Strange keyboard issues on Satellite M40

My Toshiba M40 has been giving me keyboard problems quite frequently. I get funny characters like NB¬A
when I press the left Shift key and then the keyboard starts behaving abnormally:
1. it shifts to caps mode -- to type lower letters, I have to actually use caps lock.
2. I can't use the shift key to type in the special characters above the numerals.
3. clicking on the menu bar gives me a different effect as if the shift key is already pressed while it is not.
4. pressing the right shift key takes me to the 'save' option.
5. I can't select one file or folder as several of them selected at one time.
And then I give up, shut down the computer (it doesnt restart at this time)
After some time, the computer starts normally but I am never sure when it will start misbehaving again.
I read about bios update, so got mine updated to the 1.7 version from toshiba website (this is the latest one they had for machines with ATI graphics).
sometimes, i use an external keyboard when the problem occurs repeatedly.
would appreciate advice on how to overcome this software / hardware problem.

Hi Ashok,
It is not easy to say what is causing this strange behaviour, especially since it also occurs with an external keyboard. One clue is that the notebook will not restart after you shut it down unless you leave it for a short while. This would suggest that the unit is overheating and this may well be affecting the unit causing your problems.
I suggest you try giving the notebook a good clean to remove any build up of dust and debris from the CPU heatsink.
regards,

Strange keyboard issue on a Satellite P300

Hi,
Since a week i have a problem with my keyboard on my P300.
The keyboard doesn't work when the power supply is on. The keyboard is inactive on vista and in the BIOS.
When i cut the power and the PC is on battery the keyboard is OK.
Do you have any infomations about this problem ?
Thanks.
oliv

Hi Oliv
Such issue is not known to me and I think it must be hardware related issue.
What you can do about it? Not much except to try with BIOS update but I dont think it will help.
Satellite P300 is not the newest notebook model. Since when you have noticed such strange keyboard behaviour?
To be honest I think you should contact Toshiba service in your country. Let them check keyboard and keyboard controller using diagnostic tools. They can tell you what the problem is and how to fix it.

Keyboard Issues on Satellite A505-S6973

Goodday again everyone,
Can anyone tell me if the onboard keypad on my Satellite A505-S6973 has a backlight.
I'm watching alot of these new laptops and similar to mine, under the keypad it's white and I'm not sure if it's like that because it's supposed to light. If so, can anyone tell me.

On Toshiba US support page I have checked notebook specification and obviously your notebook doesnt have this illuminated keyboard.
Just for info: all illuminated keyboards have FN+Z option for enabling/disabling illumination.
With other words small keyboard symbol will be placed on Z key.
This option, when illuminated keyboard is in the notebook, is also available in Toshiba HWSetup tool.

Strange keyboard issues with my 2012 Macbook Air...

Hey guys,
I've been using my brand new macbook air for the last 2 weeks or so without any issues. Today I took my laptop out of my bag after work and noticed that things on the keyboard have been really weird. For starters, certain keys on the right side of the board are not giving me the correct symbols when I press them. There are a few other random keys (mostly the numbers and symbols) that are incorrect.
ie: I press shift+2 for the @ but I get ' instead or I press ] and get @ instead.
Another weird thing to note: Caps lock turned on = lower case letters and Caps lock turned off = upper case letters.
I left my laptop alone for a few hours and when I came back to it later, whenever I turn it on it automatically boots into safe mode which makes me assume that the shift key is stuck in some weird way.
What can be causing this?

I have about the exact same problem, my macbook air 13 in (bought january this year in Belgium) is having the same issues, first (i'm on an azerty keyboard - first the following keys stopped working ; . : / and a week a half after that almost the whole keyboard gave up, symptoms
lowercase c reacts like the enter key
lowercase v types ^V
the whole row of keys from a tot Z don't work or produce garabage like ´^VVVVV1111111111
numerical keys work, but using shift together does not
If I attach an external keyboard, then the same key mismappings or whatever happening here, are also on the external keyboard, so I can't even login with an external keyboard
Sounds like hardware failure, but no idea why, my macbook is in top condition, no spills, no high humidty, really nothing whatsoever
If any one would have a clue prior to bringing it to mac store?
All defaults already done (smc - pram reset), reboot to recovery terminal there same problem with internal and external keyboard, boot from usb etc etc
For me really really really dissappointing, bought the top model macbook air with all upgrades available, as a stable working laptop for business use (for which I payed premium for a premium device) , but stuff like this happens on cheap windows consumer laptops, not on a macbook air
I have about everything over here, 2 Iphones, 3 Ipad's, an Imac, a MacPro, a Macbook Pro, each and every one of the durable and decent devices but this macbook air has been nothing to be excited about untill now, lots of blowing fans all the time, run's quite hot, the touchpad having it's on will
Always been a very loyal Apple customer as the list of Mac devices above shows, but things like this make me reconsider
Best Regards
Nico

Serious Keyboard issue on Satellite M70-267

The Keyboard Lanaguage Is United Kingdom. The keyboard is seriously messed up and I can't figure out why.
I can press any letter / number and it will give me something totally different, like for instance when i press space bar the screen resolution appears the whole keyboard is seriously messed up.
I have only had this pc for a week and it is brand new its a M70-267.
If anyone can help me resolve this issue that would be great.
thanks scott

Hi
You have suggested that this notebook is brand new. In this case you warranty should cover all replacements. In my opinion you should check if the new OS installation will solve this issue.
But if it doesnt work so you should contact the Toshiba service.

Strange Audio issue on Satellite L650/0FN

I bought a L650/0FN almost twelve months ago and have had trouble with an intermittent audio "buzz" in all audio file types and sources. The problem is now worse in that the "buzz" now appears to blank the screen and freeze the computer with the only way of shutting down being to pull the battery.
I found the following in a forum thread [http://forums.computers.toshiba-europe.com/forums/thread.jspa?messageID=235672&#235672] and thought it might provide a solution, but when i go to the intel download page the description for this driver is desktop chipsets and I dont find anything on my machine similar to Rapid Storage Technology Drivers so this may be a dead end. This driver seemed to fix a similar problem in the 0ED.
" Re: Satellite L650-10M - Audio/Video Lag
Posted: 06-Mar-2011 10:23 in response to: Bernz117
I investigated a litte bit and maybe you could solve this issue updating the iRST (Intel Rapid Storage Technology Driver) V10.1.0.1008.
But before you would do this, you should backup the data from the HDD.
I searched a little bit and the necessary driver V10.1.0.1008.or higher is available for download directly on the INTEL website under following link: http://downloadmirror.intel.com/19607/a08/iata_cd.exe "
Any thoughts or advice would be much appreciated. Thanks

Thanks As***,
By "Factory settings" do you mean the bios settings that came with the computer? To my knowledge those settings are all the same as when I bought the laptop. I haven't changed anything other than loading a few programs ie Word and Photoshop. (Im not sure how to check the bios settings on this machine (?)).
I Don't think i have experienced the "buzz" with headphones plugged in, but again, this is an intermittent problem.
I rang the toshiba service line but the fellow I spoke to wasn't much help unfortunately.
Sorry if my description wasnt very clear I'll try to expand on the problem:
The problem began with what can best be described as a slight audio delay or glitch, sounding like a loud "buzz" or "Brrrrrrr" that would last only a few seconds and replace the sound content. This would occur intermittently and unpredictably when playing various forms of audio (including movies and windows start up). At first I wasn't to bothered but the duration of the "buzz" has grown and then a few days ago it grew so bad the it seemed to kill the laptop screen, as it went blank and no command keys could stop it and thats when I had to pull the battery .
Im just getting a bit nervous as my warranty expires soon.

Hi
How long does this issue occur?
Did you install any 3rd party applications which could have a bad influence on this OS?
Well, if this issue occurs on a fresh recovered OS so it could be a something wrong with the keyboard.
I don't think that this issue can be solved without any experience. In this case you should contact the service.

Different issues on Satellite M40-185RU

Ah, yeah, g'day.
I have started having quite a few problems recently with my M40-185RU. It originally came with a Russian version of windows because it was purchased in Kazakhstan, but that was replaced when I purchased it with a licensed English version and then all of the drivers reinstalled. Now it has worked happily for the past 18 months, but recently more and more functions have stopped working, of which I sort of have blamed various Microsoft updates. I figured I would try and reinstall all of the drivers in the recommended order, then the updates and see if that fixed the problem, but it hasn't.
Problems I have had are, aside from various drivers wanting to download and install in Russian because I am in Kazakhstan:
1)The infrared port stopped working, but I found the quickfix download for that - it still hasn't fixed it. Plus the driver only downloaded in Russian. (trying to download off UK site).
2)The dial up modem has just stopped working and I get an Error 633 code, although no settings have been changed for my modem. I have tried reinstalling the updated modem software, but it still doesn't work.
3)Bluetooth Stack drivers only download in Russian. (trying to download off UK site).
4)Soundmax Drivers only download in Russian (trying to download off UK site).
5)Wireless LAN drivers only wanted to download in Russian, so I didn't bother updating them.
6)Nokia PC Suite wont connect with a USB bluetooth, infrared, or even a blimen cable connection. I have reinstalled this several times, restarted etc etc, but no joy.
7)DVD/CD rom will no longer burn cd's, or even dvd's through Nero, or even the simple "drag & drop" function of Windows explorer.
several of the other drivers also only wanted to download in Russian as well, but as they were not that important I skipped them.
So I guess what I am really after is if anyone has any ideas on how I can fix my otherwise great notebook. While I would love to get everything fixed items 1,2,6 & 7 are the more important ones for me.
TIA everyone.
Keiran

Okay, I have managed to get the modem working again but uninstalling the modem software, uninstalling the nokia PC suite software, restarting, then reinstalling the modem software. So thankfully no more 633 error message on that one.

Strange burning issue on Satellite A100

Hi!
I just stumbled on a curious problem. When I burned a DVD with Nero, it worked fine. The 2nd one worked but after playing the movie for about 38 minutes the movie just stops playing and the light on the DVD burner lights up consciously. I've already tried reburning the movie and burned another one but both stop playing after about 38 minutes (burned them with another computer and burner: the movies worked).
But then I notice a lot of errors in the windows log:
Damaged block in device \Device\CdRom0.
And another thing I noticed: the DVDs were burned at 6x, not the 8x speed the burner of this laptop supports.
Does this mean the DVD burner is broken?
With regards,

Hi
In my pinion it usually caused by a scratched or damaged cd. Try to clean it and see if it helps. If it works fine with some disks then its not the drive.
Some drives dont accept every media. Many CDs and DVDs are not compatible and therefore the drive burns the files not properly on the CD or DVD.
You could check different medias for the similar problems.
One little tip: In the user manual you should find a list of compatible CD and DVD. I think you should try to burn files or movies on one of the mentioned medias. Possibly it will work.

Satellite M40-133: startup issue after shutdown

When shutting down my Satellite M40-133 EN if I start it up again all I get is the Toshiba wellcome screen.
If it is left for some time it will startup as normal. When running it is quite warm.
Please help.

For me it sounds like an issue related to the overheating.
It seems the notebook cannot start and boot properly due to a high internal temperature.
The main reason why a overheating issue happens is very simply.
The cooling modules dont work correctly. I think the dust and debris prevent the cooling fans from running with full performance.
A simply fan cleaning should help you.
From time to time I clean my ventilators too. I use a compressed air spray. Such sprays are very useful to get rid of dust and most computer/notebook dealers offer such sprays.
If it will not improve the situation then a notebook technician should disassemble the notebook and should clean it properly. Additionally he should renew the thermal grease which is placed between the CPU and cooling module, too.
Good luck

Satellite M40-237: CD Boot not working + is USB flash drive boot possible

*Model: Satellite M40-237 (PSM40E)*
I decided to reinstall windows, my hard drive is currently formatted. So as usual, boot from Windows CD is needed to start instalation but it simply won't boot. I never had problems like this, boot always worked. It is like there is no bootable CD in the drive (but it is bootable and it is working on another PC).
- i have the latest BIOS
- BIOS detects optical drive and everything is ok, HDD is primary ODD is secondary
- i tried selecting boot priority with F12 and/or setting it from BIOS, but it won't work either way
What could be the problem here? Drive not working properly (i hope it is that and not something worse)? I had some problems with the drive i before (writing...), but it reads CD/DVD's normally and like i said boot was working fine before. I cleaned the lens a little, disconected it and put it back. Is there anything more i can do ?
I am trying to find someone who has the drive that fits so i can try with that one, but who knows when will that be.
Now, here is the second question i have related to this. Because my laptop is practically useless currently (i can't install anything), is it possible to boot from:
a) external USB optical drive
b) USB flash drive
Bios on this laptop has no USB boot option, it has HDD / CD / FDD / network. But I've red somewhere that FDD = USB if legacy emulation is enabled.
If that is correct i should just plug the USB drive and select FDD as boot option ? If i can't find USB optical drive, i was thinking of making USB bootable flash disk and copying windows xp installation on it. So once it boots into DOS i just start setup from the stick.
tnx

First of all I have to say that the booting from USB flash memory (USB stick) is not possible and you shouldnt waste the time trying this.
Regarding your CD/DVD drive booting issue
Well, its really strange it sounds a little bit like a kind of master/slave/c-sel settings issue. But usually you should get a IDE (#0 or #1) error if one of the devices (HDD or ODD) would be not recognized ?:|
The whole story sounds mysteriously
Maybe there is a firmware issue
Several months ago a friend of mine was not able to boot from the CD.
He entered the BIOS and set the BIOS back to the default settings.
This helped
This is a suggestion but I really dont know if it helps.

Satellite M40-256 - error while booting via CD

Hello,
a well-known friend owns Satellite M40-256 which has Windows problem (error while updating/handling by her children).
She doesn't own an external Toshiba FDD or ODD. Also this portable has no built-in FDD. Buying one only for this issue? NO
The boot priority has been changed to: CD-network-HDD.
I've tried another non Toshiba branded ODD (in BIOS not mentioned/found)
The original ODD works/boots in another pc (via adapter) very great.
Ive tried several CD/DVDs to boot from (no error displayed): instant-Linux like knoppix, suse, other windows CDs, recovery CD, ... no success
Every time the same result: the laptop has a black screen, the ODD speeds up and after about 3 to 5 seconds windows starts with the black-white progress bar.
I also tried to press C to force booting from CD.
Some time ago, I had only access to windows in secured mode. But after uninstalling some updates it ends in a licence problem. This issue can be only solved by booting windows-cd via cd.
It has a Toshiba bios 1.00 (interesting, seems quite old).
I've trying at the moment to boot via network. Does the Toshiba show some messages about succeeding/failing at boot via network or CD?
Has setting the execution bit an influence on behaviour?
Does anybody know a solution booting windows?
Thanks in advance

Thanks for help.
I will look for an other ODD from Toshiba trying for boot.
Does the toshiba bios show messages about booting via cd or network? Even choosing network ends in a faulty Windows boot.
After choosing an item there's no message while booting
As I mentioned: the most interesting issue is ODD works/boots well via adapter in a normal pc and also after windows has been started (secured mode). But no boot possible.
I suspect meanwhile BIOS or Mainboard. But is there a chance for update in secured mode? (the only thing it starts is "secured with prompt"). Cats bites itself in tail.
BIOS also was saved with default setup. Nothing changed.
In event viewer I've found entry about probs with hard-drive and controller.
Does a destructive data processing influence the toshiba bios

Satellite M40-145: CD/DVD drive won't read some DVDs

Hello!
I own a Satellite M40-145 purchased just over one year ago; the DVD driver worked perfectly until three days ago, but today I discovered something... peculiar. It still reads commercial DVDs and burned DVD+R, but apparently it doesn't read burned DVD-Rs anymore. I have tried with different DVD-Rs I burned through the same DVD player, with no success; trying to access the DVD yields a "insert disk in D: drive" message.
In this case, I'm talking about movies on DVDs. Please tell me there's a way to solve this without sending the computer to customer service...
I'd hate to think it broke down just days after the expiration date of the warranty.

Hi
Well, you can try to remove the drive form the device manger.
After new reboot the drive should be recognized again. Check then if its possible to read the DVD-R CD.
But the issue sounds as a lens calibration error. If you use different media the lens must be calibrated again. But if this procedure fails, the drive is not able to read or write the DVD for example.
Unfortunately, in such cases only the drive replacement will solve this issue.

Satellite M40: Graphic Errors when changing screen resolution

Hi,
I have a Satellite M40 and a big problem.
in windows xp pro sp2:
when a program changes the screen resolution, the screen gets messed up,
I see only stripes and only a restart can get it back working (or suspend to disk).
[edit]
I plugged an external monitor to the laptop and it works,
the laptop screen is full of lines and the 2nd monitor shows what the laptop screen should normally also show
[/edit]
in linux:
this can be also seen when changing from the xwindow mode in linux back to tty(1-6)
Here are some pictures of this strange behavior:

http://www.ronnylindner.de/extern/images/toshiba/screen2.jpg
http://www.ronnylindner.de/extern/images/toshiba/screen3.jpg
It looks like a hardware problem, but could it be just a wrong bios setting?
What can I do?
Bye and thanks in advance, Ronny

I will try it with the Toshiba graphics driver, at the moment I use the newest Omega driver
I use 1280x800 as normal resolution
programs giving this error:
world of warcraft (1024x768) -> working with 1280x800
age of empires 2 (800x600)
as I said before, I get this problem also using Suse Linux when I switch from KDE to tty
thanks you too, hope we can get it working together :-)
[edit]
strange, using the Toshiba display driver I got the problem at the first try (aoe2), but now it is not reproducable :-(

Satellite M40 - SD card stuck in SD Card Reader

Hi!
I have a Satellite M40 and today I had the bad idea to use the Toshiba SD card reader.
I inserted the card into the slot and it went deep into it. Trying to get it back only resulted in pushing it farther in.
Now the cards is aprox. 2cm inside the slot and there is no way to get it out.
This must be a joke. Please tell me where the secret button is to get that card out of there. I give up, really...
Thanks,
Fritz

Hello
As far as I know Satellite M40 has not SD card slot but media slot and it supports different media cards. Of course you can not use all cards available on the market but just supported formats.
Zim wrote very good explanation how it works. Of course, with compatible cards only. Described issue can not happen with SD card. It is too big and can not come 2 cm inside the slot.
I am afraid you have used mini SD card. Am I right about that?
This card can not be used without proper adaptor.
Bad thing is that there is no secret button. :(
