| 1374642 | 2014-05-10 22:39:00 | Hi, I am looking at a friends laptop which about 50% of the time when started or rebooted has no sound. I have attached two pictures one when sound is ok and the other when there is no sound. Does anyone know what is happening here? I thought the speakers might have a loose connection but during reboots I haven't moved the laptop or the lid. Thanks, asdex |

| 1374645 | 2014-05-11 00:14:00 | Go into the BIOS and make sure the onboard Audio hasn't been disabled. Have a read of the following article - could have been a driver update as well ( read all the comments for other solutions) social.technet.microsoft.com (http:) | wainuitech (129) | ||
| 1374646 | 2014-05-11 02:20:00 | Hi, I have looked in the BIOS but no sound card options. Also this is intermittent so do't think its a BIOS setting. I have rolled back the sound card driver and updated it plus made sure the laptop is all up to date for Win7. There are no cables plugged in, just the laptop speakers which I'm sure will be permanently connected. Thanks, |

| 1374648 | 2014-05-11 02:57:00 | Some laptops have an SPDIF connection in the headphone jack. When the audio isn't working check and see if there is a red light coming out of the headphone jack. If there is then you need to put some contact cleaner on a 3.5mm plug (say on a set of headphones) and put it in and out of the socket 20-30 times. | Alex B (15479) | ||
| 1374649 | 2014-05-11 08:48:00 | Hi, there isn't any red light in the ear plug jack. There happened to be a BIOS upgrade from 3.6 to 3.7 so I have done that. Still no sound sometimes. The sound seems more likely to be gone when I do a shutdown and then start up rather than a reboot. When the sound is gone on the speakers, It also is off on the ear phones too so not sure what to do next. Thanks, |

| 1374650 | 2014-05-11 09:12:00 | One thing you can try -- Boot the Laptop from a bootable OS, something like Linux -- mint, Ubuntu, Puppy, etc. You may need to do this several times, if it boots each time OK from the CD and has sound then the problem is software related. The only problem with booting from a Linux CD is it may not pick up the audio in the first place. If its hardware -- Well depends on how much you want to spend on getting it fixed. A faulty circuit or joint on the motherboard generally means a new board, as trying to locate and fix it may cost more than a replacement. First you need to sort out is it software or hardware. I have looked in the BIOS but no sound card options Most motherboards will have an option, just not always in the obvious place, have you looked in EVERY setting ? can be under PCI integrated devices etc. All depends on the type of BIOS. |
