Q: Lenovo Y50 Update Issue

I have a Lenovo y50. Just now i was trying to update my bios but during the process my system was stuck. Its been in this state for about an hour and i dont know what to do. kindly help me with this issue. I have uploaded the picture of the state in which my screen is stuck right now.

Preferred Solution: Lenovo Y50 Update Issue

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Lenovo Y50 Update Issue

Contact Lenovo. If you power it down, you can end up with a dead laptop.

Hi All, I have received my Lenovo E480 yesterday and been having two issues :  1) I can't update the BIOS to ver 1.15. The laptop reboots after running the setup but BIOS upgrade doesn't happen and I get the Windows login screen. 2) Whenever I shutdown the laptop, it restarts. Only way to shut it down is by long pressing the power button. Can you guys please help on this. Thanks

Starting this morning, my Lenovo Yoga 910 IKB appears to go through a system update . It has been going on for quite some time, the update takes up to 30% of the CPU and my battery life has decreased substantially. In addition, it says that it is a Lenovo System Update(32 bit), while I know that my system runs on 64 bit. My questions are:1. How long should a system update take?2. Is it normal that the system update is 32 bit?3. If it is not normal, how do I stop the system update and how do I run a 64 bit one?Thank you!

Hello, Lenovo team Can you please, add to your next BIOS update for Lenovo Y50-70 a fix, that my laptop won't lose CPU speed after i return my laptop from sleep mode. Right now i'm using BIOS version (3.03) There is no other way to fix this issue, only you can do it with a BIOS update for that model of laptop. Thank you.

The computer I used was '' Lenovo Y510P ''. There is a '' Nvidia GT755M [SLI] '' as a display card. I have tried both ways of downloading the video card driver from both GeForce Experience and Nvidia driver site. Both kinds of graphics cards are starting to update. Later, the 'graphic driver is installed' part of the screen goes and never comes again. I can not enter Windows when I turn off the computer. I have to take format from scratch.After formatting, Windows automatically loads a graphics card driver in 2017, trying to update the driver again, it stays black on the screen again. I have to format again.With DDU (Display Driver Uninstaller) program, I deleted the old video card driver and updated it again. But I met the same problem.I communicated with Nvidia and stated that I had such a problem. They asked me not to install the 388.13 video card driver. That graphics card driver has been loaded without any problems. But I have the same problem with all the video card drivers out there.NOTE: This problem only happens on Windows 10. I can update the display board without any problems in operating systems like Windows 8,8.1.NOTE: I have been having this problem for about 2 months, before I could update my display card in Windows 10 without a problem.The driver I am currently using is: 388.13

Hello, For more than a year now, I have been using my Lenovo laptop without any problems (Model: 500-15ACZ Laptop (ideapad) Serial Number MP10L224 Machine Type Model 80K4001MUS with Windows 10-64Bits.) About 2 days ago, Windows 10 pushed an update. Since then, I have the following problem: whenever I boot the machine, it works fine for a couple of minutes and then, while working, the screen unexpectedly turns blank and the computer restarts without any warning. After restarting, the machine works fine for the rest of the day. This has already happened 2 times and, needless to say, it is worrysome to have a computer that can crash at any minute unexpectedly. Have any one been experiencing the same problem with this latest Windows 10 update? Would anyone have a solution? Thanks,BFonseca

A:Lenovo Ideapad 500-15ACZ restart issue - Windows 10 Dec. 2017 update

Is there anything reported in the Windows Even Logs when that happens?    Also check the C:\Windows folder for any recent MEMORY.DMP files that would indicate Widows is crashing (BSOD), and check for any updated drivers via Lenovo Companion, or manually from https://support.lenovo.com/us/en/.

Spoiler (Highlight to read)IMPORTANT!!IMPORTANT!!Friends from Lenovo,Yesterday I did the update to the new version of Windows 10, called Windows 10 Fall Creators Update or Windows 10, version 1709, and after the update was done I find out that the hotkey driver, that controls the Fn commands on the keyboard of my Lenovo ThinkPad X220, doesn`t work correctly with this new version of Windows 10. Therefore, I would like to know what can I do to fix this issue, so the hotkey commands work properly again in my notebook, or if it is going to be an update of this file (8jvu43ww.exe) that I could install in my notebook to fix this issue. Could you please tell me what can I do to make the Fn commands work properly with the new update of Windows 10 (Windows 10 Fall Creators Update) or if it is going to be an update of the hotkeys that is compatible with the new version of Windows 10?I look forward to hear your comments, and I hope you already have an idea, an answer to solve this issue. Yours truly,Cristián Palau

I've been getting the "Thread Stuck in Driver" BSOD when playing games for several months now and have just been trying to ignore it. However, it's gotten too bad to be ignored any longer.

What is happening with Lenovo System Update? We are getting an error that the package catalog is being updated? We have several models here and its happening on all of them.

I posted the same on their tech support forum but I'm beginning to think the issue, while it may have been exacerbated by the game Guildwars 2, is likely on my end, but I have a number of suggestions, none of which has worked. Also tried my own stuff.
Anyway, here is what I posted on their own tech forum:
Having a lot of issues getting into gw2…I have bits and pieces of problems others have had in the past, but nothing seems to work, so I’m re-downloading the game, basically. All I want to do is play the freaking game, why does it have to be so much trouble?
Once in awhile I will get that blue and yellow graphical glitch on something. Just more info for diagnosis. If and when this happens, it’s always immediately apparent at character select. However…The biggest problem I have with GW2 is also on login – it either crashes or bluescreens my computer right after clicking play and the client tries to load for 5-10 seconds. For the past few days, 90% of the time it just crashes. If I try to patch after that point, the patcher stops at Downloading 0KB and will not budge from it. Not even to log in. I have to reboot my computer to get it past “Downloading 0KB”.
One post I found said that they started having all these problems after downloading a number of games on Steam (which I have done off and on due to a friend getting me a few gifts) , until their HD shrank down to 30 gigs. Same here, an... Read more

A:Odd memory issue? HD space issue? Also, can't update GPU driver (GW2 crashing)

Unfortunately, though I thought I did, I have no images of the odd cyan/yellow graphics glitch, and I have no way of getting one (google didn't turn up any that looked the same as mine, granted some were similar).
Edit - I also noticed after re-enabling page memory on my primary drive after freeing up some space, that in the error logs, the amount of paged memory in use is for some reason higher. I can't imagine why this is, but maybe I don't understand the process.

Window 7 x64 pc with Avast virus
Notice the issue yesterday, not sure how long it might have been affecting Firefox.
Yesterday, Avast could no longer access server to update.  Went to Avast website to manually download virus file.  Said it was up to date.  After two days, I highly doubt it is still upto date.  Tried downloading a fresh copy of the software and reinstalling.  No change.
Now I just noticed Firefox also can not access anything and when I try to update it, it says it is up to date.  I have version 22.00, not the current 23.  Don't know how long it has been blocked from updating.  Didn't find anything to improve the problem in thier troubled shooting area.  Tried downloading new copy of Firefox..... and download failed.
Two days ago, I downloaded a Windows update, classified as Critical.
I do have another computer running on the same internet connection.  It appears to be fine and has to current Firefox version.
Is this a virus or a result of the Window's update?
Thanks for your help!

A:Avast and Firefox update blocked, virus or Window Update issue?

I forgot to say, Internet Explorer and other programs are working just fine.  No issues accessing anything on the internet.  The only problems,  appear to be Firefox and Avast unable to connect to server.
Hope everyone has a great weekend!

Hello, I have Carbon X1 5th (20HR) running Windows 10 pro (updated).  Altought I followed the instructions here - https://pcsupport.lenovo.com/cy/en/downloads/ds120390 (This is the page for Lenovo users who wish to update TPM firmware) - and installed the "BIOS Update Utility for Windows 10" version 1.33, Windows still keeps telling me to update the TPM firmware driver.  In BIOS it shows that I have TPM ver 2.0, enabled. Since Windows kept telling me to update the TPM driver, thanks to Google I found out that there is a tool created by Lenovo called "TPM Firmware Update Utility -ThinkPad" (It is worth noting that this tool is not mentioned on the instruction page). I downloaded the tool, but can't understnad how to use it (assuming that I should use it at all, because this tool is not mentioned on the TPM instructions page). Could you please help me to solve the TPM issue described above? Is there a way to check what version do I have? Thanks in advance!

Since you have to hunt around different Lenovo sites (and other sites) to find out about these softwares, I decided to make a post to get feedback from actual Yoga owners on how these programs interact, what they do, which ones are prerequisite, and which ones are unnecessary. Please don't take this as a blanket answer. This is just what I have found. It might be right - it might be wrong. I'm looking for others to post their experiences as well. Lenovo System Interface Foundation Driver - Necessary prerequisite (missing driver in device manager without it). It allows the Lenovo Utility and Lenovo Companion to work. Lenovo Yoga Mode Control - Necessary if you want to use your yoga to seemlessly change between all the different modes (laptop, tablet, tent, stand). This software is responsible for autorotating and putting Windows into tablet mode. Lenovo Utility - Recommended(?) This one I'm not too sure on. I remember that I was missing some function that I wanted but I can't remember what it was now. Maybe battery cycle count and health? Lenovo Companion - I don't have this one installed and don't think it's necessary but would like someone else to shed some light here.

Hi, I have recently just got done building my computer. Did the hardware, pretty much all the software till all I had to do was install 231 important windows updates. So I aloud it and it took a good hr to install it all.. than the computer shuts down and I turn it back on, than it goes into configure the updates mode.. 20 minutes later it says failed windows updates and is now reverting back.. and not in those exact words.

When I was finally able to get out of the revert update screen which took about 30-40 minutes everything seemed normal, till I opened the update history screen and showed about 95% of the updates failed. I also noticed that it had installed the updates on my HDD which is my D: storage but should have installed it on my C: SSD storage. Now I need to figure out how to get rid of that locked folder on my HDD and place all the windows updates on my SSD.


i7 4790k cpu

gtx 750 ti gpu

ddr5 2400 memory

evga 850 g2 psu

Z97 gaming 5 mobo

Samsung 500gb SSD

1.5tb HDD (seagate I think)

windows 7 64bit home

I've been searching around to see if there was a fix but a lot of people have had a really hard time with this issue and seems to be so many people unable to fix it.. I'll be turning off windows update till I figure this out.

I find myself pretty good with computers but my laptop is having an issue that I've never seen, had, or heard of before. And it's something I couldn't find a solution for online at allI own a Lenovo Y50-70 (2016, specs at bottoms) I bought it refurbished with a 1 year warranty almost a year ago on the dot. Saturday night it bassicly ate the dustWhen I power the laptop on, the keyboard light starts up, the power and low battery light work. But nothing else. The fans don't start working either until about 20 seconds after pressing the power. USB items (my mechanical keyboard and mouse) don't receive any power. I tested with an external monitor to see if the display was dead and it didn't even post to the monitor I tried disconnecting the battery and nothing changed with it plugged in, I did a 10second reset with no battery. I have tried checking the fans and making sure nothing came unplugged under the hood and couldn't find anything wrong Another thing, when I unplug it it makes this awful beep noise (single)If anyone has a suggestion or a known fix PLEASE tell me, I'm a high school student that just spent all their savings on a car which I still need to register.

It only reaches 92 percent and light goes green and will not go further no matter if i leave it plugged in. I seem to be getting good hours on a charge but worry that unit is defective. Any help...Thx

Hey everyone, Recently, my Lenovo Y50-70 started acting up. All of a sudden, i could not connect to a WiFi network. Whenver i check devicemanager, i see this "other devices -> networkcontroller" which has a yellow triangle with an exclamation point in it. So i figured... this must be the problem.  Now whenever i check properties on this device, i get alot of stuff that i dont even know what it means. But the path directory to this device should be (it says this in the properties) ..\Driver\ACPI.  I dont really know what to do now... should i just delete this device and reinstall? because i could not find any ACPI drivers for my device. If anyone could help me out, that'd be great. Since i can not stay connected to this ethernet cable for ever.I will respond to any messages, so if anyone tries to help me, we can find whats up. Thanks,Yves

A:Lenovo Z50-70 bluetooth issue

hi MarieNville,
Welcome to the Forums.
Can you please try the following:
1. Navigate to Control Panel (icon views) > Programs and Features and remove any apps that relates to Bluetooth (reboot if necessary).
2. When finished, the Bluetooth section will now use the inbox Bluetooth Driver as shown in the image below:

3. If the Bluetooth section is not present, download and run the Bluetooth Driver installer
     - this will identify the type of Bluetooth Device installed on the system (eg. Qualcom Atheros, Intel, etc.) and it will install a generic Bluetooth driver. If successful, try pairing a bluetooth device and observe.
If everything goes well, try installing the official bluetooth drivers by navigating to the D:\Drivers\Bluetooth folder or from the Z50-70 drivers page and observe.
Let me know how it goes.

Hi! I have a G510 laptop. Few days back the LAN stopped working. It does not detect the ethernet connection....It says 'unidentified network'. I tried a system recovery, did a full antivirus scan but the problem still persists. Please help me out...I'm really worried!

A:Lenovo G510 LAN issue

Hi Saum , 
Welcome to the Community Forums.
How did you do system recovery ? 
Was is just a system restore or a full factory system recovery using the novo button from initial back up ?
Was there any yellow marks on device manager ?
Any blinking link lights on the port connection of the cable when plugged in?
Update us so we can further isolate the issue.

Hey Lenovo, I recently bought a G51-35 and noticed a problem with posterization, otherwise known as color banding or the absence of dithering. My googlefu has come up with various ideas on fixing the issue, such as updating the Radeon R5 drivers, recalibrating the display, and using the Lenovo Settings to tweak the color settings -- all to no avail.  I began to think it was a problem with the screen being unable to produce 32bit colors, so I hooked it up to an external monitor that does show 32bit. The problem persists over to the other screen, so I don't believe it to be the laptop screen. Another thread from last year on this forum said the solution was to adjust the angle of the monitor, but in practice, this doesn't fix the problem; if anything, it worsens it. This narrows it down to the BIOS configuration or driver issues.  At this point, I can't think of anything else to try and resolve the issue. Any ideas? Because of the posterization, I can't reliably use the computer for any form of graphic design, which is part of the reason I bought it. My gut is telling me that dithering is disabled somewhere in the BIOS config, but I have no idea how to enable it. Any insight into checking this would be nice. Any help would be appreciated, thanks! EDIT: Not sure why this posted in the wrong forum, might need moved by a moderator.
