Lenovo Y50-70 UHD display - Gray dots on black background colour just appeared suddenly

Hi support technicians and assistants. 1 month ago 2 gray dots just appeared suddenly on my UHD display on the Lenovo Y50-70. Those can be seen only on black background. The dots are 3 mm long and 2 mm wide and the other one it's smaller. What can I do to fix those? They are very disturbing when I do something on black background! Thank you. If needed I can send pictures.

There are many gray pixels, visible on black background, in that 2 faulty areas because it is a UHD display. A 3 by 2 mm area means many pixels not only a few and there are 2 small areas like this one. I will try the recommandations and return a reply. Thank you.neokenchi wrote:
hi RomulusDaniel, From your description, it looks like you have a stuck pixel. Try to use a software like jscreenfix to fix it. Other methods requires you to put a pressure on the LCD screen (like in this wiki article). If you have a 3mm, 2mm, and a smaller dead pixel (total of 3), then I recommend you contact lenovo and report your findings.

Lenovo Y50-70 UHD WLAN grotten schlecht

Hallo, ich habe bereits das Forum nach Lösungen durchsucht, aber irgendwie komm ich hier auf keinen grünen Zweig. Ich habe den Lenovo Y50-70 UHD, SSHD 1 TB, 16 GB RAM. Wie man im Betreff lesen kann, habe ich Probleme mit dem WLAN Empfang. Standardmäßig ist in dieser Variante die Atheros Wireless kombination mit Bluetooth verbaut. Nach vielem rumlesen habe ich dann herausgefunden, dass da ungefähr jeder damit Probleme hat (ausser die, die 1m neben dem Router sitzen und sich nicht beschweren) und man Abhilfe schaffen kann, wenn man sich das Lenovo zertifizierte Intel AC 7260 o.Ä. stattdessen verbaut. Pustekuchen! Nichts hilft, diese habe ich verbaut und es bringt genauso die aller selbe schlechte Leistung, zudem kostet diese Karte natürlich auch noch.Ich muss vielleicht noch Beschreiben wie ich zu dieser Bewertung komme, dass die WLAN Funktion absolut "grotten schlecht" ist. In meinem Haus befinden sich 4 Laptops, 5 Smartphones (verschiedene Geräte, verschiedene Hersteller). Diese Geräte verwenden eben WLAN und arbeiten einwandfrei mit unserem Speedport LTE 2. Einwandfrei heißt, es sind 2 Stockwerke im Haus, es hat ein Ausmaß von 10 x 10 Meter und jedes dieser genannten Geräte (egal, ob gleichzeitig oder nicht) Funktioniert in jedem Winkel des Hauses (auch wenn z.b. 3 Wände und/oder eine Decke dazwischen sind) - abzüglich eines Laptops, dem neuen Y50-70. Das macht schon schlapp, wenn nur eine Dünne Wand innerhalb 5 Metern zwischen Router und Laptop ist.Schlapp im Sinne von Übertragungsratenmalus von ca 80% und Verbindungsabbrüche im ca. 10 min Takt. Laut Diagnose Tool ist eine Signalstärke von -50dBm an dieser Stelle:5m Entfernung mit ca 20 cm Dicker Ziegelsteinwand, angezeigter Empfang am Laptop, 4 von 5 Empfangsbalken (nicht besser oder schlechter als bei meinen anderen Geräten). Trotzdem Abbrüche und Übertragungsprobleme.Ich sollte noch erwähnen, dass es im Umkreis keine anderen Störenden WLAN Signale von Nachbarn o.Ä. gibt. Nicht nur, dass es Zuhause nicht funktioniert. Den Laptop habe ich gekauft um damit auch an der Hochschule arbeiten zu können, da ist aber schon allein das Problem, dass ich nicht mal Anmeldedaten eingeben kann. Es fragt mich nichtmal danach. Um diese Probleme zu Lösen, habe ich natürlich nicht nur probiert die selbstverständlich richtigen Treiber zu installieren(auch in bestimmten Reihenfolgen - Quelle Internet), sondern ich habe auch das vorinstallierte Windows 8.1 neu installiert, das funktionierte immer nocht nicht. Dann habe ich meine private win 8.1 pro version ebenso erfolgslos installiert und bin mittlerweile bei der neuen Win 10 Version angelangt, die mir immer noch keine Besserung bietet. Zu meiner Frage, da ich immer nur halbfertige Antworten in diesem Forum finde...Gibt es denn irgend eine Lösung, die den WLAN Empfang des Y50-70 verbessern könnte, oder nicht? Möglicherweise könnten Sie mir auch sagen, woran das liegen könnte, dass man scheinbar nur direkt auf einen Router verbinden kann und nicht auf Benutzerverwaltete Netzwerke. Ich danke im voraus und hoffe, Sie nehmen sich hierfür Zeit und können mir eine deutliche Antwort geben. Mit freundlichen Grüßen Edit: zur eindeutigen Identifizierung des Modells, die Herstellernummer: 59424196

Hey, ich habe genau das gleiche Problem und auch in meinem Thread konnte keiner helfen.Dass ich 900€ bezahle und der WLAN-Empfang bei scheinbar vielen Lappis dieser Reihe solche Probleme macht ist ein ganz großer Scherz. Von Lenovo-Seite bekommt man auch keine vernünftige Lösung bzw. Antwort und wird mit Reperaturen vertröstet die ebenfalls nichts bringen.Meiner geht definitiv zurück, das ist in der Preisklasse einfach nicht tragbar! Hoffe du findest noch eine Lösung, Beste Grüße

Lenovo Y50 4k UHD white color is really warm (yellowish)

Hi all,
I happen to have a Y50 FHD and a Y50 UHD placed side by side and I noticed the UHD produced dim and yellowish White color compared to FHD version. The panel on the UHD version is Samsung SDC4852.
I am not talking about the fiasco of "yellow being too dark" issue on previous Y50 version, although I know that this second gen Y50 UHD version that I got is SUPPOSEDLY fixed with yellow color issue.
This "warm white" color could be related to bad or insufficient back light but I don't know for sure. So anyone who owns a Lenovo Y50 UHD, please give me an input ?
Left : Y50 FHD
Right, Y50 UHD 4k
Brightness = max level on both screen
Power setting = High Performance

Is this forum a fan club or something ? Can atleast one of the moderator / support specialist comment once on any topic that hasn't got any replies ?
I spent the time taking pictures , making the post not to share my Lenovo stories. I want support. At least someone can confirm oh this is how it's supposed to be or , oh no , it is not ... Simple exchanges like that.

The primary Menu (File, Edit, etc) displays as dark gray letters on black background

Firefox 4.0 Beta 1 -The menu at the top of the screen displays in colors of dark gray on black. I was really thrown at first because I always display the top menu. But when I remembered how to display the menu it is very hard to see - it is dark gray lettering on a black background.
== This happened ==
Every time Firefox opened
== I installed Firefox 4 Beta 1

Reboot and see if your menu comes back.

[Desktop][Other] Gray scrollbar on black background

This is in regards to the Windows desktop app: Who thought it was a good a idea to have a gray scroll bar on a black background. You can barely see the thing. It's pretty ridiculous actually. Change the color to white

MacBook Pro display....problem with coloured pixels appearing

I wonder if anyone can help - I have recently noticed on the left hand side of my display on my MacBook Pro that there is a large number of coloured pixels appearing more and more by the day. I have had the MacBook since Christmas, and it has been treated very well, i have never dropped it or damaged it in any way etc. At the moment the pixels aren't causing too much of a problem but i don't want it to get any worse. Has anyone had similar problems, and if so any suggestions?
Many thanks in advance

I haven't had any luck what so ever - only thing left for me to try is to completely wipe the system and re-install everything from scratch, if that doesn't work then i think i'll be contacting Apple..... which i should have done already to be honest, would have saved a lot of time and hassle! Only difference between mine and what your describing on your Mac is that the pixels are visible at all times on mine, no matter what apps i'm running etc, it is definately a problem with the screen.....i'll keep you updated with any developments

How do I change the background color to black? I'd like Photoshop's generated web gallery to display photos against a black background.

I can't find a place to change the background to black from white. I'd like Photoshop's automated web gallery feature to show photos against a black background once I open the htm file inside Firefox. I use a Mac with OS 10.6.7 (current) on my 27-in. iMac. Thanks very much

There are often many ways to do things, and c.pfaffenbichler's suggestion above is good.
However, as I'm very fond of Curves, I'd use Image - Adjust - Curves (or Layer - New Adjustment Layer - Curves) myself, and pull the black point of the blue curve up.

Lenovo Y50-70 screen problem

Hello. Recently, i have bought the Lenovo Y50-70 laptop and it seems that there is some screen problem. I have a feeling that it does flicker sometimes (1-2 per hour, sometimes more). Firstly, I thought that the backlight changes for a second, but then, after more observation, it might be it turning off and on immediately, or the colours fade and return to normal. I can't say for sure, what it is, because it happens very quickly, but the eye catches it anyway and it is kind of annyoing. Moreover, once the screen went completely crazy, it started to turn off and on every 2-3 seconds, big portions of view weren't even displayed, and what wasn't displayed changed every time it turned off and on. There were also green and red dots moving all over, mouse was moving in slowmotion (like I were playing a game in 15 fps). Only the restart helped and it stopped. So the question is, what is wrong and what am I supposed to do? Sorry, if the english is bad, but it isn't my native language.

I live in South Africa. Bought the notebook on 14 July 2015, within 2 weeks I started experiencing the screen flickering and grey lines. I was told by Lenovo to roll back drivers, then update drivers etc. - nothing worked. I returned the laptop to the supplier who in turn sent it to Lenovo. Lenovo has offered to replace the unit. I am hesitant to accept another unit and am thinking of rather getting a refund so that I can buy an Acer Aspire V Nitro (same specs). My previous laptop was an Acer and did not give me a day's trouble. Don't bother trying to update drivers or open the screen to plug it into the motherboard etc. I think the issue is a power supply one and that Lenovo should do a recall of this product. I am just thankful that South Africa has consumer law which forces a supplier to replace, repair or refund a defective product within 6 months from purchase if the consumer wants - so they can't simply repair, if I want a refund, they must give me one. Good luck! PS: This was my first and last Lenovo product!

Photoshop CS6 Menus and Icons too small on Windows 8.1 with 4K UHD display

Hello,
So I have seen that I am not the first one to ask this question, but I have yet to find any true resolutions. I recently bought anew laptop, a Lenovo with a 4K UHD display which I already love for so many things. But, like a few other programs, the high resolution means the icons and menu text of PS CS6 are incredibly small, which may be alright on a TV, but on a laptop screen, it make it incredibly difficult to work. I have tried all sorts of different approaches in Windows, such as changing the OS font sizes and icon sizes, which do indeed change everything else on the computer, but PS is still the same tiny size. I have also increased the text size under the interface preferences to large, but with little real change. I understand why this is happening, but I am hoping that there is some sort of workaround, beyond just bumping down my screen resolution, which defeats the whole purpose of using UHD to edit photos. I have heard rumors of being able to code in some UI changes manually, but have found no concrete examples of how to actually do that.
I am sure that it would not take Adobe too much time and effort to create an update to help with scaling, but they are very set on pushing forward with Creative Clound, leaving the rest of us loyal customers to the dust until we pay up. If anyone has found any resolutions or workarounds, I'd really appreciate it. Thank you.

Well other than that, I can't offer anything else as a forum volunteer. I have no idea if anything, what Adobe plans to do for CS6.
I do know that Photoshop CC 2014 has a 200% ui feature for Windows and you might like the Photography Plan which for $10 monthly includes Photoshop CC 2014 and Lightroom for $10/month.
You can trial CC 2014 to see if it does solve your situation

IPod shuffle problem; little gray dot?

Hey there.
Whenever I put my iPod shuffle into the usb port on the back of my laptop, the iPod is displayed, etc ... But I can't take songs on or off anymore. I deleted them, and they don't show up as on, but when I turn the shuffle on, the same songs are on. When I add a song, I get a little gray dot next to the songs, and they are not added.
Please, some help with this ...
Oh, and I have the latest updater and the latest of iTunes installed.

Read these articles:

This will explain the symbols used iTunes - what you describe is an item not yet synced on your iPod.

Help Lenovo Y50-70 Win 8.1 clean install

I'm new to Lenovo, Win 8 and to this forum. I'm considering buying Lenovo Y50-70 Notebook model 59441814 - Intel Core i7 4270HQ, 8GB DDR3L, 256GB SSD, NVIDIA GTX 860M 4GB, 15.6" Touchscreen, 4K UHD, USB 3.0, no DVD drive and Win 8.1 pre-installed. I also have retail MS Win 8.1 Pro "Full Version" 64 bit DVD and key. Would like to upon receipt of latptop to: (1) replace 256GB SSD with a Crucial MX200 500GB SATA 6Gb/s 2.5" SSD, and (2) do a complete clean install using my retail 8.1. Reasons are: increased capacity and get rid of all the unnecessary stuff that Lenovo pre-installs. Since I don't have a DVD drive and I have read there are some issues with boot secure, can someone provide recommendation on sequence of steps to follow. and /or how to.
Solved!
Go to Solution.

hi Forest1,
Welcome to the Forums.
When you receive the Y50-70, can you try these steps:
1. Follow this video disassembly guide on how to replace the HDD with an SSD. Alternatively, you can also watch this youtube video on how to replace the drive.
2. If you're planning to install Windows 8.1 Pro in UEFI mode, follow this guide on how to convert the DVD installer into a USB installer. When finished, boot into the BIOS and set the following settings then hit F10 to save and exit.
- Link to picture
Secure Boot = Disabled
USB Boot = Enabled
OS Optimized Defaults = Other OS
When finished, boot from the USB flashdrive that you created (by tapping F12 and selecting the flashdrive on the boot manager) and you should be able to install Windows 8.1 Pro on the SSD.

If Lenovo or MIcrosoft can provide an update to the driver it may work. This might be ongoing with Microsoft or Lenovo. Why not install the optional windows update KB3035583 so that you will see if your unit will qualify later if the taskbar icon will show up (if you hover over it, it will show "Get Windows 10").

Lenovo Y50 still have the hinge breaking problem?

Do anyone know if the Lenovo Y50 is still having the screen display hinge breaking or exploding from the base problem?

My Laptop has just started falling apart about a month after my warranty ended (of course) here is my list of problems that have been happening since my warrenty ended. 1. The part that the screw actually screws into the part that holds the hinge to the laptop has broken off so my screen is being held on by 1 screw very scary as it could fall of any minute. 2. The plastic piece that covers the hinge will pop off everytime I open my laptop and makes a horrible cracking sound when I have to keep opening my laptop to snap back the plastic piece so that I can use my laptop. I am now using scotch tape to fix this for now very embarrasing when gaming with my friends. 3. I have been slowly losing screws on the bottom of my laptop to hold the whole thing togeather I am now down to 8 out of the 12 that are supposed to be there. A screw just recently fell off and it happend to be the last screw that was holding my screen to the laptop so I had to swap some screws around so that my screen was being held on by something. I was looking for a quality gaming laptop I could take to college and I will be heading off to college in a month! I would not sugguest this laptop and will probably never purchase a lenovo product again as this seems to be a somewhat common problem.

Lenovo Y50 Microphone Issue

I started using my Lenovo Y50 about a month ago and have been having an ongoing problem with external microphones/headsets.The issue is that when I plug in a headset, the sound defaults to the headset's speakers, but the default microphone remains the one in my laptop. I have not been using a USB or the S/PDIF plug; just the normal audio jack. So far I have tried three pairs of headphones: A TekNmotion Yapster Blaster headset, a pair of apple earbuds with the mic attached, and finally a Razer Kraken Pro headset. Based on that, I don't think it is the fault of the headsets.Additionally, my brother got the same exact laptop at the same time, and he is experiencing this issue as well.We figured out a temporary fix:Open the sound menu, go to the "Recording" tab. For us, there are three items present: "Line In" for the Razer pro headset, "Microphone," which I assume refers to the laptop's mic, and "Stereo Mix." By setting the default device to "Microphone," then unplugging and plugging the headset back in. It will now work, but only when the "Sound" window is open. As soon as the window closes it stops working. I have tried splitting the speakers and mic, plugging in just the mic by itself, but it will only work with a combined jack. I have limited knowledge of the S/PDIF input, but from my troubleshooting experience I found that it does not work with the split mic or speakers, or combined audio jack. (I have no idea if this is relevant) Here's everything:ProcessorIntel(R) Core(TM) i7-4720HQ CPU @ 2.60GHzManufacturerIntelSpeed2.6 GHzNumber of Cores8CPU ID Family06Model3CStepping3Revision Video Card 1Intel(R) HD Graphics 4600ManufacturerIntelChipsetIntel(R) HD Graphics 4600Dedicated Memory0 BTotal Memory1.8 GBPixel Shader Version5.0Vertex Shader Version5.0Hardware T & LYesVendor ID Device ID Plug and Play ID Driver Version10.18.14.4029Video Card 2NVIDIA GeForce GTX 860MManufacturerNVIDIAChipsetGeForce GTX 860MDedicated Memory4.1 GBTotal Memory4.0 GBPixel Shader Version5.0Vertex Shader Version5.0Hardware T & LYesVendor ID Device ID Plug and Play ID Driver Version9.18.13.3250Memory16 GBOperating SystemMicrosoft Windows 8 (build 9200), 64-bitService Pack0Size64 BitEditionBasicVersion6.2.9200Locale0409BIOS9ECN37WW(V2.01)VersionLENOVO 9ECN37WW(V2.01)ManufacturerLENOVODate Sound Device 1Realtek High Definition AudioDriver Version6.0.1.7195Sound Device 2NVIDIA Virtual Audio Device (Wave Extensible) (WDM)Driver Version Sound Device 3Razer Surround Audio ControllerDriver Version Thanks for any help provided.
