++ Main reason to consider:
Good package of extra features for a small gaming laptop under $800 (build quality, speakers, good keyboard, battery performance, noise levels and more).
— Main reason to avoid:
Currently, the 3D performance is lacking for an unknown reason. The display quality is also average at best, but it can be replaced (~$70-$80)
+ Good build quality (except the display cover which is average)
+ Good keyboard (better than the Y50 one) and good touchpad (but small)
+ Cool & quiet
+ Good battery running times (5-7 hours under light use)
+ Good speakers (but not great)
+ Good case build quality
– 3D performance is unexpectedly lacking (but it might get fixed in the near future)
– Display quality is average at best (but the display can be replaced)
– Keyboard is not backlit
– Only 3 USB port (1 of them is a USB 2.0).
– Not as lightweight as other 14.0″ gaming laptops.

The previous generation Y410P had a non-ULV I7-4700MQ and a GT 750M / 755M with an optional additional GPU which was barely seen (if at all). It was a bit bulky and weighted around 2.5kg which is around 0.3kg more than the Y40.
The new Y40 aims to be more lightweight and compact, but does it offer more hardware for the gamer or 3D professional? And how does the 1080p screen fares? we’ll see!
The Lenovo Y40 with a 90W power adapter
The Lenovo Y40 case itself is pretty firm an you won’t be able to make it flex easily, even the keyboard surface is pretty firm. Hinges are ok too. The screen cover is not as firm, but is at least as firm as the standard laptop out there. I’d say the build quality is above average.
The Lenovo Y40 looks more or less like the Lenovo Y50 with its stylish black-red gaming looks. The bottom and upper plates are covered with some nice pattern you can see in the images (sorry for the quality!)
Connection ports Only 2 USB 3.0 ports and one USB 2.0. HDMI is there but that’s all. Again in the Y40 too, a displayPort would be more adequate and many lower price laptops have them.
Maintenance and inner parts Removing the bottom cover reveals it all. You’ll see there is no mSata connection port, at least on this side of the motherboard.
Two fans are cooling the Lenovo Y40 GPU and CPU and in this case they are doing a good job. They are small and also very quiet under light load. The hot air is thrown from the rear of the Lenovo Y40 and is taken from the bottom. It means that you better have something to lift the laptop bottom from the surface it’s placed on, especially under medium/high load.
You can see the 256GB HDD and Intel 3160 WiFi card.
The Keyboard. The Lenovo Y40 keyboard is good and obviously better than the Y50 one. However, it is not great – the feedback could be better and it would have been nicer to the fingers and ofcourse, it is not backlit which adds to the ease of use. But generally, you can say it is good for a rather rapid typing, though maybe professionals would want something better. A note: I feel it is better than the Acer V7-482PG keyboard too (older version at least). The Gigabyte P34Gv2 keyboard was better too.
Touchpad. A standard touchpad, but works well. The surface itself is a button too and you can click it (except tapping it). It is too small to my taste.
The buttons, like in many other laptops, are connected. While it looks better, it’s not the convenient when a need to use both buttons rises up – however, it’s barely the case.
The Lenovo Y40 speakers are located on the upper laptop panel, just above the keyboard surface in the right and left edges. Sound quality is better than many other laptops with good low and midtones. Bass is a bit lacking as there is no subwoofer.
I could hear some artifacts in the sound while pressuring the volume too high, but I’m not sure it was the speakers’ fault. You could say that the speakers quality is above average. It is better than the Acer V7 and Gigabyte P34Gv2 I tested, for example, but still sounds a bit like a sound of speakers in a box.
The Y40 speakers are not that powerful, but they can fill a small room.
There are a lot of Lenovo software and crapware. Two useful ones are the Lenovo settings panel and the Lenovo motion control.
The Lenovo settings panel is good for controlling some basic features of the laptop, like Camera (brightness and stuff), WiFi, Microphone, Bluetooth and so on. I could get motion control to work, though, only with some Windows applications for reading and photo viewing – it works well as far as I tested (and I didn’t test a lot).
The Dolby interface is nothing to brag about, as it doesn’t really add much to the sound quality, but it gives you control over an equalizer.
I was using Windows 8.1 fully updated with all drivers in place. The 256GB SSD ensures responsiveness of the machine. Booting is very quick and working with a lot of stuff open is no problem.
One problem is that when I set the power mode on “power saver” or “high performance”, closing and opening chrome tabs might results in a split second stuttering. Not sure what is the cause
The test includes the 3DMark synthetic benchmarks and a small amount of games and the point is to give a reference benchmarks compared to other machines. For more numbers are available over the web in sites like Notebookcheck.com. I had no real problems and stuff. Generally everything run as expected.
CPU-Z and GPU-Z stuff:
You can see that the M275X is not recognized correctly really. The memory used in the M275X should be a GDDR5, but GPU-Z shows DDR3. If it’s true
(and it’s probably not), then it may be the explanation to the low 3D performance.
UDPATE: Yes, indeed, we are talking a DDR3 M275X version, probably. Check this Asrock mini-pc machine with M275X (core@770MHZ with GDDR5 VRAM) – link
Using the latest AMD Radeon 14.7 RC drivers, Windows 8.1 fully updated as I write these lines. HWInfo was used to measure temperatures. The settings I used in each game differ from one to another and the reason is that I tried to find the highest settings which still let you play smoothly. All games are tested with 1080p resolution.
I’ve removed unwanted results, like scene loading times.
The 3DMark results are obviously were tempered by some issues. These result are considerably lower than the 8850M results in the Dell 3540 review, which is slower. It seems like these are the HD4400 results and not the M275X results.
I’ve executed a more humble test suite for this one, as the Y40 has a problem with 3D performance while under load. The ULV I7-4500U becomes heavily throttled, probably in order to keep it under 15W of power consumption, though there is no thermal problem really and CPU/GPU temperatures were good.
These performance numbers make no sense, as the Dell 3540 had higher results with a slower Radeon 8850M (same chip, lower clocks), 4GB DDR3 and a slower I5-4200U which also throttles.
I’ve tested world of tanks using the highest settings only as I feel it suitable in this case. World of tanks usually doesn’t need a lot of FPS and the gaming experience is quite good on highest settings.
WoT felt totally smooth even on highest settings and over several maps.
Somehow, with LoL, the Y40 system plays well, running LoL on highest settings@1080p.
“high” settings show 27FPS as the lowest FPS I got, it’s usually around 33 and felt very smooth. Frankly, even on “very high” settings it felt quite well, so simply try both. Anyway, Crysis 3 lovers will enjoy this machine. The Y50 didn’t felt as good, maybe because the I5 (and slightly lower FPSs)
I have used bioshock built-in benchmark to test it. This is another example of the underperformaning I was talking about. You get about third of the Radeon R9 M290X performance, while having half of the hardware – something is wrong. Also, the results are lower than my Dell 3540 results with slower Radeon 8850M an an I5-4200U, 4GB DDR3. Makes no sense.
|Average FPS||Min FPS||Max FPS||Scene Name|
|14.10||7.46||29.95||Scene Change: Disregard Performance In This Section|
|17.89||15.84||19.81||Benchmark Finished: Disregard Performance In This Section|
|Average FPS||Min FPS||Max FPS||Scene Name|
|22.12||10.81||64.71||Scene Change: Disregard Performance In This Section|

I have used Thief built-in benchmark to test it. Again, third of the R9 M290X performance under very high settings, part of it is for sure the CPU throttling problem.
1. Prime95: Torture test, In-Place large FFTs.
2. Prime95 + FurMark 1280×720 burn-in test
3. Idle, “Power Saver” power mode.
4. Windows power mode on “high performance”
You can see that the thermals are pretty good, not reaching high temps even under full load. But again, the CPU is throttled, so without the throttle it could get higher. Anyway, the temps are good.
This is how it looks while running the Thief benchmark on “very high” settings:
The big lows are the in-between the two benchmarks I run. You can see that the max CPU frequency jumps up and down. I don’t know what it’s like that, but it’s there. It’s the same case with Crysis 3.
The throttling issue or some related issue obviously have impact on the 3D performance. The Y40 should be at least as fast as GT 750M GDDR5 equipped laptops and ofcourse, faster than 8850M equipped laptops as the 8850M has the same core, only with signifcantly lower clocks : 950MHZ vs 575MHZ-725MHZ. However, the 3D performance is lower than the 8850M and the 750M too, even compared to the 750M DDR3 results of the Acer V7-482PG (here).
We’ll have more information when the new AMD drivers and/or GPU-Z will show up. I’ll keep you posted
The case itself doesn’t get too hot mostly, except the left and left-upper parts of the upper panel mainly, with some of the left-upper of the keyboard too. Palm rests are kept cool enough and most of the keyboard too. I didn’t have any problem using it.
Under heavy load for long periods, the Y40 surface will get hot, though, especially around the left part.
Under light load, the Lenovo Y40 fans are hardly noticeable and under full load they spin fast, but they are not too noisy.
The Y40 default 1080p display is a rather ok horizontal viewing angles, but otherwise it’s not great. Vertical viewing angles are not good and colors are lacking. Brightness and contrast are also not that high, like in the Y50 1080p case. And like in the Y50 1080p display case, you can easily replace it.
Color coverage is not very good with only around 60% of the sRGB covered
The Y40 display can get contrast of around 1:360 more or less (in actual, it depends on the brightness of the screen and the surroundings). It’s not much and you can fill it. If you got one, I would suggest replacing the display.
The display does not fit professional use and frankly, even for the common use it’s not that great, as you might find it a bit stressing to the eyes in some cases. Moreover, other laptops for a much lower price have better displays.
The battery running times are quite good actually:
1. Light use : youtube playing some video, opening tabs, WiFi on, brightness on 90%
2. Idle – “green mode”, WiFi off, brightness on 60% doing nothing more or less.
Under light load, you could squeeze around 5-5.5 hours of battery, which is very nice and that’s including youtube and other stuff running – only reading and browsing light webpages will mean more hours. For example, as I’m writing these lines, the power consumption stands around 6.5W which calculates into around 7 hours of battery.
Idling will result in more than 11 hours of battery, which is very good, because it means that you don’t have to watch your laptop constantly and make sure it’s asleep just in order to save another half an hour for your class or something.
- Mainly the 3D performance / throttling. The 3D performance is considerably lower than what you’d expect in most cases, even compared to laptops with slower hardware.
- The 1080p display quality is average at best (but can be replaced)
For around the same price or a bit more, with display sizes smaller than 15.6″:
- 13.3″ : Clevo W230SS with a very good 1080p IPS display and GTX 860M. Bad speakers, heat and no OS for $1000, might be drawbacks. Also, it looks rather bulky. However, around trice the 3D performance and a very good 1080p IPS display.
- 14.0″ : MSI GE40, but it remains to be seen how’s the not-initial price. With 1080p IPS display and GTX 850M GDDR5, this is a very good option. (Read the MSI GE40 barebone review). The gaming performance is way higher around x2.5-x3.
- The new HP Envy 14 with an I7-4510U and a GTX 850M (probably DDR3), 1080p display, 8GB for $800 (with coupons)
- The older Acer V7-482PG-6629 for around $800 currently has a much better default 1080p AHVA display, around the same 3D performance (at least until the issues will get fixed), good battery performance and lower weight.
- The new upcoming Acer V7-482PG with GTX 850M will be interesting too when it becomes available and should offer a significant power advantage over the Y40 for around the same price or only a bit more.
And in general, all the machines under $1000.
The Y40 keeps me frustrated too, as the Y410p. Lenovo struggles to make something wrong.
Before we go into conclusions, I want to say that you can get the Y40 from B&N gold discount deals (you can see it here) which is cheaper. You can get it for $770 with the same specs except you get a 500GB SSHD instead of the 256GB SSD I have which was just what I could, get. I would definitelly suggest getting the 500GB SSHD version over the 256GB SSD one as you can buy an aftermarket 250GB SSD for like $100-$120 and then you’ll have both. So that will be my suggestion.
Now, let’s talk about the $770 version. It’s a nice compact gaming laptop for $770. It looks good, battery running times are good too, it doesn’t get too hot and under light load it’s definitelly keeps cool even in this hot weather, speakers are rather good for a laptop, keyboard is good and build quality is good too mostly. A good package for $750-$800.
BUT. At least currently, the 3D performance is more or less terrible. Even if we put aside the display quality, the 3D performance is simply too low for a $800 gaming laptop. There Y40 has a throttling issue of the CPU under load is one major factor, but it alone cannot explain the low performance. The Radeon M275X should have been at least as fast as the GT 750M GDDR5 of old days and it should have been faster than its slower brother the Radeon 8850M which is inside the Dell 3540 with its I5-4200U (throttled too) and it’s selling for a lower price (though with lower specs, RAM and HDD).
So what’s the deal? It might be a matter of drivers and the M275X not getting correctly recognized by the GPU-Z freeware might be the clue. We’ll keep you updated about that when new drivers and/or GPU-Z software comes up.
Now, about the screen. It’s indeed of low quality which is very annoying. The contrast itself makes reading a little bit harder than many other high end laptops. It shouldn’t be like that. However, unlike in the Y410p case and like the Y50 case, the Y40 display uses an eDP panel which can be easily replaced. I’ve already ordered a new B140HAN01.1 AHVA 1080p panel to test it.
Last point – competitors. A new Acer V7-482PG with GTX 850M for ~$900 would seal the deal more or less, for most people interested in this kind of gaming laptop. Also, the already available MSI GE40 and Clevo W230SS are much more powerful than the Y40 while offerning off the butt IPS display (the W230SS one is a very good one)
Final words. Hmm. What can I say. I’d say what I almost always say – wait. The new Acer V7-482PG should be interesting, but more than that, we need to see what’s going on with the drivers and 3D performance. Let’s say that it is fixed and we’ll get the wanted ~GT 750M GDDR5 performance level. Then for many people looking to spend less money and are interested in midrange gaming performance, for the right price of around $750, if no competitors are around, the Y40 can be interesting as it is a good package of extra features (see above or summary).
And about display quality thing – it can be forgiven if you’ll be able to replace it for like $70 to a good one.
