Re: Smoke Comes out of my Satellite Pro A300

Toshiba Satelliet A300 Pro PSAGCC-06H019
Within the last few weeks when I raise the LCD screen from closed position while in hibernation mode the screen will not start up. That is load up the start screen with user profiles. All the LED lights are on and I can hear the fan working but the screen remains blank.
I noticed that when the screen is 90 degrees up, and I move it slightly further back it then "wakes" the computer from hibernation mode and it starts. It seems like a "switch" which is supposed to perform this function isn't working correctly where the LCD lid attaches to the keyboard base.
Two times now while trying to turn the computer on smoke has come out of the right and "joint" while performing the above action. The first time it happened I immediately pulled the AC adaptor plug. Thinking it was fried I started it back up and suprisingly it worked fine. There doesn't seem to be anything wrong with the laptop other then the smoke and the issue with not starting correctly.
Any suggestions ? Its well past warranty.

> Any suggestions ?
My suggestion for you: dont make any experiments with your notebook. Dont switch it on anymore and contact nearest authorized Toshiba service provider as soon as possible.

Satellite Pro A300 - Overheating

Hello,
It has been a year and a half since I got my Satellite Pro A300. Just a week ago it started overheating very badly. At low CPU usage it maintains its regular temperature of 55 - 60C (given the hot summer weather).
However if I try to do anything CPU heavy, the temperature gets to 100C in a matter of minutes and the laptop shuts down. The fan is working, except that it does not seem to generate as powerful air stream as usual, which made me think that it was clogged. I disassembled the laptop, but I could not get to the cooling unit because of the three cables connecting the motherboard to the plastic shell, which have white T shaped connectors that for the live of me I could not pull out even a little bit. Nevertheless, I cleaned what I could with compressed air, and a little dust was cleared, but the fan/radiator did not look clogged at all.
After putting it back together there is no noticeable difference.
I am certain that this is a new phenomenon as I've been running the machine in much hotter weather in worse conditions with CPU loads close to 100% with no trouble. I checked all settings, just in case something had toned down the fan, but the power saver utility is set to "Maximum Performance".
I would appreciate any ideas and help, even just tips on how to disconnect the motherboard cables.
Thanks in advance.

Hi buddy,
I agree with the user above: Cleaning procedure from time to time is really important and if compressed air spray doesnt help it must be done by professional people from an authorized service provider. They can disassemble the whole notebook and clean every part well. You can find a list of service providers here:

Notebook disassembling is not easy so it should be done from professional people. Just ask the guys for help ;)

Satellite Pro A300 crashes with blank screen

I have a Satellite Pro A300, AMD CPU, ATI graphics, Vista.
The system worked fine for a year but a few months ago it started crashing, the screen went blank, not blue, anything running, like music, stopped. This can happen after several hours or minutes, or even whilst it is re-booting. All my software is up-to-date, both from Microsoft and Toshiba. I have rebuilt my system from scratch and the symptoms came back.
At first I thought this might be a heat problem but I have monitored this but I don't think this is it. It has crashed seconds after leaving sleep mode when it has not had a chance to warm up.
Anybody got any ideas?
Simon

Hi buddy,
Theoretically it could be an overheating problem so the screen went blank due built in overheat protection...
You should try to clean your notebook using compressed air spray. This could blow out the dust from the cooling ventilators and therefore its not necessary to disassemble the notebook.
In your case I would recommend reading this article:

Re: Satellite Pro A300 - DVD drawer does not open most of the time

I have a Satellite Pro A300-1NH laptop. The DVD drawer does not open most of the time. Occasionally it does, but most of the time it does not.
Sometimes if I manage to get a DVD/CD into the drawer to burn something to, the burn works.
Most of the time the computer does not recognise that there is a disc there, and then I can't open the drawer again to get it out.
Can anyone tell a novice what I need to do to sort this out please?

Have you noticed this when you try to open drawer using eject button in the drawer itself?
Almost every player has integrated eject button. Can the drawer be opened using this eject button?

Satellite Pro A300 - FN Key not working with xp downgrade

I have just purchased a Toshiba Satellite Pro A300 and downgraded the o/s to XP.
There is a problem with the FN key on the keyboard, it does not function. I dont know if this has something to do with the xp downgrade?
Any ideas please?

If you have downgraded to Windows XP with the Microsoft disk you must install the Toshiba utilities and Hotkey Utility.
This is necessary for the FN keys in Windows XP so check the Toshiba website for these utilities:

Cooling fan is not working on Satellite Pro A300

Hi Everyone
I was asked by a friend to repair their Satellite Pro A300, as their CPU Cooling Fan had stopped working even during POST bootup and the laptop would overheat and shutdown. So I thought it could one of three things:
# Fan is clogged with dust or dirt
# Fan bearing has failed
# Fan power cable was loose
So I disassembled the laptop and cleaned the fan/heatsink using compressed air and checked the power connection which was solid, but this did not solve the problem, so I replaced the fan and heatsink with another one that I knew worked from the same model laptop that had a fault motherboard because of the random bios boot-up password bug (out of warranty) but still no joy.
I am beginning to believe that the fan was perfectly fine rather the motherboards cpu temperature sensor(s) that control the fan activation has failed.
Am I correct, in thinking that this is basically, irreparable without specialised tools and my friend will have content themselves with turning the system off every hourish or is there something else I am overlooking?
Thank you, for any help.

Hello
Im not a technician but for me it sounds like that fan connector is malfunctioning if you have already replaced the fan and therefore it would be necessary to replace the mainboard
Thats everything what I can say about this Have a look for second mainboard or notebook where you can get a cheap mainboard. Maybe it works. :)

Satellite Pro A300-1A8 Vista system restore not working

I wanted to use system restore due to attempting to reconfigure administrator rights, its somehow deleted all my shortcuts on my menu and messed about with a few things.
However when i try to use system restore (i have attempted to use it in safe mode, via cmd promp, both together and normal boot), yet all seem to stay hanging in the same green page where it reads something along the lines of 'system is initialising restore etc' (spending 45 mins on this page before i get fed up and shut down the computer). I have tried using different restore points but the same occurs. It like its not working at all.
Can anyone help with this please?
My laptop is a Satellite Pro A300-1A8.

Hi
You mean the Vista tool which can be found in (Start button -> All Programs -> Accessories -> System Tools -> System Restore) does not work and you cannot set back the Vista to the early time point?
Well, usually there is no much to do to restore the OS to the early time point you have to star the system restore tool and have to choose the restore point. Then everything should run automatically.
If this doesnt work then something is messed up as you said in your posting above somehow deleted all your shortcuts on my menu and messed about with a few things possibly the OS has been messed to.
Try to clean the OS using the free software for example CCLeaner. I use it too. Its great. Repair and clean the OS and check if its possible to use the system restore tool again.
I found also this MS page:
[System Restore: frequently asked questions|http://windowshelp.microsoft.com/Windows/en-US/help/517d3b8e-3379-46c1-b479-05b30d6fb3f01033.mspx#EIEAC]

What CPU would work on Satellite Pro A300-2C2

I know far more about desktop computers than I do laptop computers,
However last night my laptop completely froze and held the current sound (making a kind of buzzing sound).
I thought nothing of it at the time however it wasn't coming responsive again so I held down the power button and went to sleep. When I awoke this morning I booted up my laptop, but it did not boot.
The motherboard is not broken as it is givin power to lights and disc drives ect...
I am basically wondering what CPU's will work in the a300 2c2,
I HOPE it isn't soldered in but I have not confirmed that yet as I have to go out in a moment, thus I cannot open her up.
Thanks in advanced,
TheUnknown

> I am just wondering if you know if/where I can find a list of CPU's that were used in the A300 over time, I am thinking if they were compatable down the line mine should accept it, right?
Indeed, the usage of the same CPUs which were used previously in other Satellite Pro A300 should be possible.
I read somewhere in the internet that Toshiba Satellite A300 /Satellite Pro A300 and Equium A300 are similar series and used CPUs should be compatible.
The chipset seems to handle the Penryn and Merom CPUs.
_Penryn CPUs are:_
Intel Core2 Duo Processor (800MHz)
T8100 (2.20GHz) / T8300(2.40GHz)
T9300 (2.50Ghz) / T9500(2.60GHz)
_Merom CPUs are:_
Intel Core2 Duo CPU (800MHz)
T7800 2.6GHz
Intel Core2 Duo CPU (667MHz)
T5250 (1.50GHz) / T5450 (1.66GHz)
T5550 (1.83Ghz) / T5750(2.00GHz)
Intel Pentium Dual Core CPU (533MHz)
T2330 (1.60Ghz) / T2370(1.73GHz)
Intel Celeron CPU (533MHz)
540 (1.86GHz) / 550 (2.0GHz) / 560 (2.13GHz)

Satellite Pro A300 PSAG9E. Should I keep it or not?

Hello
I have just bought a Toshiba Satellite Pro A300 PSAG9E. It came pre-installed with Vista, and also an upgrade DVD to windows 7 professional (which I have installed).
I tried starting up the machine this morning, however for some reason it wouldn 't boot. All that happened was that the initial toshiba screen would appear, followed by a frozen black screen (showing an underscore in the top left corner).
The thing is that I seem to have been able to solve this issue, but I just don't understand how/why this happened!
The issue seemed to be related to the battery. At first I was trying to boot the laptop (with only the battery connected) however it would not start. I dont think this has anything to do with the amount of charge in the battery, as it did have more than enough in it. I then tried booting it with just the power cable (and no battery). For some reason this seemed to do the trick, and the laptop was able to boot. The laptop now also boots when both battery and cable attached.
Why is this happening?
The reason I am interested in finding out, is because this laptop has given me a few problems already. The laptop has also been bought very recently, so I can still return it for a refund (which I am seriously considering!).
What should I do guys? Any help/advice you could give about this would be very much appreciated.
Thank you
Jay

>All that happened was that the initial toshiba screen would appear, followed by a frozen black screen (showing an underscore in the top left corner).
The blinking underscore in the left corner means that the BIOS battery was empty or something wrong with the HDD (possibly BIOS didnt find the right booting source)
I recommend accessing the BIOS and to set it to the default. Save the changes and try to boot the unit again.
You should also keep the notebook connected to the mains for about 24 hours and the notebook should be ON as well.
This will help to charge the CMOS battery.

Satellite Pro A300-28R - Windows starts up with wrong display resolution

OK so I have a Toshiba Satellite Pro A300-28R with Windows 7 64 bit and an ATI Mobility Radeon 3470 HD graphics card.
I recently connected my laptop to a TV via the S-video connection. This worked fine. The problem is that ever since then every time I start my laptop Windows starts with the S-video display resolution of 600x800.
I have tried changing the settings in both Control Panel and using the ATI CCC, having both selected and applied these settings but each time Windows starts now it boots with the above display resolution.
Following this I have also uninstalled and reinstalled both my display driver and the Toshiba Value Added package but the same problem persists. I have searched with Google about this problem and haven't been able to find anything useful.
Any help would be greatly appreciated.

Hi thanks for your responses! Originally I used the method of closing the laptop screen while connected to the s-video and then opening the screen and logging into Windows. This then automatically detects the display and changes to that output. To get out of this you can do either do the reverse or pres Fn+ F5 to undo. This has worked perfectly for me before with VGA connections. Its only since connecting to s-video that now no matter what, every time the laptop starts up even when it is not connected to any external display, it loads with the resolution 800x600. This is not the first time I have used s-video, but it is the first time I have had this result after doing it.
Interestingly if I change to the appropriate resolution and do a restart. The system restarts and loads to the logon screen and then into Windows in the resolution I specified before the restart but then after fully loading Windows it then changes to 800x600. It is as if the laptop is detecting that there is something connected to the s-video when there is not. I have read a fix for this whereby you can go into the system registry and turn off the feature for automatically detecting displays but I use external displays frequently and this is not a satisfactory solution. This worked perfectly before.

Satellite Pro A300-28R: slow boot and freezing on Explorer/Internet

I have recently bought a Satellite Pro A300-28R and I am quite disappointed about the performance.
1) From the specs it looks like a decent laptop but with booting time of about 3 minutes, "please wait" it is surely not impressing me given the fact that i have not installed anything yet...
2) I will try to uninstall applications like tempro but still I am puzzled by the slow reaction on internet pages.
For example when i go on google and start typing something most of the times the cursor freezes and i have to wait a few seconds before I am able to see what i am typing.
I have only bought it last Friday and I have not used much but surely a bit of a disappointment so far.
Any ideas why the cursor freezes on google or on the internet explorer toolbar?
for info i am using Vista Business OS and Internet explorer
any help welcome

Hello
About slow boot you can read very interesting and useful thread under http://forums.computers.toshiba-europe.com/forums/thread.jspa?messageID=134947
I hope this will help you to understand why this can happen.
After first start you can be faced with this behaviour. Few days updates will be downloaded and installed in the background and you will notice high HDD activity. These activities can slow down notebook performance and what you can notice is this slow typing reaction or freezing video play.
So my advice is to disable automatic updates and set it when updates are available you should get notification but you can start it manually. These all possible vista updates installation is for me big mistake because if you check available updates many of them are optional and some of them are driver updates (3 of them) these updates must not be installed.
Maybe you should install recovery image again. don't connect it to internet and do what is described in posted thread. After optimizing preinstalled OS change settings for Windows update and connect it to internet. Check list of available updates and install important and recommended stuff only.
I do always so and I am happy with my Satellite P200 and new A300. Both of them runs well and I am satisfied with performance.

Satellite Pro A300-1GT - Error message when starting webcam

I have a Toshiba Satellite Pro A300-1GT. The problem is that the camera does not work. When I start software it writes that I should restart camera or computer. I'm having Windows 7 and I serched the internet for solutions but I find just a discusions with the same problem without solutions.
Sory for may bad English.

Hi
The cam is not listed in device manager; neither as unknown device nor as USB device?
Well, I read here in the forum that internal webcam is connected to the USB controller on the motherboard and sometimes the connection is loose and therefore the cam cannot be recognized by system.
I think in such case the notebook needs to be disassembled and the connection should be checked. But this seems to be a job for technicians

Why does Satellite Pro A300 not start when the power button is pressed?

Suddenly my new Satellite Pro A300 will not start correctly when the power button is pressed. The situation is this: When I press the power button the Toshiba opening picture (Leading Innovation) appears and disappers quickly. Then there is a black screen for about 30 seconds. Then there is a rectangular frame with the text Microsoft Corporation underneath. And nothing happens however long I wait.
In order to get on with the starting proces I then shut down the computer by pressing down the power button until the computer stops. ("The hard way to shut down")
Now I press the power button shortly to turn on the computer. Then the computer starts normally with the Toshiba opening picture and after a few seconds I am asked to open the computer in safe mode or in normal mode. I now choose to open in normal mode and the computer opens normally and is ready to work.
What shall I do to get a normal start procedure?

When notebook starts normally (after choosing normal mode) shut down your notebook properly using START > Shut down option. Next start should be normal.
When the OS is switched down on irregular way you will be always asked how to start it again (safe or normal mode).
The same happen on my Satellite A300.

Satellite Pro A300 PSAGDE re-booting when plugged in

I have had this laptop put away for a while as I couldn't work through this problem, but I'm having another try.
The laptop is a Satellite Pro A300 PSAGDE.
The problem I am haiving is that the laptop would re-boot whenever I connect the PSU, but not when using a live CD (Ubuntu).
I would like to try and flash a replacement BIOS to see if that will solve the problem.
Unfortunately the software needed to flash the BIOS requires the laptop to be plugged in.
Is there any way around this problem?
Can I fool the software into thinking it is plugged in?
Is there a way I can revert/repair the BIOS in any other way as obviously the problem hasn't always been there.
Thanks

So once again: notebook runs fine using battery power but reboot always (in the loop????) when AC adaptor is connected. But using Live CD the notebook runs ok even if the AC adaptor is connected.
Right???
>> I think it may be a BIOS issue because the laptop will run without an issue when booting a live cd, even when it is plugged in.
If the unit runs ok using Live CD, then this means that this cannot be BIOS issue because BIOS does not depend on installed system.
Therefore in my opinion its definitely not a BIOS problem.
I think you should firstly disable the automatic reboot when an system crashes Win 7 is configured to restart immediately when a BSOD happens and this happens too fast to see the error I think you mean this by automatic reboot
Disable this by following way:
1)Control Panel -> System & Security -> System -> click the Advanced system settings
2)Locate the Startup and Recovery section near the bottom of the window and click Settings button.
3)In the Startup and Recovery window, uncheck the check box next to Automatically restart.
4)Now click OK and restart the unit
In my opinion the system crashed and therefore the notebook reboots
