It is either a dying CPU or it is not seated properly, I don't have that tiny awful Torx screwdriver to check right now..

Torx? For what? The cpu tray? You could open the tray with a small slotted screwdriver if that's what you mean?

I've tried that, it didn't work, managed to get my hands on one of those screwdrivers, everything is flawless now, i7 4980HQ mutant is now installed, one missing pin didn't really do anything bad, from what I see.

I am thinking, what if I get an LA-9772P mobo, different screen and manage to get an RTX 4050 MXM, would that work? Ofc, I will disable integrated graphics, I am just not sure if it would work, because some people say it will only run in optimus mode and some say that it will work straight away, but you won't see anything until Windows finishes booting up.

I don't have the t1000 output directly to the laptop screen despite the edp connection. only when connecting an external display is there an image. So I'm using Optimus mode, not sure if it will work with 4050.
I want to order this card too😅

where are people grabbing the i7 4980hq mutants ? i need one for my alienware 18 atm i have a 4930mx  fine cpu but the 128mb l4 cache really helps with a lot of games plus the iris being as fast as a gt740 will make things feel less sluggish  since you have to use IGPU in windows also for those wanting 4050s in these i think we need above 4g decoding

They take them in China, but it's a lottery - I personally got 2 non-working processors, and I don't want to try any more. And I don't like the fact that only 2 memory channels work instead of 4. Decide for yourself if you need it.

I saw cases when there would be all 4 slots working, and it is usually on those ones that have a green interposer. Don't take my word on it tho, it is still a lottery. Mine has a black interposer and also has one pin missing after it was shipped, luckily it either wasn't used or it is not a critical pin.

From what I understand it will work, but it is not required. I am still trying to find a way to do it though.

I have just the two on the green board, and they didn't work in either the m4800 or the lenovo t440p, so I'm pretty sad. but if you say you've seen a working 4x channel maybe I'll still play that lottery.

Hey there everyone, so recently I decided to pull out my old m4800, and man oh man did the nostalgia hit me like a truck. I originally got this laptop from my dad's friend in like 2016/2017, since his work was phasing these out for newer models, and I heavily used it until 2022, when I needed more power for college, and invested in an XPS 9520. 2 years, a bunch of laptops later, the battery went cack in my XPS, and kinda needing a laptop, I decided to bring this beast out once again. The specs are:

i7 4800mq

8gb ram (never upgraded shockingly)

512gb no-name ssd

nvidia k1100 dgpu

1080p LVDS display (checked with the service tag)

running windows 10 enterprise 1909

 

Other than cleaning out the fans, repasting with PTM, and upgrading the ram, what are some other QoL upgrades that I should do? I really dig the red accents on the m4700/m4600 keyboards, so I plan on getting a backlit variant of that keyboard. I do have other machines that can do my bidding, but they're in various states of repair/function, as I have an addiction of going to electronic recycling centers lmao.

so, a couple days have passed, and I finally got the 32 gigs of ram, which set me back 40 bucks, and still waiting on the keyboard. as of right now, the laptop is snappy and does everything I want, from development to running virtual machines, and so forth. only gripe I have is the battery, but it's a mobile workstation, and an older one at that, so I can cut it some slack for that. the weight and the size aren't really a concern, even though I take it with me everywhere (even to college), and the keyboard is so nice to type on not gonna lie to you, brings me back to covid high lmao. I plan on installing debian or ubuntu, and I was wondering where I can find wifi drivers for this machine, as this laptop has a "proprietary" wifi card. I might swap it out with a newer intel 6x6 card, but I'd like to try to find the drivers before having to resort to that.

Do you know what Wi-Fi card it has installed presently?  Most cards should work out-of-the-box on Linux.  In any case, you can find an Intel 802.11ac mPCIe card for cheap (if that's not what it came with) and that will definitely work fine in Linux (Intel contributes drivers for their cards to the kernel).  You can even install a newer NGFF Wi-Fi card in the WWAN slot with an adapter, if you don't want to put a mSATA drive there.

 

If you can get NVIDIA Optimus working properly, this thing should have respectable battery life.  (That would be Windows only.  You need newer GPUs to use Optimus on Linux.)

So I have some horrible news guys. I have ordered an empty M4800 LA-9772P for 15 Euro (no CPU, GPU, RAM, storage, screen). 

 

I moved all of those things from my main machine, and installed some eDP screen from Lenovo for now. Because the new frame was untouched and wasn't worn in - that custom GPU heatsink from cicichen went in very snuggly, which I should l have noticed straight away. It tore a ceramic capacitor out of a T1000. Another pin from i7 4980HQ went missing, I guess it stayed in my old motherboard's socket. Laptop tries to boot into windows but fails, it had a WHEA BSOD before. I tried to salvage some pins from an old Socket M Pentium and now it goes to the login screen and shuts down. 

[MELOCODI]

This means that I have to find someone who fixes that CPU and get a 4050 MXM, old 4800MQ and M5100 go back in for now

Great. Now 4800MQ doesn't like RAM slot B, if there is a stick there - RAM error.

Where are you from ? I may try to help you both with capacitor and cpu pin.

About 4xxx series not needing 4G, where from you got info ? Did anyone already succeed with 3xxx series ?

Previously I thought for those to work it needs only correct vBIOS, but I saw many post with people trying make it work, but always they had some kinds of driver errors, etc. I myself do not tried it. In my opinion, for above Turing cards to work with our motherboards we need few things, firstly correct settings in UEFI, correct INF file moded, at least Ivy Bridge chipsets, appropriate hardware signals needed for card to POST.. and my bet is to use dGPU only laptops. Every laptop OEM have very different approach to how internal screen works with both iGPU and dGPU. And it also depends how oem had written motherboard software, which may be another obstacle.

I looked at PC game benchmarks, 3770k with rtx 4080 for example, downloaded bios update file, checked it with UefiTool, voila! Firmware from 2014 have 4G Decoding option.
