Lenovo Yoga Flex :: IdeaPad 11s Camera Screen Black With No Error Message
Jul 7, 2014
My integrated webcam on my lenovo yoga ideapad seems to be malfuncitoning. When I try to open any camera using applications the screen is black with no error message or viewable problems. When I check in device manager the camera says all the drivers are updated and it is in working condition.
Things I've tried/ Things others have suggested and did not work:
Trying it in other apps besides camera
Check device manager for driver issues
I use a USB MIDI keyboard (Akai LPK25) with my Ideapad. I've not previously had an issue with this configuration, but since about a week ago, as soon as I plug in the device the touch screen becomes disabled. Removing the device doesn't restore touch screen functionality; I actually have to reboot.
Was there a recent USB upgrade that's causing this issue?
I have a Lenovo Flex 15 device (i5 version with 4GB ram). I upgraded it with an SSD, reinstalled Win 8.1 in UEFI mode. Everything works fine.
Next I replaced the 4GB memory with an 8GB version (same speed, Kingston) now the machine won't boot anymore, all it shows me is a black screen, both with power switch and novo button. If I reinsert the original ram it boots just fine again. The 8GB ram is not faulty, I tried it in another device and it works. I also tried disabling secure boot in bios but it's the same problem.

I've been having problems with the dreaded "black screen" when starting my Yoga13 (but only somethimes!). To try and narrow it down, as there seem to be so many things that can cause this, I went into the Bios settings from "F2" and setup it up to ask for a "Power on" password before starting windows.
What I have discovered is that when the black screen occurs its BEFORE the Bios asks for the initial "Power on" password, ie I cannot see the box asking for the password and so Windows has NOT yet started to load. To overcome this, I just press the power button to switch off the system, wait 20seconds and then it will usually start.
Once past this, no errors ever occur on the windows side.
I just formatted my yoga 2 pro, downloaded the drivers and ran the Bios Update. I followed the instruction on the read me, ran the .exe, clicked next/ok until the laptop restarted and if I'm not mistaken a red menu with a progress bar showed up. At that point I left and when I came back a few minutes later the laptop was turned on, the screen lighting was on but the display was black, the keyboard backlights were also turned on and everything else was off. The lights on/near the power button that signal if it's turned on and plugged to the AC are turned off.
It's been like this for over 30 minutes now, no signs of progress. I'm not very keen on turning off or unplugging the laptop while flashing the BIOS, but at this point there's not much else I can do.
I don't think this is the same screen flicker that is experienced by the few others due to auto brightness problems...
It's flickering black and then the whole thing turns unresponsive after a while...and although the video shows it happening during a low light environment, i have had this encounter during a brightly lit area as well...
I've posted a copy of what really happens on google drive. Is this a case of motherboard problems? I jsut got my laptop about 3 weeks ago. Any chance for a 1-1 exchange?
When i boot the computer to windows, a message pops up saying that i have to not charge the battery up to more than 70%.
It's says that i have to set up something in power consumption options but when i went there i didn't see something relevant to the battery lifespan(in french). Kow to set this up ? between i'm always on the sector (AC).
I have Lenovo yoga 2 pro with a clean installed Windows 8.1 Pro. My Lenovo Energy Management doesn't function properly.
When I open the Energy Manager and click the menu button (the one with 3 dots and 3 stripes) the energy manager freezes and I can't do anything with it. It doesn't let me click any buttons or even close it with the little x. I can only close it from the little task bar icon.
There is another weird thing, but I don't know wheter it's related: Every time I open the energy manager I get a windows security message from Outlook where I have to fill out my username and password. This only happens if outlook isn't running... This security message dissappears within a few seconds without doing anything, and then for a second another outlook message is displayed that says something about accessing a server... I don't know wheter this is related to whether the energy manager doesn't work, but it seems kind of strange to me...
I tried reinstalling the Energy Manager (v. 220.127.116.11) and tried installing a newer one (v. 18.104.22.168) found here: [URL] ... But I keep having the same problem with the security message and the energy manager freezing.
I know, that F10 it's a Windows-only laptop and Linux not officially supported on it by Lenovo,
Have purchased just yesterday a new IdeaPad F10, Spanish edition
Have successfully installed Ubuntu 14.04.1 x64 on it. Have preserverd the possibility to boot Windows and Recovery.
The installation was smooth, every things was working fine, but:
After the closing the cap, the laptop was going to hibernate, and then no way to resume or get it on.
Have tried to press the power button for a 8-10 second then disconnect the AC cable.
When doing this the power indicator becomes white for around of 30-40 seconds then off, during this nothing is happens, the screeen is black, no fans no HDD activity noise. Only if pressing the Windows logo on the screen it´s become giving a some sound, not a beep but it hears like... a rattle or something like..
It is dead now? I belive that disconnecting the battery can solve this but it´s mean loosing the warranty, because it´s necessary to remove the back screws. Or it´s possible to reanimate it by the other way?
My Lenovo Ideapad Flex laptop does not switch on when I press the power button. It was working till this morning, when I switched it off (via an operating system shut down in Windows 8.1). When I tried to turn it on an hour later, I found that pushing the power button has no effect at all.
I tried pushing the novo button. In this case the laptop does turn on and shows the "lenovo" welcome screen for a few seconds. However, it promptly switches off again. The symptoms do not depend on the laptop being connceted to power: they are exactly the same in the two cases.
I have an acer aspire 5610 and am having a problem. Everything was working perfect then randomly one day it went black. When i log in it still has the windows sign and everything but when i am in the desktop it is black there is no start bar or Icons or backround. Basically my GUI is gone. but i can still see my mouse pointer. I found that i can run programs by opening task manager and clicking file and start new task then browsing on what used to be my desktop for the internet icon. this works and everything works as it should. but i get an error message fo most all programs other than internet. i have attached screenshots of my desktop and of the error message that pops up. at this point i dont care about salvaging the stuff on my comp just want to reset it back to factory defaults. I have tried recoverry CDs that were made and it doesnt recognize them, i cant get to eRecovery due to the error message
I've been trying to use a Logitech ultrathin touch bluetooth mouse and microsoft sculpt mobile bluetooth keyboard with my ideapad. I'm running Windows 8.1. Both work fine for a while but then it appears they lose the bluetooth connection. This seems to often coincide with access network/internet over WiFi. The only solution is to call up the Bluetooth manage devices setting and let it reconnect. If I leave the manage bluetooth device page open on a second screen it works, but clearly its not ideal!
I was running the Lenovo driver for Bluetooth but I've tried removing it and using the Generic Windows driver. So far though the same happened after a short while.
I have a DELL XPS 15 L521X, (Mid 2012), I have Windows 8 on my machine, Suddenly when I restart my PC a black screen is visible without any error, but system continue beeping. Then I press Power button and shutdown it, after some time when I start it again, its start working normally.
Once system starts its start working without showing any hardware or software problem whenever I shutdown or restart, sometime its start working sometime its continue beeping without showing any error.
Loving my Yoga 13 so far have had it since Oct 26th when it was released. Like everyone else I had some issues with partitioning yadda yadda yadda, got that taken care of, but lately I've noticed that my screen brightness seems to flicker, ALL the time, when switching from program to program if the color changes on the screen I notice that the brightness changes as well in noticeable increments. I have the automatic brightness setting set to OFF, so I can't imagine that's the reason.
I have a crack on my screen that starts in the bottom left and spreads to almost the top right. It is not bad and everything works fine except for the touchscreen. Only half the touchscreen works and sometimes the crack causes the other half of the touchscreen to act on its own and its very annoying and messes me up when I try to surf the web or use Microsoft Office. Is there a way I can disable the touchscreen?
I have just bought the Flex 15. I looked at the power settings and set the brightness, but it is ignoring the settings and always either darker or brighter than I want it. It keeps flickering between being darker and brighter and it's giving me a headache. It is unplugged if that makes a difference, I haven't used it plugged in yet to know if it does it then. How can I stop it? I've looked through the settings and can't find anything.
I installed a new video driver today (updated to newest), and all of a sudden my screen is flashing before it rotates when i flip it to tent mode or tablet mode. to be specific, when i flip the screen over, the screen flashes off and back on, before rotating. this has never happened before.
I got my new Yoga 2 Pro last week and the screen rotation worked properly. I decided to wipe the partitions and install my own version of Windows 8.1.
Since then the screen rotation doesn't work. The screen rotation button doesn't do anything and I don't have the 'Enable auto-rotate' checkbox in the resolution screen
In my device manager I have an error on 'HID Sensor collection' saying "This device cannot start" (Code 10). Failed to initialize sensor from HID collection descriptor". I am not sure if this is related.
I had a problem for a few days now, sometimes, out of nothing, the screen color turns yellowish....like a warm color....i right click in the home screen, personalize, display, calibrate color, the template for color calibration appears, i enter next...and voilá, it comes back to the cold white color....it just happened as i turn from tent mode to laptop mode to wright this thread
I've noticed the screen on my Yoga 2 pro tries to automatically adjust the brightness of the display depending on how dark or light the content being displayed is... I want to figure out a way to make it stop. For example, my desktop background is just plain black, and when i got to my desktop, it starts to dim by 4-5 levels lower, and then when I go back to my browser, it reverses and starts to turn up the brightness by 4-5 levels. I've already tinkered with all the power settings and even the advanced power settings to turn of auto dim/automatically adjust brightness etc and all those settings but it still does it.
Just picked up this model from Best Buy yesterday. Like everyone else in the large thread I am having the yellow color issue as well. However, I have another issue that I can't seem to find any information on.
The brightness on my screen is constantly adjusting. It is most obvious when making the move from the desktop to Metro. After hitting the windows key, I can see the brightness increasing in stages (about 4 times) after flipping over to Metro.
I have disabled Auto-Brightness under the Change My PC Setting -> Power and Sleep menu. I have also disabled Enable Adpative Brightness under Windows Power Mangement but the issue still persists.
Is there any other location I might be missing a setting that can be affecting this ? Brightness is set to full and keeps dipping down.
Just picked up my brand new Yoga 3 Pro a few days ago and on the whole I love it, except I've just noticed there's an odd issue when listening to music (whether it be local or streaming thru spotify).
If I'm browsing a document in Word or even when accessing the Lenovo Support screen from the Start menu, any left to right horizontal scrolling (either with the touch screen or touchpad) causes a crackling interference to the sound. I did notice it would crackle as the Discussion forum cards were loading up and appearing too.
It's not the physical speakers themselves because this occurs thru headphones as well.
Strange thing is it doesn't occur when scrolling vertically through a document.
On the whole it's not a HUGE problem, but given it's a brand new 2grand laptop, now while it's still brand new and I haven't even had a chance to load much onto it. How to stop this from happening?
I recently upgrade my Ideapad S10 to 2 megs, which I understand it is capable of recognizing. When I turn it on however, I only get a black screen. Some forum posts suggest that updating the BIOS might be necessary, but the only BIOS update I can find is for Windows XP, and I am running Windows 7.
