G50-45 dvdrw

My G50-45 has a dvdrw drive that reads fine, but fails to burn anything.  In windows, it says the disk burned correctly, but the disc it creates is unreadable.  In linux, k3b says it failed to burn the disc, and the disc is unreadable.  I have tried many times on different burning programs, and in different operating systems.  The drive is toast, and I have had the laptop for less than six months, I registered it for the warranty, so how do I request a replacement drive to swap it out?

Sorry to hear of your problems.  Before contacting Lenovo have you tried cleaning the lens with a soft brush ?  If the lens cleaning didn't resolve the issue then I would suggest you contact Lenovo Support.  You can find the phone number for Lenovo Support in your country or area by using the link below....

Explain the problem to support and see if they will send you out a replacment drive.  Page #36 of your model's Hardware Maintanence Manual will explain how to replace the optical drive.  The link below is for that manual. When working inside your system please follow all precautions and recommendations that are noted in the manual.

  • ITunes + Vista = my computer can no longer see my DVDrw drive...

    I just downloaded iTunes 7.6.2.9 onto my Dell Inspiron E1705 - and when I restart my computer, the computer can no longer see my Optical drive (DVDrw). I contacted Dell support, and they changed something in the regedit limits or something(I'm not a techy lol), and my optical drive was back.
    But the next day when I opened iTunes I got a message that says:
    "Warning! The registry settings used by the iTunes drivers for importing and burning CDs and DVDs are missing. This can happen as a result of installing other CD burning software. Please reinstall iTunes."
    So I reinstalled iTunes.
    I restarted my computer, and it could no longer see my optical drive AGAIN. My DVDrw drive gets an error that says "This device cannot start (Code 10)." When I check for solutions it says "Could not load driver software."
    I go back to Dell support and tell them my optical drive isn't working. They do the exact same thing to fix it (deleting some limit with regedit) and it works. I open iTunes, and I get the iTunes Warning (Setup Assistant Error).
    I asked the Dell tech what the deal was, and he said iTunes isn't compatible at all with Vista.
    But according to Mac's website it is...
    Anyone know what's going on?!?!

    I am having the exact same behavior as xhollysue!
    It goes like this:
    1. Install ITunes, lose optical disk drives hardware (they don't even show up in Windows Explorer).
    2. Use RegEdit to disable Upper Filters at HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE1 0318}, optical drive hardware re-appears.
    3. iTunes requires a re-install to permit CD burning, and your back to square one.
    I got the above fix NOT from a Dell technician, but, instead, from a Microsoft technician, which cost me $70.
    I would strongly urge Apple to research this issue and come up with a more reasonable workaround since (1) the iPhone is being adopted by many traditional MS users and the use of iTunes is an integral part of the iPhone technology architecture; (2) iPhone 3G is just now shipping and will bring even more into the Apple camp; and (3) iTunes is clearly a better media player.
    Come on Apple. Let's get some enthusiam and take advantage of this opportunity!

  • How to connect video-in cable with Qosmio G50?

    Hi
    I bought the Qosmio G50-11S, and received a video in cable with it. (Red/White/Yellow RCA jack to mini jack) But I cannot find any way of connecting it to my notebook, not the manual nor any online resources talks about it. The issue is I need to capture video from my video recorder to my notebook and the normal TV antenna comes with a lot of noise, so I which to utilize the video in cable. Any ideas?
    Thanks
    M

    Hello
    In the past Ive made some experiments with it. I wanted to create DVDs copying the material from old VHS recorder. Do you want to use the same recorder? Ive done this on Qosmio G30 but the principle is the same.
    The fact is that you must send the signal to the notebook and for this you must use video-in port.
    I don't see your Qosmio has several of them so I think only way to send signal into your notebook is to use antenna-in port. Which video-out port you want to use on your recorder?

  • How to connect satellite set-top box to Qosmio G50 using RCA video-in cable

    I want to connect my satellite set-top box to my Qosmio G50 laptop using the RCA video-in cable I received with the computer. (yellow, red, white RCAs and a Jack)
    Could you help me where should I plug this cable as I have not found any instructions in the users manual. (The user's manual list this cable on page 21, so it can be used for something somehow for sure!)
    (The set-top box does not have coaxial output, and I do not want to include another machine (eg. an old VCR) just to use coaxial connection.)
    Thanks in advance for your help!

  • Lenovo G50-30 - "No Bootable Device" error message when trying to install windows 7 via DVD-ROM.

    Hi all, Recently purchased a Lenovo G50-30 as a birthday present. After recieving the laptop, I tried putting a fresh install of Windows 7 64 Bit onto it. After changing the BIOS settings to allow legacy booting from the DVD drive and changing OS Settings to Win 7, I noticed I was getting an error reading "No Bottable Device -- Insert boot disk and press any key". After googling for a few hours on how to fix this I am still stumped and nothing seems to work. Has anyone had a similar issue or would know how to fix this?

    Hi omegafeggy,
    Welcome to Lenovo Community Forums!
    Im kind of confused with the sequence.
    Have you installed Windows 7 first then change the BIOS or You changed the BIOS first then Load Windows 7.
    Thanks

  • Can't find drivers for Lenovo G50-30 for Windows 7 32-bit

    Hi,
     I can't find drivers for Windows 7x32 bit for my new Lenovo G50-30. Looks like Lenovo support doesn't have them. Am I wrong?

    hi ziris,
    Can you try these drivers:
    Chipset:
    Intel® Chipset Device Software (INF Update Utility)
    Bluetooth:
    Bluetooth Driver (Intel, Atheros, Realtek, Broadcom)
    Camera:
    (AVC, Bison) Camera Driver
    If the  above drivers doesn't fix the unknown device under Device Manager, can you follow this guide on how to install the drivers via their Hardware ID or you may want to consider installing Windows 7 64bit (this would be best if you'll be utilizing 4GB RAM and above).

  • Lenovo G50-30 Unable to access BIOS settings after Windows recovery

    Hi
    I recently 'downgraded' a recently purchased Lenovo G50-30 with preinstalled Windows 8.1 to Windows 7 using a UEFI USB install on a GPT partition. I also updated the BIOS from A7CN40WW to the latest A7CN43WW and all was working fine. However, after performing a necessary restore of an system image created using the Windows 7 backup and restore tool, I am suddenly unable to access the BIOS settings, either with the novo button (I do get the menu to select BIOS) or with Fn +F2. All that happens is that I receive a blank screen with a static cursor in the upper left corner. I can however still access the boot menu Fn +F12. This is a particular pain as I obviousl can't select USB 3.0 in BIOS.
    Any help here would be greatly appreciated.

    OK, I managed to clear CMOS by disassembling and desoldering a leg off the the RTC battery but to no avail. The problem seems to be that BIOS a7cn43ww itself has somehow been corupted. In theory this should be able to be resolved by a reflash. The trouble here is there seems to be no way to reflash with a current or previous BIOS version, so I'll have to either wait for a newer version or someone may know better.
    C'mon Lenovo support this simply isn't good enough. It's a brand new laptop and I'm considering returning it for a refund.

  • Qosmio G50 No sound over HDMI

    *Qosmio G50 No sound over HDMI*
    Hi all,
    Hopefully anyone recognises the following and would be so kind to help me. I have searched the forum and tried severall of the offered solutions mainly applicable to Vista, but still.
    I hooked up my Qosmio G50 to my Philips LCD by HDMI cable. Picture is ok but there is no sound. I tested the cable with a Toshiba Satelite Pro L550 and it works allright. Picture and Sound are working. But that laptop has Intel HDMI audio.
    I'm running Windows 7 Home Premium 64 bit. I upgraded by Toshiba update DVD from Vista 64 bit. Sadly I do not know for sure if HDMI audio did work before that. I think so because I did use the laptop for watching a movie on a Panasonic plasma. But I can not remember if that was before or after the upgrade.
    Realtek HD Audio device is installed driver version 6.0.1.5923
    Realtek HDMI Output is selected als default playback device.
    Testing gives me graphical response ( the indicator flashes ) but no audible sound from my tv.
    Choosing the other audio device Realtek Digital output changes nothing and I do not believe that this would work anyway.
    I have tried removing the device and reinstalling the original drivers. I have tried REaltek drivers from their website.
    I have tried changing the view to HDMI only but that does nog change anything either.
    One thing that worries me is that under Sound / Realtek HDMI Output / properties / Supported Formats there are no formats present. The Satelite gives me DTS audio and some other. So I am wondering if there should be formats present and if so how can I change this / add any.
    Please forgive me if there are errors in the text. I am translating this from a dutch language version of Windows 7.
    Please help me. Any suggestions are welcome!

    Jeka-?? & PinkPanther thanks for your replies!
    The solution for the G30 you mention is not the one for me I am sorry to say. I have tried that one allready. Windows automatically switches on the HDMI audio out when I connect an HDMI cable. Connecting the cable before switching on the TV and laptop is a good thing to try because it eliminates possible problems with the connection. The connection in my case is ok.
    At some point I concluded that there must be a softwareproblem of some sort.
    I have found the solution over night. Could not sleep anyway. I did not know that the videodrivers are also handling HDMI audio out but in a way it makes sense. I have completely deinstalled the NVIDIA video drivers. After downloading the latest drivers and installing them everything works absolutely fine!

  • G50-70: empty DVD-drive clicking and freezing other drives for about 30 seconds all the time

    Hello board. Big problem. Seem to be the only one having this after searching the board:
    Brand new G50-70: When using OS from the SSD or using OS from the SSD and doing things with a USB-drive, the empty internal DVD-drive making clicking sound and sometimes freezing SSD read/write operation for about 30 seconds but all the time freezing USB-storage read/write operation for about 30 seconds.
    When freezing there's always clicking. But when clicking there's not always freezing except when using USB-storage.
    OS is Win81-64.
    An example scenario: connect USB stick, open terminal, type diskpart, dvd-drive clicks and freezes opening of diskpart for about 30 seconds, then the same may or may not happen when entering commands like clear the stick and format the stick.
    Any clues, why I have this issue? Thank you very much for reading.
    Solved!
    Go to Solution.

    hi georg43,
    it's possible that there's a software running on startup that's accessing the ODD when the machine is being used (especially if the ODD LED blinks when it's being accessed)..
    To check, you can perform a clean boot to temporarily disable apps & services running on startup. If the machine functions properly on a clean boot, you will need to enable the startup services/programs that you have disabled in groups of two or three (trial and error) to find the culprit. You can start by enabling the lenovo services and apps first followed by the Intel ones and observe.
    In addition, you can also try to disable the DVD-drive under device manager and observe.

  • Can I install a DVDRW drive on my Satellite Pro A10?

    I would like to upgrade the DVD ROM/CDRW drive (SD-R2412) on my Satellite Pro A10 to a DVDRW drive so I can burn DVDs. I have purchased a Toshiba DVDRW drive (TS-L632), as it is exactly the same size and shape as the existing DVD ROM drive, the same voltage (5v) and same connector.
    However, after installing and turning on the laptop, it is not recognised as being installed ie, there is no sign of it at all on the computer. Is this because the laptop is totally incapable of supporting a DVDRW drive, or have I bought an incompatible device? If so, is there a compatible DVDRW drive?
    Thanks in advance,
    fred.
    PS the exact model of Satellite Pro is PSA15E-0115Q-EN

    Hello
    All ODDs cannot be used on every notebook model. It depends on pin assignment. Toshiba offers the list of all compatible drives in the Users Manuals document.
    Ive checked Users Manuals for your notebook model and there you can find list of all compatible optical disc drives you can use with your notebook model. Check pages 4-8.
    Choose the best one.
    If you don't have it visit Toshiba download page. There you can find it.

  • How to install "YUAN FM100" on Qosmio G50?

    I recently purchased a new Toshiba Qosmio G50 laptop.
    From the first start up Windows keeps giving me a message saying 'Windows needs to install driver software for your YUAN FM100'.
    Google suggests YUAN is the company that makes the TV Tuner software - I emailed their support centre a couple of weeks ago, but have had no response.
    I can't find the driver anywhere - I've spent ages googling this.
    I'm running 64 bit Windows Vista, if that's relevant?
    In 'device manager', under 'other devices' Qosmio G50 comes up twice, both with the yellow warning exclamation mark.
    Should I disable both of these?
    Thanks in advance for any help you can give - please reply using words a 3 year old would understand!
    Thanks
    Steve

    Thanks to both of you.
    Short story - success!
    Long story;
    The driver isn't C:\TOSAPINS so I went to www.toshiba.ca (I'd already looked in the .au - Australia site, where I'd bought the machine).
    The driver is available for 4 different variations of Qosmio G50 PQG55C, however, I have PQG55A. I downloaded the driver anyway (for the PQG55C 043049) but it didn't work. 'Windows could not find driver software for your device'.
    So then I clicked setup in the downloaded utility, and it appeared to install the whole FM Tuner application. I have the impression my PC was asking me for a driver for a program which it didn't fully have, but then I'm a moron so what do I know.
    Anyway, all installed now, and it's not asking me for any more drivers.
    Haven't a clue how to open or use the FM tuner though...
    Thank you!
    Steve

  • Lenovo G50-30, Windows 8.1, Boot Probleme, ACPI

    Hallo zusammen,
    habe mein G50-30 mit Windows 8.1 Pro, 64bit laufen. Leider ist es der Fall, dass es beim starten teilweise, nicht reproduzierbar zu Verzögerungen kommt. Teilweise muss ich das Gerät durch 3-4 Sekunden druck der Power-Taste abschalten und anschließend neustarten. Gefühlt besteht das beschriebene Problem nach jedem zweiten Start.
    Alle Treiber sind installiert und werden im Gerätemanager auch als betriebsbereit und funktionstüchtig angezeigt.
    In den Windows-Logs finde ich immer nach dem auftreten des Problems folgenden Fehler angezeigt:
    Fehler - Ereignis 13, ACPI:
    : Der eingebettete Controller (EC) hat nicht innerhalb des angegebenen Zeitlimits reagiert. Dies deutet auf einen Fehler in der EC-Hardware oder -Firmware hin bzw. darauf, dass das BIOS auf falsche Art auf den EC zugreift. Fragen Sie den Computerhersteller nach einem aktualisierten BIOS. Dieser Fehler kann in einigen Situationen zur Folge haben, dass der Computer fehlerhaft läuft.
    BIOS ist auf der aktuellsten Version. (BIOS-Version/-Datum    LENOVO A7CN43WW, 21.10.2014)
    Was könnte ich falsch machen?

    Hallo Crowdy,
    in diesem Fall können mehrere Faktoren (Software, Treiber, Hardware) eine Rolle spielen. Hier einige Möglichkeiten zur Fehlereingrenzung:
    1. Energy Management
    Da der Fehler auf die ACPI-Funktionialität hinweist, kann eine Neuinstallation der entsprechenden Energie-Treiber helfen. Du müsstest die Software in der Systemsteuerung in der Liste der installierten Programme finden. Deinstalliere das Programm "Energy Management" oder "Energy Manager" und installiere anschließend diese Version:
    http://support.lenovo.com/de/de/downloads/ds039869
    2. Hardware-Scan
    Das "Lenovo Solution Center" ist meistens vorinstalliert. Du kannst es aber auch hier nochmal herunterladen: http://support.lenovo.com/de/de/downloads/migr-73784
     Wenn das Programm installiert und gestartet ist, gehe wie folgt vor:
     - links im Menü auf "Prüfung" klicken
     - auf "Hardware-Scan" klicken
     - auf die Schaltfläche "Scan ausführen" klicken
     - den Punkt bei "Ausführliche Tests ausführen" setzen
     - nach ganz unten scrollen
     - unten rechts auf die Schaltfläche "Starten" klicken
    Der ausführliche Test dauert ca. zwei Stunden. Nach Abschluss kannst du unten rechts auf "Protokoll anzeigen" klicken. Wenn alle Tests bestanden wurden, liegt kein Hardwaredefekt vor und ein Systemrecovery wäre ratsam (siehe nächster Punkt). 
    3. Recovery 
    Im Werkszustand muss das System problemlos funktionieren, sofern kein Hardwaredefekt vorliegt. Wenn das Notebook vorinstalliert gekauft wurde und die Festplatte nicht umpartitioniert wurde, benutze OneKey Recovery, um den Werkszustand zu laden. Nähere Infos dazu im Handbuch.
    4. Hardwareproblem
    Ich haben einen älteren Thread gefunden, in dem bei gleicher Fehlermeldung schlussendlich ein Problem mit einer Speicherbank bzw. mit dem Speichercontroller vermutet wurde:
    http://forums.lenovo.com/t5/ThinkPad-Edge-S-series/ACPI-Error-13-The-embedded-controller-EC-did-not-...
    Bei einem Hardwarefehler hilft dir der Support weiter, damit eine Reparatur veranlasst wird.

  • Lenovo G50 BIOS in this system is not fully ACPI compliant

    Hello everybody !
    I kinda have a problem as the title states.My neighbour has a Lenovo G50 she bought and came with windows 8.1 x64 ( which she doesn't like at all and in my opinion win7 is far more superior ). The thing is I wanted to install her the Windows 7 Ultimate but everytime the " loading files " ends right after it boots from the dvd I get a bsod with the message " The BIOS in this system is not fully ACPI compliant Stop 0x000000A5 "
    I tried all kind of different settings through the bios, changed from UEFI boot to Legacy / disabled secure boot / fast boot / I set the ACHI to compatible / but the end result is almost the same ( two times with different settings my screen froze with a red line over the top after loading the files )
    My question is what is the problem and is there a fix for it? (of course it is,but I don't know it )
     Thanks !

  • Lenovo G50-45 why is no USB 3.0 driver listed for this model

    I started a clean boot of Windows 7 x64 from USB as I'm not a fan of Windows 8 but since installing I've been unable to get the USB 3.0 port to recognize anything I plug in (was working fine before).
    I can't see a USB 3.0 driver listed on the support page for this model:
    https://support.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-g-series-laptops/g50-45-notebo...
    I've also read similar problems have occured on other manufacturers laptops and this was fixed by installing the chipset drivers etc in the correct order.
    Is there a correct order I should adhere to?
    Any help much appreciated

    I am having the exact same issue on my 2013 MBPr.
    I have two Seagate GoFlex USB 3.0s, one plugged into the regular 3.0 port (450MB/s) on the left and the other plugged into the high-speed (5GB/s) 3.0 port on the right. When doing a simple copy/paste from the one drive to the other, I observe the following speeds:
    Peak Read (USB 3.0): 36.2Mb/s (288Mbit/s)
    Peak Write (USB-HS 3.0): 48.7Mb/s (384Mbit/s)
    This is far below the 620MB/s for 3.0 and is more around the 35MB/s USB 2.0 standard.
    So, I'm likely to agree with the original compaintant that the 3.0 standards aren't being employed by the MacOSX USB drivers and I'd hope to see a fix soon for these issues lest people start moving off of the Mac platforms to other vendors who adhere to industry guidelines.

  • G50-30 System is unstable after BIOS upgrade

    After installing Windows 7 I decided to upgrade BIOS and picked the proposed update for Windows 7 64bit (http://support.lenovo.com/uu/en/products/laptops-and-netbooks/lenovo-g-series-laptops/g50-30-notebook-lenovo). 
    After applying the upgrade system boot failed. This issue was fixed using yapha7's advice (see this thread: https://forums.lenovo.com/t5/Lenovo-B-and-G-Series-Notebooks/Lenovo-G50-30-Bios-update-crashed-installed-win-7/m-p/1693051#M32265).

CPU consumption increases without any resorce-intensive task being launched. It iss understood that latter two issues might not be related to a BIOS upgrade. But they all appeared shortly after the upgrade.
    Also it is not clear if I'm able to use USB 3.0?
    The current BIOS version is A7CN47WW. Is it possible to rollback? Can you provide the original / any stable BIOS version (for Lenovo G50-30 Windows 7 x64) which is prior to the one available at the drivers download page? Thank you!

    hi a_demenkov,
    Just to check, have you considered reinstalling Win7 after you got the issues that you described after flashing the BIOs to v47?
    If you're leaning towards downgrading to the BIOS to v45, try the following:
    1. Boot into the BIOs and enable BIOS Back Flash.
        - Sample image
    2. The BIOS v45 download link is not listed but if you look at the the BIOS v47 file below, you should be able to get v45 by renaming:
    BIOS v47
    https://download.lenovo.com/consumer/mobiles/a7cn47ww_64.exe
    to
    BIOS  v45
    https://download.lenovo.com/consumer/mobiles/a7cn45ww_64.exe
    If you're not able to flash the BIOS inside Windows then you may need to do it under DOS.
