Lenovo IdeaPad Y410P Owners and Information thread

anybody notice games stuttering every 10 seconds or so since the last NVIDIA driver update? I've done a clean re-installation of it as well as cleaning out my computer with ccleaner. Still noticing lag spikes about every 10 seconds no matter what game. Computer usage shown in task manager isn't showing anything alarming either so I'm rather confused where this is coming from.

 

I've had some weird flicker/stuttering in a few league games, but alt-tabbing back and forth a few times fixes it.

 

nevermind.. rolled back to last nvidia driver and it's still doing the same thing. Guessing I most likely won't get an answer to this but doesn't make sense how this occurred for no reason. meh, time will tell I guess -__-

 

SMT pick-and-place robotics were around during the late 1980s when I was working at IBM-Austin, although nowadays more printed circuit board components are soldered using ball grid array packaging instead of passing them through a wave soldering machine. During the 1980s, only a very few components, usually larger irregularly shaped objects such as the ISA bus expansion slots, were hand-assembled prior to wave soldering back then. But both back then and right now, you still need humans at the end of the robotic assembly to scrutinize the soldering, perform X-ray inspections, and perform various burn-in and testing of the assembled system.

Lenovo, just like HP, Dell, Asus, and other PC manufacturers, now have to compete with tablets and smartphones for consumer dollars. Only Apple has the kind of fervent customer loyalty that Windows PC manufacturers can only dream of, and this fierce brand loyalty lets Apple charge non-discounted prices for their gear. But I think that even Apple is feeling the pinch on their Mac sales with consumers buying more tablets now.

For a Y410P packed with an i7-4700MQ and GT755M with a great price of less than $800, I certainly do not expect an IPS or wide-gamut display... although it would have been really nice if Lenovo offered that as an upgraded configuration. Full HD is nice on a display that is 15" or larger, but full HD is overkill on a 13" or 14" screen. But if you want it, you can get a 13"/14" laptop with the Y410P's CPU/GPU specs and an HD IPS display starting at around $1100-1200. I plug my Y410P into a prosumer-grade $800 24" IPS monitor for photo and HD video editing.

I received my replacement Y410P today; the original laptop had a non-functioning 24-GB M.2 SSD card. The replacement is supposed to be identical in configuration to my original Y410P. But in comparing both laptops side by side, I immediately noticed that both the keyboard backlighting and power button light on the replacement were much more dim than on the original laptop. Both keyboards also look and feel considerably different. The Y410P Hardware Maintenance Manual lists six different FRU part numbers for the backlit keyboard part, so there are significant differences and variations in the look and feel of keyboards that Lenovo is using in various Y410P shipments. If you go to Lenovo's parts lookup Web page at Lenovo Support - Parts Lookup (US) and enter your laptop's serial number, you can get the full listing of all part numbers used in your laptop. Below are the two different keyboards that I received for both my original and replacement Y410P:

Original laptop's keyboard FRU part number: 25205514 Description: JMET2B9USB84KeyDualColorKBD
Replacement laptop's keyboard FRU part number: 25205515 Description: DFT2B9USB84KeyDualColorKBD

Original laptop's keyboard appearance: White characters on black keys.
Replacement laptop's keyboard appearance: Slightly pinkish characters on black keys; the characters look more red than the original laptop when backlit, but do not have as much contrast and the keys' characters do not look as crisp in a dimly lit room when not backlit.

The original keyboard's backlight is much brighter than the keyboard on the replacement laptop. The low backlight level on the original laptop is comparable to the high backlight level on the replacement.

Original laptop's keyboard feel and action: Firm with a crisp bounce, with twice the up-down key-press travel compared to the replacement's keyboard.
Replacement laptop's keyboard feel and action: Soft mushy key action, with about half the up-down travel compared to the original keyboard; some keys, such as the space bar key, are very soft and only go down very slightly when pressed.

The original keyboard has about twice the key-press travel than the replacement's keyboard because each key is raised up higher than the replacement's keyboard. Because of each key's higher height, more red color is also exposed around the sides of each key on the original keyboard, and I think that this extra bit of red around each key looks more attractive than the lower-set keys of the replacement keyboard, both with and without backlighting. Although everyone has their own keyboard preferences, I like my original laptop's keyboard with its firmer action and crisp bounce FAR more than the mushy soft action of the replacement laptop's keyboard. The replacement laptop's keyboard feels so mushy that I wondered if I received a refurbished laptop as a replacement. But the keyboard and all external parts are totally scratch-free and look new. When I opened up the bottom cover of the replacement laptop, all internal components also look new and the two copper heat pipes are totally shiny new and untarnished. My original laptop had a dead 24-GB SSD, while the replacement laptop's SSD works correctly. Since I really hate the mushy keyboard on the replacement laptop, its weak backlighting, and its dimly and unevenly lit power button, I swapped the M.2 SSD drive between both laptops. When I received my original laptop with its dead-on-arrival 24-GB SSD card, it took a very long time to cold-boot - from the moment I pressed the power button to the moment I got the Windows login screen took 2.0 to 2.5 minutes; the laptop would just hang there as it tried to interact with the dead SSD cache. Now with a functioning SSD cache card, after pressing the power button, it pauses at the Lenovo logo and spinning busy icon for only 7 or 8 seconds before I get the login screen. The replacement laptop now takes at least 2 minutes to cold-boot after I put the dead SSD card back inside it. I will return the replacement laptop back to Lenovo now and keep my original laptop.

So one moral of my story is that if your Y410P's keyboard is either too firm or too mushy for your preference, or has white or pinkish white characters on the keys, or has dimmer or brighter backlighting, you should know that Lenovo is using various keyboards on the Y410P that differ in how they look, how they feel, and how they are backlit. My two laptops both are the 59399853 configuration, and both were made on the same date (December 13 2013) and originated from the same Factory ID, but they both still had markedly different keyboards.

 

Wait, will the Y40's 1080p panel work in the Y410p?

 

I believe only the Intel graphics work on battery. You need to be on charger for the Nvidia to kick in.

 

I was not sure how much SMT tech you used in the 80s, surely the components were not as small.

Yes, Lenovo has multiple manufacturers for the keyboard. They probably do have different feels to them. They do this so they don't run into inventory problems by stocking only one manufacturer's keyboard.

Panelook doesn't have 3840x2160 panel in that size range in their database so I can't make a definitive statement on it but according to Wikipedia dual link LVDS (which is what the y410p has) can support LCDs with resolutions up to 2048x1536, which is far exceeded by their new panel, so they would need to use eDP to use the panel on the Y40. Seeing that they are using eDP on the Y40 (presumably), they probably also use the same 14" FHD panel that is in the Alienware 14 because as we have covered before, there are no LVDS FHD 14" panels.

 

Not sure about this one, from the low viewing angles on the CES videos of the laptop, the viewing angles suggest that the Y40 is TN, whereas AW 14 is IPS. And 1920x1080 falls within 2048x1536.

 

Of course components have shrunk considerably since the 80s as transistor count/density has skyrocketed. The first Compaq Portable (aka "luggable") computer weighed 28 pounds, which is heavier than many desktop computers nowadays.

Many manufacturers use multiple suppliers to manage their manufacturing supply chains. However, I was surprised at just how drastic of a difference there was between the keyboards on two Y410P laptops. I would not have noticed this unit-to-unit variation in keyboards if I had not required a replacement laptop to be shipped by Lenovo. If you were not aware that you could not custom-configure the keyboard during the ordering process, I could have fooled you by showing you both laptops and telling you that I customized one laptop during the online ordering process to have a soft mushy keyboard with a dim backlight and the other laptop to have a firm keyboard with a bright backlight. Both laptops have AC power cords made by two different suppliers, Longwell and Linetek, but the only difference between both power cords is that one cord is a half-inch longer than the other cord and the different manufacturer's name is molded into the three-prong plug. These small differences between suppliers are totally expected.

Some people may not care how a keyboard, mouse, or touchpad looks and feels, but these tend to be highly personal preferences for most people, just as glossy and matte screens are personal preferences. If you ordered a Y410P with a glossy screen, but were shipped a matte screen that was not really glossy because it came from a different supplier, you would also wonder about that. And if you ordered two identical keyboards made by Logitech/Microsoft/Corsair/Razer/etc so that you could use one keyboard at home and the second same-model keyboard at the office, but one keyboard had soft mushy keys with dim backlight while the other keyboard had firm keys with bright backlight because the keyboard assemblies can from two different suppliers, you would think that was not good. Small variations of components between different suppliers are expected, but allowing for this much difference in key firmness and action, appearance, and backlight intensity between different suppliers is not good, IMO. The manufacturer should minimize the amount of variation both between different suppliers and between components made by the same supplier. Another example: what if you knew that Lenovo used three different suppliers for the TN display panels on the Y410P, and one supplier's panels had better color accuracy, black depth, contrast, and a wider gamut while the other two suppliers made lower-quality panels where the colors looked more washed out. If you did not receive a laptop that used the better supplier's display panel, even though your laptop had no defects, it would be tempting to exchange the laptop in order to try to get one with that better supplier's display panel.

 

I suppose i have the "white" keyboard and not the "pink" one, good feedback and keys are not overly mushy.

 

Looks like lenovo put the stock amount on the y410p. I'm guessing they're phasing it out for the Y40, I suppose. Hopefully they stay long enough until I pick one up.

 

Yeah. After installing Windows 7, I can use ShadowPlay and i think it's great because it doesn't decrease performance at all. Tested COD BO2 multiplayer.

 

Aside from FHD and thinness, the Y40 won't offer much. Rumor has it the GPU will be weaker, and it will only be .2lbs lighter. Also, the Y40 won't have the subwoofer either.

 

Was just wondering if anyone is having issues with the latest Nvidia drivers for the GT 755M?

 

Nope, then again i don't game as much on my laptop as much as i used to. However i am running latest and had no issues in Garry's Mod and APB:Reloaded. However i have a GDDR5 750M, which is an "underclocked" 755M, though i did the overclocking myself, so it's stronger than a stock 755M.

 

Agreed. If it really ends up being the GeForce 840m gpu that is.

 

Nope, R9 270M is confirmed as the GPU, but it's gonna be a rebrand of an existing GPU which is already 10% weaker than 755, and without the awesome overclocking power of kelper. 840M would have been a more logical choice, since the 840M is the 750M (and 660M).

I just want the Y40's screen to be LVDS so i can buy it and install it myself. Only 5 months of warranty left anyways

 

Got my replacement the other day.

So far so good. Trying to take it a little slower with removing bloatware and customization. Downloaded Steam and a few games, played Wolf Among Us for awhile, looks great. I did switch to "Always Use NVidia," so will see how that goes. Going to fire up Dishonored tonight and try to get some real gaming in.

Will post later about part differences - if any - but manufacture date was something like 2013/12/13.

 

Wait... How did you get ShadowPlay working on a 750m? I thought it only worked on GTX type cards.

 

"I can use ShadowPlay"
no offence, but i don't think its true
we all can launch ShadowPlay, but not use it.

 

It works on all cards as long as you don't have optimus, which means he has a Y510p w/SLI.

 

any solution for y410p users?

 

Hi guys. I know its repetitive but I searched the thread and there was no solution to my problem.
I have a Windows 8.1 Y410p that I got for Christmas.
I've been trying to get the webcam working but in the device manager; there is no imaging device. I attempted to reinstall the driver on the Lenovo Support website but I get an error saying that the driver installation is not appropriate.
Can anybody help? Thank you.

 

I can't say I have a solution, but I did have the same problem as you. It went away after a couple weeks for whatever reason. Maybe an update idk. Wish I had a better answer for yah =\

 

Sorry about second post but I'm still searching and got nothing. How can I find express cache drivers for Win8.1 ? I've been searching for long time but cannot find any. I assume it's already installed with Windows or what? I just want to use my SSD(24GB) as an express cache.

Plus, usually my SSD disappears like unplugged from the system or shutdown itself, why this is happening? Happened to anyone before?

 

ExpressCache Software for Windows 7 64bit, Windows 8 64bit - ThinkCentre, ThinkPad

 

How much undervolting is reccomended for the i7 4700mq?

 

-80mV seems to be the safe threshold, anything further requires manual stability testing.

 

Need a bit of help, I was going through and tuning up my machine and got to defragging and came upon this in the defragger. Can anyone tell me what this drive is? It says its 31% fragged. Is it the SSD? I tried to install perfectdisk and it threw up a error about that drive and wouldn't let me optimize my C:.

 

Ok ty, Is intel XTU good enough for stress testing?

 

i gave Shadowplay a shot yesterday and it worked!
i think it has something to do with the last update of GExperience.

tried it on BFBC2, CS:GO, Rising Storm and BF4
worked fine but didn't work on BF4 for some reason.

i'll upload some videos later.

 

Yes, but it cannot test your Nvidia GPU, only the Intel CPU/GPU/memory.

 

It will be fine, i just want to make sure that my cpu can run fine without any stability problems. What other programs do you reccomend for stress testing and monitering?

 

Prime 95/wPrime (CPU)
FurMark/Kombustor (GPU)
Looping a 3D Benchmark (Both)
Playing an Intensive Game (Both)

For monitoring:
- SpeedFan/HWinfo

Overclocking/Unvdervolting:
- Intel XTU (4700MQ and HD4600)
- MSI Afterburner/Evga Precision (GT 755M)

 

Nope, I can really record my gameplay using ShadowPlay. Btw, im using Y410p with single 750M and optimus


edit: i saw your post, which version of GFE you're using ?

 

yes u r right.
i used it as well
sorry for my post

 

this temps its good for my y410p ? i was playing Assassin's Creed IV on medium for 3hours.. my 750m hits 98 when i was playing oO its safe?

 

I would not say they are good temps, but they are still within the safe range.

 

My Shadowplay test :

my shadowplay is still greyed out

Something about not having a geforce gtx desktop gpu 600 series or higher.

 

have you opened the Shadowplay control panel ?
i posted a link in the description of the video about how to open it.

made an other video, hope u guys like it, and dont forget to comment for any question :thumbsup:

i'll try different sitting in the future.

 

I'm going to get the version with the Intel® Wireless-N 7260 to avoid network issues. Only problem is it comes with 62 watt battery vs. 72 watt. I've heard 62 watt max life is 5 hours and 72 watt is 6 hours. But that's max, so I'm assuming lowest brightness, ect. For normal brightness and standard web browsing what can I expect with a 62 watt battery? Thanks!

 

You must use the shortcut trick to open shadowplay control panel. After flipping the switch for first time, screen will flicker about 2-3 times.If it not flickering, then the recording does not work in-game.

 

Actually, that's what the normal is at 40% brightniss, implying you don't have too much of a load, as the CPU/GPU are the main power hogs in the laptop.

Also make sure Optimus is enabled (Auto Select) or you are on Integrated graphics, and disable bluetooth if you don't use it.

 

Thank you! That's great to hear. Looking forward to this laptop even more now!

 

That's pretty hot, but not meltdown hot. At those temps you're pretty much guaranteed to be throttling the CPU. Use XTU to reduce V core and reduce max turbo boost to x30 with 3 and 4 cores active. That'll lower CPU heat, which gives the GPU more headroom since they share the same heatsink. Also make sure all vents are unobscured. Try elevating the rear of the laptop a half inch.

 

how much i reduce in Dynamic CPU ? and Processor cache ? also i have a extra cooler 2500rpm under my y410p cost me 10 box.

 

What's the Y410p's battery life when web browsing and using MS word?

 

if you turn off the keyboard backlight and reduce the bright of the lcd to mid. It can be able to run more than three and a half hours.
