Hello guys,
I am a first time poster, but I do laptop repair and modification service for a living, and I have always preferred Mobile Workstations for my daily drivers. I have worked with or repaired a quite number of them, so I (kind of) know their weaknesses and strenghts even on the electrical level, and I have the ability to compare between each generation since 2007.
Back in 2014 I have purchased Dell Precision M4800. It was a good laptop with great cooling and internal access, I still love its industrial brick design. Unfortunately, after year or half or two years of usage everything started to break down in almost all aspects (keyboard delays, fingeprint recognition, PCH malfunction, multiple times replaced motherboard within ProSupport etc.). I have replaced it with ZBook 15 G1 that I have modified to same specification, this is what I use to this day. I saw no point in upgrading from Haswell to Skylake or its latter recycled variants, so I have decided to skip DDR4 era completely and wait out for new generation with DDR5 support and new architecture. I was hoping that it will be similar to transition from Core2 Duo Penryn era laptops to Sandy Bridge, that the performance and effectivity will be in a different league.
Well, here we are with Alder Lake, a downsized & spliced Skylake pseudo-next gen mashup with ridiculous thermals, bad memory controller and manufacturing variable so high, that the worst i7-12700K chips differ from the best ones by about 80-100W top load consumption and 25-30° Celsius on same cooler and conditions. Even Noctua NH-U12A is struggling to cool these down, and now they throw them in laptops. Again, ridiculous. I knew where this was going since day 1 of Intel mentioning mobile Alder Lake chips.
What we are going to end up with is that lets say, my (non existent) Dell 7770 will surpass your indentical machine just because I got lucky with a better, less leaking chip from factory. I mean, silicon lottery was always a thing in desktop OC & XOC circles, I respect that, but I have a serious problem when I buy a machine based on benchmark / review results and end up with something that is operating 30% below my expectations just because a CPU manufacturer cannot guarantee any consistency or QC. Not even speaking about durability of these things. I had to send several 12700K & 12900K´s to RMA because of faulty cores - not a great deal on desktop where you can switch out CPU within minutes, but in our world it sadly means motherboard replacement, which, if you want to keep the device for a longer time (after the warranty ends) like me, is worrying.
I was dead set on buying Precision 7670. I really was. I like 16:10 ratio and all the new features, but now, seeing this, I really had to rethink my situation, considering I still can squeeze one more year from my trusty old Haswell ZBook before retiring, even though its performance has become limiting to me. Who knows, maybe with the Raptor Lake it will be better and more consistent (though I seriously doubt that), otherwise I am screwed. At least there should be new GPUs available (with same ridiculous power draw increase). R&D of laptop cooling has not really evolved anywhere in the last 10 years, only thing that we have now is high speed fans with high blade count (and a lifespan of 2 years before the bearing gives up).
==================================
About replacing screens, yes, this is the way that all modern (2021+) laptops are build, with screen attached to lid via double sided adhesive. Good thing is that many of these adhesives return to their shape after pullout and are, in fact, reusable for a couple of times. Bad thing is that they (the original ones) are not available separately, only included in larger part such as replacement lid itself. You can use acrylic or butylene tape, but you lose the ability to remove screen without damaging it.
I also hope that in the next generation we will be able to choose 16:10 FHD IPS with high refresh rate, otherwise I will have to swap it out by myself. I do not want 4K in laptop, 2560x1600 is maximum for me.
==================================
About liquid metal - this is definitely a way to go, I lost count of laptops that I have modified this way, but on most machines you get a whole new level of thermals, silence and performance. On my ThinkPad X1 Extreme (i7-9750H) the result was that the CPU could draw 88W of power without throttling basically for an unlimited time.
==================================
PS: Is there anybody else that would celebrate the return of bottom sided docking port, just like M4800? I know I would. My ideal workstation would be a 16:10, 16-18" with ThinkPad design, M4800-like internal layout, IBM keyboard with hardware buttons for both trackpoint and trackpad, dedicated status LEDs and buttons (like T61p or older Compaq), 2.5" hotswap bay (M4800 had one), lid lock, desktop-like UEFI and bottom dock. I mean, these things are heavy beasts designed for workflow, why do they still pursue some unreachable idea of everything being thin & sexy like ultrabooks. Nonsense, at least for me. End of daydreaming, sorry.
