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?

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 A120 cannot boot up when printer is connected

Hi I have a brand new Toshiba Satellite Pro A120 but am having a very strange problem.
I installed my printer - Epson Stylus Photo R300 but now the laptop wont boot up if the printer is turned on. When I turn it on the Toshiba screen comes up ok, then the Windows XP screen comes up with the black background when the blue bar goes across to load Windows but its all faded out and the laptop just freezes and will not power up!
However if you turn the printer off and re-start the laptop it boots up fine!
Its definitely the printer that is causing this as its only when I have it turned on.
It never caused this problem with my old PC that was using Windows XP too.
Any help with a resolution would be greatly appreicated.
Thanks
Adam.

Hello Adam
I am afraid there is not much to do. Friend of mine has the same problem and the fact is that Epson chipset is pretty bad and it gives completely wrong information to the system. Because of that notebook is confused and can not start.
I can just recommend you to use USB hub and I hope it will work. I dont know if your notebook can boot from USB device but if this option is available please disable it.
Good luck!

How to disable UltrNav when external mouse connected

Is there a way to have the UltraNav turned off automatically when an external mouse is connected?
When typing it’s too easy to inadvertently touch the UltrNav and if you’re not watching find you’re typing in a different location, so we like to turn it off. But when I need to quickly access the laptop I would like to use the UltrNav and not have to find and connect the mouse.
I can turn it off/on through the control panel/system tray, however it’s near impossible to turn on without a mouse.
Our users have gotten use to this feature in other laptop brands but according to the Lenovo help desk it’s not available.

Hi, GDodman
Unfortunately, I don't think this option is currently supported on Lenovo Think brands. I did some research on the topic and attempted to change the settings of UltraNav, but was not able to find this function. If you find that UltraNav is too easy to inadvertantly tap while typing, then I would recommend changing the sensitvity to a lower setting to reduce future misclicks and random movements.
Best of luck,
Adam

Can't disable touchpad when external mouse connected

Hey guys,
OS: Win7 64Bit
Product : b0p18pa#ab4
Model: dv6-7007tx
The only way i've figured out a way to disable the touchpad is to uninstall the PS/2 compatible mouse in device manager. (which requires a restart) to come into effect and is reinstalled after the next restart afterwards.
the touchpad is SO sensitive it makes it extremely aggrivating to type as i keep tapping the pad with my palms.
any insight would be fantastic.
cheers guys.

Hi,
Please try:
   Control panel > Mouse > ClickPad Settings
   Tick Disable internal pointing device when .....
   Click Apply
Regards.

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 A300-28V - 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.

Satellite Pro A300 can not find USB devices

Hello forum,
we have a costumer who has bought a Toshiba Satelite Pro A300 from us, but he gets a strange error on it.
he connects a Sandberg USB 2.0 5port Hub to one of the usb ports, the pc finds the hub, but when he connects a memory stick to the hub nothing happens.
the hub and memory stick works on others pc's.
hope somebody can help.
best regards
John Bork
DANBIT A/S

Hi
What happens if you connect the memory stick directly without this USB hub?
I had also an USB hub but these hubs are a little bit complicated and tricky The USB specifications allows a certain power and depending on the devices that you connect you have to use an active USB hub, that means with external power supply.
But normally Satellite Pro A300 should have enough USB ports If its necessary I would recommend an USB hub with 2 or 3 ports maximum

Satellite Pro A300-1E7 - cannot start cam software

I have purchased the Satellite Pro A300-1E7.
Webcam is not functioning properly in MSN messenger video call.
Am having similar problems to the previous posting except I am using Zonealarm.
I think Zonealarm challenged cec_main.exe in a similar way.
I have tried to follow the instructions on here but without much success.
I removed Camera Assistant SOftware and re-installed the driver but doesnt appear to have improved things.
Now c:\program files\ camera assistant software for Toshiba has disappeared altogether and the the camera assistant panel no longer appears on the side of the desktop.
Any ideas please?

Hi
I used the Zonealarm is the past and I was not really satisfied because this software locked everything and most applications didnt work properly even after new configuration! Finally I removed this software and I noticed further advantage; my notebook boots much faster!!
I think this software would lock the cam software too.
> Now c:\program files\ camera assistant software for Toshiba has disappeared altogether and the camera assistant panel no longer appears on the side of the desktop.
This would mean that the software was removed and was not installed properly.
But to be sure, check in control panel -> Software (add & remove programs) if the webcam software is installed.
Ive got the internal Chicony cam too and its working fine in connection with Skype software. I didnt test MSN but I dont see any serious reasons why it shouldnt work.
In my opinion you should firstly remove the zonealarm. Then clean the OS using CCleaner. Finally download the webcam software again and reinstall it!
The webcam toolbar is not always visible on desktop.
It would appear only if you move the mouse cursor to the place where the webcam toolbar was hidden.

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 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 ...
