Satellite L300 1BD - VGA output is not working

Hello.
I have a Toshiba Satellite L300 1BD (Model PSLB8E). I was usinng the VGA output to connect to my LG tv. It worked fine until last week. All of a sudden the TV doesn't get reckognized by the laptop anymore. The TV says that no external device is connected. I have tried different things: starting up with the TV connected and not connected through the VGA cable, pressing the FN+F5 button, removing the battery and pressing the powerbutton, checked for the latest videodriver, removed the existing driver and installed it again...unfortunately without any result. I also tried to hook the TV up with a different VGA cable, but no result. It's not the TV, because i did try to hook the laptop up to a TFT monitor and it didn't work as well. Tested the VGA cable with my friends laptop: it works perfect.
The strange thing is: if i hook the TV up to the laptop, i can hear the laptop is making the 'new hardware detected' sound and the laptopscreen even turns black for a second, then everything appears back on the laptopscreen. If i check the graphic properties with the rightclick on my desktop, i can see that they are no set for 'clone device'. As if the laptop knows, something is connected, but just can't transfer the image to the TV screen.
The graphic adapter is a Mobile Intel 4 Series Express Chipset family.
The OS is Vista Home Basic (32).
It's a shame the VGA output seems to be out of order since i watch tons of video's and movies through my laptop on the TV screen. I don't know if this could be a software or a hardware malfunction. If anyone has an idea or some clue, please let me know. Thanks in advance!

Hi,
I would like to give my 2 cents to this post (and the answers from Toshiba):

I have exactly the same L300 19F with the same graphic adapter, only with Windows 7 Ultimate (32) and was watching DVD's through my Toshiba TFT TV-set/VGA Monitor for a couple of years as well as all of a sudden it doesn't work anymore. The same as the gentleman who started this thread I checked everything there is to check: my laptop/another screen, another laptop/my screen, drivers, new cable, even installed the (original and licensed) W7 OS again etc. etc. etc. TO NO AVAIL !!!
Since this is the first time that I can't solve a technical computer problem in more then 25 years I got mad and started to think what the heck I did different over the last few weeks, and now I think I know the culprit.
One day, a few months ago, I saw a warning in my screen to flash my BIOS with a new upgrade from the Toshiba website. Having seen that message for several months I did not give it much attention because everything worked fine, and the reason given for the update was a quote "password protection update" unquote, a function I don't use anyway and that's why I didn't run that fast.
After a while I decided to flash the BIOS, just to get rid of the annoying message and now I am quite sure that it really did kill my VGA output capabilities.
So, instead of the nice "Check your Power Cord" and "Go to the Official Toshiba Dealership" hints, maybe there is some technical solution. Maybe there might even be a nice technical Toshiba person have a look into the BIOS update and what the heck the differences are with the old one.
At the very least you could offer a "downdate" of the current valid BIOS for this type, because everything used to work pretty good and, as a 25 year long time customer of Toshiba laptops, I could be entitled to a little better (quality) answer.......
My friend Marcinondrums and I still have hopes.
Thank you !!

Satellite L300-055 - VGA output doesn't work on external TV

First I will give you my Laptop Specs: Toshiba Satellite L300-055 series laptop bought January 2009- 2GB RAM upgrade- Intel 4 Series Chipset Family
Okay, I recently purchased a wire/connector like Link: [This One|http://www.vista24.biz/ebay/tpschc/v2b27214c.jpg] and when I plug it in to my To my vga port and the other end to the tv (via RCA) and follow the instructions by turning off my laptop then turn on the tv then turn back on the laptop- but NOTHING shows on the tv.
The cable is working perfectly well. When I press fn+F5 it still only shows that no external monitor is plugged in. Do i need more drivers? Does my laptop not support tv-out. If not- is it possible to install a S-video port onto my laptop?
Thanks

Hello
Have you tested both connections possibilities? I mean the S-Video port and the Chinch?
If you have connected the laptop to the TV, shut down the notebook. If the notebook is powered off, switch on the TV and then notebook.
Then you can normally switch between the monitors by pressing FN+F5.
Furthermore its not possible to install an S-Video port on your laptop.

Satellite L300-1bd LCD backlight does not work properly

Hi,
A few days ago, the backlight of my l300 stopped to function properly.
I have tried turning it on a few times, and sometimes it briefly lights up and then goes off again.
Any idea's on what my next move should be?
I called a repairshop, and the guy i spoke to told me they would charge 50 euro's just to open it and that he was afraid he might have te put a new lcd screen in which would cost me another 150 euro's. I cannot afford this, nor do i think it would be a smart move to do a 200 euro repair on this notebook..
now because the backlight went briefly on and then off, i am kind of hopeing the cable that connects the screen to the computer might be broken/not plugged in properly. I found a repair manual which makes me think i can change it myself, but: is there a way i can make sure what the defect is before trying to plug in a new cable? what kind of cable do i need, and where can i get this?
hope you guys can help me out!

Either its just a FL inverter issue or the display fault
The FL inverter controls the display backlight and therefore I think its FL inverter.
This is a small part hidden behind the plastic display frame.
I dont know ho much is it but its not very expensive like display itself.

Satellite L300 - 'W' and 'F' Keys not working - can't log

Hi,
I have a Toshiba Satellite L300.
My 'F' and 'w' keys arent working, and because I have a Built-in HDD user password of which contains those letters, I can not start up my computer.
I had a 'startup' problem a couple of months back, and what I had to do was restore my laptop to a previous date. I did this through Boot management during startup. The only thing is I cant remember how to do it now.
I cant find any restoration disks that may have come with my laptop- so the only way I can do it is through boot management.
So, how do you do a system restore? or is there another way of fixing this problem?.
Please help!! :)

Hello
If W and F key dont work I would recommend replacing the keyboard or use an external one. In my opinion its the best choice because you also need the keys for typing letters or emails
You can get a new keyboard from an authorized service provider in your country.
> I cant find any restoration disks that may have come with my laptop
I think you should read the user manual because you have to create this disk yourself ;)

Satellite L300-147- Manual volume control not working

The manual volume control on the laptop is no longer working. If I try to adjust the volume (on the right the headphone plug-ins)- I just keep scrolling. As a result, I can only watch DVD on a really low volume level. I have adjusted volume control under "control panel" to the maximum level.
Any ideas to fix this please?

Hello
> The scroll for volume control on the laptop keeps scrolling on empty (it can't reach the end)
Believe me buddy, this is absolutely normal.
I have Satellite L300 too and I can still scroll the volume control although the sound is on lowest level (I can see this in Windows sound properties).
To be honest I didnt have any notebook as yet where the volume control ends on a certain point.

Satellite L300 - VGA output does not work

I am attempting to set up a media center via my Toshiba L300 laptop by connecting it to my VIZIO 37" LCD via the VGA (RGB) port to the component in the TV.
I connected it all up, but the TV consistantly says "no signal".
Is there something that I am not doing properly?
The control panel also says there is only one monitor installed on the laptop and I am told that there is supposed to be two installed as the TV serves as one of them.
Can someone shed some light on this for me?

I did however get it to work properly via a VGA (RGB) cable directly to the back of the TV. There is an input jack in the back of the television and it's working properly that way. I'd still like to use the component cables though if possible due to rendering better quality. Thanks again.

Satellite L300 - Hot key function is not working

After the superb help I got from Jimi I'm hoping I can solve my last problem, I have changed my OS from Vista to WXP and I have managed to get all drivers working even though some from the Toshiba site dont work like the Wi-Fi, I have managed to acquire from other places. The only one I cannot get to work is the hot keys , It states TOSHIBA COMMON MODULE NOT FOUND! Everything else works o.k. after using Nlite (Cracking Bit Of Kit)
My Laptop Is the Sat L300 - 1AQ Model PSLB8E-OOKOO
Many Thanks for your Help

Hello
Ivan is right. You must install Common modules. It must be installed at first before you start to install any other Toshiba designed tools or utilities.
Common Modules is kind of basic software and all other tools can be installed additionally. Because of that it is very important to install Common Modules first.
Good luck!

RH 5.5 output does not work properly in RH 7

I inherited a WebHelp project created in RH 5.5. I have RH 7.
When I open the files, make modifications, and recompile them, the
output does not work properly once I put it on our hardware box.
Those infamous red squares are present and there seems to be a lot
of .js files being called, but even when I do a straight 1:1 copy
and include all the files, and delete the red squares, it still
doesn't work right.
Also, oddly, when I open the original (5.5) files in my v7 --
even without making ANY changes at all -- the TOC has
disappeared.

When you view the upgraded source files in RH7, are the red
squares seen the editor?
When you generate to a local folder and view the output
there, are the red squares present? Are there any other issues with
the generated output?
Have you applied all three patches to RH7? Help About should
show 7.0.3.

IPad audio output is not working properly, except on Siri. Any ideas on what is wrong and how to fix it?

iPad audio output does not work, except for on Siri. The mute button is not on, and the volume buttons have no effect/ don't work (unless Siri is open). I have reset the iPad, tried iOS7 and iOS8 resets, which didn't help. The audio output mostly works when headphones are out in, but has a tendency to cut out from time to time. Without headphones, Audio might start working again briefly from time to time, but most the time it doesn't. Any ideas on what is wrong with it and how to fix it?
my iPad is a 3rd gen, 16GB wifi only model, if that helps
I did take it to an Apple Store, but the inncorrectly insisted that my speaker was bust and it would cost £250 to replace the whole iPad!

iOS 8 isn't even out yet. If you are running iOS 8, I assume you are a developer and if you are, you are in the wrong forum to try to get help. If you are not a developer and you're running iOS 8, maybe that's why you are having problems on the iPad.

The type that I made bold doesn't make sense. Is this a typo and you mean that " headphones are not in"?

And you know they are incorrect because you get sound here and there from time to time? That fact doesn't prove that something isn't working correctly inside. You could very well have a bad connection inside the device causing this, but somehow you seem to know that's not the case.

Satellite A210 (PSAELE) - VGA output not working

Hello everybody,
i've got an A200 PSAELE and I am trying to connect it to an external Monitor via VGA.
The external Monitor is a Medion 19" Widescreen with a Resolution of 1440x900.
The problem is, that I am not able to get the external display to work.
I just get a "no signal" message on my external monitor.
I tried various things, tried another VGA cable, another monitor (Benq FP93G X) and another driver.
I am using Windows 7 Beta ans also tried to get it to work using Windows Vista Home Premium & Windows XP.
In the "resolution settings", I tried using the "recognize displays" button.
When i use it, there is a second image of a display displayed like a box.
In this box, there is the following text: "Antoher display couldn't be recognized".
Regardless of the settings I use (clone, span, ...) I can't get any image onto my second screen.
I tried changing some BIOS-Settings without success and made a BIOS-Upadte to Version 2.00, same problem.
I also tried switching to the external monitor via "Fn + F5", but nothing happens onto the second screen.
Can anyone help me?
Thanks in advance,
StarGeneral

Hi,
I tested two more things:
-> I downgraded to the Toshiba Windows Vista Home Premium 32bit drive, which works on Windows 7 as well. There in the Catalyst Control Center I've got the "Displays Manager" section, which I don't have with the release drivers.
But even there, when I click on "dectect displays", nothing happens.
When I press the Windows-key and "P", a display opens, where I can select how to use the external VGA out, but when I e.g. select "clone", the resolution on the laptop-screen changes, but there still is no signal on the external monitor.
-> I tested the laptop with a real CRT analog monitor, but I didn't get any further.
But I have got the sneaking suspicion, that I've got a conflict with the HDMI / VGA version of the A210 laptop.
I know that there are a few laptops with an HDMI output and a few with a VGA output.
I checked my audi-devices and found an entry named "HDMI-Audio-Out".
Isn't that strange, because my laptop doesn't have HDMI connector?
Probably I've got a Mainboard/Graphics-card combo, which has got a HDMI port and no VGA output and which was designed for a HDMI-A210?
Could something like this be possible?
Thanks in advance,
StarGeneral

Satellite Pro U200: VGA output not working properly when AC adapter was connected

Hi,
I have a problem with vga output. When I'm working on battery and connect my notebook to external monitor it's ok, but when I connect AC adaptor then start waving also bluetooth and wlan does not work properly. In other case when I remove battery from notebook and connect AC adaptor it works properly.
thanks in advance

As long as you use a CRT you should set the refresh rate new, at least 85Hz. Standard is 60Hz as far as I know, and that hurts in your eyes.
The wireless lan behaviour is quite normal as long as your not right next to the access point. On battery power the wireless lan card reduces its energy consumption thus the connection will be poor if you dont have a perfect signal. You can turn this off in the iNTEL Pro/SET wireless software, where you can configure the adaptor. Try to change the powersafe mode to manual and full power, this should solve your problem.

Satellite L300 - Built In webcam suddenly stopped working

Hello,
I have a Toshiba Satellite L300 with a built in 2.0 USB camera and a windows 7 operating system, the camera suddenly stopped working since about 2-3 weeks ago with unknown reason!
I already tried system restore, un-installing and re-installing the camera driver, preformed a full scan by kaspersky internet antivirus 2012 (up to date), and I also ran a complete system and drivers troubleshooting ... and the problem still exists ...
When I use the windows live movie maker it gives me an error saying: cant record audio or video from the selected device. Make sure that the device you're trying to use is installed properly and not currently in use by another program.
The microphone works well on skype but the camera doesn't open!
Please tell me how to fix it, what am I missing?

> webcam appears in the device manager
Is it marked with an yellow exclamation mark?
Usually if the webcam software has been installed, you should be able to start this software going to:
All Programs -> Toshiba
There you should find the webcam software check if you can use and control the webcam after this software has been started normally the webcam control bar should pop up if you would move the mouse cursor above the upper display area PS: the bar can be moved to other area too; left right or bottom

How to activate Intel Speedstep on Satellite L300-1BD?

Hi,
today i bought the Toshiba L300 - 1BD Vista is preinstalled.
To enhance my batterylife, i changed vista to "classical design" and the energy option to "power save".
Although it doesn't use Intel Speedstep technology.
When I run the utility: CPU-Z, it shows that the CPU Speed is on 2000 Mhz. Normally, when the CPU is idle, it should change the multiplier to low, which shout result in about 1000mhz. This saves much battery!
Does anybody know, why it is not working, or how to get it working?
Thanx and Greetz from Germany!

Are you sure the CPU supports the Intel Speed Step technology?
I googled a little bit and it seems that this unit was equipped with the Celeron-575 (Merom-2.00GHz) 667MHZ CPU
And Im 100% sure that this CPU *DOESNT* support Speed Step.
