Please help. Lenovo Software or driver problem

I am having a problem with my Haswell Levono Ideapad Yoga 11S. Anytime the computer "updates" in any way, my SDCard slot, Both USB ports and the Touchscreen stop working. I originally thought it was a windows update issue causing it, but its not. I disabled all windows updates and it has not done one. I thought that fixed the issue, but then I uninstalled a software that required a reboot, and the issue started again. Each time this happens I have to do a restore point back to a restore point I made on 5/22/2015 in order to get it working, so I know its a software or driver issue. Pretty sure its some of this Lenovo software cauding the issue, or a Lenovo driver. I get two messages that pop-up in lenovo style pop -ups. #10engineinitializationfailed and also #10Motioncontrolerror or something when this happens. Also something pops up in my Device Manager as "unknown" but there is no way to tell what it is. Can someone please help me? My last post on here died without any comments at all. It seems like Lenovo just will not help me with their product they sold me. Am I just out of luck? Do I need to stop buying Lenovo products? I dont know... It seems so. Lenovo, answer me.

It looks like Windows Update tries to update a wrong driver and fails ? The update is probably an optional one, because most of the drivers updates are.You know you don't have to accept all the optional updates. You can even tell Windows not to show them anymore: right-click on the update, and choose not to show it anymore.

Lenovo g510 amd driver problem

my new lenovo g510 reads the amd vga as r5 m230 instead of 8570 altthough i installed the driver from the official cd ?? is that a problem or okay ?

Hi Zoomin,
Welcome to Lenovo Community!
I’m glad to inform you that as the driver is installed and working as expected this confirms that driver is for the exact mentioned AMD Hardware and there is no need to worry.
Do post us back for further queries.

I also updated audio drivers but nothing changed so kindly help me plzzzzzz.......

hi,
In the photo you posted it looks like the Audio is running as Highdefinition audio, meaning it has no driver yet
Please try installing the driver first and try the audio jack again

Lenovo T400 screen goes dark issue, some video driver problem

Lenovo:
Motherboard:
CPU Type: Mobile DualCore Intel Core 2 Duo P8600, 2400 MHz (9 x 267)
Motherboard Chipset: Intel Cantiga GM45
System Memory: 1992 MB (DDR3 SDRAM)
BIOS Type: Phoenix (08/19/08)
Display:
Video Adapter: Mobile Intel(R) 4 Series Express Chipset Family
Video Adapter: Mobile Intel(R) 4 Series Express Chipset Family
3D Accelerator: ATI Mobility Radeon HD 3470
Problem/Issue:
Driver problem appeard after upgrading from XP to Windows 7.
From the Device Manager I saw that ATI Mobility Radeon HD 3470 was not working properly and
a) I did the "update driver software." After restart the screen light was darker than usual. (This was usual if I was working from battery but I was plugged in this time. )
As I'm not the best with computers I thought my drivers might be in conflict and to prevent serious damages, I just
b) disabled ATI Mobility Radeon HD 3470 from device manager.
This actually resolved the dark screen problem.
c) then I went to Lenovo support site: http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?&LegacyDocID=MIGR-72858
downloaded newest drivers for ATI Mobility Radeon HD 3400 (Switchable Graphics Driver)
and Intel 4500MHD (Intel GM45 Express Chip)
For some reason while installine the: Intel GM45 Display Driver (version 8.15.10.2302) gives me error:
"This Computer Does not meet the minimum requirements for installing the software"
Also some problem appeard when installing the new downloaded version:
ThinkPad Switchable Graphics Driver (version 8.792.5-110424b-119200C)
d) so I went back to device manager and made an update to ATI Mobility Radeon from there.
Well, I got it working, but the screen went dark again. When I disable the driver it goes back to normal
brightness and when I enable it again, it stays normal.
I'll try to restart and see what happens

We had the excat same issue.
I could get the picuture back pressing the power button until it went to sleep and then wake it up again.
After the I went to device manager to delete all display drivers both Intel and ATI and then reboot.
doing the reboot windows found some drivers it could use.
I then installed the switchable driver from lenovo.
Now windows device manger report two display drivers:
1)
ATI Mobility Radeon HD 3400 Series, Version 8.792.5.2000, Driver manufacturer ATI Technologies Inc
2)
Mobile Intel(R) 4 Series Express Chipset Family, Version, Version 8.792.5.2000, Driver manufacturer ATI Technologies Inc
So it seams the switchable ATI driver take over the Intel card and the Intel driver is not needed.
At least the problem is solved for us.

Lenovo Drivers Insufficient for update to 8.1 - Driver problem - H430

Lenovo Drivers Insufficient for update to 8.1 - Driver problem (USB?) - H430
my lenovo H430 is about 6 months old - worked okay with preinstalled Windows 8
After update to Windows 8.1 computer no longer seemed to work well at all, although I am unable to provide hard evidence, but clearly it was not working as smoothly as in the previous 8 version with lots of irritating little problems - including sound.
One thing that very clearly was not functioning as it had in 8 version was the USB disconnect icon. In 8 you only had to click on icon and the USB selection window would open immediately. Additionally all USB connections would be shown - back and front USB. Select the USB to be disconnected and it would be disconnected immediately (providing not in use). After update to 8.1 this was no longer the case.
In 8.1 disconnect icon no longer worked as it had done in 8. After clicking on icon there was now always a lengthy pause, followed by the sound of the computer working (whirring sound) and then after a while the USB selection window would finally open. Sometimes it was necessary to click on icon a few times to get any reaction at all. A small MP3 player I had charged up on my computer every morning (front USB) in windows 8, was always in USB list, and disconnected without problem in 8. In 8.1 it was no longer in list and only charged sporadically (would stop charging, but if I clicked on USB icon it would start charging again - although still not shown in USB list).
After about two weeks of 8.1 my screen suddenly - but only briefly - went black twice. I ran a sfc /scannow. problems were found but could not be resolved. I did a Dism /Online/Clean-Image/RestoreHealth this was reported as being successful. About two days later my computer went into blue screen BSOD - "critical-services-failure" - from which I was unable to get out of. The only option open was the Lenovo restore option. Computer was returned to factory state with los of all data.
back to Windows 8 the computer once again worked okay - no problems - and USB icon once again worked correctly (including with MP3 player).
About 2 weeks later after receiving MS messages to update to 8.1 I called Lenovo support and asked about update to drivers for 8.1.
the following list was given:
Chipset: Intel chipset Driver for Windows 8.1 (64-bit) Version : 9.4.0.1022
Video: CPP2 AMD DISCRETE VGA CARD DRIVER for Windows 8.1 (64-bit) Version: 13.152
Audio: Realtek Audio Driver for Windows 8.1 (64-bit) Version: 6.0.1.7030
LAN: Realtek Lan Driver for Windows 8.1 (64-bit) Version: 8.018.0621.2013
STORAGE: Intel RST Driver for Windows 8.1 (64-bit) - Desktop Version: 12.8.0.1016
I updated to 8.1 and then updated all the above drivers (no USB driver update was available).
The same problems as the last update to 8.1 and USB was as bad as it was in last 8.1
Some days later my computer went into blue screen BSOD once again - although this time did not stay stuck there, and quickly restarted - due to speed of restart I did not get time to read all the text and discover the cause of BSOD.
Computer is still running badly - particularly the USB icon disconnect.
Called Lenovo support but they have been no help!!!!!!!!!!!!!!
Lenovo are failing us with the 8.1 update and the DRIVERS FOR 8.1
BSOD
all i could find was this: (probably refers to after BSOD - the restarting part after BSOD???)

I have now seen the suggestion by Tomaspoko and Brillow at http://forums.lenovo.com/t5/ThinkPad-Edge-S-series/Windows-8-1-update-S440-ThinkPad-black-screen-wit...
Despite the AMD driver giving an error during install at the last stage of the suggested fix, this has now yielded a working switchable graphics for my S540 for the first time with Windows 8.1. Catalyst Control Center also works for the first time, so thank you to both the above-mentioned posters for a solution that does work.
Hopefully in time AMD will release a non-broken updated AMD driver and CCC package.
Thanks again for a nice solution from this forum - the problem was driving me nuts!

Problema al iniciar Lenovo B50-30 Checking media...

Hola!
Hace tiempo que tengo este Lenovo B50-30 (80ES) que me venía con Windows 8. Lo pasé a Windows 7 de 32bits, lo cual tuve que volver a cambiarlo por el de 64 bits esta mañana. El error viene cuando después de pasarlo al formato de 64 bits que era el indicado, al terminar el formateo todo normal, el fallo comenzó cuando empecé a instalar los Controladores, al intentar instalar "BIOS Update Utility exe" (O al menos pienso que este pudo ser el último que intenté instalar antes del fallo) La cuestión es que la aplicación me pedía que no utilizara la batería para ejecutarla y que conectase el cargador. Hecho esto, comenzó a instalarse hasta que me apareció una pantalla negra con unas letras en rojo, tras cargarse por completo, lo siguiente que apareció fué:
El logo de Lenovo y después una pantalla negra que dice"Checking Media..." Tras esto, una ventana azul que dice:
"Default Boot Device Missing or Boot Failed.
Insert recovery media and hit any key
then select "boot manager" to choose a new boot device or to boot recovery media"
Seguido de la opción [OK], al presionar me lleva a un página de fondo blanco que pone "BOOT MANAGER" debajo; Boot option Menu y solo a poder elegir una opción: "EFI PXE NETWORK", pulso Select y: de nuevo "Checking media..." Solo que ahora en una ventanita azul dice:
"EFI network 0 for IPv4 (F0-76-1C-19-33-D5) boot failed, Y después este mensaje se repite si sigo presionando [OK]
Llegué a deducir por lo de IPv4 que necesitaría conexión a internet, por lo que cunecté el cable al ordenador y esto solo cambió la respuesta del cuadro, supongo que dando otro fallo, pero ninguna otra opción que no sean las que ya he dicho.
La cuestión segun he leido parece fácil de solucionar, pero mi verdadero problema recae en que no puedo acceder a la BIOS de ninguna de las maneras. Mi portatil no tiene ese botón para acceder a la BIOS, supongo que hay que hacerlo mediante F12, aunque los he probado todos, y al salir el Logotipo de Lenovo intento acceder a la BIOS y no me deja.
No sabría deciros si instalé el controlador de la Bios, si era el controlador propio de la Bios el que me ha dado este fallo, no sé. No estan todos los Drivers instalados, ya que este era de los 3 primero que me descargué por orden de la página y me salió el fallo este que no me deja acceder a Windows.
La verdad es que estoy un poco desquiciado con este error, asique agradecería muchiiisimo una ayudita. Y aunque no se supiera solución, otra duda es que si podría Re-formatearlo para solucionar el problema. La cuestión es esa, que no puedo Acceder a la BIOS y no se siquiera si lo podré formatear.
Gracias de antemano por dedicarme unos minutillos
¡Resuelto!
Ir a solución.

Para el caso 2 en el que que modificas la BIOS a legacy el disco duro aparece para el orden de arranque, con esta configuración Windows no carga normalmente verdad? mismo mensaje mostrador desde un inicio, recomendable en la pestaña exit verificar que en las preferencias de sistema operativo, este para Windows 7 en el caso de no estar este parámetro colocar en otros.
Si con esto persiste el mensaje problema, intenta arrancar el instalador de Windows 7 y verificar si el disco duro, para intentar verificar si es que el problema es debido a error en el arranque de Windows o de plano no tienes ningún sistema en disco que arrancar.
Un saludo.

Windows 7 install on Lenovo B50-30

Hello Everyone,
I suggested to a school that they invest in some Lenovo B50-30s as they were cheap and cheerful and would do what they needed.
I checked the Lenovo driver site and saw that there were windows 7 64bit drivers available, so presumed I would be able to downgrade them to fit their domain setup.
I have tried every different bios configuration, even taken the HDD out and installed win 7 64bit and checked it booted in another system and it was fine, put it back in the Lenovo and it just gets to the point where the Win 7 dots appear as they create the windows boot picture, then it blue screens and says the bios in this system is not fully acpi compatible.....which is what it says when trying to reload from every kind of media known to man.
Is there a genius out there who can save me many more pain staking hours of grief and tell me what to do please, the bios in this system is so basic its unreal, you can choose boot device priority and achi/ide/compatability modes etc, but thats about it.....what happened to ram voltage settings etc that I used to enjoy messing about with.
If anyone can figure this, I will buy you a pint!! I'm hoping in the words of Barney Stinson....."Challenge accepted!!"
Thank you in advance.
Andy

Hello,
Sorry for my english, i'm french.
I have the same problem.
I use a CD of windows 8 to delete all system partition.
After ther is no soucy to install windows 7
I hope it can help you

Lenovo M92P 2992E5U Monitor problem

Just recently bought a Lenovo M92P 2992EU from amazon.
http://www.amazon.com/Lenovo-2992E5U-M92p-Desktop/dp/B00A2V3SV0/ref=sr_1_4?ie=UTF8&qid=1375841434&sr...
When i plug my monitor to the motherboard VGA port, there's no display on the monitor. However, when i plug my monitor into the Video card's VGA port, there's display.
What's wrong with it? This is my second lenovo with the same problem. I didnt do anything to it. It is my first day using it. Also, i called Lenovo Tech Support, they remotely helped me do all of the driver update....

You must enable multi-monitor support if you wish to use the internal graphics when a graphics card is installed.

Fresco Logic xHC1 (USB3) Root Hub driver problem Code 31

I have the Ideapad S206 Windows 7 32 bit and have a driver problem which I believe is due to a Windows update at sometime. I get the following statement :-
"The device is not working properly because Windows cannot load drivers for this device (Code 31)"
Can someone very kindly please advise me how to sort this out. Apparently uninstalling the driver and then reinstalling does not work.

Lenovo B50-30 AIO touch screen stop working

I bought my Lenovo B50-30 AIO touch screen last year and approximately after 3- 4 months of use the touch screen capability has stopped working.. Contacted customer service but they are unable to help and they told us thay they will send someone to fix it but no call to schedule this visit has ever been received at all.. Can anyone help?

hi wileecoyote,
Welcome to the Forums.
Can you try the following:
1.. Press the Windows key‌ +R, type devmgmt.msc and press Enter. On the device manager, click View > Show Hidden Devices and under Human Interface Devices section, uninstall the HID-compliant device touch screen (this is the driver that controls the touchscreen).
- Sample image
When finished, reboot the system and open system properties to determine if the OS is detecting the touch capability.
   - Link to picture (Touchscreen not detected, proceed to Step 2)
- Link to picture (Touchscreen is detected)
2. Restart the machine and tap F2 to boot into the System Recovery options. On the menu, try to touch an item but don't proceed in doing the system recovery -- this is to check if the digitizer (the hardware part that enables touchscreen functionality) is working.
  - If the Touchscreen is working, boot back into Windows and backup important files then prooceed with the System Recovery.
  - If the Touchscreen is still not working even in the System Recovery menu then it's likely that the digitizer is faulty. Since you already called tech. support, I would recommend doing a follow-up on the repair ticket (your case number#) or send me a private message regarding the machine serial number and case # for me to check.

T61P Windows 7 Driver problem: Port_#0006.Hub_#0007

Am getting an error message saying driver not installed for Unknown Device. When I look at details, the location of the device is: Port_#0006.Hub_#0007. I found some great fixes to other driver problems I was having on the message boards, was wondering if anyone else had this problem and better yet had a fix!!!

A quick and painless path to take is install Lenovo System Update v4 onto your machine, run it, and install all critical updates.
In most cases, if you're missing a driver, this should supply it for you.

L430 multiple driver problems (ultranav and others)

Hello,
I have multiple driver problems with my newly purchased L430.
1) After hibernate the UltraNav driver randomly stops working. This means that the settings are grayed out and my old settings aren't applied. Sometimes the mouse pad and track ball also stop working after hibernate.
2) The hardware mute button and hibernate don't like each other as well. After resuming from hibernate with the mute button on the sound doesn't work anymore. Rebooting only helps if you have disabled the mute before rebooting.
3) The intel usb 3.0 driver can't be installed unless you want a lot of bluescreens.
I do have the newest drivers and BIOS (2.54).

It's ok my friend, I just hope I will be able to help.
Now to the problem. The thing that worries me the most and the reason I asked you to contact a Lenovo Repair Center, is the blue screens with the Intel Usb 3.0 installation. If the driver is correct this should not happen and most of the times it signifies a pure hardware problem, not a software one. Really, it just should not happen, period!
So please, before anything else, download and boot with a Linux Live cd, any distro you like (e.g. Linux Mint, Fedora, etc). Better choose a 64bit version. It's one way of determining if you're facing a hardware problem with the usb 3.0 ports.
The information you give is very useful and more or less complete, but I would like to also know the model of your SSDs, both the 2.5'' and msata.
Meanwhile, you can check either with the Linux Live cd or with Memtest86+ your ram. This does not seem to be a memory problem but it would be nice if we could exclude it from the suspects list. Many - if not most - of these problems are multifactorial and we cannot leave anything to chance..

Audio driver problem

I have what I think is an unusual symptom. My audio device comes and goes. When I have a device, it is a yellow Multimedia Audio Controller. Checking Device Manager tells me that I have no audio device installed. Why not? What happened to my audio device? I have not intentionally removed or disabled it, just one day it wasn't working. I visited Tech Guy and got advice from a few people and the prevailing theme seemed to be one of driver problems. So, I downloaded Realtek AC'97 Audio, attempted to install it but got a blue screen (not the BSOD) which said it was shutting me down to prevent damage to my computer and a full screen of info. It shuts down too quickly to read all of the info. Anyone out there got any ideas? I'm using a 6 year old factory refurb T43 with Win Pro.

@clairienz:
it looks, that mcq's T43 has flexing of the southbridge - that can happen to every notebook brand and model (my DELL Latitude had the same issue a couple of years ago). The USB 2.0 - message is an indicator for it.
The Lenovo audio driver in normal cases works fine with XP service pack 3, even it is an older driver.
One thing very often will be forgotten while installation:
Executing the downloaded package only extracts it to C:\DRIVERS\WIN\Audio. After that the setup.exe must be executed additionally.

Windows 7 auf dem Lenovo B50-30

Guten Tag. Nachdem ich mir kürzlich ein Yoga Pro 3 gekauft habe und mich mit Windows 8.1 so gar nicht anfreunden kann, habe ich mir noch dieses große "Sparbrötchen" Lenovo B50-30 gekauft. Das wird ebenfalls mit Windows 8.1 ausgeliefert, aber ich hatte gesehen, daß es dafür Windows 7-Treiber gibt. Sicher nicht grundlos. Tatsächlich konnte ich Windows 7 Home Premium 64bit mittlerweile installieren, und es läuft recht rund. Aber ein paar Geräte werden mir im Gerätemanager noch als "Unbekannt" angezeigt. Da das B50-30 derzeit recht günstig angeboten wird, hoffe ich, daß vielleicht noch andere mit diesen Problemen zu kämpfen haben. Wo gibt es die restlichen Treiber, die ich noch benötige?

Die Fehlermeldung hatte ich nicht. Ich bin allerdings so vorgegangen, wie in den Artikeln, die ich mir aus dem Netz kopiert habe. Und wenn gar nichts hilft: Festplatte ausbauen (geht total easy), in ein externes Gehäuse packen, an einen anderen PC anschliessen und von dort aus Partitionen löschen. Aber erstmal folgendes machen: Re: B50-30 problem with install windows 7Options‎10-03-2014 03:38 AM1. In BIOS select exit menu2. Load DEFAULT SETTINGS3. Find OS optimized defaults, make sure OTHER OS is selected!4. Select Boot option menu5.Make sure BOOT FROM LEGACY is enabled6. REORDER BOOT DEVICES INSTALLING WINDOWS 7 IIF YO CANNOT INSTALL WINDOWS (Windows cannot be installed to this disk. The selected disk is of GPT partition style). FOLLOW THIS TUTORIAL https://www.youtube.com/watch?v=DQf9YqbD8WI The solution is this.... I bet you are Getting the ACPI Error like this... Link to image Step 1: Shut down your Laptop. Step 2: Find the small NOVO button on Left side of your Laptop near the Power cord Point. Press the button. The System loads Boot Options.. Step 3: Click on the BIOs Setup Option. A Blue screen menu appears use arrow keys to navigate to Exit option and select OS optimized Defaults to Win 7 ( The Default is Windows 8 64 Bit) Step 4: If you are about to Install a Fresh Copy of Windows 7 Then Goto Configuration Tab and Change USB Mode to USB 2.0 (Original may be USB 3.0) In case you are already Running Windows 7 and the Problem was caused by Updating Your BIOS then Then rest the Bios by using the option given in the Status Bar. Step 5: Goto Exit and Select Exit Saving Changes. Select Yes The problem should be gone.. and if It doesnt... Be Patient. Open BIOS Settings again and tweak around... Boot Mode or Boot Priority etc. * Please refre to this Document -http://download.lenovo.com/consumer/hnt/lenovo_g40_30_g50_30_bsod_solution.pdf Hier: https://forums.lenovo.com/t5/Lenovo-B-and-G-Series-Notebooks/Windows-7-install-on-Lenovo-B50-30/td-p/1654059 To Install Windows 7:
1 Run BIOS by pressing Novo button
2.Go to Exit menu
3. Make sure that OS Optimized Defaults is set to "Other OS". If not - select it
4. Select Load Default setting above OS Optimized Defaults and confirm loading.
5. Set Boot Mode to "Legasy Support" in Boot menu. Boot Priority could be set to "Legacy First" as well.
6. Go to Exit and Exit Saving Changes
7. Press Fn+F12 during Lenovo Logo to select boot source, then select your ODD (or USB) with Windows 7 Instalation disc.
8. Press any key to start Windows 7 Instalation wizard.
Now you can install Windows 7 including setting up new HDD partition(s) inside Windows 7 standard installation Wizard,
