Switchable Graphics on Satellite L855-10X

Question: Switchable Graphics on Satellite L855-10X

i have a Toshiba Satellite L855-10X (i7 3610qm/6GB DDR3/AMD 7670m 2Go) ,everyone knows that intel 3rd generation processors have a built-in graphic card, the intel 4000HD which is less powerful than the AMD 7670m but which have the advantage to save power when you're on battery mode.

My problem is that i'm not able to use this card and i can't even see it in the device manager as the system does not detect it. However, after some searching on the net i found an answer : it seems that it is TOSHIBA BAD IDEA to disable the intel 4000 HD from the bios and worse you can't even switch it on yourself from the bios because some menus are locked. Also there is a mystery in all that case !!!

Why would TOSHIBA support you with the intel display driver in their site when it's useless, because when you try to install it an error message shows up telling that the system does not meet the minimum requirements. If anyone is facing the same problem or found a way to activate the intel 4000 HD even by installing a modded bios driver just reply to me please.

Preferred Solution: Switchable Graphics on Satellite L855-10X

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

> when you try to install it an error message shows up telling that the system does not meet the minimum requirements.
You are not able to install the Intel driver via setup.ext or install.exe because the Toshiba notebooks uses Toshiba modified graphic card drivers.
If you want to install the compatible and right Intel driver from Intel page you have to do that via device manager.
Do you know this procedure?

In device manager you have to choose graphic card, then have to update the driver using the advanced procedure.
This helps you to choose the driver folder? the driver folder can be created on the desktop and should contain the Intel driver files downloaded from Intel page.

Hello every body,

Fistly sorry for my bad english,

I have Toshiba satellite L855-10w with a AMD radeon hd 7670m.

I'm wondering, why i can't use AMD Dynamic Switchable and also why i can't find Intel HD 4000 that must be integrated witch Intel I7 3610qm in my system configuration?

What do you think about this?

Thank you very much

Answer:Satellite L855-10W - cannot use AMD Dynamic Switchable


I read somewhere in the internet that the AMD Dynamic Switchable feature is not supported on Toshiba notebooks.
It seems that only nVidia Optimus Technology (for notebooks with nVidia graphic chip) is supported.

Hi there everyone!

I would really like to know if Toshiba is planning (I hope so!) to release in the near future a Bios update for the Satellite L650 that will enable the switch between the discrete graphic card and the one included in the die of the CPU (i5 series).

The so called "Switchable Graphics" is already available on some Acer's notebook (Timeline X), some Asus and other brands, and I really would like to see it implemented on the Toshiba notebooks as it will increase the battery life (double it or even more) and make everything more efficient and "greener".

The Toshiba L650 I'm talking about should have everything needed for this purpose: chipset Calpella HM55, i5 and 5650 mobility, (and Windows 7).
Why not take advantage of something that can be used even on this notebook?

Thanks a bunch. :)

EDIT: my model is the Toshiba L650-16W. Here are the specs:

Answer:Switchable graphics on Satellite L650

Hi Dany

This is user-to-user forum and nobody here knows for sure what Toshiba will do in the future.
As far as I know Toshiba has offered BIOS updates for all models in the past so I believe this will happen for your notebook model too but what will be new in this BIOS update is not easy to say.

So, you must wait and see what will happen next months.

Hello Toshiba Forum,

I am owner of a Toshiba Satellite Pro A 300 PSAGDA-02000R.
My question is, if the laptop supports Hybrid Switchable Graphics?
I was searching the Internet for days, but i haven't found a suitable answer for my question.
I found this brochure: with specs of the Laptop.
I have found this offer with a Satellite Pro A 300 with a different model number providing Switchable Graphics:

Thanks for answers...

Answer:Satellite Pro A300 - Does it has switchable graphics?

hi -Piliphus-,
another one who believes in the easter bunny.... commercials...

after doing some investigation and searching a wiki...:
+"Hybrid Switchable Graphics"+ and +"intel"+ some facts came to light:

one is +SLI+ which make possible to connenct 2 graficcards
and the other +Intel Graphics Media Accelerator+ which is located IN the northbridge to accelerate accessing ram and grafics

and what do you want to do with that +"Hybrid Switchable Graphics"+?

and yes your notebook has both of this components...
and no it wont give you extra time or making you a coffee or brings you back in time...

it's just a state of the art video and grafics handling - no more no less...

Unfortunately, at this moment the R series doesn't offer a switchable graphics option between the integrated graphics chipset (Intel HD Graphics 3000) and the dedicated ATI 6450M.

Myself I have a R850-10V model with an i5-2410M and there is no option in BIOS for such a selection, which would help a lot to increase the battery life by using only the integrated graphics for example.
Could we see in the future a bios upgrade which would enable this integrated graphics?

It's a shame because all the other important producers (HP, Lenovo, Acer) which use ATI 6450/6470/6490M solution for integrated graphics, updated their bios in order to allow a switchable graphics option.

Thank you.

Just bought brand new Toshiba Satellite L750D - AMD A8-3500M with AMD Radeon HD 6620G today

Setting up but have issue where graphic properties ask to configure switchable graphics for certain apps such as skype. When I select high performance and click update it goes back to unassigned. And this continues to happen for other apps as well

What is wrong?

I would suggest checking whether you have the latest AMD Radeon drivers and software for your laptop. If you have the lastest you can try reinstalling it and see if it works after that.

I have Thinkpad T410 (type 2522) ,its dual graphics nvidia 3100 and intel.But I want to know if T410 have driver with switchable graphics or no like in my old Thinkpad T400.anyone can help me???

Answer:Graphics driver and BIOS setting for ThinkPad T410 systems with switchable graphics???

Hey there donnytax and welcome to the forums!
According to the PSRef (page 308) for the T410 (2522), the machine was configured with the NVIDIA Optimus Technology. This technology auto-switches between discrete(NVIDIA NVS 3100M) and integrated graphics(Intel HD Graphics in processor), depending on task your are completing at the time.
You should be able to find this option in your BIOS -> Config -> Display, if it is an available option to you. The specific line you will be looking for will be something like "OS Detection for Switchable Graphics".
Currently, in the driver matrix, there are drivers for the Optimus Technology.
Note: Some T410(2522) came as a discrete only, and did not have the Optimus Option. Following the 2522 on the back of your machine on the tag, what are the next 3 alphanumerical characters?
I hope this helps.

Hey guys. I've had this laptop for about 2 years now, and at first it ran pretty much any game on high settings. Then one day my framerate dropped off out of the blue. Games I used to play on High (Star Wars The Old Republic, and Minecraft) I'd get a solid 50-60fps. Now I'm lucky if I get 10fps. Even League Of Legends, which isnt so graphic intensive, only runs at about 25fps. What's the deall? I've tried updated drivers, direct x, and whatever else needed to keep my system current. I've tried both methods of switchable graphics. No change. What's even weirder is that sometimes while trying to play swtor my card seems to "wake up" and runs smooth as silk. Perfect framerate, looks great....then back down to horrible. Any suggestions of what I might be able to try or what the issue could be? As far as I can remember this happend overnight without any warning signs.

I have HP Pavilion dv7 Notebook with switchable graphics bought year 2012.
I have had almost all the time problems with those 2 graphics drivers (AMD HD 6770 and Intel HD Graphics 3000)
HP do not have made new switchable graphics drivers (for example for Windows 7) for years and everybody can see that internet is full of very disappointed and frustrated comments of that!
Now when I updated my Windows 7 to Windows 10 It became one big problem caused by switchable graphics. Booting time became very long - terrible long!
It came black screen that lasted 1 minute 25 seconds!
I tested it and took those graphics driver away and then - that black screen was only 2-5 seconds.
I discussed with Microsoft technician (in Finland) and he said that they put only the basic drivers to Windows 10 and this time it do not work normally.
HP is responsible for those special correct drivers!
I have not found correct drivers from HP-support sites (Have any other??)

But there is one good way to solve that problem!
I installed from (Catalyst 15.7 WHQL UnifL v1.2) graphics drivers

Downloads -

And everything works fine - that blank screen is now only 3-5 seconds and switchable graphics works normally!
(First install Intel driver and then AMD driver and that is all!)

Answer:Problems with HP switchable graphics - graphics drivers made slow boot

Driver support by PC assemblers often is poor: While the hardware manufacturer himself still does offer updates, the assembler often does not update his customized drivers.

Intel offers a current driver for that graphics card: Intel Download Center
As far as I can tell, using that driver, the Intel HD 3000 graphics card is working correctly under Windows 10. (Although Intel marked this driver as "for Windows 8.1" and not for Windows 10, it is in fact working better for me under Windows 10, than it did under Windows 8.1. Using this driver, I had small glitches in Windows 8.1, which I do not have with the same driver in Windows 10.)

Hi there.My issue is related to my switchable graphics option. I have an Intel hd 3000 and an AMD radeon (I'm not sure of the exact model as I can't search for it as my machine is currently stuck in a system restore loop so I'm having ti use my phone right now).There is one game I use regularly which, for some reason or another, is incompatible with my Intel graphics chip so I had previously used the right click on my desktop menu where I would select switchable graphics, and then manually allocate that particular game to my AMD chip rather than my Intel one.When the game updated yesterday, it reverted back to my Intel chip for some reason and when I right clicked on my desktop, the option to change it had disappeared.

Hey Guys, i got an new Lenovo Edge e520 with a switchable graphic solution using Intel HD3000 and ATI HD 6630M. When I activate both graphic cards in bios, all runs well on Windows. The Lenovo Power Manager displays a battery running time of around 5 hours. When I disable the switchable graphics in bios and set integrated graphics only, the battery running time on windows drops to 2,45 hours. But how can that be ? It's only using the low power integrated device ? Before you ask the question, yes need the only integrated graphics solution for Linux, where switchable graphics do not work.

Answer:Lenovo e520 - Switchable Graphics Problem - Low Battery when using integrated graphics only

Hi, Me and a few other owners of an edge 520 have an issue with switchable graphics. In our case, the ATI card doesn't work, even with BIOS on switchable graphics. See thread : I don't know if this is related to your problem. Are you sure that the ATI is active when you set switchable graphics on ? Did you test it on a demanding 3D application ? Do you have switchable graphics as an option in the menu of the power management icon in the icon bar ? From your experience and ours, it is as if the BIOS settings switchable/integrated have been switched !

T410s is a good model, but I hope that Lenovo is able to provide a good reason if you can upgrade or not to upgrade.

Answer:T410s switchable graphics models able to upgrade to optimus graphics ?

If it didn't come with Optimus, then you probably can't upgrade it. Optimus configuration requires both a mixture of hardware and software. The hardware has to be internally wired to support it, and depending on the model of your T410s it either shipped with Switchable graphics support or Optimus graphics support. Since this is a hardware limitation, you aren't going to be able to upgrade.

So, I went on the Switchable Graphics options. I put Counterstrike Global Offensive on the "High Performance" option. Which means it should be on my AMD Radeon R9 M275 2GB, right? I tried monitoring what GPU it uses as well, but that's bugged and won't tell me. Anyways, on low settings, CS:GO lags to hell! What? This is a quad core i7 processor with a 2 GB card. Why can't I play CS:GO without lag. I'm talking about below 20 FPS. Even though it SAYS Optimum or High Performance, it seems to be running off of the Intel HD graphics. Thanks.

Answer:[Y40] Switchable Graphics seems to not be working. Every game is running on the Intel HD graphics?

Hello all, I wonder if anyone found working drivers to switch graphics between the integrated and the ATI one.  The problem I have is that I once installed the Beta drivers for Win 7 and it all worked fine except that I did not get the on screen displays for brightness and the mute key did not work (though volume keys worked) Now, after installing an update for the ATI driver, I got the onscreen displays and the mute key to work but I cant change the brightness when using the ATI graphics. ATI has a beta release for the win 7 os on their website but for the latest they can do they recommend going to the laptop manufacturer's site. At the site I downloaded every possible driver without success (and once I got a blank screen after windows loaded...I had to start in safe mode and remove all ATI drivers to get a display at start up) so I am running now on the integrated graphics card and it works fine but if I switch to the ATI I run the risk of not only not being able to change the brightness but also not being able to go back to the integrated graphics (it once told me to close all 3d and video applications before switching when there was nothing open) Is anyone else having a similar problem to mine? I ran out of options at the lenovo site so I dont know what to do now. New drivers anytime soon? Best, Max

I have a laptop, HP4540s, which I use to capture video from a USB external capture card. It works fine, but I noticed that the laptop seemed to be using the Intel graphics all the time. On reading, it seems the default is not based on video processing, but that the laptop decides to use the ATI Graphics when 3D Video is being watched.  I dont' do 3D, but wanted to get the value of the high performance graphics, after all that is why I bought this laptop. So I set the Switchable Graphics to use the High Performance by adding the Capture application in to Catalyst Control Center and setting it to High Performance. I saw no change in preformance, and the Laptop CPU Occupancy remained just as high as when using the built in Intel Graphics. I had one occurance of a blue screen after a few hours running on the High Performance setting, and so have gone back to the default, and have lost my comfort in this so called High Performance setting. I don't know if it is even doing anything, and if so, if it is working correctly, due to the blue screen. (It was obviously rare, but I can't afford it to ever happen). I am happy to buy a new laptop, but even new ones are like this, so have a level of concern about this facility, and don't know what to do, to achieve the best performance with the best stability.  Laptop Specs: Probook HP 4540s Intel Core i7 3632QM at 2.2GHz 8GRam Windows 7 Pro 64bit SP1

Hi folks - any advice on this would be appreciated...

I bought a Satellite L855-14K about 2 weeks ago and I'm very disappointed to find that at times it is extremely slow. For example from entering my password at the welcome screen to seeing the Avast and ZoneAlarm icons appear in the system tray takes 5 min 45 secs.

Launching Chrome takes 1min 15 secs.

Launching Task Manager takes 40 secs.

I have done the following to see if I could find the problem...

Full system scan with Avast - no threat found.

Boot-time scan with Avast - no infected files.

Check C drive for errors - no errors found.

Optimise and defrag - completed.

Malwarebytes full scan - no malicious items.

Superantispyware complete scan - found 169 cookies, which I removed.

Looked at Toshiba PC Health Monitor and everything looked ok.

Ran the Toshiba Diagnostic Tool and everything passed.

I manually checked for Windows updates and found 5 optional updates were available, which I installed.

I have disabled a number of the items in the startup list - this is what's currently enabled...


I checked the Services tab of Task Manager and I have 78 running services.


Answer:New Satellite L855-14K is very slow

I spoke to Toshiba tech support who agreed that the machine was running slow and verified that the poor performance of my laptop wasn't due to any software I had loaded.

They then guided me through resetting the machine (after I had backed up all my important files), which meant I then had to reload all the applications I had loaded prior to the reset.

However, the reset appears to have worked as the performance is now what I expect.

My thanks to Henry and John at Toshiba tech support.

Motherboard and CPU present a temperature around 60? C while running idle, reaching 80-85?C while using the PC normally (browser/outlook/word).

Just some days before I faced this problem, the computer was running very slow and saw some warnings/errors in windows which I solved by searching on internet.

Dear Toshiba Community....

I purchased a Toshiba laptop like a half year ago for my study Mediadevelopment. I got the Toshiba Satellite edition L855.

When i received my order i was very happy with it and i knew that i would succeed programming on this nice device.

After 3 weeks of using it , i allready had a scratch just next to the camera. And i must admit that i really handled the laptop with care. I ordered a sleeve case and got it with me in a laptop bag. Even when the lid is closed there are small scratches around my laptop and this started me to worry about what would happen next.

While watching a episode of game of thrones. I noticed a red dot ... just in the middle of the screen. And i don't wanna be cocky but i must say that it aint cool when you allready have a pixel failure in using a laptop like about 1 month.

I received a update for a Driver of my DVD player tray. And toshiba TEMPRO told me there was a BLUERAY player in my notebook... but that was not true.. Just another point that dissapointed me.

Answer:Different issues on Satellite L855

Hi Jay

Generally speaking notebooks are not so sensitive devices so I don?t know how all this can happen, I mean with scratches and clicking noise. It is logic that notebook cannot always be as new one.
I handle my notebooks with care too but they are not in perfect condition anymore.
Cooling fan: try to reduce cooling fan activity changing cooling method option.
Control panel > power options > change power plan settings > advanced power plan options > Toshiba power saver > cooling method ? change it to battery optimized
This should reduce cooling fan activity.

> So i ask to you guys, Do you people know what i can do?
It is not easy to give you proper answer to this question. What you can try is to contact Toshiba service and ask for some tip. They should have experience with all this and they are in permanent contact with Toshiba so they should have enough info about all this.

By the way: several people have reported about this Tempro message. You should not be disappointed about that. This is automatic procedure and such mistakes can happen.

I have a Satellite L855-11k (PSKACE). The problem that I have with the laptop is the continued lag.

Explain examples:

Playing a game that does not ask many specifications, CS (counter strike 1.6) I can not play, because I'm playing +70 fps and suddenly when turning the camera or move through an area, the fps drops to 0, and blow less than 1s going back up to 70fps. No internet problem, the same thing happens offline.

Another example are the videos, like youtube for example, a 480p video to my laptop I would have to move smoothly, but devez then the image freezes (the audio keeps playing) and I can not see anything. After 1 to 2 seconds veulve itself. But this is very annoying. (Same thing happens to 320p, 720p or 1080p). With vlc nothing happens this, but as I see the video I can not do anything more.

Also I've noticed that with any program when you save a document, picture ..... , It costs more than laptops with less power.

Additional Information: I have windows 8 x64 (with windows 7x64 was the same), and I added a 4GB module more, so I have 8GB (1600MHz) ram. All the download drivers from the toshiba website []. I've also noticed that when I copy something to the hard drive THROUGH USB 3.0 port for a short period time 4-7s going at high speed 40MB / s, but then drops to 1-3Mb / s.

Answer:Freeze on Satellite L855-11K


The notebook supports the AMD Radeon? HD 7670M.
Therefore the hardware specifications are good enough to play games smoothly or to watch full HD videos.

In your case I recommend checking the BIOS version. Maybe there is an newer BIOS version which needs an update? furthermore try to update the ATI graphic card driver?

Additionally I recommend checking the HDD for possible malfunction.
The freeware tool called HDD drive fitness test could be helpful? This software allows you to test the HDD?

Otherwise i have no other explanation for the mentioned issue... it could and hardware or software related issue.

HP DV6 6121tx
Windows 7 64bit

I just reinstalled Windows and I want to update my graphics drivers to the latest ones (13.1). I'm runnning Dynamic mode.
So at first I installed the latest HP provided AMD Display drivers from HP's website
AMD High-Definition Graphics Driver HP Pavilion dv6-6121tx Entertainment Notebook PC | HP? Support

Now I thought I'm supposed to install any new versions of HP drivers *over* this since this HP one contained drivers essential for dynamic switching. But if I run the 13.1 installer and view the log, it skips over the display driver part and just updates AMD install manager and some other useless components.

How do I install 13.1 without messing up dynamic switchable graphics?

Answer:Updating graphics drivers on switchable graphics

Unless HP decides to release an updated driver, you're basically stuck with what you have. As you found out the driver from AMD won't install. That is because it doesn't include/support the switchable graphics.

Now with that said there is this modded set,


that includes both the latest AMD and Intel driver, and is modded to work with most laptops with that combination.

unfortunately i need to recover factory default with the recovery Media (3 DVDs which i created with the "Toshiba Recovery Media Creator" Tool before starting the recovery process).

So i boot the Toshiba Recovery Wizard from the Recovery DVDs and choose "Recovery of factory default software", which starts with copying the files from the Disks.

But it will come to a point when it asks me for a further Disk (DVD 4), which i of cause don't have. And when i checked the 3 REcory Disks i noticed that one was not complety written and one was even empty.
(DVD1: 4,4 GB, DVD2: 709,1 MB, DVD3: empty)

i can't repeat "Toshiba Recovery Media Creator" because the Hard disk is already complety erased.

this is why i aks for recovery media.
is it possible to download an iso image?


Answer:Where can i get Recovery Media for Satellite L855-150

Hmm? that?s strange?

In my case I received such message that Recovery disk are OK and the procedure could be finished properly.

I was hoping that someone would be able to help me fix my touchpad.

It keeps on freezing after I install the Synaptics drivers given on the official drivers page. It used to happen on windows 7 from time to time, but on Win8.1 it happens quite often.

It just happens on random. Left click, right click and scroll continue to work, but cursor won't move for a few seconds no matter what I do, and then it starts working again. It's really frustrating and it happens a lot of time, making the work on computer quite unpleasent. If an external mouse is connected, when it freezes I'm able to move the cursor using that mouse with no problem at all.

Has anyone maybe dealt with this kind of a problem before?

Thanks in advance & sorry if my English is bad

Answer:Satellite L855-14J - touchpad is freezing


out of interest, does the mouse freeze just after you have used the keyboard? my L855-188 (i know not the same model, but maybe the same driver/functionality) freezes the touchpad for a couple seconds after i have used the keyboard in any way to prevent misclicks apparently.

hopefully this page can help you, its how to turn off palm check on the synaptics software

I have a toshiba Satellite L855-10P and my webcam was working fine until today when, during a skype video conference, it started showing black lines a bit like static and the quality decreased significantly. I used the webcam application to check if it wasn't an internet issue and the same problem occurred.

I restarted the computer and removed the protective plastic from the webcam and nothing changed. It's a brand new laptop, it's only 2 months old. Is there anything I can do to find out the nature of this problem or should I just go ahead and use the warranty?

**Edit: I changed the quality to 1280*700 and the image had great quality but when I changed it to anything lower than that quality the static came back.

I'm using a Toshiba Satellite L855 laptop running Win 8,all was running fine until last night, after using it for about half hr I went to shutdown but instead it appeared to go into sleep as the two lights on the front were still on,one of which the power, was flashing after I closed the lid, which would suggest sleep mode.

Now here's the odd bit, no key or mouse use would bring it back to life, all I got was a blank screen with the cursor,so after trying all I could I had to remove the battery, I started the boot up and it worked but, on the Toshiba start up it said configuring your system,followed by the usual looking blue windows update screen,which said configuring windows features,after which it went into win8 with no problems!

I have a Sattellite L855-10P.
From time to time, the TEMPRO utility warns me that there is a new driver and gives me a link to download it.
However, when I launch the installer, it decompresses, telling me it will launch after wards, but then the window closes and nothing further happens.

If I go in the folder where the installer was decompressed and launch tinstall.exe, nothing happens. If I launch SMIPlayerSetup.exe, it tells me "Can not find our player in your system. Installation aborted.".

What's happening?

Answer:Can't install any drivers on Satellite L855-10P


Tempro is a tool which notify you about new uploaded drivers.
This isn?t a ?invitation? to update the driver. Its just an info that a new version is available.

Furthermore if download does not functions properly via Tempro, I recommend visit the Toshiba EU driver page and to download the driver from the page directly.

Answer:Satellite L855-14J works very slow

Hi babica

On this forum you can find many threads with the same theme. It is nothing new and ?logic?. Why?
New notebooks are preinstalled with recovery image. Recovery image is a kind of ?software package?. The most settings like Windows update are set to ?automatic? so after first start notebook make huge download and updates installation. All this runs in the background and you will not even know this.
This background activity slows down notebooks reaction rapidly.

What you must do now is operating system optimization. With other words you must configure your machine to save resources for important activities. How to do this?

-remove all stuff you don't need from the system
-check start-up option and disable automatic start for all useless applications
-set Windows update option from automatic to ?Check for updates but let me.....?

Please do this and I think you will notice that your notebook runs better.

PLEASE NOTE: before you do anything create recovery media (DVD or USB) using preinstalled Toshiba recovery media creator tool.

If you have more questions feel free to ask.

Good luck.

Hello everyone.

My battery (a 10.8V / 4200mAh) died quite a while ago and doesn't hold any charge.

Seeing as the L855-149 is a discontinued product it took a while to find a replacement battery (that the store I bought the laptop from would pay for).

The replacement is an 11.1V / 5700mAh battery.
Both are Li-ion.

Can I put the new battery in my laptop?
Or will it not get enough charging power and not be very good?

I am a recent owner of a brand new Toshiba Satellite L855-159 laptop.
I cannot seem to find any drivers listed for it. i have download some drivers from similar series laptops, like the ethernet driver. That works fine on it, but i cannot seem to find a working wireless driver anywhere.
I have tried the official toshiba page and the toshiba auto detect tool. It says it cannot find my product.
I have also tried entering the serial no. manually and it gives me the same answer.... your product cannot be found or invalid serial no.
(i have tried all versios of toshiba site, in many different languages)

Only time my serial number worked is when i registered the laptop for warranty.
So, i must say that it has been a pain to find the right drivers for my product, and it would not hurt to have a cd/dvd with drivers in the box with the laptop. i know it should be a better solution to have drivers online because you always get the newest version, but a dvd with drivers that always work for your laptop is necessary when the main site FAILS so badly at providing them.

Hi there, I too have concerns about my Toshiba L855 and the overall heat being produced.

I bought a high spec laptop as I do use it for intensive multiple browser sessions and software.

This evening I reached 5gb used of 8gb, average CPU 15%, disk writes 25%

Temperature got to about 74c.

I have had the laptop cut out 3 times in the last week or so due to overheating.

At the moment the Toshiba health monitor is saying Im at 68% CPU temp and 68% fan speed.

The heat being generated is crazy, why not just give us an option to have the fan run at 100% and take some more heat out.

Laptop is only 6 months old and under warranty. My behaviour and usage now is no different to when I first bought it.

Any advice ?

Answer:Satellite L855 cut out 3 times due to overheating

>The heat being generated is crazy, why not just give us an option to have the fan run at 100% and take some more heat out.

I guess you don?t know that you can control the CPU and the cooling module performance.

This can be done in power management settings:
[How to handle the power management features of Windows 7|]

You should focus on the Cooling Method and Processor power management option

Furthermore the notebook?s temperature depends on notebook usage.
Performance heavy applications stress the CPU and GPU and this leads to more heat dissipation and higher temperature.

Last but not least ensure that your notebook is placed on the table and ensure there is enough free space to keep the fresh air circulating.
Don?t use the notebook in bed, couch or knees.

Bios update for L855
The only detail I can find is:
*This Bios Update adds increased functionality to your system.*

A more detailed explanation of this 'functionality' would be useful in deciding whether to update the bios, or should one update as matter of course and assume it wouldn't be offered if not useful?
Reading other posts suggest it's something to do with Bluetooth, which although installed, I have never used.

Answer:Satellite L855 - Why can't updates be more specific?

You are right but as far as I know only on Toshiba US page you can find detailed BIOS update with all necessary information.
Anyway if there is no problem with your notebook BIOS update is not necessary. In worst case fan activity can be changed and you can be faced with more cooling fan activity that can be very annoying.

Some people have reported about such issues in the past. So if there is no reason and you are happy with your notebook don?t change anything.

Hi all,

I've had this laptop nearly 4 years, or is it 5? This morning, I woke up to find it was no longer charging the battery and the computer doesn't recognize an AC adapter plugged into it.

The computer itself works fine. I am not able to update BIOS because it wants me to plug in to AC power to do so, so I had to use nearly all of my remaining battery power to back up the data onto a portable external drive.

Changing outlets did not help. It's the same AC adapter that came with the computer and worked fine all this time.

The battery is now about 7% and I turned it off to save what little juice is left.

Not sure how to address this issue from here onward.

I can use 2.0 devices in the 3.0 ports fine, but my 3.0 device will not work. It connects then disconnects once, not showing up in device manager at all.

I've tried installing the USB driver off this site for my model. That made no difference.

Any ideas? Thanks.

Hi everybody,

I recently got a Toshiba Satellite L855-15U and I'm hearing an ongoing soft grinding sound from the HDD in the laptop.

There is an occasional click and bit of a soft rattle type sound too. It sounds like the usual mechanical sounds of a HDD, but a sound one would have expected only to be heard on computers 10 years ago.

There appears to be no noise reduction or elimination of sound. Is this standard with Toshiba and Hitachi?
My old notebooks were almost dead silent so that is why I am concerned.

The problem is an irritation more than a problem with functionality. The computer is not registering any errors so therefore there is no obvious fault with the laptop as far as diagnostics is concerned.

I would love some advice or suggestions on what all this means before I make any decision to go back to the store with it.

Thank you.

> There is an occasional click and bit of a soft rattle type sound too. It sounds like the usual mechanical sounds of a HDD, but a sound one would have expected only to be heard on computers 10 years ago

I know this HDD sound.
I had some external 2.5? HDDs in the past and some of them created exactly the same noise.

All the HDDs worked properly but sometimes such noise was noticeable especially while reading or writing the data.

I assume such noise is created by HDD head.
From my experience its not a HDD malfunction but sometimes it?s simply annoying.

Hello everyone,
Does someone know when toshiba will release a new driver for the AMD graphic cards ? Because the one that s on download is ONE YEAR OLD ! It s from 12/12....I ve tried going on the AMD site but they say that the driver they provide doesn t support toshiba laptops...I m pretty sad about having a one year old driver for my graphic card.

Answer:Re: Satellite L855 and AMD display driver update

You must not be sad about that. There is big difference for laptops and desktops support.

As you know for desktop GPUs manufacturers offer new versions almost every month.
With notebooks situation is a bit different.

Due to specific design and construction GPU performance must be ?under control?. More performance means more heat and more heat can be problematic for notebooks hardware. Cooling system is designed to offer optimal hardware temperature. It is a bit complicated.

All you can do is to check for newer versions offered for newer notebook models.

By the way: which GPU is inside?
I would like to check if some newer model with the same GPU has preinstalled newer driver version.

After having had a Toshiba laptop previously I bought a new Satellite L855 on Saturday. Sad to say I am REALLY disappointed with the speakers and sound quality. Especally as stickers on machine say 'Large speakers for deeper sound' . It sounds really tinny. Much worse than my ipad or iphone :-(

Any sggestions?

Answer:Poor sound quality on Satellite L855


Your notebook supports an Realtek sound chip. Right?
In control panel you can find the Realtek HD Audio Manager.

Here you can change the sound effects? you can change the sound properties and can add some deep bass using the equalizer settings.

I got Toshiba Satellite L855-B412 which I bought last year which came with windows 8.
I upgraded to windows 8.1 through windows store and then updated the system derivers for windows 8.1
then I backup the system on 2 DVD's using system backup utility from Toshiba.

When I restore system from those DVD's will I get windows 8.1 or the old windows 8?

Answer:Satellite L855-B412 - Making recovery DVD's for Win 8.1

Toshiba recovery media creator doesn't create recovery image from actual operating system but just copy original recovery image designed by Toshiba.
With other words after usage of recovery discs you will have identical Win8 version as you got it with your new notebook.

I'm running a L855 laptop and over the last day or so I've noticed in event viewer every min or so I'm getting a ATI client event error, no more details are available but it's entering a new event for it about 1 min!

Everything seems to be running fine though, anyone know what this is and how to stop it?

Answer:Satellite L855 - ATI client event error

> Everything seems to be running fine though, anyone know what this is and how to stop it?
ATi client must be related to the ATI catalyst control center.
The ATI Catalyst Control Center software application gives you complete control of performance and visual quality of your ATI Radeon graphics for a personalized visual experience on your notebook.

You could try to reinstall the ATI driver but to be honest I don?t know if it would help you to stop viewing the errors in event viewer.

At the other hand, if your notebook is running properly I would not be worried about ?some? entries in event viewer?. This isn?t really important

Also the Symbols shown on my desktop are don't match with the keys on the keyboard anymore.

I have Satellite L855-188. I have a question. My note is at home, almost every time. So How should i charge it? Can i use it, when always connected to electricity? Or i must sometimes disconnect it?

Answer:Satellite L855 - question about battery charging

Generally speaking you can do whatever you want. For instance my notebook is permanently connected to AC adapter and I use it every day. What you can do is to use it from time to time with battery power supply. Just make the battery empty and connect it to AC power supply again. Do it once a week.

Generally speaking you must not do it but you can do it from time to time.

I tried to make a recovery from an usb stick. I have done the recoverymedia with the "recovery media creaotor" by toshiba and it was sucessfully done.
After i started the recovery it aborted at maybee 80% (i cant say it bacause i wasnt in the room, i think i had to choose 2 or 3 times the yes button that I inserted the next disc even if I used an USB stick ).
Now i cant even start the laptop i just can choose between 3 options(loading recovery data & starting bios) and the laptop isnt recognizing the usbstick anymore (the recovery data is still on the stick)

Answer:Satellite L855-150 recovery aborted now i cant start it

Enter BIOS settings, set it to default settings and restart your notebook with USB placed in USB port. Press F12 at start-up and check if USB is listed as bootable device. If yes try to start recovery image installation again.

When i'm in "youtube" or "in windows media player" or expecially when i'm playing LoL (League of Legends, online game) my computer crashes for a few seconds (one or two) and when it crashes it makes a noise too.

If i'm with headphones i listen that noise in headphones. I already tried everything like reinstalling video card and sound drivers, and it didn't change anything, the crashes and noises remain. I don't know what else should i do..-

Is there any solution? I cant even find what is the problem.. And the store's tecnic seems not to be able to solve it either..

I appreciate your help.

Hello everyone,

I have a problem with my Toshiba Satellite L855-124 PSKACE laptop.
After upgrading to Windows 8, I can't change the brightness backlight of the laptop screen.

There seems to be an error in the graphical driver.
When I install the Windows 7 graphical AMD driver under compatibility, it works again but bugs out on other areas.

Anyone have any ideas?
Even after using the upgrade assistant provided by Toshiba it does nothing.
Also the drivers for my laptop are poorly updated. Dating back to 2012.

I have also called tech support, they told me that a driver team will be fixing the issue.
That was 2 months ago.

Is there anyone from Toshiba that can help me with this please?

Thank you.

Answer:Satellite L855-124 can't change display brightness after Win 8 upgrade

>When I install the Windows 7 graphical AMD driver under compatibility, it works again but bugs out on other areas.

Answer:Satellite L855-14J - How can I enable intel quick sync?

You will need to install the Intel HD Graphics 4000 driver using another method.
The installation should work installing the driver within the device manager.
Here you will need to choose the “Advanced” installation procedure which helps you to point to the driver folder which you downloaded from Intel page.

Note: you should download the driver ZIP package (not exe)!!

My Satellite L855-14K is mostly used when plugged in. The screen changes every few seconds from bright to dim - at the same time the logo in the taskbar switches from [plugged in, charging] to [xx% remaining] and the mains plug disappears from the logo. I have changed the power setting to [high power] and changed the setting to never dim or switch off the screen, and the screen brightness has been set to maximum. There is still a visible difference and it drives me nuts.

The machine runs Windows 7 Ultimate and has a 750GB SSD, 16GB of RAM, and software and BIOS are up to date. Battery and power supply have been exchanged with known good ones and the power supply is uninterrupted.

Does anyone have any ideas?


Answer:Satellite L855-14K - randomly switching between power settings

According notebook specification your machine was delivered with Win8 64 bit. Have you noticed the same behaviour with original preinstalled OS?
Since when have you noticed this strange “switching” between power and battery power supply?

To be honest it is not easy to say for sure what is wrong there but I think it cannot be software related issue. I can just imagine that software gets some kind of “signal” from power supply electronic.

Is the warranty still valid?

Hello everyone,

My question is about the Recovery Media Creator procces.
I was about to create the recovery and I noticed there are several options (DVD 4.7 Go, DVD 8.5 GB and USB Flash).

My Toshiba Satellite L855-12X is with a Blu-ray Disc Drive burner and would like to use a BD-RE I bought for backups.

Does anyone have a solution to use this media ?

Answer:Satellite L855-12X: How to use BD-RE with TOSHIBA Recovery Media Creator

I have the same optical disc drive in my Satellite but no option to use empty BD for recovery media creation. I presume preinstalled Toshiba software cannot handle with it.
Best thing you can do is to create USB recovery media.

To be honest I?ve created two back-ups (DVDs and USB). I can always use one of them if necessary.

the new driver and installed the old driver again from this site. Now the brightness adjustment works fine again but I don?t really want to get stuck on this old driver version. Its about 8 months old. Before I bought my notebook I never heard anything about their update policity. Can someone tell me when they plan to update their toshiba-own-amd-drivers? I really want some new drivers but I don?t want to loose the ability to adjust the brightness. For me its a reason to give the notebook back, but I really like this notebook except of its own drivers.

Can anyone tell me, how long it will take to get some new drivers? And I mean NEW drivers not newer than the old ones but still 6 months old.

I found another thread about the same theme.
It seems that brightness control FN buttons don?t work using NON-Toshiba graphic card driver.

You should know that graphic card driver from Toshiba page is an modified driver, created and configured especially for Toshiba notebook models.
Such driver supports an overheating protection. Other drivers don?t?

However, it looks like there is no other solution as to use the Toshiba configured and modified drivers.

I hare recently upgradedmy Toshiba Satellite L855-149 to the most recent windows 8 version 6.2 and since I have done so the Synaptics touch pad has stopped working, I presume because the driver does not work with this version of windows 8. What can i do to resolve this problem so that i can use my computer without a plug in mouse again?


Answer:Satellite L855-149 - Synaptics touchpad not working after Win 8 upgrade

Hi Simon !!
I have just clean installed windows pro 8 on my satellite r830 and i had the same problem (actually, the touchpad still worked but not the scrollbars).
What you need to do is download the driver via this website, unzip it and execute it. It will work just fine. Locate it under 'windows 7 64 Bit' (or 32 Bit, depending on your OS) and not 'Windows 8 - Upgrade' as synaptics still hasn't realized a specific driver to windows 8.
Use the assistant on the website to find the proper driver faster (the reference of the model is written on the back of the laptop)
So far, it's the only driver that i have installed. However, the button near the touchpad that activates or deactivates it still doesn't work. Maybe it will work again when i install the other drivers.
I hope this can help you ;)
