Lenovo Y50 Owners and Information Thread

Yup. I did receive the same one. It did take feel like a LONG time from order to shipment (5/23 to 6/18). Then it took about 6 days to ship to the U.S. from China. Not sure that their manufacturing and shipping process has improved from over a month ago, but I would say it is pretty close to whatever is listed on the Lenovo website. It is worth it though - you won't be disappointed. There is the caveat though that the screen isn't the best. It's useable and not horrible, but if you're expecting IPS, you'll not be happy.

Hope this helps.

 

If Dolphin is mostly dual-threaded, the CPU will automatically move Dolphin around from core to core. If you would like to lock Dolphin to 2 specific cores, all you have to do is use the Task Manger, go to the Details tab, find the program you want to control, right mouse click on it and use the Set Affinity function to set it to whatever core or cores you like. Will this make any significant difference? Probably not but it never hurts to try.

A 4th Gen Intel CPU is tiny and they put out an insane amount of heat. If one or two cores are approaching the 100C thermal throttling temperature, the adjacent cores are also going to heat up significantly. The heat has to go somewhere whether you are using all of the cores or not. Perhaps using the Set Affinity option to run your Dolphin program on the two cores that are furthest away from each other might help.

ThrottleStop does NOT prevent cores from idling down into one of the low power C States. When you are running a task, open up the ThrottleStop C States window and you should see most of your unused cores spending the majority of their time in the low power C7 state where power consumption approaches zero. There is rarely a need to try and out smart an Intel CPU.

ThrottleStop definitely does NOT feed cores a bunch of extra and unnecessary power. All ThrottleStop does is it tries to let your CPU run at its full Intel rated speed. That's the speed you paid for so you should be able to use it. When testing my Y510P, Lenovo's disabling of turbo boost "feature" seems to be triggered by power consumption and not by the CPU core temperature. Two threads of Prime95 is enough power consumption to disable turbo boost without anything running on the Nvidia GPU. When the Nvidia GPU is active the throttling is worse. The Heaven benchmark barely puts a load on the CPU but that is enough to trigger turbo boost throttling. It sounds like the new Y50 is more of the same.

If you think a 47 Watt CPU is too much power for this chassis, you might be able to use ThrottleStop to reduce your CPU from 47 Watts to 37 Watts. With the Y510P, it was possible to set the TDP to any value less than 47 Watts. If the PP0 Power Limit is not locked in ThrottleStop, set it to 37. The CPU will then throttle just enough to keep power consumption under that limit.

Your best bet is to use ThrottleStop so you can run your CPU at a speed that does not overwhelm the inadequate cooling solution. Instead of full turbo boost and overheating or no turbo boost and poor performance, you can use ThrottleStop to run your CPU at a speed somewhere in the middle. Send me a PM if you need some help.

 

According to the manual uefi is for Windows8 only. For any other OS you must use legacy mode.

 

I'm tired of seeing this when I'm playing games.
How do I prevent that message from appearing?

 

Hi there Y50 owners! Anyone here has problems with the Y50 FHD Windows 8.1 version's wireless while gaming? It seems that when I'm connected to a game in Dota 2, the ping skyrockets to over 1000ms sometimes to 2000ms on the router (know it because I cmd ping 192.168.1.1 /t) and once I disconnect from the game it goes away, it doesn't seem to be the router's problem because my other laptop is running just fine and tried another router at a friend's place and the Y50 gets the high ping as well. I've updated to the latest wireless Qualcomm driver on the Lenovo's website. Does anyone have an answer to this?

 

Yes, I bougth mine from Klick, everything went smoothly.

 

I did a fresh Win 8.1 install, what drivers I should download/install from lenovo website?

Is the 337.88 Nvidia driver good or I should try the 340 beta?

 

It seems this is Windows8/DirectX issue. I found some workarounds but they are for advanced users, do not try it if you're not sure what you are doing.

I have installed the windows 8.1 with the legacy mode and in SATA mode i had to change from ahci to ide. Now, the computer only boot and work in legacy and with ide sata. If i change to uefi or to ahci it simply crash or doesn't start. I have downloaded the drivers at lenovo support and it looks it's all working well. I just have noticed two things: In some moments the screen looks it has a little blur (even in other monitors), maybe software or windows 8 problems? And the nvidia driver that i downloaded from lenovo support is the 332.50. When i use the geforce experience to search for a newest driver, it says i already have the latest. But the 332.50 isn't the last, is it?

 

just made a fresh install of win 8.1 pro, after formatting....

Same problem in LOL - I don't even know what it actually is, it's not frame drop, its not ping raise.... But I am so pissed that I might return the laptop

 

-Hm, for W8 you should've used uefi, if it's x64 you should've enabled it in the BIOS as well. The OS should work fine with AHCI, maybe the Legacy mode you've enabled is causing the problem, not really sure.
http://download.lenovo.com/consumer...0-80_y50-70 touch_y50-80 touch_ug_english.pdf - that's the user guide, the bios/OS section is on page 26.
-no idea about the screen issue..
-Most people here including myself use 340.23 beta drivers directly from Nvidia.

 

From the description of the problem and the troubleshooting you did it seems it's not a network issue. If so it might be a video driver(Nvidia) issue, which drivers do you use? Did you try different versions?

 

The last version from the nVIDIA website 337.88. Apllied the fix file suggested in the Y50 thread. The version from Lenovo support can't be installed even with the fix file.... So no... I haven't tried other versions

I also think it's a video driver issue... but as I explained: it only happens in LOL(in every other game, it's fine). I'm starting to think there is some kind of defect in my video card as I didn't find anyone else experiencing such issue when playing LOL on Y50

 

you are not supposed to apply the updated NLTVi file to any other driver version. I don't get why you would try a fix on 337.88 but actually installed a different driver. either update to 337.88 or get 340.43 which can be installed right away.

the fact that you are having problem ONLY with lol shows that it's more likely to be a driver issue than a defect in graphics card, not to mention lol is more cpu extensive. either that or you just didn't optimize enough, you'll be having a much larger if your graphics card is defected...

 

I suggest you try Nvidia beta driver 340.23, you don't need the "fix" for it, you can install them right away.
I think that until Nvidia release proper drivers some games ought to have issues as the current ones a probably not optimized for many games and I assume some games are more "sensitive" than others.

 

I have used Legacy because UEFI didn't recognize my bootable pen drive =/. Is AHCI much superior than IDE? Cause i can't set it on without having troubles. And about the nvidia driver, i have installed the 337.88 driver, manually, following that other guide, but when i try to update to a most recent beta driver it says i already have the latest driver =(

 

I don't think your bootable USB drive is not recognized because of UEFI, it's most like because UEFI is set first as a boot option. I think you must enable UEFI but set boot priority for USB boot as first option. Not really sure though but you can try.

For maximum performance you should use AHCI...

I'd try uninstalling the current driver then attempt to instal the beta one.

 

Firstly I tried the updated NTLVi on 337.88 and with this driver I encountered the issue with LoL. I uninstalled it and tried with the Lenovo suggested nvidia driver (don't know the version right now), but it also didn't recognize the video adapter, so I decided to move to Windows 8. I had the exact same issue with Win 8 as well.

I also found this version: 340.52 and was able to fix and install it, but it was crappy as hell...


Also... I am not sure if the issue is only with LoL, haven't tried many games yet. Only LoL and Path of Exile. In the latter there is no problem.

 

I would just go with newest beta driver at this point and wait for the official one to come out.

 

Create your pen drive with fat32 instead of NTFS file system.

 

Hey guys, I just ordered my laptop off of the Lenovo site with student discount, do you recommend doing a clean windows install right out of the box?

 

Well, i have setted the bios to it's default and i turned off the notebook. Then, i turned it on with the novo button and then i selected the boot mode. In the boot mode it appears only uefi options instead of my bootable pendrive.

 

I tried with the beta you suggested: same s***

Screw that... I didn't pay 1300$ to sit and wait for some miraculous solution to come out. I'm returning it and I'm taking Asus ROG G550JK, which I originally intended to buy. I don't even know how I convinced myself to get a Lenovo, after the most horrifying experience I had with my previous Lenovo G550.

 

Hey guys, those of you who have the UHD and have the "blurry" chrome problem, here is the fix:

Chrome High DPI: How To Enable It In Windows 8, 8.1 (v34+) | Ubergizmo

Use the "Enable >hiDPI" link. It looks incredible.

 

go ahead, but if it's the driver's problem then there's not gonna be much of a difference

 

You do realize if the problem turns out to be really in the Nvidia drivers the Asus would have the same problem with LoL, right?
Also LoL does have some problems with new GPUs, there is a 50+ pages long thread in their forums - High-end Graphics Card FPS Issues - League of Legends Community
Just sayin.

 

There's a HUGE amount of bloatware that comes with the Y50, so I would suggest to do so. Lenovo made it easy to grab drivers off their site, so there's no problem with that. The only major problem I ran into when doing a clean Windows 7 install was that their NVidia drivers would not install no matter what I did (there was a post that helped, but didn't work) - so I'm stuck with Windows 8.1 for now. It's unbelievable that they still haven't updated them yet.

 

Well, first of all it's not even a real fps drop... As I said the fps rate and ping is a constant, at least that's what it shows.... When the problem appears I always check the FPS - it is unchanged... so that's what really puzzles me.... And also I tried 4-5 different nvidia drivers on both win 7 and win 8. Plus, I have checked numerous forums, articles and threads and no one seems to have such issue like mine...

Offtopic: Btw I see you are from Sofia, I am also a Bulgarian

 

Hmm I googled around and maybe your problem is network related after all, specifically the power options of the network card. This make sense(I had network related problems with another laptop and it was a power thing) and could also explain the lag-like problem you describe but no problem when pinging(btw what latency do you get?). Are you using wireless or ethernet? Check out that thread - Potential fix for lag spikes - League of Legends Community

Another thing you could try - I just played some Death Rally(the new version) and I've noticed I get horrible performance, it was barely playable on Low Graphics. It seems the game was using the Intel graphics so I forced the system to use the GTX860(Nvidia Control Panel, 3D setting and Physics from Auto to 860M), after that I could play the game on Extreme Graphics. Something you could try if the above doesn't work out.

OT: Always nice to meet fellow countryman on the forums

 

You should try what mrexcuse said:

Read this, especially the tips at the bottom. Then attempt to install in UEFI mode, if USB boot is enabled and there is no other OS the system should boot from the pen drive

 

Thanks for the tips, tried both- guess what? - same result

After so extensive troubleshooting, I really start to think it has something to do with that thread you showed me about high end video cards fps issues in LoL. I tried to play with uncapped fps and it really drops from 250 to 100, but it is not drastically, rather smoothly: step-by-step.

So do you also play LoL ? And have the same configuration on your Y50 as mine( I have posted them on my first reply to the thread). May I contact you somewhere else on PM to ask you a couple of questions ?

 

No, I don't play LoL. Yeah, same config( Lenovo Y50 | laptop.bg) but I replaced the SSHD with a Crucial M500 240GB.
Yeah you can PM me, besides this looks like more and more as a LoL specific issue and such discussion is not for this thread anyway.

 

That particular guide on about.com commits the cardinal sin when it comes to UEFI installation: It recommends using Microsoft's USB/DVD creation tool -- which creates NTFS formatted USB sticks, not FAT32 (as required by UEFI). Admittedly, they did add a note about this at the end of the guide.

The fact that Microsoft has not released a newer, UEFI compatible tool, has caused problems for endless numbers of users, and makes one wonder if Microsoft actually WANTS Win8.x to fail.

Rufus can create FAT32 sticks. Or they can be created manually, as described in the NBR thread linked below:

http://forum.notebookreview.com/win...ows-8-1-clean-your-windows-8-upgrade-key.html

 

Will using throttlestop give me significant gains in performance while gaming? I wasn't sure if today's games like Watch Dogs regularly tax the CPU and I don't want to potentially mess up my laptop for nothing

 

All true, that's why I specifically mentioned the tips at the end of the page
And yeah, Rufus is much better for that purpose.

 

Yes, yes, sorry. You did indeed mention that. I should have been clearer. I just wondered why about.com would even post guidance like that in the first place.

 

Ugh... guys (and gals, not to be rude)... I think I have my first errant pixel behavior on this thing. It is very strange though. It doesn't show up on black, just discolored brighter on all other colors. In other words, a small dot shows up slightly brighter (lighter shade) than the rest of the screen. At first I thought it was a droplet of water (I really have to stop spitting on my screen). But it isn't coming off and shows up more clearly on certain screen backgrounds. I've tried massaging, jscreen, udpixel - all to no avail. I'd be throwing a bigger fit if I didn't have to travel with this laptop this week. Maybe it'll go away on its own... maybe it won't. I've only had this for a month and was hoping that I would avoid any screen/pixel issues for a little while longer.

Perhaps anyone on this thread is a miracle worker and can make this go away so it doesn't keep staring back at me?

 

A word of care on Rufus: the partition type reverts to NTFS after you select the ISO image.
So, if like me you configure an options window from top to bottom, doublecheck all options before starting.
Took me 3 times before figuring out what was wrong -.-

Can you please test your touchscreen after doing that? I've found that by doing that, you break some touch functionality in Chrome. Specifically, the upper right portion of the menu bar was unclickable by touch and mouse I think.

 

I'd reinstalled my windows yesterday because of that AHCI issue. Now it's working as AHCI but the boot mode is Legacy Mode. I'd downloaded all drivers and programs and already installed on my laptop. Do you recommend formatting again just to boot on UEFI mode? Or this didn't have much of a difference? I know the AHCI has a great performance boost over the IDE, that's why i had formatted again, but the UEFI have that boost over legacy?
And thanks for all the answers so far!

 

I'm not too familiar with UEFI but I don't think it has anything to do with performance so no, I don't expect performance boost if you switch from "Legacy mode" to UEFI.
UEFI is more like an advanced BIOS if you will, I suggest you check wikipedia or some other sites for more information on the subject.

 

what i have seen is there's not a great performance boost, just in boot time. UEFI is 1-2 seconds faster on SSDS, so, i think almost no difference.

 

Here's a question for you guys:

Yesterday I had about 185gb free space of my Y50's 435gb available C Drive storage (512gb ssd - I didn't do a fresh install). Today I took a look and suddenly my free space dropped to around 135gb of free space for seemingly no reason. I freed up some space to get it back up to 146gb, but windows is telling me I have 289gb in used space when I can only account for about 230gb. Anyone have any idea where that 50-60gb of storage might have went and how I might be able to recover it..? Any help is appreciated, thanks.

 

Hey have you tried to unhide files
Which are marked as system files in the view settings.....

 

Yes, only revealed about another 1.25.

 

Hibernate files are usually very large.

 

You can try locating iunknown big files and such by using WinDirStat, SpaceSniffer or similar.
Hibernation, restore points, page file etc it could be any number of things.

It might be a known issue such as this one.

 

As members ATG and slazyel pointed out, the performance difference with UEFI is usually limited to a few seconds faster boot time -- and negligible on an SSD.

That said, it is quite possible for certain vendor specific hardware features (keyboard backlight, Fn-keys, power management etc) to depend on either UEFI or Legacy (CSM) mode: In other words, certain firmware features could be implemented only through UEFI, and the corresponding Windows drivers would require UEFI for these features to work. Conversely, some older drivers or utilities written for Win7 could have direct BIOS calls and not work properly in UEFI mode.

For that reason I normally recommend that Win8-delivered models be kept in UEFI mode, while Win7-delivered models be kept in Legcy BIOS (CSM) mode -- since that's how the manufacturer designed and tested them.

Note that I am by no means claiming that there is an issue with the Y50 when switching between the two modes (other than you have to wipe the disk and re-install Windows when you do). I merely want to point out that there can (in theory) be subtle issues unless Lenovo specifically designs and tests its drivers and utilities for both modes.

 

Hey guys, has anyone encountered a warning for lack of memory while gaming? It has happened a few times for me, I am playing Crysis 3, and not on the highest settings at all, more like medium at 1600x900...
