sticks (Patriot, DDR4 3200Mhz, €68 for the two sticks), a 1TB M.2 2280 (WD_BLUE SN570, €54) and a used Intel AX200 Wi-Fi card (€15) for a total of €317 for the laptop + the upgrades (+ this dock as the seller included it with the laptop: https://support.lenovo.com/us/en/solutions/pd500180-thinkpad-hybrid-usb-c-with-usb-a-dock-overview-and-service-parts). I also did a repaste with some Noctua NT-H2 paste I had laying around.

I'm really happy with it right now, and yes the T480 does support 64GB of total RAM despite the official website and even the system itself reporting 32GB as the maximum installable capacity, and yes you can also go for higher frequency sticks as long as they are DDR4 as they'll downclock themselves to the max supported frequency of your laptop anyway, this is important because old DDR4 sticks are rare and expensive.

I purchased a tube of thermal paste for my Xbox 360 and would like to reapply the thermal paste on my X200s. I am struggling to find videos about reapplying thermal paste on it. Most videos seem to be complete disassembly videos that remove the motherboard but I am wondering if this is necessary. There is one post on Reddit that seemed to detail the processes but it has been deleted.

I would appreciate any advice or videos you would recommend to walk me through the process.

My Thinkpad X250 suddenly stopped working one day. I opened it and I saw this chip left to the Ethernet port. It seems like it has exploded or something like that. Before it stopped working, sometimes it would get as hot as 95°C. Do have any idea of why it would stop working and if so, how I could repair it? Thanks in advance.

I wonder if anybody has done this before

The T14s speaker I have are Dolby Digital speakers and honestly not too bad and the T495s are just standard and could be better.

i plan to swap these over but I was wondering if the its possible to swap these? not tried yet and want to see if anybody had done anything similar?

It looks like a typical thinkpad rubber back, but with the x1's "carbon fiber" design cutting through it with a wide diagonal line. Google only gives standard rubber backs. Anyone have any idea what this version of the design is called?

I'm planning to purchase a used T480, and want to know how the battery life would be on Linux. Online I see a lot of good numbers, and I am considering carrying multiple of the external batteries, but I want another opinion. Also, do you have any recommends on a good price to "go for it" and any other laptops to consider (up to but preferably well under 600 USD, good battery/portability, linux) to consider.
