Webcam not working plus error 43 message (might be associated) on Samsung NP700Z5C-S01UB Series 7 Laptop - 15.6"

I have a fresh install of windows 7 Professional and installed all the drivers to my knowledge and all the important updates are installed. Working on the Microsoft.NET updates. Any suggestions??

Does Device Manager show any problem devices?

John

 

Yes or shows unknown USB driver

*Unknown device in USB has an error 43*

My best guess would be that either the wrong or no Chipset drivers were installed. Did you use SW Update to get drivers?

I suggest you do another clean install, using the steps in this Win7 install guide (post #40 in that thread). It includes which drivers to download before you start, which ones to install automatically using SW Update, and which to install manually afterwards.

 

I used SW Update to get most of the drivers. I got some from Samsung's website and I think I might have installed the windows XP driver as well. I'd rather not do a clean install as I bought this laptop with Windows 7 Professional cleanly installed so I don't think I'd have all I need to do one.

I've downloaded and installed all the drivers to my knowledge. If I just gave up on it and bought an external would I experience this problem still?

An external webcam would be detected as a new device and Windows should be able to configure it provided it can find the driver.

However, I would recommend that you first spend more time trying to persuade Device Manager to find the right driver for the internal webcam.

John

 

Okay what would you recommend I try on device manager?

The webcam on your model is a USB device supported natively by Windows 7 (and newer), not requiring any external drivers, as long as the underlying Chipset and USB drivers are installed. My understanding from your original post was that this was a fresh install of Windows 7, that is why I referred you to our Win7 install guide -- which is almost certain to get it working.

But if this is the installation with which you received the computer, I can understand why you don't want to re-install. There are also some risks when installing Windows on this particular model, if it is one that originally came from Samsung with Win8. (If it has a SecureBoot setting in BIOS and OS Mode Selection is set to UEFI OS, you must be very careful about how Windows is installed).

OTOH if you installed a mix of some WinXP drivers, some drivers from samsung.com (which are outdated) and some from SW Update, Windows really could be a mess. And it is likely that whoever installed Windows before you received the computer (assuming it wasn't Samsung) didn't do it right or didn't know that updated Samsung drivers must be obtained through SW Update. So we have no way of knowing the state of this installation.

The best I can recommend is to uninstall anything you installed, using the Programs and Features control panel -- and even by repeatedly Uninstalling those devices in Device Manager and selecting Delete the driver software for this device. Then install the drivers listed in the install guide, simply by letting SW Update install them for you. Again, in particular make sure that Chipset and USB3 drivers are installed.

The best thing would be if this is a model that originally came pre-installed with Win7 (meaning it has a different BIOS with less risks) and if the original Recovery partition is still intact on the disk. In that case you can simply press F4 to boot Samsung Recovery Solution and restore the computer to factory state. Then use SW Update and Windows Update form there.

Please keep us posted and we'll see what we can do to help.

 

I'm almost certain that it came with Windows 7 Home Premium but they installed a fresh 7 Professional. I'll try uninstalling the chipset and USB3 drivers. I didn't see any USB drivers available on SW Update last time I checked though.

You can check in BIOS if it has a SecureBoot option (on the Boot page). If so, it came with Win8 originally. Otherwise it came with Win7.

There is a USB3 driver listed in SW Update under Win7 drivers for NP700Z5C-S01UB (I checked using Find Model). If it doesn't offer to install it for you, it may already be installed. Do you see a USB 3.0 controller in Device Manager?

 

Interesting, well secure boot and something else I had to change were enabled the second time I tried to boot it and it got stuck until I changed it, so maybe it did. I'll check and see for the drivers though

I was going to take a screen shot but this was faster. Apparently they're all installed. I'll remove the Chipset and USB 3 driver and get them back through sw update

Sent from my SPH-L720 using Tapatalk

 

It was probably Fast BIOS/Fast Boot you had to enable. But the fact that your BIOS has that SecureBoot option almost certainly means the computer came with Win8 originally. It also means you have to be careful if you ever need to re-install Windows.

Thank you. It seems like Chipset and USB3 drivers were already installed. In fact, that looks like a pretty standard Samsung installation there -- which is good. But it also means if you still cannot get the webcam working, we have to start considering that it might be defect. I'm not concluding anything yet, though.

 

I was starting to come to the conclusion that either the switch back down messed it up, it's disconnected(or incorrectly connected) from the motherboard, or the wrong drivers are installed because I downloaded some from SW Update and some from the support page. I don't remember getting any errors when I started using it. Just no recovery built into the storage

I would also check if you have the latest driver and firmware for the USB 2.0 and USB 3.0 hubs. Samsung don't normally bother to offer these but they are available from here. You'll have to do some research to identify the hub / controller models.

A few USB-related issues have been fixed by these updates although they are usually USB 3.0 issues and I would have expected the webcam to be connected to the USB 2.0 hub.

John

 

Okay I translated the page.
Should I be looking for USB 3.0 CHipset drivers by intel??

 

No, look for the USB Host Controller. It might be Intel - what is listed in Device Manager.

I can only talk from experience with my NP900X4C which has the Renesas controller and updatable firmware as well as a driver.

It might be easiest to use your favorite search engine to look for driver and firmware updates.

John

 

The NP700Z5C should have an Intel USB3 host controller (deduced by inspecting the USB3 Win7 driver for this model found in SW Update). Most likely its USB2 host controller is part of the chipset (Intel too).

Getting the webcam working should not be difficult at all on your model. In all of the 2,700 posts in the NP700Z5C Owner's Lounge thread I don't recall any discussion of the webcam not showing up (though some had problems with its image being too dark). And a high percentage of participants in that thread performed new Windows installations.

If your installation was performed correctly by the previous owner (which it would seem from the screendump your provided, and the fact that everything else runs smoothly) I am beginning to think a hardware or connection problem is more likely. These generations of Series 7 models had a lot of DIY work done (swapping disks, optical drives, WiFi adapters, and even screens) and I can see how a missed or broken connection to a webcam could easily happen.

If you want to open it up and inspect it, we have a Series 7 disassembly guide thread that should help.

Edit: As one other thought, you could try and install the CyberLink YouCam software that Samsung provided with these models. It may install its own driver and do a more thorough job of detecting the webcam. If you don't have the Recovery partitions anymore (which contain a SystemSoftware folder with all the original software, used by SW Update when no internet connection is found) you can try the link on this Samsung support page.

 

I'm pretty sure it's connected otherwise it probably wouldn't be listed as an unknown device. I installed cybercam you can from their website and it claimed to have installed drivers when it was installing but I'm still getting a dark static(TV like) like picture on the Webcam.

You're right, it's probably connected then. And considering it's serial (USB) the ID information travels on the same wire as the video, so the connection is probably correct. The cable or connector could be worn or unstable, that could still cause it to be detected, but not working.

Do other USB2 devices work correctly? Say, a video camera? If yes, I doubt it's a driver issue.

Edit: How do you know that the unknown device in device manager is the webcam?

 

That's a good point. Well worst case scenario I'll just buy a better webcam that clips on to the computer.I've plugged in a USB flash drive that seemed to work correctly. Wouldn't a video camera install separate drivers to work? I'm assuming that's what it is cause that's the only thing on the device not working. The replacement webcam I'm looking into is a plug and play. Would drivers prevent this from working?

Sent from my SPH-L720 using Tapatalk

 

I am guessing if you plugged in a videocam (and certainly an external webcam) it too would (or at least could) use the built-in drivers. It that DOESN'T work, you'll know it's a driver problem and the internal webcam might be OK. If it DOES work, you most likely have some kind of defect or poor connection on the internal webcam.

 

Hmm well let's assume it's drivers until we've done all we can then I'll get an external one to see if that works.

Sent from my SPH-L720 using Tapatalk

 

Other than a fresh install, and trying with another device (videocam or webcam) I cannot think of anything else to test on the driver side.

 

Hmm well I'll try looking for updated drivers like the other member on the forum suggested then I'll see if I can borrow a webcam to see if it's a driver issue before I purchase the new webcam

Just a thought but how about booting up a Linux Live CD?

That usually does a good job of hardware detection so if the webcam works under Linux then we know it's a Windows / driver problem and not hardware.

John

 

That's a great idea!

But make sure it's a recent version of that LiveCD. This model is on the list of ones that are prone to UEFI bricking, and late 2012/early 2013 Linux distros had a habit of triggering that. I don't think I remember LiveCD's causing it, but I couldn't say for sure.

 

Through Googling for a while I found that I have the latest USB 3.0 drivers as well as Chipset drivers. I didn't see any USB 2.0 drivers in my search and there are none listed in SW Update so I'm assuming they don't exist for this model. I think they might've installed incorrectly or something though so I'm including a picture of my error. What should I Uninstall and reinstall?

Don't worry about USB2 drivers, it's part of your chipset.

Did you see John's latest suggestion to use a LiveCD/LiveUSB to test the webcam?

Edit: And looking at that screendump, I agree, it does look like the unknown device is your webcam (which I asked earlier how you could be sure).

BUT, it could also be your Bluetooth adapter, which is probably connected through USB as well. If Bluetooth is disabled in Easy Settings (and was disabled when Windows was installed) it may never have properly installed drivers for it. Check in Easy Settings (Fn-F1) that Bluetooth is enabled (under Wireless Networks, if I remember correctly).

It's a long shot, but IF Windows suddenly picks up that unknown device as your Bluetooth adapter, that means the webcam isn't detected at all -- and is most likely dead or disconnected.

This is what the USB device tree looks like on my NP700Z3A after selecting View-Devices by connection in Device Manager. (I have ASMedia USB3 where yours is Intel.) The highlighted USB Composite Device is the USB controller for my webcam.

 

Hmm well I do have a black 4gb flash drive so I could try that. Could you guide me through that? Like what should I download?

Sent from my SPH-L720 using Tapatalk

 

The last LiveCD I used was two years ago -- before the great bricking debacle of 2013 which started with consistent Linux brickings. I used PartedMagic back then, but somebody has since turned that one commercial. For $5 you could still give it a try -- just ask their assurance first that it won't brick your Samsung laptop. They should understand exactly why you ask.

As for other LivdCDs, I am afraid you will have to Google your way through that.

 

Hmm well I won't really have time to work on that until Monday due to packing and temporary moving I'll try a LiveCD then

Use method 2, tested and working..

 

I just plugged in my friend's Logitech webcam and installed drivers nice and quickly and it opened just fine with youcam (trial I downloaded a while back)

Sent from my SPH-L720 using Tapatalk

 

Thank you for that update. So it seems USB and basic cam drivers are ok. Did Windows automatically detect the external webcam and select drivers?

In any case: I cannot think of anything more to test this webcam beyond the LiveCD/LiveUSB suggested by John. I think something is either broken or not connected properly.

 

Windows automatically detected the Webcam and selected drivers. I forgot about the LiveCD/LiveUSB. Is there a free way of safely going about it?

Sent from my SPH-L720 using Tapatalk

 

These things are normally free, I was surprised when I saw PartedMagic (which is the only one I've used myself) had become commercialized. I would search a little and see if you can find a free version of it. Or just start googling LiveCD and see what else you find.

The principle is it's a prepackaged ISO (which you flash to a CD or USB) containing bootable Linux with drivers for many devices, and typically containing a number of useful disk management and other utilities.

But again, do make sure that whatever you use supports Samsung laptops in UEFI mode, since there were some problems with Linux on Samsungs late 2012/early 2013.

Otherwise you could take the laptop to a local repair shop and have them check the webcam. They'll likely have a LiveCD or WinPE disc they can test.

 

Hmm well I did some research with Google and only found recommendations not to use it. I might be able to get it to a local shop this weekend but there's still the same risk of them bricking it. I was given $50 in Amazon credit (my choice) for the seller not double checking that the WiFi was working so at this point would it just be better and safer to disable the unknown device (to get rid of the notification) and just purchase a new, higher quality, multipurpose webcam?

Sent from my SPH-L720 using Tapatalk

 

I would expect any repair shop to take responsibility if they end up bricking or otherwise damaging a computer during their repair.

But you can also just get an external webcam and snap onto the display. It's more hassle with the cables and all, but as you say, the picture quality may be better.

Only you can say whether it's worth the effort of spending more time trying to get the built-in webcam working.

 

I think I'll just go with the external webcam. Thanks for all the help

I understand. I wish we had gotten it working, but sometimes enough is enough.
