Question about IBM ThinkPad R40 2722 Notebook

1 Answer

No Sound on R40

When plugged into a docking station there is sound. That leads me to believe that there is nothing wrong with the sound card just as device manager shows. But the speakers and headphone jack do not produce any sound from the laptop itself. When in system devices in the device manager the system speakers show no driver. I have tried every sound drive and still no luck. I went into bios but there is nothing pertaining to sound.

Re: 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.

How can i update dell dock?

A docking station is an extension or addition of ports for a laptop computer. Once the portable computer is docked, you can access the docking station's ports, such as PS/2 or USB 2.0 ports, through your computer. Some docking stations have monitors that you can connect your computer to, placing your video on an external screen so you can turn off your computer's monitor and conserve some of your computer's energy. All Dell docking stations will have the same general troubleshooting steps.

Plug your laptop's power adapter into the docking station and dock your laptop onto/into the docking station. If there is no power going to your laptop from the docking station but it works when the power adapter is plugged into the wall, the docking station is bad and needs to be replaced. Plug your power adapter into the docking station and dock your laptop onto/into the docking station. If power goes on but your computer doesn't recognizes accessories such as a USB mouse--plugged into the docking station, try a different port on the station. If it works in a different port, the previous USB port is burned out. Plug your power adapter into the docking station and dock your laptop onto/into the docking station. If power is going through the docking station but no accessories are being recognized, you might have a corrupted docking profile. Undock the computer and dock it again once it has fully started up to reset the docking profile. Plug your power adapter into the docking station and dock your laptop onto/into the docking station. If you have an external monitor and it is not working, completely close the lid on the laptop so the image will move to the external monitor. Plug your power adapter into the docking station and dock your laptop onto/into the docking station. If power is going through the docking station but no accessories are being recognized and resetting the docking profile fails, update all drivers through Dell's support website and then re-dock the computer. Some of the software that runs the hardware may have become corrupted. Hope this helps

Dock station for hp pavilion

You need to check the plug that plugs into the laptop to determine that you don't have a faulty lead or plug. Test it with a multimeter and wriggle the plug to see if the voltage reading remains steady. If it doesn't then it could be the lead and this is easily repaired.
You may be able to borrow an adapter to test your laptop's connector.
If you determine the fault is with the laptop then problem is most likely the connector socket on the laptop, it most likely need re-soldering onto the motherboard, or needs to be replaced. This requires the laptop to be dismantled completely.

A docking station would solve your problem because the docking station has its own power connector and you plug the existing power adapter into the docking station.
My HP is connected to a docking station, the other advantage is that the docking station has several more ports than the laptop which is useful.

D630 docked , ext mouse & kybd not responding

If the docking station has power:

Make sure power is off for both the laptop and the docking station. Plug your keyboard and mouse into the docking station. Dock the D630 to the docking station and then power on docking station. This should then turn on your D630. Your D630 should detect the keyboard and mouse.

If the docking station has no power:

Verify that the power cord, AC adaptor, etc. is plugged in. If the items listed seem to be in order,
there may be a problem with the power going into the docking station. (AC adaptor?) will have the specific details for your D630 and your docking station, et al.

Please let me know if you have success in this.

Fix video?


If your video was working fine before then it might be a corrupted file driver of your docking station. No need to worry with your computer because it is not your computer causes the problem. It is your docking station.

You may try reinstalling your docking station software using the cd that came with it.You need to connect your system to your docking station when reinstalling the software. if the issue persist after installing the software. Please check if your docking station still in warranty and check their part replacement policy.

Keep me posted.
