Cooling behavior after BIOS Flash - Satellite Pro A300

Hello everybody,
I have two laptops, Satellite Pro A300 and Satellite A300. Both have the same configuration, C2D E8300,2GB,ATI 3650 512MB and so on.....
Today I flashed BIOS to the latest version (from V3.90 to V4.20) on both of them. On the version 3.90 cooling was OK, fan worked only when it was necessary. But now after flashing the BIOS fan works permanently, it does not stop.
What I did make, in Vista's Power Options under Toshiba Power Saver I changed the Cooling Method from Maximum Performance to Battery Optimized, the cooling reversed to the normal operation, but the cover (keyboard area) became hot a little bit.
My question is, what is the problem with cooling in the new version (v4.20)? And how to solve this problem?
Again, problem didn't exist before BIOS flashing and the problem is on both computers.
Thank you for your help!
Best regards,
Osman

Hi mate
Thanks for the feedback
> So what do you recommend me, to stay on Battery Optimized mode? Generally speaking, what's the difference between Maximum Performance and Battery Optimized modes in Power Saver?
Usually its advisable to use the Battery Optimized mode only when the AC adaptor is not connected to the notebook and the notebook uses only the battery power.
In such case the notebook does not waste the power using Battery Optimized mode and you could use the notebook much longer using battery only.
Using Battery Optimized mode the CPU and cooling modules run with lowest performance and the CPU does not create high heat dissipation.
This leads to a lower internal temperature and lower usage of cooling modules.
Bye

  • After v1.90 BIOS update Satellite Pro A300-1EA wont boot up

    I have just upgraded my laptop to the new BIOS as stated in the title but after doing it my computer now wont boot up at all. I just get a blue screen with it asking me to do a CHKDSK because there might be a virus or that the hard drive isn't connected properly (when it is), and it just keeps rebooting.
    It wont start in safe mode either. Anyone else had the same problem and if so, how do I get my laptop back?? :(
    Thanks for any replies.

    Please don't be mad on me but I think you really didn't read users manuals you got with your notebook. There is exactly described how you can have factory settings again.
    So, now you are 100% sure that recovery image is not on the HDD but you don't know how to have factory settings again. Strange.
    Remove battery, connect AC adapter only and disconnect all attached external devices.
    Start your notebook and enter BIOS settings. Set it to default settings and try to start OS again.
    What happen exactly?

  • Satellite Pro A300-1DZ does not find HDD after BIOS update

    Hi everyone,
    I have recently purchased a secondhand Satellite Pro A300 1DZ.
    Put a fresh copy of Windows xp home on it.
    I then went on to install all the drivers needed from Toshiba's own site and at the end of this I thought it may be a good idea to update the bios????
    OH DEAR what a big mistake.
    Now the netbook will NOT start windows.
    So I thought thats ok I will just start from the begginning and reinstall windows again, but it is telling me it cannot find a hard disk on my netbook?
    aaaaaaaaaaaaaaahhhhhhhhhhhhhhh I am going crazy,
    Could someone please tell me how to fix this? Thank you x

    Hi
    I think the option SATA mode has been set to AHCI and therefore the Windows XP cannot find the HDD.
    This is because of the SATA controller.
    You can set the SATA mode from AHCI mode to compatible mode and this will allows you to install the Win XP on the notebook without the usage of SATA drivers.
    So, youve got two options if you want to install Win XP:
    AHCI mode -> but you have to include SATA drivers
    Compatible mode -> Win XP installation possible without the SATA drivers

  • Re: Satellite Pro A300-1EA - Difficulties in BIOS update

    Hi there,
    I attempted to update BIOS on my new Satellite Pro A300-1EA (PSAG9E-001001EN) as prompted by Tempro, from version 1.50 to 1.90. The system froze completely during BIOS flash, after waiting for 1 hr, I decided to turn off the power and pray for the best. Thank heavens, everything still works, but the BIOS is still v1.50, not been updated. I have now read so many posts on the forum regarding blotched BIOS update and am now very cautious regarding undergoing any BIOS updates at all.
    My questions are: Are there any issues regarding this particular update and/or with the InsydeFlash facility? Are BIOS updates all generally so tricky that they best be avoided? What are the alternative ways to update BIOS, hopefully less dangerous? Also, could there be any potential damage to my laptop related to this miscarried BIOS flash that I should be aware of?
    Many thanks indeed!
    Monsteress

    You can feel you lucky, buddy! :)
    Im surprised that your ROM module is not damaged or something else. In most cases this happens if the computer freezes during the update.
    Let me give you a word of advice. You should only update the BIOS if its necessary or you have problems/issues with the notebook. You can ignore the messages from TEMPRO if your system runs properly. For example I never update the BIOS if my notebook runs perfect Never touch a running system ;)
    Otherwise follow the tips posted by Akuma Before you update the BIOS close all running programs, disable AntiVirus and Firewall and connect the AC/DC adaptor.
    On my Satellite U400 I have updated the BIOS without problems.

  • 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 A300-28V - 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 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:

  • 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 - 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 - 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 ;)

  • 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: cam picture appears which has been taken 6 months ago

    Hello everybody,
    I have a problem with my Camera Assistant Software. I'm using a Toshiba Satellite Pro A300.
    I used once my camera for taking pictures and now after 6 moths I wanted to take a picture again, but it appears the last picture taken 6 months ago. I uninstalled and than reinstalled the software and the same problem occurs. I tried to change some of the settings and this didn't help too.
    I would be very thankful, if someone could help me!!!

    Hey Dr. Lamp,
    I think this could be the same problem, but I can't find this "screen cover" in the settings and effects of my camera.
    All the other suggestions I have tried (removing the picture, reinstall and so on).
    Maybe you can help me to find this function for my Camera Assistant Software version 1.7.
    Thank you!

  • 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 A300-1H2 - Windows does not recognise HDD

    Hi,
    i'm a newbie, this has probably bin asked before so if it has you'l have to excuse me, i have a satellite pro A300-1h2.
    I got the blue screen unmountable boot volume, so have tried to fit a new samsung drive. I put in my windows disc it loads all the drivers then says there is no hard disc?
    In bios it recognises it ???
    Thanks if anyone can help

    Hi
    The problem is that your notebook supports the HDD SATA controller but the OS system does not contain the SATA drivers
    You could set in BIOS the SATA mode to compatible.
    This will allows you to install the OS without the installation of SATA drivers.
