Satellite Pro U300 PSU31E - two how to adjust the fan speed

While using the laptop the fan comes in for a few seconds and then stops again, which causes the temperature
increase... what makes the fan?
Throttle upward rather than stay in a slow to medium status.

I'm running Vista Business, but I did ' t find the parameters in this regard.

In the ACPI BIOS is not accessible, but as already posted my problem looks a bit like this:

Re: ACPI fan on Satellite L30

The fan goes in cycles like this:
------------------
Less than 50, fan
When > 55, fan to full
When< 55,="" fan="" on="">
When< 50,="" fan="" off="">
and it continues

------------------

It would be much better than when he went to more than 50 years she just spend on bass, then
It would never reach 55 and never go up.
And the laptop would be 100 x more silent.

Another thing: the Germany from Toshiba support page won't load at all or is the global page
very slow, using different locations and conections. That I can not retrieve all the information to help me.
And I do not think the University backbone or my DSL 6 Mbps at home is the problem

Hello

The fans begin to turn only if a certain temperature point has been reached.
These fan table information is stored in the BIOS and cannot be changed.

Some computers laptops satellite supports an additional option in the Toshiba HWSetup. It allows to change the CPU dynamically switchable or always low frequency mode.
This would set the temperature to a lower level and the fans would lead occasionally.

In any case, to my knowledge, this option is not available in the Toshiba HWSetup and not in the BIOS so I guess that it s not possible to control fan behavior.

By the way; If you wish, you can test a tool like aSpeedFanfreeware.
This program can control the speed of the fans according to the temperatures of the system.
Maybe it will work on your Satellite Pro U300

Good bye

  • Satellite Pro U300 (PSU31E) standby & hibernation fails after updating BIOS

    Hello

    I wonder if it is common that after the upgrade of the Satellite Pro U300 (PSU31E) of the BIOS 2.50 at BIOS 3, 70 - Win or 3, 90 - Win, do sleep modes and Hibernate the * completely locked laptop computer? *

    After the upgrade, when I try to enter sleep or hibernation, the laptop turns off the LCD and gets locked so it isn't help to press and hold the power button, open/close the cover, press Fn - F3 or F4 - Fn, the only way is to disconnect the power supply and wait until the battery runs down, or simply be very rough and * disconnect the battery *.

    While the Pro U300 is locked, I hear that HARD drive and fans are also swivel - as soon they were when entering standby or hibernation mode. Very ugly behavior - you can FRY your laptop with something like that. I thought that BIOS 3.70 was faulty but unfortunatelly version 3.90 also worthless.

    Furthermore, I can't yet understand why large (70% of the zip file) file of the package to upgrade the BIOS (3.70 and 3.90)... is the portable other flashers log file?

    Your ad, I understand that the screen does not wake up after its entry in the standby or hibernation mode.
    Am I wrong?

    I noticed that Toshiba has released a new version of the Intel graphics driver.
    At this time the update is 02/20/08 and the version is 6.14.10.4831.

    Maybe you should try to update the display driver too check to see if it would help to get rid of this annoying display problem

    I recommend to remove the old version of the graphics driver first, then install the new downloaded driver.

    Mate good luck

  • Satellite Pro U300 (PSU31E) - freezes on the Welcome screen

    Hi all

    I have a Toshiba Satellite Pro U300 model no notebook 01900REN PSU31E purchased as new and connected to Windows XP.

    It worked perfectly fine for about a year until very recently when it started freezing on blue welcome screen. I had to disconnect the battery because it has not proceeded past the blue welcome screen. I ran the antivirus avast but it nothing of the detected note. Now even when I disconnect and reconnect the battery the screen does not go beyond the Welcome screen blue even if the mouse is moved again, and occasionally the pointer arrow-pointer to sand-clock pointer initially and then rest as arrow-pointer changes. Pressing buttons, Ctrl + Alt + Delete, using the mouse or the battery are not any good.

    I backed up things but not until recently. Please help me, I'm an amateur like these sorts of things, I'm English teacher from teaching professional so I really need materials and capabilities of the laptop. What should I do, please help!

    Thanking you in advance,

    Hey the view,.

    Have you tried the same thing in safe mode? Go to the advanced boot menu by pressing F8, select Safe mode.
    Check it!

    It of really difficult to say why this is happening but if it doesn t work I think that it s time to reinstall Windows. So take the Toshiba Recovery disk and boot from it. If you follow the instructions on the screen you get factory in minutes! :)

    Hello

    > Is it possible to adjust the speed of the fan of this laptop? As I saw in PC Health monitor the fan speed is mainly of 0%, and sometimes it amounts to 70% (on idling) and make a big enough noise

    I agree with you, I also own a500-1dn and it makes big noise even while surfing Internet. This forum was suggested to update Bios to reduce the fan noise.

  • Satellite Pro M50 with Vista: how to get the S-video on the job?

    Hi all

    I have a vista equipped Satellite Pro M50. Does anyone know how to get the S-video on the job? I can't understand.

    Inadvance, see you soon

    Phil

    Did you look in the user manual?
    This doc is always pre-installed on laptop and provides useful information. Also how to connect a TV and use simple notebooks ports.

    A hint; You must use an s-video cable to connect the laptop to the TV.
    Then use the FN + F5 key combination to switch between display devices.
    Sometimes the special s-video option must be enabled on the TV.

    I would recommend consulting the manual of the TV also.

  • Satellite Pro C660-29W. How to remove the supervisor password

    Hi all
    I've been locked out of my bios and I don't know the password. My little brother was playing with my laptop computer and accidentally set the supervisor password. Is it possible that I can recover the password or reset it? I really need to change my boot sequence as I just bought a new SSD and need to format my laptop. Suggestions will be highly appreciated.

    Here's my version of bios and details of laptop

    Toshiba satellite Pro C660-29W

    CPU Intel Core i5 2410 M

    8 GB Ram DDR3

    BIOS: BIOS FRIEND - installation utility Aptio
    BIOS system ver: 1.50
    THIS Version: 1.50

    Thank you

    Supervisor password is very important safety device and a kind of reset of the user is not possible. You can cancel it, but you must know the correct password to confirm that you are the real owner computer laptop.

    Toshiba provider in your country can help you with this. You just approve that you are owner of the laptop, and they can cancel it for you. Of course, you must pay for it.

    As far as I know, there are several techniques for the removal of password and it depends on phone model.

    Contact the closest Toshiba ASP and ask for help.

  • Satellite Pro P300 - 13 M - how to replace the network card?

    Hello I have the Satellite Pro P300 - 13M.

    My sister fell on my UTP cable and so he was taken out by force and because of that "holding-pings" on the front of the port are bent or broken, so whenever I put in a cable with traction slightess or accidental poke I'm new offline...

    I'm out of my warranty period, is it possible to fix this? Can I replace it myself?
    USB network adapters are a viable solution to replace if I can't replace it?

    Help > _

    To resolve this issue, you must replace the motherboard. The network card or a network location is soldered on the motherboard and cannot be traded.

    In addition, it would be not covered by warranty. This isn't a matter of Toshiba, this is caused by the customer.

    However, if you want to repair you must contact an ASP or search you on eBay for a card mother of second hand.

  • Re: Satellite Pro L450D - 12 X - how to access the recovery partition?

    Hello

    I've formatted Windows 7 with a Windows XP CD but did not setup. I wanted to know how to access the recovery partition to set it by default, everything exists on the laptop right now is Ubuntu, but I don't know, I saw an additional partition that must contain recovery files as laptop did not come with a recovery disk and unfortunately did not create a filter.

    How can I access the recovery partition on the laptop having in mind, I formatted the drive Windows 7 was installed on or should I activate or something like that?

    Any help much appreciated

    Hey,.

    On the second partition of your laptop (data partition), you will find a folder named HDDrecovery and it contains recovery files. The problem is that you can use the HARD drive only with the pre-installed operating system recovery feature. It would mean in your case it s too late now and it s not in use anymore.

    You have created the Toshiba recovery disc as mentioned in the user manual? If Yes, you can use this disk to restore to factory settings. Just boot from this CD and follow the instructions on the screen.

    If you don t have the recovery disc, you can order it here:

  • Satellite Pro S500 - 11 c is suspended and the fan runs at full

    Hi people,

    I am experiancing a problem with my Satellite Pro S500 - 11 c where close unexpectedly, it crashes and the fan runs at full speed. Discount to zero is my only option and this resulted in the windows having to retrieve a few times so I'm fearing one requiring a major reconstruction after a deadlock of the future. Until now this issue has occurred only when you use a wireless USB mobile of 3G or internet teathering via USB with my iphone 3G. Using another USB port did not help.

    If someone has encountered this problem and have a fix? No help from Toshiba?

    Best regards

    Andrew

    Hmmmm... What to say. Problem is that you use third party hardware and software and some conflicts are possible. The question is: who can help you with this?
    In general you should talk to your ISP provider at first to see what they will say about all this.

    Have you ever talked with them?

    > I mean with power of change in BIOS, I don't have the option advanced on my BIOS so I can't change that... Any ideas?

    You cannot change fan speed yourself, because there is no option in the Bios. I also tried to change with utilities like a fan speed control utility. But I couldn't stand it. Perhaps, someday they will out of the Bios with support for fan speed control. :)

  • Satellite Pro C660 - 21 d - how to change the shared memory graphic value?

    My dxdiag screen says I have almost 1700 MB of video memory, but when I try to use this memory on games these games can use 256 MB...

    I tried to change settings in the BIOS, but it does not have this setting, do not know what else could cause this problem?

    Hello

    This could be confusing, but this isn't a problem.
    Shared memory is controlled by the graphics driver and the driver affects the part of the main memory to the memory of the graphics card ONLY if its required by a running application.

    The Dxdiag shows you how much RAM could be shared and value of memory in the quizzes you shared memory which is used and who is in the game right now.

    I understand that there is a brightness of toshiba laptop display utility.
    Can someone tell me if there is one for XP and if possible to direct me to it

    Hello

    Usually, the FN + F6 and FN + F7 key combination decreases or increases the brightness of the display.
    But this only works if the Toshiba drivers are pre-installed. So check first if you have installed all the drivers needed and utilities on your laptop.

    Do you know where to find the necessary drivers on the Toshiba page?
