I have recently updated my lenovo t43 with sp3 since than have no sound
please help
Open up Device Manager (Start > Run > type: devmgmt.msc) and look for items with a red or yellow icon. This means there is a problem with the device driver. In which case, you should go to the computer manufacturer's website and download then install the proper drivers. Apologies if I don't respond to your reply immediately. I don't check this site daily.
