Satellite Pro A300-28V - My bluescreens disappeared when BIOS was upgraded

I am curious about this. The machine is an Satellite Pro A300-28V with Vista32/Win7.
Had problems with bluescreen dumps referring to "iaStor.sys". I was just about to send the laptop in for repair when I made this last effort to solve the problem. Upgraded BIOS from 1.9 to 2.1-Win.
Suddenly my system image succeeded!! Even to an Iomega home network HDD. No hang-ups!
No bluescreen dumps even at "cold" start-up (after a night off)!
At the moment I let the computer home in sleeping mode while I am at work. Let's see if it managed a day without dumps.
What is the technical difference between BIOS 1.9 and 2.1? Any idea if it has anything with iaStor.sys to do?

Hi mate
This is really good news that your BSOD displeasured after BIOS update.
The BIOS give instructions to power-on self test (POST) and provide basic information about how to handle some notebook components, like HDD, ODD, memory which are needed to load the operating system.
Who knows, what has been changed in the update but the main thing is that everything work and the update solve your BSOD
>Any idea if it has anything with iaStor.sys to do?
iaStor.sys is a part of the SATA driver which is need for recognizing the HDD using the AHCI mode.

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 A300-1GT - 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

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

Satellite Pro A300 - Cursor constantly moves when external mouse connected

Hi there
I have a Satellite Pro A300. When I attach a mouse directly by USB the cursor is constantly moving. I also have a mouse attached via a Toshiba docking station and that works perfectly.
It doesn't matter which USB port I use or whether the laptop is connected to the docking station or not, or whether it is running on mains or battery power.
I thought it was the mouse that was the problem so I went and bought a new one but the problem is persisting.
Actually, while I have been writing this post, it has stopped doing it and then started again! Very frustrating.
Can anyone help?
Thanks
Susib

Hi
How about the touchpad does the cursor moves and jumps using the touchpad?
Try to disable the touchpad while using the USB mouse check if you can notice a difference
How about BIOS?
Do you have the latest version installed?
Check this!

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 - I get the "Windows search" if I left click any folder

I have just purchased a Satellite Pro A300 and downgraded it to Windows XP SP3.
When I left-click any folder icon on my hard drive I get the 'Windows Search' window displayed instead of opening the folder. When I right-click any folder icon, the first item in the menu (bolded) is 'Search'.
How can I change the order of these menu items so as 'Open' is the first item?
Can I remove (Control Panel-Add or Remove Programs) the Windows Search facility without affecting any software I have loaded?
Is having the Windows Search facility installed the likely cause of my problem?
Thanks,
Murray

Have just solved my own problem:
1. The order of items in the shortcut menu for Folders can be changed by updating the actions for specified file types in the Folder Options Menu. Select +Folder Options+ from the +Tools+ menu of any folder, select +File Types+ and scroll down to *Folder*. Click *Advanced* then click *New* and add *Open* with *Explorer* as the program to use. Click *OK* and *Close* and bingo! Appears the order of the short-cut menu in XP is Open before search, but in XP Pro is Search followed by Open/Explore.
2. The Windows Search utility can be safely removed despite the warning issued - the Microsoft website indicates the warning is simply a generic warning and it is highly unlikely that removal will affect any software installed since the Search utility was loaded.
3. The Windows Search utility was NOT the cause of this problem.
Trust this might save others the hours of research I had to do to find this solution ...

Satellite Pro A300 - shutdown issue

I have a brand new Satellite Pro A300-15V, which I have downgraded from Vista Business to XP Professional, using the original recovery disc.
Now I have problem shutting down the computer. When I click "Turn Off" it just shuts down and then restarts after a minute or two. Also, I can't bring it back from hibernation unless I shut it down on the button first.
Can anyone help, pls?

Hi guys
Im not 100% sure if my advice could help you but what you should do is firstly BIOS update to the latest version. Ive noticed that new BIOS were released last week for some A300 notebooks series.
After the BIOS update disable the WakeUp on LAN settings in the BIOS.
You could also disable the options like: "Wakeup on keyboard" and "Critical battery WakeUp"
*@cfrigerio:*
It seems youve already disabled this function but please check also the LAN card setting in the device manager -> LAn card properties -> Advanced tab.
There should be an option likes Wakeup on link, Wakeup using APM mode, etc
Disable these options!
Furthermore please check if any 3rd party applications dont wakeup the notebook.
Sometimes the scheduled tasks could be responsible for the irregular waking ups.
Good luck

Satellite Pro A300 PSAGDA: Problems installing webcam on Win 7

Hi there guys,
its been a few weeks since installing Windows 7, only for the last few days have i actually bothered to install toshiba software (dont stone me!).
Right now I've been scratching my head when installing the webcam drivers. When the install is done and after a reset, all it says is Webcam failed to initialize, please restart cam or computer.
Restarting the laptop wont do anything
I am using a Toshiba Satellite pro A300 PSAGDA-01C00R, do these drivers simply not work for the time being on 7?
any help would be great, thanks!

Hello
I have installed THIS version of webcam driver on my Win7 preinstalled Satellite A300 and it works perfectly.
I have tested preinstalled software and it runs well. I have also tested it with Skype. No problems at all.
Test it on your Satellite too.

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]

Satellite Pro A300 standby and hibernate functions not working properly

I have a new satellite Pro A300 PSAJ1E - 01E00VIT, and I'm finding this problem:
Sometimes, (not always: may be it depends on which program is running) when trying to put the computer in stand-by or in hibernate mode, it doesn't stop, but only shuts down the monitor (panel), while the fan goes on running and the power light is green. Obviously, lots of battery energy consumption!
Then there is no other way of resuming than shutting down the computer by holding down the power button long time... but this is not correct!
NB: my computer is always connected to a lan, and generally there are some browser windows open when I put it in stand-by mode.
How can I fix this?
jomurray

Generally you are right but the point is that you have said that this issue doesnt happen always but sometimes.
> Sometimes, (not always: may be it depends on which program is running) when trying to put the computer in stand-by or in hibernate mode, it doesn't stop
Fact is that some single applications which are running can prevent the execution of standby mode or hibernation mode.
Therefore if you are running such programs you will have to close it firstly.
I dont say that this must be done with all applications. ;)

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)

Re: Satellite Pro A300 - shutdown commands mixup

*Satellite Pro A300-15T Model Serial No. 58256558W, Part No. PSAJ1E-00F00YAR*
1.It has been observed that when shutdown command is given, sometimes the laptop goes to restart mode and logon screen appears after restart.
2. When the sleep mode command is given, sometimes it does not go to sleep mode but rather goes to logoff mode and logon screen appears.
Why the laptop is not properly executing the commands related to sleep, shutdown and restart.
I have not changed any settings of the power buttons.

Hello
Has your notebook factory settings or you have installed own operating system?
How you give these commands especially command for sleep mode?
In front of me I have Satellite Pro A300 with original preinstalled Vista. Everything works well.
Using FN+F3 notebook switch in sleep mode.
Using FN+F4 notebook switch into hibernation mode.
I have tested options for power button and closing lid too. No problems at all.

Satellite Pro A300 PSAJ1E doesn't wake up from standby correctly

I have a new Toshiba Satellite Pro A300/ PSAJ1E - 018006EN with similar problems too.
When mine goes into sleep mode it will not re-start unless the power button is pressed 'numerous' times, eventually it powers up, but in safe mode and everything that was being worked on is lost.

I too have a new satellite Pro A300 PSAJ1E - 01E00VIT, and I'm finding a similar problem.
Sometimes, (not always: may be it depends on which program is running) when trying to put the computer in stand-by or in hibernate mode, it doesn't stop, but only suts down the monitor (panel), while the fan goes on running and the power light is green.
Then there is no other way of resuming than shutting down the computer by holding down the power button long time... but this is not correct!
NB: my computer is always connected to a lan, and generally there are some browser windows open when I put it in stand-by mode.
