ThinkPad R40 with no sound

My R40 does not have sound. In device manager all drivers are installed for the sound card. Sound would play through headphone jack but not copmuter speakers. I attached docking station and could still use headphones off of it. When going into the system speaker in device manager / system devises it says that the system speakers drive is not installed. I have gone to Lenovo website and downloaded and installed the drivers. Still no luck. Now my headphones wont play any sound. I have checked all the other basic stuff. Sound turned up, media player turned up. Is there something I am missing?? Please help!!

Hello, go to the website, and type in your model number. The page will display all the hardware. Choose the audio, and download it to your desktop. Once finished execute it, and it will go to your main drive,(mine is C:driverswin folder). Now open up control panel, go to systems, hardware tab, and device manager. Right click on the audio, and click update driver. The wizard will open, and ask if you want to connect to the internet, choose not this time, and next. The next windows that pops up, make sure you choose install from a specific location, then click on browse, and go to the drive where the driver is installed. This shouls sodve your problem. The same goes for the ethernet, video, modem, and many other deivces. I hope this helps.

Lost wireless - Ibm thinkpad r40

haha worrying isnt it...
after reinstallation of windows no drivers for blutooth , wireless quite often modem and same vga,
windows by default does not install because need specific software ...(drivers)
what you need to do is first of all find out what wifi it is ; like wlan400 e.g.
you then need to download and install the driver for it .as soon as the driver is present windows will detect and install device,
look in device manager for devices with no drivers intalled.
same precedure for each device.

Ibm thinkpad r40 windows xp-pro after formatting and re-installing the system, all updates and SPs downloaded and installed, the wireless "disappeared"! the radio led wouldn't lit, in the connection list...

if drivers installed device is looking for wifi manager which is the software package for wifi.
you can goto control panel open administrative tools select sevices and scroll to wireless zero config and press start.
this will then use windows settings.done

No Sound On My IBM R40

What I ask myself is, If sound and wireless are not working - what else might not be ok until you find out later, when you have documents and applications installed?

I would reset the R40 to factory settings right away. Hopefully that person hasn't removed the hidden partition...
You can check that by going into your Device Manager (Right-click "My Computer->Manage->Disk Management) and see if you see a Fat32 partition usually called "ServiceV001".

Restart your notebook and hit the blue button at the ThinkPad splash screen. A wizzard will lead you through the process.

Rescue and recovery will restore your laptop to factory state. It has an image of their default installation with all the software, settings, and drivers.

After you're done, you have to update the drivers to the newest versions. Look in you start menu and you will see an entry called either "IBM" or "ThinkPad" with a sub-menu that contains the software to update your computer.

If you want to manually update your drivers, go here, fill out the form and follow the prompts. (You will find the necessary information on the sticker on the bottom of your laptop).
It will get you to the right page.

If you have any questions, come back here and leave a comment. I am happy to help!

Good luck!

is the windows cd for ibm specifically?
if not then you will need:
a sound card driver (optional)
a graphics card driver (optional)
a cd rom driver (maybe)
drivers for usb ports (optional)
and any other drives/ input devices on your laptop will need drivers.
when formatting bear this in mind. All data will be lost! proceed knowingly and with caution. one mess up will land you in problems up to your shoulders!
i recommend finding out how to do it safely

IBM T40 thinkpad

It can be that the sound card driver is not properly installed. You may check that on the Device Manager of your laptop. If it's not properly installed, it needs to be uninstalled from the Device Manager and reinstall it by using the driver installation CD that came with your laptop or you may download it on this link.

The link already contains the instructions on how to install the driver of the adapter.

have you tried going into your master volume contro properties and turned everything up there. If you double click on your volume control near the time and go to properties you'll find all the controls there. Let me know if that works for you.

No Sound on R40

your system may be designed this way. But you can refer to its manuals or online support to find out whether your PC really supports audio. Another thing is that the socket in your laptop may have lost its connection to the motherboard. But first thing you should check is that whether your operating system detects any new hardware. If yes just find the driver for it. You can download drivers from the manufacturer's website.
