Lenovo 3000 N100 audio problem

i use a 3000 N100 0768-B9G notebook with win Xp for a year and for some reason i had to format the Hard drive yesterday. i reinstalled my Win Xp and visited the site and downloades the audio drivers for the sound but nothing happend there was no device. then i downloaded the system update programm. it downloades all of the drivers including one for audio (different from the one from the lenovo site) and this time i had a audio device (not the old one though) my speakers were off and when i pluged external speakers to the speakers in the sound was horrible...what can i do?

Problem is that I have downloaded ALL DRIVERS from link you provided (www-307.ibm.com/pc/support/site.wss/product.do?template=/product.do?template=%2Fproductpag_1";return this.s_oc?this.s_oc(e):true">http://www-307.ibm.com/pc/support/site.wss/product.do?template=/product.do?template=%2Fproductpage%2...) but audio, video and network controller still doesn't work.
Please, does anybody know where is possible to find 'working' drivers? Drivers provided by above link are not for Lenovo 3000 N500 configuration. Neither, on this configuration is not possible to download Windows XP SP3.

HP ProBook 4530s AUDIO PROBLEM WIN 8.1

Hello. I have HP Probook 4530s. After I installed Windows 8.1 update 1 the sound driver stopped working properly. When I want to play some music, video or even system sounds, sound appears after 1-2 minutes. At that time HDD usage is 100% cause of windows audio device graph isolation. I’ve installed that IDT High Definition (HD) Audio Driver from HP’s driver support site, but that’s not working. As I see in device manager driver’s release date is 24.10.2012. I think, it’s too old for Windows 8.1. Can you help me? Is there any other newer version of that sound driver?

Hi,
Please using Device Manager to uninstall the existing driver and try the following driver:

Graphics display problems (dialog boxes) Lenovo G50 AMD A6 Win 8.1

Graphics display problems Lenovo G50 AMD A6 Win 8.1 Greetings to all. After having spent a number of days trying to find a solution to a display problem, I turn to this forum for help. I own a Lenovo G50 AMD A6 Win 8.1 ever since November 2014, and have had display problems ever since the first day, be it while using internet (Firefox or Explorer) or various software (Text editors, etc.). Many dialog boxes, including colour settings and controls (open, close etc.) either have an inappropriate appearance or even do not appear at all! I manage to "click" on the right places using memory: most areas are INVISIBLE! Another example would be that I do not see any backround colour or image on most webpages such as this one).  Some suggestions included checking for graphics updates (but the drivers used were already up-to-date).  I 'd be most obliged for any new suggestions. Thank you very much. George

Greetings to all, I finally decided to express my utmost discontent with- the Lenovo G50-45 I bought before Christmas 2014,- the summary response with inappropriate links that I received after exposing my problem- the fact that I tried to dowload the following graphics driver  (Beema) AMD Driver (VGA, HDAudio, SATA) for Windows 8.1 (64-bit)
exe
526 MB
Windows 8.1 (64-bit)

I find it quite disrespectful to NOT provide customers with EASY support, as well as avoiding to answer their requests for further help when some simplistic "assistance" that one can find almost anywhere on the web leads to no further solution. I shall not repeat the problems I have faced till now: vide supra. The problem, however, is NOT just with browsers.I simply cannot see any dialog box content and colour in MANY software programs, such as OPEN OFFICE; for instance: PRESENTATION colour dialog boxes show BLANK squares instead of squares filled with different colours. This has occured AVER SINCE DAY ONE! Finally, a new bug has appeared: Windows 8.1 keeps popping up some email program to which I am invited to register - I never created a Windows email account, and certainly don't intend to do so.NOR shall I accept some "Lenovo Service Bridge", however "discreet and inoffensive" it might be. I don't know if there are any legal grounds for customers to complain for all these problems. I DO know, however, that I shall NEVER buy a LENOVO device ever again. The pricing and processor might be competitive => yet, the support that ensues is, as far as I'm concerned, LAMENTABLE. To make a presentation, I have to switch to a Samsung R20 using XP..... What is the meaning of all this? George

Lenovo G50-70 Bluetooth/Wi-Fi problem in (32bit) window 7

hello , recently i installed window 7 32bit on my Lenovo G50-70 laptop with window 8.1 (64 bit) installed (as default).
but found bluetooth and wifi not working
I downloaded 515mb driver file from http://support.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-g-series-laptops/g50-70-noteboo...
After unpacking I get a Atheros, Broadcom, Realtek, Inte folder with "Setup.exe" file and when I'm trying to use it there is only a "Warning" window with message "No Appropriate Driver to be installed"
I checked BIOS settings too - there's also Wi-Fi enabled
help!!
and as i can see, most lenovo have this problem why??? alot of people in this forum also complaning the same issues..
Nitesh
Solved!
Go to Solution.

hi Nitesh,
The "No Appropriate Driver to be installed" error usually pops up if the installer can't find the specific hardware ID(s) to install the necessary drivers. This may happen if you have a different type of bluetooth adapter (eg. Intel wireless +bluetooth combo)
Can you try the following:
1. If the Network Controller (wireless adapter) is present under Device Manager, can you install these drivers first and reboot if necessary:
Lenovo Energy Manager
21.4MB
WLAN Driver (Atheros, Broadcom, Realtek, Intel)
267MB
2. When finished, check if you can now see the wireless and bluetooth adapter under Device Manager (see Bluetooth and Network Adapters) and press the airplane mode key (F7) to enable these devices.
- Sample Image
Let me know how it goes.

Lenovo G50-80 80E501E9GE - WLAN Probleme

Hallo, ich habe mir vor Kurzem einen Lenovo G50-80 gekauft. Installiert ist das Betriebssystem Windows 8.1 (das war vorinstalliert). Ich habe von Anfang an Probleme mit dem WLAN. Immer wenn der Laptop in Energiesparmodus oder nach dem Herunterfahren, neu hochfährt, erkennt er die WLAN-Verbindung nicht, obwohl diese mit automatisch verbinden hinterlegt ist. Hier erscheint immer die Meldung Verbindung begrenzt. Erst nach Ausschalten des WLAN Routers erkennt der Laptop die Verbindung. Es kann aber definitiv nicht die Lösung sein, jedes Mal den Router neuzustarten. Ein Laptop in dieser Preisklasse sollte eine automatische Verbindung ohne Probleme drauf haben, mein alter Toshiba läuft ohne Probleme mit meinem WLAN Router. Bitte um Hilfe oder Angabe ob ich den Laptop in Reperatur geben muss. Das Programm Fehlerbehebung brachte auch keinerlei Erfolg! Grüße

Hallo Laptop2, willkommen im Community-Forum.
Der Vergleich mit anderen Geräten ist immer etwas vage, da das WLAN-Modul, die Treiberversion oder der Stand aller Systemdateien völlig unterschiedlich sein kann. Außerdem fällt oft die Kompatibilität zwischen Router und WLAN-Modul unterschiedlich aus.
Im ersten Schritt würde ich den aktuellsten WLAN-Treiber von Lenovo installieren:
http://support.lenovo.com/de/de/products/laptops-and-netbooks/lenovo-g-series-laptops/g50-80/downloads/DS101669
Schau dann bitte, ob die Tips aus diesem Artikel helfen:
https://support.lenovo.com/us/en/documents/ht080645
Was du weiterhin testen kannst:
- die Bandbreite des WLAN-Adapters fest auf 20 oder 40 MHz einstellen (wieder über Rechtklick auf das WLAN-Modul im Gerätemanager -> Eigenschaften -> Erweitert)
- den Echtzeitschutz des Antivirenprogrammes testhalber einmal deaktivieren / pausieren. Eventuell ein Update durchführen oder auf ein anderes Programm auweichen.

Workaround for some W510 Audio Problems. Lenovo, please take a look at this!

Hi all
I believe most or all of the people are affected with poor sound quality of W510. I do believe there are some people who bring their laptops along and not convenient to get a external sound card and external speakers on the road. I am not too sure, but what I think that causes audio problem in W510, T410 or T510 is due to the implementations of Combo Audio/Mic Jack. So far, I have not heard any audio problems from X201 or W701/W701ds with a separate mic and audio jack (1 green and red, instead of 1 combo) Listed machines are using Conexant 20585 SmartAudio HD Sound Card.
The workaround is to force install Conexant 20561 SmartAudio HD Driver through Device Manager
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-73721
Problem Partially Resolved
1. Using Audio Director - Classic mode enables you to use both internal speakers and external speakers/headphone simultaneously. (By right, this should be in Multi-Stream mode, due to this driver not programmed for W510). However, the volume of the internal speaker will be reduced by half if an external speakers/headphone is plugged.
2. The sound quality is improved (tested with internal speakers).
3. Solved Irregular Volume Problems.
Drawback of using this driver
1. Using Multi-Stream mode in this case would not enables you to use both internal speakers and external speakers/headphone simultaneously. However it would just make your internal speaker to be louder. External speaker/headphone would not work if Multi-Stream mode is selected.
2. Custom EQ is not usable, if used, only the right channel of internal speaker, external speaker/headphone would work, and the sound quality will be like a spoilt radio.
3. Only Voice (VoIP) EQ is optimized for external speaker/headphone. Using Off, Jazz, Dance or Concert EQ would make you feel that the vocal (singer's voice) is diffused, blurred like excessive 3D effects.
4. Even if any preloaded EQ is selected, after system has been restarted, the selected EQ would still be saved, but the band (31Hz - 16KHz would be changed back to Off EQ) It is ok as it just affects the graphics, not the sound.
I know that Forum Administrators, Lenovo Staff, Community Moderators, Gurus and Volunteered Moderators/Users would be surfing around and looking for new post. Please take a look and leave a post or PM to me, thank you very much.
It is alright if Lenovo don't think that there is any problems regarding the sound in W510. However, I do believe most users/owners of W510 would appreciate if the sound system could be further improved through a better driver or new revision of hardware to something like a T400 standards or something. Some users would spent so much $ just to get all-in-a-box solution and would not want to invest further just for a external card to sacrifice portability and use more $. Finally, I still do believe that W510 audio problems can be resolved.

Peter

Hi ckhordiasma
Thanks for reviving ths old thread. How about trying Dolby drivers? It sounds great and could possibly resolve those issues without going through too much troubleshooting.
The link is under my signature.
Hope it helps!

Lenovo G50-30 RAM Bank Problem

Okay so I purchase an additional 4GB of RAM to stick into the laptop as i've read there are 2 RAM slots available. Ran a Speccy scan - also said 2 memory slots with 1 free memory slot. After taking off the back cover, I see Slot B is already in use with 4GB of RAM. There is a Slot A empty. But there is no bank to stick the RAM into. There is only a bank in Slot B - which would be the slot furtherest north directly on top of Slot A. Now why are there two slots but only one bank? Is there somewhere else that can take the extra RAM? Or so I just return for a 8GB piece of RAM? I've read on numerous sites that this laptop has two slots. But seems only one is capable of having RAM inserted into it?

Hi Geronimofinch,
Welcome to the Forums.
As per the query we understood that you are facing issue with RAM bank in your Lenovo G50-30 laptop.
As per the specification this model has 2 RAM slots, you can refer the manual 2 RAMs can be fitted to this system.
Click here for the manual and refer page number 41.

Audio problem with T61 running windows 7

hello,
After installing windows 7 Enterprise on my T61, I have no sound.
Driver seems to be installed correctly (Device manager), speakers taskbar icon looks & functioning OK, but i can't hear nothing.
I've installed the suggested Vista driver from Lenovo web site, but the problem remains...
I must mention that there was no problem while using Windows 7 RC, the problem started after installing a clean copy of Win 7 pro.
Any suggestions?
Thanks in advance,
Eyal.

I've installed win7 over a dozen times on T61 models and never had a problem. Perhaps if you can provide more information, did you reformat your drive before install, or install overtop an existing windows version? If it helps, all my installations are on a freshly formatted partition. Windows installs working drivers on everything except the ricoh card reader, for that you just need to manually install the vista drivers from device manager and it will work. I then run system update and it installs newer drivers for some of the hardware, but like I said, never had an audio problem.

Lenovo g50-30 sudden crash

Hi everyone! I bought a new lenovo g50-30 (i am not sure about the correct serial but maybe like this or similar: g5030116aus).
My problem is that if start a newly installed offical win 8.1 with basic options after a 20-30 min using the laptop going to black screen, and crashes. Restarting and the win 8.1 loading again. Sometimes it`s stops just after the booting, sometimes after 5 minute using win 8.1. One time I`d like to use the music player with headphones and the OS stopped and the headphones gave me a scratching, annoying noise.
I tried with an my old win 7 OS from my old laptop (yes I know should install a new but I hadn`t much time). Same problem, especially if tried to run videogames. I installed the basic drivers like amd vga driver, lan and wlan driver etc, so the win 7 worked fine. But I started a R6V2 (rainbow six vegas 2) and stopped after starting. Second time stopped after I quited from a the game.My question: Have anyone same problem and could give good solution to fix the problem?
Second: Could be a problem, that I laying in my bed, and moving my laptop then it crashes because of denting the inner parts?
Sorry for my english I am not good at that. Thx for the 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

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.

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 G50-30 stuck at lenovo logo and cant even enter bios

Hello
I yust got my lenovo G50-30 and wanted to install win 7 on it. after the first BsoD I went to bios and changed the AHCI to legacy mode. Got the same BsoD. After that I changed the Os mode from win 8 to win 7 ... loaded the factory default settings and putted from AHCI to legacy mode again.
After that the laptop turns on, but it stucks at lenovo logo. I cant access the bios anymore to make any other changes. If I insert a win7 instalation disc, it start to spin but with no sucess. also cant acess the boot options anymore.
Any help greatly apreciated

I suggest removing battery and AC, holding the power button for more than 15 seconds to reset the BIOS back to default settings then see if the issue remains.
Make sure to post the results.
Good luck.

sorry for the late reply, here's the things you can try , try rolling back the driver or you can access the registry to adjust some values here's the step:
1- install latest driver of your graphic card
2- This step will fix the problem:
3 go to registery by regedit and change the value to 0xf048
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]
"FeatureTestControl"=dword:0000f048
OR
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001]
