M4980

Decided to try the Forza Horizon 4 benchmark on ultra settings with my Quadro T1000, pretty impressive results I only use -35mv, think my 4810MQ is pretty bad. Starts crashing below -50mv if i recall correctly

I've been using a KingSener branded FV993 battery (97Wh/9000mAh), has been working great for me. If you're actually looking for the best in terms of capacity though, the CMP branded batteries found here claim to have an extended 112Wh/10050mAh capacity. https://www.ebuy7.com/item/561806111328 Haven't seen any reviews of it though or confirmation that the capacity is accurate.

Can confirm the Honeywell 7950 is really good, I've noticed much better thermal performance with the CPU (switched from Kryonaut iirc) However, the hot spot on my T1000 is still 98c under max load after the change, causing throttling. Pretty sure I have good die/VRAM contact.. Can any other T1000 owners report on their temperatures under max load? Considering joining the CPU and GPU heatsinks tbh

Very informative! Thanks guys, it's not something I considered before really. This could possibly explain the sudden death of my PGA i7-4980HQ tbh, it has all of the symptoms of a dead CPU memory controller, and I previously ran LM for almost a year without re-applying it. Perhaps moving it into my M4800 was the final nail in the coffin. The more you know! For future readers considering the Honeywell pad - make sure you cut a piece slightly larger than the die to account for almost inevitable creases as you apply it 😛

Oh dang, that's not good. I might need to redo the CPU and GPU dies then... It was super tricky to install so I missed the edges/corners on both, exactly as shown in my picture.

Got the Anshu 180w GaN + SiC charging adapter for my M4800. It's much smaller and lighter than the original Dell 180w adapter and seems to be working well so far. I've also switched the thermal paste in the laptop to the best option available right now, the Honeywell PTM 7950 thermal pad (non-conductive phase changing material). This also seems to be like a huge success (temps are far lower) and is supposed to last years without any degradation. The only downside to this is that it is quite awkward to install, however there is also a paste version which is probably far easier, possibly at the expense of some additional gains. Both of these items are only available from China on Aliexpress/Ebuy7 - I got mine from Ebuy7 as it was significantly cheaper. Took 12 days to arrive.

Yep, I'm not sure how this will affect the modified ThinkPads. Right now, it seems like they are still operating - they shipped out the 10th gen X2100 orders in April. http://www.cnmod.cn/ https://www.facebook.com/lcdfans/

This notebook is in the GPU upgradeable section but has a soldered GPU (also thank you for creating the list)

Wasn't sure if this was considered general or off-topic but the 51nb site as well as its forum have had their web addresses unreachable for quite a few weeks now - doesn't look like it'll be returning soon either. They had a good amount of resources pertaining to notebooks and tech from Chinese users, so it is a shame to see it gone. I cannot see any news online regarding its closure, nor any messages on their social media pages. However, there is a thread here that explains that the domain has ClientHold status, meaning it is suspended: apparently a six-month suspension at best so perhaps it will return next year. A poster on that thread also claims he may be able to cooperate with Lichuang regarding the matter (perhaps he is referring to modified ThinkPads)

So, the NV156FHM-N4J display would require 10.75 Gbps bandwidth, which the Intel HD 4600 is theoretically capable of via eDP (it's actually capable of up to 4K@60Hz as per Intel's specification). But my confusion stands as to why the QHD+ panel requires the discrete graphics mode - see those in this Dell forum discussion. How far does this limit go? Am I able to install a 1080p 144Hz panel? Does anyone here have the resources required to find out? My assumption right now is that I will need to stick to 30-pin eDP displays. EDIT: I am now fully read up on the matter, I just didn't read hard enough b4 Conclusion: under the assumption that newer MXM GPUs such as the RTX A2000 will also be unable to work in discrete mode on this laptop, resulting in 40-pin displays being incompatible, a docking-connector hijacking eDP board similar to those used in old ThinkPads should be created, I am going to look into it. As the M4800 has such huge bezels, I'm inclined to believe that the LP170WQ1-SPA1 17.0" 16:10 2560x1600 display would fit inside the M4800's lid after relocating the antennae, removing the webcam, shortening the hinges, and removing obstructions. The result would be funny to say the least

Probably gonna get a 1080p display instead, looking for something 400+ nits ideally. Came across the Innolux N156HCE-GN1 from ThinkPad P53/P1/P15/T15g/X1E which is a 60Hz, 500 nits, 30-pin eDP panel. Technically compatible, anyone tried it with the M4800? If not, which display upgrades have been confirmed on the M4800? I'm aware that some people use the B156HAN04.2 120Hz display. EDIT: Looks like NV156FHM-N4J might be the move. 500 nits 144Hz matte G-Sync panel. Might try it out soon. Anyone already tried it?

I always go with the KingSener brand from Aliexpress. They seem reliable from my experience and have the genuine capacity stated https://kingsener.aliexpress.com/store/1898372 Got this 9-cell few months ago for my M4800.

Hello guys 😄 Does anyone know anything about the Quadro T1000 upgrade not working with the QHD+ display? I saw it discussed on 51nb briefly. I tested out the LG 156QHG display from the 1440p Alienware M15 R6/X15 R1, the connectors matched (pitch and pin wise) but I got a black screen, no boot, fans spinning for 5 seconds. The T1000 QHD+ bug could explain why I guess. Either that or display is incompatible for some unknown reason

Installed the Taobao version of the ExpressCard to NVMe adapter in my M4800 with a 512GB Samsung PM991 SSD, works great and hotswaps fine too. Not going to try booting from it but I assume it cannot do that? If I test it, I will post the verdict. Next plan is to modify the Dell ExpressCard dummy to accept the PCB, this'll make it much easier to remove and also look seamless

I voted for efgxt.net as I believe it sounds the best out of the given options, furthermore I think the notebook branding could be redundant. 😺 Users will quickly see that this is a specialist laptop forum due to its insightful discussion revolving pretty much all aspects of laptops (perhaps it should also include small laptop icon in top left of top navbar). It should also spread via word of keyboard that this is where a lot of notebookreview forum users went, so they will already know this is the "notebook revival". i would like to thank everyone involved with this forum for creating a new platform for notebookreview forum users. it looks great so far 🙂
