I have bought this notebook 3 months ago and since then i'm experiencing sound issues. Today the sound decided not to work and i cannot hear a single thing. If i put on external speakers or headphones, i can hear the sound. Can anyone help?

I'm actually regretting ever buying this model and i do not know why i bought this laptop.

A:Satellite C850-F211 - Sound Issues

> If i put on external speakers or headphones, i can hear the sound. Can anyone help?

Looks to me like internal speaker malfunction.

But did you check the sound settings?
Go to control panel -> sound -> playback tab and check the available devices.
Are speakers listed in this tab? And if YES, are the speakers marked as default device?

Additionally it?s worth to reinstall the sound driver.
I guess its Realtek sound card.

So uninstall the Realtek sound driver from (control panel -> programs & features -> Realtek High definition audio driver).
Go also to device manager and delete the device (Intel display audio) from the area:
Audio, video, game controller.
Do the same in area System devices: here delete the entry: high definition audio controller.

So finally reboot the unit.
After new reboot, windows system should recognize the deleted devices automatically.
Wait until the devices have been installed. Now test the sound.
If you would not get any sound via speakers nor via headphones, install the Realtek sound driver.

But if this does not help, I would recommend contacting the service provider to check the speakers

I have a Satellite C850-101 running Windows 7 Home Premium SP1

When I turn the laptop back on from Shut Down, no sound comes from the speakers or from the headphones.

If I restart the laptop the speakers and headphones work fine.

So every time I turn my laptop on, the speakers do not work and they will only function again when I restart..

A little investigation of this problem shows the following...

Whenever I turn my laptop on and go to Control Panel->Hardware and Sound->Manage Audio Devices I see two items:

1) "Speakers - High Definition Audio Device - Not plugged in" with a greyed out speaker icon with a red arrow.

2) "Digital Audio (S/PDIF) - High Definition Audio Device - Default device" with a coloured external amplifier icon (looks a bit like a DVD player) with a green tick. There is an audio level icon next to it which does show sound whenever sound is played on my laptop, but no sound is audible either through my speakers or headphones. I believe this is for the HDMI connection

Whenever I subsequently reboot my laptop and go to Control Panel->Hardware and Sound->Manage Audio Devices I see one item:
"Speakers - Realtek High Definition Audio - Default Device" with a coloured speaker icon and a green tick. The sound works perfectly fine.

I have uninstalled the sound drivers, reinstalled them from the Toshiba website and also downloaded and installed the latest drivers from Realtek.

Hey guys.

My laptop is a TOSHIBA Satellite L775 (Windows 7) and for quite a while now Iíve been having Ďstutteringí problems with the sound. If Iím watching a youtube video (or listening to music files on my hard drive) occasionally the sound lags. It wasnít too much of a problem at first but itís happening quite often now and is incredibly annoying/worrying.

Iíve checked out a lot of forums and questions online regarding similar problems, so far I have disabled and replaced my sound driver (although there are like 5 NVIDIA sound drivers I did not have the option to uninstall), disabled a few programs/services using the msconfig (although I donít think its related to the processor or processes, my laptop has 4GB of RAM and an intel i5 processor, Iíve ran pretty intensive games on it in the past with no problems so canít see it lagging over music).

I tried downloading a new Ďatherosí network driver, I didnít uninstall the current one as Iím in the middle of revision and donít want to cut myself off from the internet by mistake. I simply downloaded the replacement driver and ran the install wizard for it, the problem still wasnít fixed.

It might be worth nothing that after I disabled a few programs to see if it was the RAM that the problem seemed to get worse, with massive hangs in the audio. The first time I remember seeing this was almost a year ago, I was playing Crysis 2 and the game/sound crashed. Occasionally after this the stuttering would occur whils... Read more

Recently I've been having some problems playing back any sort of media.  At regular intervals the audio will freeze/skip for a second and make a loud buzzing noise, then resume.  This happens with both music and streaming videos. If I'm watching a video, the screen will freeze for a second, buzz, then resume.

After my computer did its usual updates, I've noticed a sound issue whenever I've been trying to play games/watch videos. At regular intervals the audio will freeze/skip for a second and make a loud grinding noise, then resume. This happens with music, streaming videos, games, pretty much everything. If I'm watching a video or playing a game, the screen will freeze for a second, then resume.

I'm using a Dell Inspiron N4110 laptop with Windows 7

I assume I need to install a new driver or something, but I am pretty computer illiterate and don't exactly know what I need/where I need to get it from/how to figure out what I need.

Was hoping someone could help here.

A:Audio buzzing/stuttering during videos/games

Since the screen will "freeze", suggests the sound problems are just a result of whatever is causing the PC to hang up and not directly a sound problem. Thus another forum section would be more applicable than the sound section.

You can run the Resplendence Latency Mon program and that may help, if you can figure it out as it gives you "information overload".

This has been happening for a few months now. The buzzing/stuttering varies and it's quite annoying. It only happens when I watch YouTube videos or just videos in general. I'm not sure if it's a hardware problem or just a driver problem. I have a similar problem as these people: http://en.community.dell.com/support-forums/laptop/f/3517/t/19412524.aspx except that my computer model isn't a Dell. My main browser if Google Chrome if that helps.

I ran DPC Latency Checker and this came up:
Some device drivers on this machine behave bad and will probably cause drop-outs in real-time audio and/or video streams. To isolate the misbehaving driver use Device Manager and disable/re-enable various devices, one at a time. Try network and W-LAN adapters, modems, internal sound devices, USB host controllers, etc.

Hi all,

I'm posting in the Windows forum because the exact source of the issue is unknown. If we come up with a more precise cause I would be happy to move the discussion to the appropriate forum.

The problem is a brief sporadic stuttering or digitization noise (very similar to some elements of dubstep music actually). It sounds like a quarter-second of audio is repeated at high speed and then it goes back to normal. This happens with variable frequency; sometimes once every minute or two, sometimes as long as 45 minutes between occurences. The frequency seems at least partially dependent on the graphical output being used, but it's hard to tell for sure. The problem is quite immersion-breaking, and it extends to all uses (local music, streaming, gaming, movies, everything). I suspect that the entire computer (not just the audio) may be pausing/stuttering along with it, because sound effects never get desynced with video; for example when people are talking in movies their lips never get out of sync with their voices, despite the audio pausing while it stutters.

This problem started about 3 weeks ago, and I had not made any hardware or software changes that I am aware of.

Possible solutions I have already tried, without effect:
New GPU (same model as old one)
New PSU (same model as old one)
Disconnecting HDMI
Running only 2 monitors
Adjust NVIDIA settings for performance not quality
Rolling back GPU drivers twice to different versions, then updating

I have a brand new Inspiron 7560 and I've been having a lot of issues with the audio and video sort of lagging and making a buzzing noise and stuttering, it happens every 15 minutes when watching something or listening to music.
I had this issue and then got the laptop replaced because I had no idea what the issue was. I don't like returning items but it was brand new and cost a lot so I was worried there was a bigger problem. It happened with the first one from the get go but with the replacement it started happening after a few days of use. It started off with static noises every so often roughly within the first say 30 minutes of turning the laptop on, and then it started doing the buzzing and lagging every 15 minutes like the first one I had. I've also noticed a static noise whenever putting the charger in or out.
I had a look on the internet on how to fix it before I got the first one replaced but none of it worked, I've had another look now and came across a thread but it was from 2011 so thought the fix may be outdated now. I thought my best bet was to just come straight here to see if anyone could help.
I'm really hoping this is a known issue and it's easy to remedy as I really don't want to return this one after already returning one. I'm sorry I haven't got much information about the issue, but I hope someone will be able to help me. If you need anything else I will try my best to answer any questions.
Thanks very much

A:Audio and Video make buzzing noise/stuttering every 15 minutes

Different folks have problems for different reasons.  I would suggest you open at least Task Manager to watch the performance on the system to see if anything pops up every 15 minutes which is using resources.
Keep an eye on Processor speed and utilization.  Also the drive usage.  I can't think of anything which goes on a 15 minute time interval, but possibly some setting you have set up such as checking for mail..
Using Resource Monitor would be even better,  but the software/browser you are using could also be involved.

Ok, so I've tried my best. I realise there are a few nice things about Win8 but like a ginger stepchild I just can't accept it as part of my life. I've had the laptop for 6 months now and regardless of changes I make I just keep on coming back to the fact I am trying to force Win 8 into the way Win 7 works which is daft when Win 7 is available. The only real reason I have held back is that Win 8 was the pre-installed OS (Toshiba should really review that decision, it's a horrible OS for anything other than casual tablet use and effectively cripples their hardware). However the time has come, I simply can't continue. Win7 must return to the throne.

Going Forward:

Anyway, preamble aside, I have a couple of questions regarding the "downgrade". First off I have used the Toshiba 'Recovery Media Creator' to create the backup disks (which I presume return the laptop to the "out of the box" state) and backed up any important data. I have Windows 7 on a bootable USB stick (A legal copy too - oh, how decadent!).

I believe I need to set the _Secure Boot_ to *Disabled* and the _Boot Mode_ to *CSM Boot* in order for my bootable USB stick to be detected. I have read several pages about this and some suggest I will need some sort of SATA drivers on the stick too. Can someone confirm is this is true or not? If it is true, where do I get them from (URL if poss?) and where do I put them on the stick (root? Will it ask for a location?).

Still Having problem with a satellite C850-1KN. I have the recovery discs but thought I would try and recover from the hard drive. This is what happens :
Start up with F12 pressed until See Toshiba display. Get to boot menu, go to HDD recovery, choose language, go to Troubleshoot. Choose option " refresh PC , press next , choose to start in Win 8.1 and get message "drive where windows is stored i9s locked . Unlock drive and try again ". Any ideas how to unlock the drive as the computer will not start up unless I use F12.
If I use option "toshiba maintenance utility " and win 8.1 as target operating system I get an invitation to choose either 1 ) delete all dat and partitions from the hard disc or 2) delete all partitions and overwrite all sectors on hard disc.

What will these do to my computer ? would I end up with a useless piece of junk or will the operating systems still be there. There are other options
such as "reset your PC" when all personal files and applications will be removed, and PC settings will be reset to their defaults . What will be left on the computer.

I have not tried from revery discs yet and wonder if this is the best option.

A:Windows 7 installation on Satellite C850

Preinstalled versions of Windows 8 uses UEFI instead of a BIOS so you cannot boot from CD's or USB keys that expect a boot sector.

However you can enable BIOS emulation:

Go into the BIOS and then to the Security Tab, disable Secure Boot.

Then go into the Advanced Tab then System Configuration, change the Boot Mode to CSM.

You will need to remove the CD/DVD drive firstly.
Then you will need to use a plastic stick to push the back of keyboard from the slot in ODD housing. The keyboard should be pushed until the corner raises upon top case surface.
After that using the same plastic pry slice to insert the gap between keyboard and top case, then pry keyboard edges carefully until all latches are unlocked.

My Satellite Pro C850 was purchased in March 2013. By December 2015 the battery would not hold a charge long enough. In December 2015 I bought a new genuine Toshiba battery from a reputable company cclonline.com. Now only 3 months later my laptop shows a red cross over the battery indicator. Unplugging the power lead still allows me to use the laptop but seemingly randomly the laptop hibernates/shuts down without displaying the reason. After this happens I have to plug the power lead in again to restart the laptop, although I can unplug it again later without the laptop dying. For purely personal reasons my power options are set to Never for all choices. All this does not stop me using the laptop, but it can be annoying when the laptop suddenly saves everything and shuts down.

Hi all

For some reason, neither my internal nor external DVD writers will burn DVDs. My internal DVD-RW is a tsstcorp cddvdw sn-208ab. Th external DVD-RW is a tsstcorp cddvdw se-208db.

For a while I could burn a DVD by using "Fix it", but then I'd have to reboot, use "Fix it" again, but now that doesn't work at all.

Sometimes there is one driver shown (C:\WINDOWS\system32\DRIVERS\cdrom.sys) and sometimes there is a 2nd driver (C:\WINDOWS\system32\DRIVERS\GEARAspiWDM.sys).

I've tried uninstalling the DVD-RW drives, and rebooting.

I installed the Gear driver update, but then I couldn't find it in its location.

About 6 months ago, I had similar problems and fixed it by deleting registry keys (upperfilters & lowerfilters), and that fixed the problem at the time.

Maybe I need those keys back? One site recommended adding an UpperFilter within the same folder, containing the text "GEARAspiWDM" & rebooting, which SOMETIMES allows me to burn ONE disc, then the reg key is gone.

I tried uninstalling the most recent Windows update, but it made no difference.

I have used a range of burning software- doesn't seem to make a difference.

Any suggestions would be appreciated

I have a Satellite C850-13c with the b820 celeron cpu.I bought a core i5 2450m to upgrade but after installing the new cpu the laptop turns off every time after exactly 30 minutes.

The problem happens in bios mode also.In the first 30 mins the laptop works perfectly but it just shut's down without warning.

Aparently other people had the exact same problem with this laptop model , even with a core i3 cpu upgrade.

Things i tried so far:

- Cooling system check - all ok , temp doesn't go above 40c
- Bios updated to the latest version
- Disabled all the core capabilities of the cpu from bios
- Bios battery reset
- Tried it with AC adapter only, battery only , same result.

Does this model just can't handle a bigger cpu ?
Please help :(

A:Satellite C850-13C turns off after CPU upgrade

Generally speaking CPU upgrade is not supported so with such issue you are on your own and every hardware exchange is on your risk only.

Problem is that Toshiba doesn?t any precise info about CPU upgrade and functionality with different CPUs. Due to specific design there is risk of overheating.
In your case it is interesting that notebook switched off after exact after 30 min.

Unfortunately I cannot help you with this but this case is very interesting ad I will continue to follow discussion. Let?s see what other people will write about that.

Hi all,

Recently purchased a Toshiba C850 laptop for my wife.
Working in I.T the first thing i did was run windows update, it prompts updates are available and starts downloading.

However, it just sits forever on 0%, I have checked the download folder within software distribution and this fills up with the updates, however the windows update screen never changes.
I have ran updates on other win 8 machines on the same network so I know it is not an internet issue.
Have reset the pc using the reset my pc function within windows 8, tried again and still the same.
Ran the fix windows update files from microsoft support....still the same.

Even if i choose just one update to download and install it just sticks on 0%.
Cleared the contents of the software dist\download folder. started the update again and this folder begins to fill, but even after leaving for 24hours its still on 0%

Have reset all windows update components, checked nothing is using the same port as the windows update server and still no luck.

One thing i have noticed is that if i try and stop the windows update service then the whole laptop grinds to a halt, it will start to stop, however then hang on the stopping screen.

The only was to get it to stop fully is to end the svchost.exe which has other critical system processes associated to the specific process which is running.

Any ideas at all as i am left with this laptop which just will not update despite being set back to factory setting... Read more
