As the title states, the built-in mic on my Toshiba Satellite P305-S89151 Laptop does not work after upgrading to Windows 7 today. I did a Google search and saw that somene else with a TOshiba laptop was hving the same problems that I am, which brought me to here. Someone responded to his thread with a bunch of questions, so I will post my answer to those questions here: 1. The Make and Model of the Motherboard No idea, but this is a link to its specs: Satellite P305-S89151 2. Make and Model of Sound card if it is an Add-on card It is a built in card. 3. Operating system name Bit and Build or Version? Windows 7 64-bit 4. Is that a New installation? Yes, a clean install. 5. Brand name of Headset or Stand alone Mic used It is the built-in mic next to the cam on the top of the screen. But, I tied pulling in my Logitec headset into the mic jack and it does not work either. 6. Are there speakers in this PC > details harman/kardonÃ‚Â® stereo speakers, Headphone jack (stereo), S/P DIF output port (shared with headphone port), Microphone jack (mono), Built-in microphone 7. Was mic working before in this PC using another OS? What OS? Does the tested MIC work in another System? Yes, I was using it not even 2 hours prior with Vista 64-bit. It is built-in...can't use it with another system. 8. Has anybody worked inside the PC ( hardware troubleshoot)before problem began. No, I just bought this laptop two weeks ago. I rely on camming to talk with my friends and family back home as I am stationed overseas. Does anyone have any idea how I can get my mic back up and running? Thank you in advance!
