Hi there, hope that someone could help me. I am using Thinkpad R61.
Theproblem occurs when i am using the units with the battery that
iswithout the power adapter. Somehow, everything's run smoothly
duringthe boot up. The problem will start when entering windows vista.
Itkeeps making the hissing sound like beeping all the way. But, when
iplug in the power adapter, the sound will dissappear. I already
tookthe machine to the IBM service centre, they changed the motherboard
andthere is still the sound. They also informed me that they could
notfigure out for the problem. Thank you.

I see that you are having issue with your taskbar flickering as you mentioned in the notes.
I would be more than glad to assist you regarding your concern.
>Try to reinstall your Video Drivers on the machine or poassibly update the Video drivers.
>Try chagning the resoltion on your system try setting it to a resolution that is lower than what you actually have and see if the flickering will still be occuring.
>Also try to boot into the BIOS of the machine to see if the Flickering occurs in BIOS as well, to boot into BIOS upon powering the machine keep on tapping F1 till you get a blue screen saying phoenix BIOS as long as the word BIOS is there you are in the right page. just check if the flickering happens there, if it does then the issue is not software but most likely hardware it can be the LCD itself or the Cable conenction of the LCD to the Video on the motherboard.
>if the flickering is present in BIOS most likely you will need to have the system serviced for proper repairs and diagnostics.
What do you mean it stopped working? No sound at all?
Please try the following:
1. Please make sure the sound is not set to mute. Try to adjust the sound volume.
2. Reinstall the audio driver. You can do this using the drivers disc that came with the computer or you can download the audio driver from the computer manufacturer's website: http://support.lenovo.com.
3. Try to connect an external speakers or headset. If you can hear sound on an external speakers or headset then the internal speakers of your laptop is already defective.
This issue will occur if the Computer speakers are not to the default Audio Device. Please right click on the Sound icon on the right corner of the Taskbar (System Trey) and select the "Playback Devices". After that, please right click on the "Speaker/Headphones" to set them as the default Audio Device. This should enable the Computer speaker and sound should work correctly.
If the above steps did not resolve the issue, you may need to re-install the Audio Driver in the Computer to resolve the issue. You can download the Audio Driver using the below link.

All you have to do is enter the serial no of your laptop and the model and will give you the latest drivers and softwares available for your laptop. Here's the website consumersupport.lenovo.com.
