Satellite L755-128 - CPU compatibility issue

Question: Satellite L755-128 - CPU compatibility issue

Hello dear colleagues,

As the title says, I have a Toshiba Satellite L755-128 code PSK30E. It has a 2nd generation Intel i5-2410M processor.

Laptop running fine and all, but I recently got a nice deal on a newer laptop, with overall lower specs, but a better processor. It is a DeII Latitude E5530, with a 3rd gen Intel i5-3230M.

Going on Intel's site, I saw that basically both processors have the same TDP of 35W, and same package size, both run on HT and have dual cores, the only difference being that the architecture changed from 32nm to 22nm and the frequency is higher.

Also, 2nd gen supports 1066/1333 MHz memory, and 3rd gen supports 1333/1600 MHz. My memory is 1333.

Of course, as you guessed, I intended to swap the processors between the two laptops. Upgraded the BIOS on both of them, then replaced processors, re-assembled, and at start-up, surprise: The DeII recognized the older version of i5, ran fine and all, but the Toshiba didn't.

It just opened when I pressed the ON button, but the screen remained black. Then I pressed again the button, it shut down as normally. (I repeat, BIOS already upgraded, as somebody recommended). I disassembled again the Satellite, checked if everything is in place, and second start-up time still the same.

Then I got annoyed and swapped back the processors onto their original Laptops. And, both of them are running just fine.

So if somebody came across this problem could you please advise if you managed to sort it out?
What seems to be the problem, does the Satellite motherboard does'n not support the 3rd gen Intel?

If so, why? Or if it could work, what should I do?

Thank you in advance!

Answer: Satellite L755-128 - CPU compatibility issue


I don?t know any notebook manufacturer who would officially support an CPU upgrade.
Mostly the CPU upgrades on notebooks are your own decision and nobody could provide you an confirmation that an notebook with new CPU would work or run properly.

Indeed many people try to update the CPUs and in many cases this works? also on Toshiba notebooks.

But there are some important notes:

1) you have to ensure that the chipset on the motherboard would support new CPU. In case it doesn?t, you cannot use it

2) even if new CPU would be supported by chipset, there is still open question about the BIOS support. BIOS is modified for each notebook series and it could be possible that some CPUs would not be fully compatible or supported by BIOS.

As you see, the CPU upgrade is not very easy and it?s no matter that another notebook which was equipped with the same CPU as the L755 supports the other CPU? there are much more factors which could affect such upgrade.

I have problem with my keyboard since I bought the notebook, first some keys are not working or give different letter, I send it for repair and they replace with new one.

Now I have same problem again but sometimes.
I need to restart to become normal. Any one can help.


Answer:Re: Keyboard issue on new Satellite L755-16H

I don?t know what do you mean with restart but what you should do is to contact service again and explain the situation.

Ask if BIOS update can help. if yes I recommend you to update BIOS to newer version.

Check please Toshiba download page and compare last offered version with preinstalled one.

Are they identical?

My L755 is fairly new and was working fine. However, the battery is causing me concern. Today I turned on and the battery icon showed about 80%. I used the laptop, on battery, for around 10 minutes and the screen went blank and would not come back on.

I plugged in the mains and pressed the power button - it told me that is was recovering from a low power shutdown. I watched it charge, and it got to 80% in 15 minutes and sat there for 30 minutes before jumping to 100%. I unplugged the mains, and it went straight down to 80%. I suspect that the battery monitor software is to blame, but is there anything that I can do recalibrate it.

Then again, could it be a bad battery?

Answer:Battery Charging issue on Satellite L755-1LN


For me it sounds like battery issue? but try to calibrate the battery.
Remove/disconnect the AC adaptor and leave the notebook disconnected until the battery would be fully empty. Then connect the AC adaptor and leave it connected until the battery indictor would switch to green (or blue).

This procedure should be repeated two, three times to recalibrate the battery but if the battery is faulty this workaround would not help a lot.

I have two problems with my laptop it's satellite L755-M1KQ ,

my first question is, can i download windows 10 on it?

my part Number is PSK2YE-0KQ02UAR

my second problem is the sound in my same laptop doesn't work , not always just sometime , please help me .

Answer:Satellite L755: Win 10 upgrade question and sound issue

Of course you could upgrade the system to Windows 10.

The hardware is strong enough to handle the Windows 10.
But Toshiba does not provide Windows 10 drivers for this series… therefore it could be possible that some notebook features (FN buttons, etc..) would not work properly….

Regarding the sound:
You did not provide many details and if the issue cannot be replicated, then it will be very difficult to find a fix…
I think you should check whether the sound issue appears using headphones or speakers only… also check if you could update the sound driver…

Bios upgrade for L755-128 (PSK30E) was never released. Current BIOS is 1.90.
Is it safe to upgrade to 2.70 from L755-12D (PSK2YE)? Very same laptop except added blue-ray drive.

Answer:Satellite L755-128 (PSK30E): Can I use BIOS for L755 PSK2YE?

Do not use BIOS for other notebook model.

If the newer BIOS is not released that means probably that there was no reason for that.

Hi there

Recently got a Toshiba L755 and have been having an issue with audio & video playback since I got it.
I have updated the latest drivers for the Conexant HD Audio card and this made no difference.

Basically during playback there is an intermitant distorted sound during mp3 playback, video playback and online streams.

I have tried different programs and the same thing happens, however, when I have a LAN cable plugged in there is no issue - it is only when im connected to the net via wireless.
I have a netgear router which is working fine.

Can anyone please tell me what might cause the wireless to create this issue and how to go about fixing it?

many thanks

Hi There

Apologies if this question is in the wrong part of the forum but I need help with a battery problem for my Toshiba Laptop.

I have a Satellite A300 and have done for about 4 years.
The battery recently has not been holding charge and I put this down to age so ordered a new one online.
My previous battery had Model Number PA3534U-1BRS with DC 10.8v and 4000 mAh and my new battery is also PA3534U-1BRS with DC 10.8v and 4000 mAh.

The problem is that the computer doesn't seem to like it.
If I put the battery in and connect the power adaptor the red battery icon will show and remain for around 5 minutes before starting to flash.
When I turn the computer on and log in the computer displays 'battery not detected' in the battery icon on the toolbar.
I have not been able thus far to charge the battery.

What am I doing wrong ? Any ideas on how I can get around this ?

Any help gratefully received


Answer:Satellite A300 - new battery compatibility issue


First of all there are no many things which need to be done if you replace the battery.
The new battery should be recognized automatically by Windows system and notebook.
If it?s not the case then the battery is not fully compatible or it malfunctions.

There are many batteries on the market; original parts and not original parts?
I recommend buying an original Toshiba batter from Toshiba service in your country.
In such case you can be 100% sure that you have bought an right and good part for your notebook.

Has anyone ever tried installing a SanDisk SSD to a Toshiba Satellite laptop or know if these two in general are compatible or not?

I am specificially looking into insalling a 240 GB SanDisk Ultra II SSD on my Toshiba A200-1BP, or PSAECE-01U00XTE, to replace the existing 160 GB Toshiba 2.5" SATA HDD (MK1637GSX).

The SSD seems to have the right form (2.5") and the interface (SATA) but I am not sure if these two are enough to ensure compatibility. Unfortunately, SanDisk says (unlike Crucial for example) it does not provide compatibility information for specific computer models. Thank you.

Why can I not install Windows 8 Consumer Preview on my Toshiba Satellite L750-22x?
I get a processor compatibility error.

Intel i3 M380 2.53GHz

Answer:Cannot install Windows 8 on Satellite L750 - CPU compatibility issue


The internet provides some details about this error message.
It seem that in order to install the Win 8 CP the CPU should support PAE/NX/SSE2 features

Never-eXecute Bit ( [NX bit|] ) allows marking of memory pages as non-executable.
Streaming SIMD Extensions 2 (SSE2) is a previous standard that is supported by Intel and AMD CPU. Therefore all CPUs that support NX would also support SSE2 too.

Usually enabling the XD (for Intel CPUs) or NX (for AMD CPUs) in BIOS should disable this error message.
But if this is not available in BIOS then either the CPU does not supports this feature or the BIOS does not support this option.

According to Intel Ark page the Intel Core i3-380M supports Execute Disable Bit. So possibly the BIOS does not support this feature

It seems you need to wait for new BIOS

Each notebook model (L750-xxx or L755-xxx) is equipped with different hardware parts.
In many case the hardware specifications are very similar but there are still small differences like different CPU, LAN or WLan card?

A 1-day-old Satellite L755-144 has a constant whirring sound and vibration across the front half of the laptop body. I thought this could be the fan, but it happens even when the Toshiba PC Health Monitor states that the fan is at 0%, and when the computer is idle (no windows open).

How much noise should this machine make when idle (I'm finding it distracting)?

Answer:Satellite L755-144 - HDD noise?

Hi buddy,

Are you sure that the noise is coming from HDD? You can test this if you remove the HDD and start your notebook without one.

Generally speaking the HDD always creates a little bit noise because the platters of HDD spins up and this is causing noise. Also the head is doing this is data will be read or write.

So a little bit noise is normal but nobody can tell you if everything is ok with your notebook or not. It?s just an user to user forum where you can talk with normal people like you and me. If you are not sure and want an official answer contact an authorized service provider and ask for help.

By the way: On my Toshiba notebook I can only hear the HDD if I put my ears on the case.

I have a 2 year old Satellite L755-1LM. The instruction manual says that it might have a USB 3.0 port as that was optional on some models.

Is there an easy way to find out if my model has this? I have been told that USB 3.0 ports have a blue insert rather than black, but I do not know if that is true in all cases (mine is black). I have attached a USB 3.0 standard HDD to the left USB port, which is the one that might be 3.0, but the transfer rate is poor. Therefore, it is either 2.0 only or I am missing drivers etc.

Thanks for your time and effort should you help

Answer:Satellite L755-14Z - CPU upgrade possible?

Generally it is difficult to upgrade the CPU in notebooks since the notebook is designed for specific CPU's. If a CPU is installed that is not supported, it may draw too much power and cause instability, or it may overheat the notebook.

You can probably use a CPU from another L755 model, but it probably wont make much difference.

I have Toshiba Satellite L755-11W, its i5, can I change it to i7?
Thx for help

Answer:CPU upgrade on Satellite L755-11W


I think this would be possible since the chip handles the i7 too.
But as far as I know no one of the notebook manufacturers supports such upgrade officially?
What does this mean now??

This means that you do that you own risk and in some cases the BIOS would not be compatible. So in worst case the new CPU would not work even if the chipset would handle this?

By the way: such upgrade cancels the warranty.

Firstly, I'd like to say I'm quite useless with computers.

I used the Product Recovery CD, followed all the steps, it took like 30minutes. And then it was done. After it finished there were a number of problems that have appeared:

Windows isn't genuine?
Network adapter won't find any internets? Need to install a driver?
Screen resolution doesn't give the option for the correct one.
It's a stranger version of windows 7, the bits where windows is concernig are all coloured and aren't translucent. - But I'm not sure if this has to do with 32-bit and 64-bit whatever they are.
^ I have figured that I now have 32bit downloaded onto that computer, when it is actually a 64bit.

I posted on the US forums and have realised that I've used the wrong CD, the CD I used was a recovery for an L500-19X.

Not sure if I'm using the correct disk, as I own 2 toshiba laptops.
On the disk it says GMR410014EN0
Windows 7 Home Premium 32bit
Support for these products provided by Toshiba Europe GmbH

Answer:Recovery for Satellite L755-17Q

> Just a little more information.. I'm not sure if I created this 'recovery medium'
What to say after reading this?
So let?s be clear now: according notebook specification your Satellite L755-17Q was delivered with preinstalled WIN7 64BIT HOME PREMIUM and without recovery disc. Recovery disc must be created by notebook owner. If you don?t have it and you want to install original recovery image for L755-17Q you must order it on

If you have European notebook model why do you discuss about it on US forum? European models don?t have anything to do with US models, US market or US support.

There are many options to install drivers: search & install individual driver (this is my choice) or download driver pack (e.g. from - it is simplest way.

Generally all you have to do - google vendor & product ID of unknown device (see

Recommended order of installation:
1. Chipset software (I hope Intel is your choice?) then reboot.
2. Network controllers.
3. SP3 and updates (if it is not installed earlier).
4. Other devices - video, audio, touchpad etc.

It's hard to find drivers for AMD or Nvidia video controllers - usually drivers are branded by supplier (Acer/Toshiba/etc) and are not on amd/nvidia sites. In such case you have to do a little of magic to modify drivers.

At the moment your notebook should have one single 4GB RAM module inside and it is DDR3 1333MHz (PC3-10600), 204p with part number PA3918U-1M4G.

In my opinion you should obtain second 4GB RAM but with the same specification and part number.
With two identical RAM modules there is no risk of some compatibility issues.

Don?t mix two RAM modules with different specifications.

Check if you can find somewhere RAM with part number PA3918U-1M4G.
I don?t have this notebook model but I presume at the bottom side there is placed memory cover.

There's constant vibration around my mousepad and it's getting annoying, my laptop is only a couple of months old. Maybe you know what could be causing it and how to solve it?

I have BIOS 3.60 and I can't downgrade it because my model isn't on support your model page.

Answer:Vibration on my Satellite L755-1LE

Vibration is definitely mechanical malfunction so it can be fixed by authorized personal only.

My advice for you is to contact nearest authorized Toshiba service provider and ask for help. They can open the case and check all hardware components.

Hi Sirs;

After I update my laptop Toshiba Satellite L755 to Windows 8.1 and when I press FN+F8 to off or on the Wi-Fi or Bluetooth it is not working.

I removed VAP then system driver and then functions key utility and re installing it not Success to turn of,

please any advice?

Answer:Satellite L755 - after Win 8.1 upgrade cannot use FN+F8

Windows 8.1 does NOT support the Value Added Package anymore!
The VAP was released for Windows Vista, Windows 7 and Windows 8 Upgrade

Notebooks which were preinstalled with Win 8 do not contain VAP anymore!

But the Satellite L755 does not seem to be Win 8.1 supported.
So you will be lucky man if you will get these function buttons working.

I can recommend you to check the Win 8.1 driver released for Satellite L855 series.
Install the Toshiba Function Key Utility and Toshiba System Driver
Maybe it would help?

I own a Toshiba Satellite L755-16C Laptop. The DVDs I have run on it before (installing games, softwares, movies, etc) are no longer detected by the DVD Drive. CDs do work for some reason.

Whenever I insert a DVD Disk in the drive, the light blinks and I feel some movement and hear some noises that typically happens when a Disc is entered and being read. However the contents of the DVD Drive do not show. If I click open the DVD Drive from My Computer, the DVD ejects and the computer asks me to enter a Disc, as if there was no Disc inserted.

I downloaded the latest BIOS files from their website but nothing changed.

On this virtual way it is not easy to say what is wrong there. At first try to clean the lens up. Maybe is lens dirty.
Other way it can be mechanical problem. Fact is that lens position is different for reading CDs and DVDs. Maybe is there some problem with lens calibration.

I can't understand how as this is supposed to be better,
Is there any known problems please.

Answer:Re: Satellite L755-1NP runs very slow


I think many preinstalled tools and utilities would be executed and started while notebook boots the Windows system? you should know that these processes which run in the OS background can affect and slow down the system.

One solution: try to disable some processes which are not really necessary.
You can do this running msconfig.
In search line type msconfing and start this too. Now go to StartUp tab.

Here you will see a lot of processes which would be executed.
You can remove the mark from the line in order to disable the single process.
If you don?t know what a single process controls, google in the net to get more details.

What antivirus software are u sing?
I use the freeware software called Avira Antivir. It?s a smart application which does not need a lot of hardware resources. I had a Norton Antivirus and this software slowed down my system extremely?

Last but not least use the CCLeaner (also a freeware software) to clean the registry and to remove some garbage from the system.

Good luck

> I?ve read that should work around 3,5 - 4 hours. 2 hours seems poor for me. Is the third complete charging, from 100% to 3%.

Battery working time demands on the notebook usage. So if you run high performance games or other software and use a lot of hardware performance then the battery would discharge much faster!

If you want to extend the battery working time, then you should check and change the settings in windows power management

Hi All,

I've just bought this laptop Satellite L755-15R, and all the spec and stickers and paperwork says that it has Bluetooth 3.0 + hs.

It has all the Toshiba bluetooth stack software, but it would not install properly or fire up. In fact it conflicted with the WLan card and turned it off. Marvellous....

Having looked through the forums, I can't see if anyone one else has had this issue on this particular model.
It would be nice if Toshiba actually listed which of their laptops actually has bluetooth enabled (I can't find a web page that tells me anywhere)

Can anyone one advise....a Toshiba laptop PC expert would be nice...:)

Methinks the paperwork is misleading and mis-represents what these laptops actually have on them.

Your help is much appreciated... guys and girls

Hi all. I purchased a new laptop today.. it would not charge the battery so I exchanged it in store. The replacement also has this problem. Am I doing something wrong or have I just been unlucky?

The battery icon at the lower right of the screen tells me that the battery is 0% charged, but is charging.The red light on the laptop near front left is lit as if to show that the battery is charging also.

Yet the battery is not charging.

If I were to unplug the laptop from the mains, the laptop switches off instanty.

This is the second brand new laptop with the same problem today. Perhaps part of a defective battery batch or is it a problem that can be corrected with software? I don't want to have to take the laptop back to the store for a second time in day.

Answer:Satellite L755 would not charge the battery


If the notebook shuts down immediately after the AC adaptor has been disconnected, then this means that the battery is empty and not charged.
Are you sure that you plugged the battery properly into the battery bay?
Please check this if the battery fits correctly.

Additionally I recommend removing the battery and disconnecting the AC adaptor.
Then press power button 30sec long and plug both parts again.
Then leave the notebook connected to mains for a longer period of time (2-3 hours).
Then check the battery charging level?

If it would still stay at 0% then I would recommend visiting you dealer and to check other unit or battery.

Answer:Satellite L755-128 shut down for no reason

In my opinion there are too many issues with your laptop and you should contact nearest authorized Toshiba service provider and ask for help. I?m pretty sure your notebook still has valid warranty so why to spend your time on forums and search solution for such issues that probably cannot be solved without hardware check. It must be hardware related issues so there is nothing you can do about that.

Contact service, explain the situation and they will help you with this.

Answer:Satellite L755-10Q automatically shuts down


In most cases the notebook shuts down automatically because of the high temperature.

Usually the cooling modules should be able to cool down the notebook properly but if the cooling modules don?t work properly, then the CPU temperature could goes up to a critical level and this would lead to shut down?
In most cases the dust and debris inside the cooling modules prevent the fans from running with best performance? so in such case the dust needs to be removed? I use compressed air spray that helps?

Not sure if dust could be the reason for your problems but I think that the high temperature could be possible? the temp in Saudi Arabia is high and you should ensure that there is enough free space around the notebook to ensure good air circulation?

You could also try some additional cooling pads which would cool down the internal parts?

HI, my Toshiba Satellite L755 is 2.5 years old running windows 7 home 64bit. The OEM battery had been losing capacity over the past 3 months. One fine day, the laptop shut down.

On turning it on again, i got the Replace battery sign in the bottom left corner with remaining battery capacity being shown at around 45% . Over the next few weeks this started occurring more often. From restarting once a day in the beginning, it went to restarting every few hours. The battery capacity dropped from 45 to about to 20% so i decided to remove the battery and work on AC.

This worked fine for a couple of days , but then one evening the dreaded restarting started. At first it was only once a day. Now a week later, my system restarts every 3 or 4 hours. On restarting , the display shows that windows shut down unexpectedly, and if i would like to start windows in safe mode or normally. When i select normally, sometimes the laptop runs checkdisk.

Due to this annoying problem, i also ended up damaging my 500gb Toshiba canvio EHDD as i was formatting it when the laptop restarted unexpectedly.

Please help

Answer:Satellite L755 restarts without warning

For me it is not easy to say if these restarts are related to power supply electronic and I cannot say for sure why this happen. Generally speaking you should be able to use your notebook without any problems using AC adapter only. I have the same situation with my old Satellite A300 and there is no problem at all.

This suddenly shutoff is a bit suspect to me and maybe is this some hardware related issue. I see two possible reasons for this: either is power supply completely cut-off or notebook switches off due to some other reason that can be overheating.

When you take a look on LED panel when this happen, can you notice that there is no DC in LED ?

My laptop is Toshiba L755-16H, windows 8.1 update

All what I get now is the first screen of ?Toshiba Leaading Innovation? and ?H2O bios? then the logo of windows 8 (4 blue quartered window) then black screen with flashing cursor and the mouse arrow, and it keeps like that.

The details as follows:

it was working normally until certain critical update is installed from Windows update, then it refuses to load windows at all and gives error message.

1- in the beginning i tried to get into recovery options> advanced options> repair start up> but no benefit.
2- then i tried system restore> it failed and no benefit.

Answer:My Satellite L755 - Win 8.1 cannot load (boot)

Thanks sincerely for every one tried to help me.

Nearly the problem has been _RESOLVED_
I think it was a matter of corrupted Master File Table (MFT) and volume bitmap and also Malware detected.

Here you are the details:
I removed the HDD from the defected laptop, and connected it to a SATA enclosure and connected it via USB cable to another working laptop.

I have performed a scan with antivirus (360 Internet security) but I didn?t leave it to finish. It has detected a Trojan in the following path ? \Program files (x86)\Toshiba\Bluetooth Toshiba Stack\LANG\PTB\BTAssist.chm? detected as Advanced Level Trojan Program.

I believed it may a problem of corrupted Registry or File system, so I have performed Error checking for the Windows partition (from Properties of the desired partition the Tools tab then ?Check? under Error checking section, it found some errors and fixed them . then I stopped the antivirus scanning, connected the HDD and tried booting but no improvement.

I believe that that way of error checking is not very effective and the better method is via the command prompt so I opened cmd , then entered ( chkdsk driveletter: / r ) then it found many errors in the MFT and volume Bitmap (I am attaching a file containing the result). It corrected the errors.

I removed the HDD and connected it, and WOW the option to enter BIOS via F2 and boot sequence via F12 returned as a bottom line, and I could enter BIOS setup.

Hi everyone,
I just received from Tempro the advice that there is a new driver for my dvd unit,
this is the link to download it.

Point is the description says 'it provides you the capability to play back Blu-ray discs' and this would be great but I've got a Satellite L755-1DW mounting only a dvd unit and not bluray one so I don't think this is possible, isn't it?

I've tried installing it but after extracting the software autokills itself without even displaying an error message.


best regards,

Hi every one ..

i just bought this laptop ( Toshiba Satellite L755 ) and i had to recover it by the 4 recovery discs .. but i found out the first recovery disc is damaged and i don't know just why .. i read the manual and i made the 4 recovery discs successfully without any problems .. so please tell me what will i gonna do about it ??

The other 3 disks is working well i need only the first disk data where or how can i get them ????

Answer:Re: Satellite L755 - the first recovery disc is damaged

Sorry but your question is really strange.
All we know is that you want to install recovery image and that first disc is not working.

What kind of solution do you expect now?

Can you start preinstalled OS?
Is preinstalled OS original Toshiba one?
Can you maybe create these discs again?

I really don?t know what to say about it. If you cannot create new discs, created doesn?t work but you want to have original Toshiba recovery image preinstalled on your notebook I?m afraid you must buy this recovery disc from Toshiba.

One more question: can you start HDD recovery installation as described on ?

Hey guys, so I was watching an anime the other night and all of a sudden my laptop just turns off. So I taught the battery died or something I checked if my ac adapter was plugged in and it was. So I retryed turning my laptop on but it doesn't turn on and only my battery light blinks a few times then stops. If any of you had the same problem and were able to fix or if you know what is wrong please tell me.

Thank you in advance.

Answer:Toshiba satellite L755 laptop crash. please help

First unplug AC and battery, hold Power button down for 30 seconds to drain resid power. Now put it back together and plug it in. What happens when you power up?

If it still won't start, unplug the battery and try again.

If these fail, try another power adapter of the same voltage. You can always take it to a shop or Geek Squad and they will plug it into their universal adapter which reveals if the adapter needs replacing.

Hi sir

I have Toshiba Satellite L755 laptop came from Finland in 2011. I use it last 4 years now and it worked fine but since few months ago power on and charging light has started to blinking some time it?s starting late or sometime its starting immediately.

Yesterday I changed battery and Ac adapter but the problem persists. I reset the laptop by removing battery and AC adapter, hold the power button for 30 sec butt nothing happened.

Answer:Orange light is blinking on my Satellite L755


On this virtual way it is not easy to say what is wrong there. If you are not able to start your notebook and all what happen is blinking LED, I’m afraid there is some problem with power supply electronic.

Blinking LED sends a code. This code can be read by technicians and using this code they can find out what the problem is. if there is some serious problem with board electronic I presume service will say that mainboard must be exchanged and it is pretty expensive.

upgrade from windows 7 to 8.1 ????

Answer:Satellite L755-1C7 - Windows 8.1 driver availability

Satellite L755 series was mentioned in the Win 8 upgrade list.

This means that Win 8 drivers are available on Toshiba EU driver page

Unfortunately, this series does not support Win 8.1 and therefore you will not find Win 8.1 drivers for this series. But Win 8.1 will work on this notebook for sure? in different cases you can also use the Win 8 drivers for Win 8.1 system

Answer:How to change boot order on Satellite L755-172


You can access the boot menu without changing the boot order in the BIOS.
Power up the notebook and press F12. Usually you should get an boot menu where you could choose the CD/DVD drive as booting device.

PS: I would recommend creating an Toshiba Recover disk firstly before formatting the notebook!

I would like to ask a help if there is anything I can do to have some much powerfull sound on my new laptop Toshiba satellite L755-1cd.

I've set the speakers to the loudest volume possibile but the sound coming from his speakers is very, very silent, so I can't listen to the music if I'm just some metres away from my laptop or when my friends are calling me on skype.

Sometimes I can't hear the calling sound if I'm not very near to the laptop. It has to be really quiet in the room that I can hear good the music or to talk to somebody on skype. The sound is not bad, just too silent.
It has onkyo speakers and I thing that they are not working good or the volume control is not settled properly.

Pls, let me know if I can improve the volume somewhere else that in his volume control (I've set the loudest volume) or can I check in somehow if my speakers are working properly.

Thanks in advance.

Answer:Satellite L755-1cd has very silent sound on his speakers

Welcome to the world of poor Toshiba on board sound, been a issue on most toshiba's models, in recent years, external amp and speakers your only option, but thats just my opinion.

I will try this in English, sorry for that ;)

A couple weeks ago, i use the Recovery tool from my toshiba L755-18E. All went fine, but suddenly, the "Data D:" partition had all the memory occuped (4,90 Mb available from 232Gb). I will try to upload the photo, i dont know if it will work:

My laptop is all the time sending a message that say: "Poco espacio en disco" that means that i have used almost all the memory of D:

I need to know how this partition (D:) came from toshiba, so i will know what folders i can delete, because i suppose that this is the problem.

Could anyone help me? Thank you and sorry for my english ;)

Answer:Satellite L755-18E - no free space on partition D

As I can see on the screenshot many ?Windows back-ups? are saved on partition D and every of them can be about 60GB. I have also created one but not more than that one.

Check a bit option for ?Back-up and restore? options in control panel. You can disable automatic back-up option.

?HDDRecovery? folder contains original recovery image that you got with your machine.

My Toshiba Sat?lite (L755-1NT, PSK2YE-0SM00CCE) works for about 20 minutes and then it turns down inmediately. First I thought it could be a overheating problem, but after monitoring the temperature with Core temp, the CPU temperature was OK (about 55?). In fact, it doesnt seem hot if you touch it.
When it turns down AC power LED stays white, but Battery light and ON-OFF light blink orange simultaneously.
Generally before turns down, the ventilator accelerates, but I am not sure if it is a real symptom.

I need your help please, because this computer is turning me crazy. Thank you for your help.
