Hello Everyone!
I would like to share my experience with this machine in hopes that it might help those of you who are considering this laptop but not sure about its pro's and con's.

Specs (including aftermarket upgrades):
CPU/GPU: AMD Ryzen 2700u Vega 10
RAM: 32 GB, (2x16GB HyperX @3200Mhz CL 20, alas, running at reduced clocks @2400Mhz CL15, BIOS limitation)
Storage: NVMe SSD - Corsair Force MP510 - 480GB; additional 2.5" storage bay available!
Screen: FHD AG - Upgraded to 100% sRGB, 300+nit, 1:700 contrast, matte IPS FHD panel!
I purchased my machine with stock RAM and storage for 600$ during the ThinksGiving deal. As you can see, it's very cheap for a ThinkPad. So, what's the catch? Is AMD Ryzen's performance so underwhelming compared to its Intel counterparts? Let's find out!

As you can see these are some pretty interesting numbers. But it gets way more interesting. Looking at the temps, fan speeds and clocks I noticed a few striking things:
The CPU package never gets enough juice to perform at its maximum potential. It's limited at ~11W burst TDP, while according to AMD, it should be able to run @15W sustained and 25W burst TDP. Which means its being crippled by the BIOS to run at half its possible performance.
Correction! Upon additional testing it's been confirmed that the APU is set to run @22W sustained, with burst TDP of 25W. This is still below the capability of this chip, as the competition (i7-8650u) is able to burst all the way to 50W!
Not surprisingly, same thing is affecting the iGPU. It's never able to reach its maximum clocks of 1300Mhz, peaking at 1050Mhz during all my tests.
Temperature throttling? Not a chance! Temps never even reach 80C in this machine. This is considered ice-cold for a notebook CPU that can heat up to 90-100c before any real throttling kicks in. The fan doesn't seem to be stressed much either. The 2-piped heatsink is more than adequate to dissipate 25-35W. So why would Lenovo lock it down?
After some more digging I found out that it's not just Lenovo. Other vendors are doing the exact same thing! But not without exceptions. There's a couple of HP's with 2500u that run at higher TDP and show amazing CPU scores!
Whether it's for political or some other reason, I don't know and could care less. But I do care to unlock the maximum performance of this machine.
So, even with its crippled performance, the E485 show great CPU/GPU scores, with GPU twice as powerful as the Intel chip.
As for general build quality and features, please refer to this review, which I agree with for the most part.
I will add to this having 2 storage bays (1 full size NVMe + 2.5" bay) is not too shabby for a slim 14" notebook. As of today, you can slap 6TB of storage capacity into this machine (2TB NVMe SSD + 4TB 2.5" SSD).

Ok, I've switched to the dark side for the time being and moved to Linux on this machine.
Just wanted to let you guys know that in order to be able to boot and install Linux on Ryzen Lenovo's ( Lenovo, please fix your BIOS parameters!), you have to use the following flag at boot:
ivrs_ioapic[32]=00:14.0
All you do is hit 'e' at the boot menu and add this line to the boot parameters. You will also need to add this to your grub to make the change permanent after the installation by editing the /etc/default/grub file and then running update-grub. The parameter isn't my finding, all credit goes to Evilazrael.
I've tried Ubuntu 18.04, 18.10, Mint, Fedora 29 - all loading and installing without any problem. Currently using Parrot (I'm a security analyst, so that's my go to daily driver). It took way more tinkering to get it running on this laptop, so if anyone wants to try Kali/Parrot on their Lenovo's sporting Ryzen chips - let me know and I'll post a detailed guide.
Linux performance is just as amazing! Idle power draw is around 9-10 watt during light browsing. It's a bit higher than in Windows and does affect the battery life. But you can expect a good 4.5hrs of surfing in Linux and 5.5 hours in Windows. Still pretty good in my opinion as I rarely get stuck in places with no power.custom90gt likes this. -

A quick update after staying on Linux for 4 days.
Everything seems pretty stable. No WiFi issues. Bluetooth is working fine! BTW, Parrot OS 4.4 detected and installed BT drivers automatically (unlike Ubuntu and Mint). Temps are really low (45C at room temp of 25C), fan is inaudible unless running benches or playing games. I'm still trying to figure out how to reduce the battery drain rate, maybe should experiment with PowerTop or tlp. Next step - upgrading the screen! I really need a wide gamut 14" panel that could fit this machine. If anyone knows model numbers I could look for - please let me know!Vasudev likes this. -

Update!
I've just upgraded the screen on this beast to a N140HCE-EN1 rev. C1. It's a great panel and nearly a drop in replacement (just use the two bottom screws and ignore the top ones, the bezel will hold it nicely).
The difference is night and day, but I can't take a good picture to show you the colors, have no decent camera lol
100% sRGB
300nit brightness
700:1 contrast
Very good response
You can get it from ebay for about 50$, but I paid Amazon a nice extra bonus to get it delivered faster. No regrets so far.
On a much more exciting side, I've learned that it's possible to fully unlock TDP on this machine through linux! Still going over the process as it's not very easy, especially when running a non-standard non-Ubuntu based distro. I will be back with more good news! Stay tuned...Vasudev, custom90gt and Starlight5 like this. -

Here's the best I could do with my cellphone's camera. This is at 10% screen brightness in a brightly lit office, lol, anything higher and the image is too bright for the camera. I think this panel hits around 400nit in reality.

It's been reported that someone has already achieved a score of 740 in Cinebench R15 CPU Multi! That's a true full TDP quad core level of performance in a 28-35W package. I'm still trying to free up some time to make the changes, but my schedule is pretty tight at the moment. Wanna repaste first, then run benchmarks. Gaming, futuremark, 3dmark scores are coming soon! It's getting so interesting now. Wonder what excuse will vendors produce and how they are going to 'tackle' the situation? An underdog 500$ laptop is doing some serious butt-kicking both in the CPU and iGP sector. I'm expecting some MX150 and higher scores there.Papusan, huntnyc and Kuro Kensei like this. -

Thanks for the review, Kuro! I am buying a new laptop for the first time in almost five years and I have been eyeballing the E585. I am just looking for something with a FHD screen, good build quality, and good thermal and noise performance for ~$550. I considered stretching my budget to around $600 for something with an MX150 but that is really more than I need in terms of graphics power and the laptops at that price range with the MX150 aren't usually the most well-built machines.
I have been scouring the internet for opinions on the E585 and they have been few and far between but this performance information on the E485 has helped me pull the trigger on a 2700U-equipped E585. I should have it tomorrow and I am excited to see the performance! I will definitely be posting my experiences here for potential buyers to have more information.Last edited: Jan 17, 2019Kuro Kensei and custom90gt like this. -

So I have not had much of a chance to play around with it but I have to say I am pretty happy thus far. The keyboard is indeed the excellent Thinkpad quality one would expect. I have only used a couple of notebooks extensively in recent years, my old Pavilion G4 and a coworkers Swift 3, and it blows those two out of the water. The keyboard on the Swift is one of the main reasons I wanted to stay away from Acer. I have worked on that laptop extensively and I could not get used to the keyboard no matter what. I never measured but it just seemed stupid small. This one feels more like a full-sized keyboard. I also thoroughly enjoy "clackiness" of this one. The keyboard on the Swift had very "smushey" feel to it. I think the key travel is probably about the same but the mechanical-like feel on the Thinkpad is great to have.
The build quality, while I would rate it slightly below the Swift 3 overall, is still above average. I played around with some Aspires, Inspirons, and HP laptops at Best Buy before purchasing this and this is way better than those. It feels like just a step below a premium notebook. I would compare it to the current-generation Pavilions that I saw at Best Buy. The hinges could be a little stronger but I prefer these to the way too powerful hinges on the Swift.
The E585 is also a bit thicker than the Swift 3 but I prefer that. I do not really like the "ultrabook" like most laptops are moving towards. It is good on smaller form factors notebooks but in a 15-17" laptop, I want it to look a little bigger. I would buy a <14" laptop if I wanted a small laptop. I also feel like the thicker case will help with cooling, though I hope to be able to confirm that with tests tomorrow.
All in all, I am very satisfied with my purchase thus far. I bought this refurbished with a 2700U and 256GB NVME for $550 and I got pretty lucky with the warranty, it looks like whoever returned it bought this in January so the warranty still has a full year left. The single-channel RAM might be a problem but I am just going to drop another 8GB in there. As soon as I get that other stick and have some free time, I do plan to post a pretty extensive review. Thanks again, Kuro!Kuro Kensei likes this. -

Welcome to the club! Glad you like it! As for build quality, are there any issues, gaps, other imperfections? I mean, it's not a rubberized carbon finish, not a brushed aluminium, but a high quality plastic instead, which isn't necessarily a bad thing. Normally, I'm very picky when it comes to laptops, having owned HP Elitebooks, Dell Precisions and Alienware machines in the past. My E485 feels surprisingly solid for a plastic box. No creaking, no giving, no bending. Not sure I'd choose a X1 finish instead, even if it was offered as a free alternative. One big pro for me is that the finish isn't a fingerprint magnet! This is big, after a month of aggresive use, no greasy smudges anywhere, while my AW 13 with its rubberized surface requires wiping every 1-2 weeks.
Furthermore, I can press on the palmrest and keyboard as hard as I'm able and it doesn't budge at all. The absence of metal hinges is a relief for me. This setup will definitely last and won't loose its lid integrity. Thickness isn't terrible at all, 2cm for a 14" laptop is totally adequate. Wait till you upgrade yours to 32/64 GB RAM and add a second SSD! -
abaddon4180 Notebook Virtuoso
No imperfections in the build quality and it is definitely high-quality plastic. I can't find much, if any, flex throughout the whole chassis. It just doesn't feel quite as strong as the Swift 3 I have worked on recently.

Kuro Kensei Notebook Consultant
Update!
I've decided to delve deeper into benching to see how far this machine can be pushed. Had to grab another ssd and throw Windows 10 on it temporarily putting aside my hate for microsoft lol
So let's have at it. First things first, I've just repasted the APU with whatever 3rd grade paste I had kicking around. Lenovo did a terrible job with stock paste! No wonder the chip reached 79C in benches. It was a messy job whoever or whatever applied the factory TIM. Took me a while to clean it up.
So, here's the first stock run, still not touching the TDP or clocks, everything is pristine out of the box:
https://www.3dmark.com/3dm/33108567
GPU score = 3024!
Physics score=8414
Max CPU temp = 71C
Max GPU temp = 69C
Max power draw = 11.8W
So here you go, we now have a new reference point for stock clocks and TDP.
Next step - will unlock the TDP and see if we get a higher score.
Stay tuned for more...custom90gt likes this. -
abaddon4180 Notebook Virtuoso
I am very impressed with those temps. At stock settings, my E585 still went up to almost 80C.
-
Kuro Kensei Notebook Consultant
But the goal is to have it operating at full TDP and max clocks both CPU and GPU. So far, the GPU is stuck at 1000Mhz out of 1300. Going to try the DSDT method now... -
Kuro Kensei Notebook Consultant
Increased the TDP up to 25W, but not according to HWinfo64 (still not sure if those values are correct though)
-
abaddon4180 Notebook Virtuoso
My temps were around 85C before repasting with GC Extreme. How is your fan noise? It is possible the E485 has a more aggressive fan due to the smaller chassis. I have to strain to hear the fan on the E585, even under full load.
-
Kuro Kensei Notebook Consultant
Just realized what happened. The screenshot you see is @45W lol but didn't modify the current to match so it was hitting 85c but still not giving much performance. I should be hitting 720-750pts in Cinebench with it. Will do more testing today. At stock clocks @25W the system doesn't ever break 75C. -
Kuro Kensei Notebook Consultant
Another Update!
Just did a quick run at ~35W (unoptimized but increased current to actually make use of the unlocked TDP)
Cinebench15:
OpenGL - 48!
CPU - 709!
Max Temp 85C (room ~22C)
Will upload pics later tonight, my office blocks file uploads here lol.
But look at those numbers!
For reference:
Intel i7-8650U the direct competitor (and a much more expensive CPU) only achieves about 620pts in this benchmark, or almost 20% slower. This is a great indication of the raw power of the Ryzen 2x00u chip.Last edited: Feb 5, 2019 -

Cuz our CPU never breaks 15W while notebookcheck reports up to 40-45W draw on that 8650u.
Also, I've only just started tweaking and so far was able to go from the average of 550pts to 709pts. Wait till we get control of the voltages and start undervolting.
Will upload some more tonight. Just so you know, some of the i7-2700u owners have already broken 800pts.
What about iGP? Can your 8650u match my 3024pts in FireStrike GPU?Just teasing. I'm more interested to bench against a stock Nvidia MX150.

Still trying to figure out how to control the voltage in this machine. There's a discord server dedicated to this project with a couple of real gurus working non-stop to unlock the beast!

For now, 100% stable, no overheating:

Kuro Kensei Notebook Consultant
Ok, according to notebookcheck - https://www.notebookcheck.net/Intel-Core-i7-8650U-SoC-Benchmarks-and-Specs.242726.0.html
out of all 16 systems with i7-8650U not a single one above 700 in Cinebench15 and the average is only 618pts which is 20% below my score. And all I did, was add a few Watt to the TDP so that the GPU could reach its designed max frequency of 1300mhz on the core, instead of 1000mhz it was previously stuck at. That immediately resulted in 15-20% performance gain in games. I'm gonna run GPU benchmarks tonight and see if that MX150 can be beaten.
@Papusan, as for the 867pts you referenced, it's the world record [ overclocked/undervolted] result achieved by a Russian bencher. Luckily, he posted his XTU settings, so we can see that his CPU was running at 45W (maybe higher), undervolted, and completely choked the iGP to divert all package power to the CPU. Not to mention his usual tweaks of restricting the OS processes, setting real-time priority to Cinebench, etc,. This is NOT a real life score and can't be used as a baseline to judge the performance level of the CPU. Notebookcheck, on the other hand doesn't do any tweaks, simply running the benches as is, which shows the real performance levels. I do the same thing, while running all my programs in the background, not touching the task manager and can reproduce my score (720-735) 10/10 times. Still looking for a way to undervolt this CPU, this would possibly allow me to run it @45W stable without overheating, so we can start benching and comparing apples to apples even in the extreme case. Stay tuned...custom90gt likes this. -

Major Update!
Voltage control! - digging deeper into Ryzenadj (the program used to change the TDP and temp thresholds), we have discovered multiple voltage flags. One for the CPU/GPU, another one for RAM and I/O Controllers. We can now effectively undervolt the APU!
I was able to achieve sub 60C temps under full load @22-25W last night!
That's not all, we can now drop CPU frequency below its lowest 1600mhz, all the way down to 400mhz stable! This immediately boosts the battery life from around 4-5 hours to 10-13 hours! Someone had already tested watching videos on battery for almost 10 hours straight!
Here's the how-to:
We have only just begun! Will update the first post with all the new info shortly.User32 and custom90gt like this. -

If they had an A585 it might be a contender. I used to love smaller machines but once I hit my 50s 15.6 is my go to. I would love a 15" thinkpad yoga but they haven't made one in a few generations now.

Update!
More testing has been done. More discoveries.
Out of the box the system runs hardcapped at 25W (not 11 or 15W as I initially suspected) - here's what you can expect out of it without any tweaks at all :
This is already decent but seriously handicapped as neither the CPU nor GPU can achieve maximum clocks. The CPU can barely reach 2.8-3.0Ghz on all cores while the GPU core gets 1000mhz out of 1300mhz.
That is a serious limitation due to restricted max TDP of 25W for the entire APU. For reference both Intel i7-8650W and Nvidia MX130 can draw over 60W combined under full load to achieve their max frequencies!
Good news is E485 has a decent cooling system and can dissipate much more than 25W. Setting the TDP to 34W gives the following results:
This is whopping 10%+ increase in performance for both CPU and GPU! Not only that, this is totally stable and can be used 24/7 without overheating at room temp of 20c.
This is STILL below the nominated frequencies of the APU!
The GPU here only runs at about 1200Mhz instead of 1300!
The CPU achieves 3.3-3.4ghz instead of 3.8!
Unfortunately, in order to fully unlock the power of the chip, we need to improve the cooling by about 10-15%. The GPU can reach 3400-3500pts in FireStrike GPU, while the CPU can break 10000 in physics!
Just a glimpse at what's to come as we are working to improve the cooling:
So far it seems that the sweet spot for rendering/gaming/benching is around 34-35W to make sure you are getting 90% out of the designed performance and staying below 80C under full load!
To be continued...huntnyc likes this. -
custom90gt Doc Mod Super Moderator
How are you improving cooling? Have you repasted and such? Any luck on undervolting the CPU/GPU? Also about your screen, did you measure the 100% sRGB or is that the spec? I looked but didn't see anything with quite that color gamut. I'm pondering just picking up a cheap A485 with a 2500u (slower gpu) mainly because I really haven't gamed on my laptop in a long time.
toughasnails, ALLurGroceries and Dannemand like this. -
Kuro Kensei Notebook Consultant
Yes, you can undervolt it easily. At stock clocks, you don't even need it as the temps never go above 70-75C. My most balanced performance setting right now is 33W with a slight undervolt (using VRMMAX value of about 55k, I will explain how to use RyzenAdj app later). This achieves 3300pts in GPU FireStrike, 9000pts in Physics and you can game for the whole day never breaking 80C at room temp of 20C
About the screen, check this review, as it's the same model. Notebookcheck have about 5 reviews of different models using this panel and all of them come very close 100% sRGB. I don't have the hardware to measure it at home.
https://www.notebookcheck.net/Asus-ZenBook-UX3410UA-Notebook-Review.192282.0.html
2500u will give you a comparable CPU performance, due to the lower TDP requirement for the GPU part (Vega 8 only runs @1100 vs Vega 10 which runs @1300). But the GPU performance will be 10-15% lower. Before you grab a A485, however, please check some teardown videos, just to make sure the heatsink has two pipes. On our Discord Server we have some people with Ryzen laptops using a single pipe heatsink and their temps are out of control. So far, the consensus is, Lenovo E485 has the best cooling out of them all (compared to other Lenovo laptops, HP, Acer, Matebook, etc).custom90gt likes this. -

Good call on the heatpipes on the A485, looks like just the one. I guess I'll skip it and keep the X1E, lol.

With regards to the cooling mod, I've ordered a batch of supplies including PSG - Pyrolytic Graphite Sheets and Versarien Foam heatsinks of various sizes. Should be getting them in a few days and, if my calculations are correct, they should all fit inside without the need to trim anything at all! This is getting really exciting!
Also, tried running my steam games (about 45-50 titles) and they all run on high to max details just fine! Now, I don't own any of the really demanding ones like Crysis 3, Assassin's Creed Syndicate or Rise of the Tomb Rider, but it's really impressive to have so much power and flexibility to run from 400mhz to 3.8Ghz x 8 in a relatively light and very cheap package! Essentially, you can refer to notebookcheck's review of i7-8x50u + Nvidia MX130 to get an idea of the average performance of this APU.Here's the link to one such review - https://www.notebookcheck.net/Dell-...-8565U-MX150-Convertible-Review.372576.0.html
If you scroll down to stress testing, check the screenshots and you will see the CPU alone hitting 47W power draw under load. That 15W TDP is only good on paper and doesn't represent the maximum load. The GPU is also breaching beyong its rated 25W TDP under load. That is a combined load of 75W+. No wonder, most of these system throttle down due to overheating.
Stay tuned for more...Last edited: Feb 11, 2019Aikimox likes this. -

Another teaser! @36W combined -
What sort of normal temps do you get under 'light' load (web browsing, office/spreadsheeting etc)?
I'm looking at getting something to run at work - I have two Intel 6200U based laptops (Lenovo Yoga X1 and a Fujitsu E series) and performance is fairly meh. I want to run at least one VM on this so the ability to load it up with RAM is quite attractive. It's also very reasonably priced here in Australia at about 799AUD for the 2500U 8gb model.
Also, I'm hoping to drive two monitors with this - a 34" and 27" (3440x1440 and 2560x1440 respectively). I had thought this could be achieved with the HDMI port and a USB 3.1/HDMI dongle. I'm hoping the dongle won't be limited to 30hz or something silly...
Obviously I could spring for a X1 Extreme, but optioned up those things get close to 3 grand, and my computer fund this year has already been hit pretty hard!
Thank you for your interesting thread btw. Not a whole heap of info on the net on the E485's... -
