External USB hub limit for Satellite Pro C650

Is there a limit to how much you can connect via the Satellite Pro C650 of external usb ports?

Provides four ports hub I, ports seem to work individually and all devices operate normally when plugged directly into the top of the Tower, but when all devices are plugged into the hub and combined high tower, there are future errors.

Thank you
Karyn

Well, I think that this should not be a problem if the unique USB hubs provide clean power.
The fact is that the only USB port provides common 500mA and if several devices would share the power of a USB port then it might be possible that the 500mA available would not be sufficient for all USB devices.

  • External USB floppy drive for Satellite Pro M70

    I just bought a Satellite Pro M70 Centrino Mobile 750 to replace my Satellite 5105 - S702, which exposes the same type of problems of corruption/crash video display described elsewhere in these forums.

    I need an external floppy drive, and the site of the Toshiba shop specifies an external USB Floppy Drive Ref. PA3109E-3FDD.

    However, I have an external drive USB Floppy, Réf. PA3109U-1FDD, I bought for the satellite 5105-S702 about 4 years ago.

    5105-S702 has USB 1.1 ports and satellite Pro M70 has USB2 ports.

    Issues related to the:

    PA3109U-1FDD will work with the satellite Pro M70?

    There are likely to be problems of compatibility, driver issues or any probability/possibility of damage to the Sat ProM70?

    Would appreciate any advice.

    Thank you

    Hi Alan

    I really don? t know why you ask if the floppy drive will not work. Why you don? t he try? As far as I know, it should work and you should not buy a new one.

    Just for info: a few months ago, I saw the Toshiba FDD drives with part number PX? And these drives are not bootable but on the lower side, there is a label with this information.

    Anyway, you can use your other more ancient. According to the specification tested for MS M70 is FDD Drive Kit PA3109U-1FDD (your one).

    Good luck

  • Windows 8 Pro upgrade possible for Satellite Pro C650?

    Read in forums, but can't see a particular mention of my model of laptop. Short part PSC13A.

    Just bought Windows 8 Pro with the intention of upgrading to Windows 7.
    Anyone with this model manages to do with success?
    Should I first download an update to the driver? Or install Win8 first and then update driver?

    Have run the upgrade wizard and seems mostly ok apart from "your PC firmware does not support secure boot if you won't be able to use it in Windows 8.".

    That's what worry?

    Thanks for any help that you can give a geek MOM. =-)

    Secure boot is a new feature of UEFI firmware. UEFI replace BIOS on laptop computers that are provided with Windows 8...

    Windows 8 will work on PCs that have a BIOS, you do not need UEFI / Secure Boot.

  • Satellite Pro C650 - USB ports now DEAD

    Over the past 48 hours have really struggled to get my USB ports work,
    Toshiba SATELLITE PRO C650 lappy running W7... At only 2 usb ports.

    A couple of days, I bought a new stick of memory... 16 GB SanDisk Cruzer Blade... He stuck in lappy and anything that happened outside my mouse attached wireless stopped working.
    Since then, the ports were completely dead. (stick now appears on anotherPC)
    That's what I did so far, after a search web solutions thro...

    Device Manager display ports everything is OK with no exclamations...
    When I insert any USB device... no sound confirmation of PC and Dev Mgr flinch...
    Tried to uninstall port/hubs and leaving W7 re-install them using... Still dead...
    Trying to remove battery and power sector during the centuries, then re start off the power... Still dead...

    I think that my last resort looking for a factory system by default re install... but one have a mountain of things astro which must be saved and cannot be done through many many discs.
    I really want to be sure ive tried everything before you do this.

    Could I have really damaged the MB. ??
    I now nowhere so fast if theres anyone out there has any suggestions please shout...

    > I think that my last resort looking for a factory system by default re install... but one have a mountain of things astro which must be saved and cannot be done through many many discs

    Even if it s really painful to get everything installed it again, I would recommend to recover the laptop using the Toshiba recovery disc or HARD drive recovery.

    > Could I have really damaged the MB. ??
    Well, it's hard to say before trying the recovery procedure.
    If the USB ports are not working after using the recovery disk (or HDD recovery), then of course: the mobo may be affected, therefore, in my view, the laptop must be set to the factory settings.

  • Satellite Pro C650: USB flash memory starts to load then crashes

    Hello

    I have my new Satellite Pro C650 laptop for about 2 weeks and there is already a problem with it.
    When I insert a flash drive into a usb drive, it starts to load, but as soon as it loads it crashes as if I disconnected, and then start loading again again and again until I have unplug it really.

    The flash disk works fine on other computers, so it shouldn't be the problem.
    Device Manager indicates that my drivers are ok.
    Is not only the USB flash drive mouse works fine when I plug in usb...

    Does anyone have an idea how to solve this problem?
    If so, thanks in advance

    Hello

    Strange in your case I recommend you test another USB key into the Satellite laptop. I know you have tested this stick in other laptops, but it would be interesting to know how the other USB key would be instrumented C650.

    I recommend in addition updated the operating system Windows and the BIOS to the latest status.
    In addition, you should go to Device Manager and delete the list of devices USB controllers. Then restart the device and wait for windows has installed again all the USB controllers.

    Hi Jim

    I recommend you to reinstall the OS and test the feature with the factory settings. Please, test it with several different USB devices. If none of them works, you must contact the Toshiba service provider in your country and leave check s portable.

  • Satellite M300: speech recognition only works with external usb hub

    Hi all

    I have the Satellite M300 I could run the speech recognition program before you have the motherboard replaced due to failure of the usb.

    I found using the headset, I can not reach high enough quality to operate it.
    The only way I can use the Word program, use an external usb hub with its own power supply.

    The problem concerns the audio card, or simply not enough voltage?
    And na fix?

    See you soon

    Hello

    The notebooks of USB ports provide a standard power of 500 my.
    As I said that it is a standard, but in USB devices different part 3 external cases need more power.

    For example, one of my external USB 2.5 HDD s must be connected with two USB ports at the same time to ensure that the HARD disk would get enough power to function properly.

    Your external card is unknown to me but maybe it needs more power as usual.

  • Satellite Pro C650 - arrow, slash and z keys do not work

    Can anyone help - my slash keys, arrow keys, z and question marks have stopped working.
    I saw several other posts on different forums for exactly the same combination of keys.

    I have a Satellite Pro C650.

    Looks like a malfunction of the keyboard.
    You can use the external USB keyboard properly?
    If you haven't noticed the same problems with the external keyboard, then I would recommend replacement of the internal keyboard.

  • Satellite Pro C650 - does not start

    Hey all,.

    My Satellite Pro C650 boot not beyond a certain point. I tried to start in all modes different for example safe mode, mode of networking,

    However this proved unsuccessful, the laptop freezes and I meet a constant and regular beep at the same point every time that I try to start. I even tried to start Linux 12.04 USB to see if it's hardware or software, unfortunately is the same, which means hardware failure.

    The problem is that I don't know the bios beep codes and I can't understand what needs fixing.
    I was hoping you could help me!

    Thanks :)

    I think you need professional help with this problem. I don't know if your laptop is always guaranteed to be valid, but in my opinion, you should contact the nearest Toshiba authorized service provider and ask for help. They have special diagnostic tools and hardware malfunction can be detected and repaired.

  • Dynadock U10 goes into sleep to help with Satellite Pro C650-139

    We have several Toshiba in my work, we have 2 Toshiba Satellite Pro C650-139 with Toshiba Dynadock U10 (PA3575E-1PRP), and these moorings seem to go to sleep every now and then, sometimes, the screen freezes on the screen connected to the U10. Is there a solution? or just pass these stars?

    Hello

    Have you noticed that using the Dynadock as part of another computer/laptop?
    I asked this because it might be possible that your affected laptop connection settings between the laptop and Dynadock.

    To my knowledge, you can set the Dynadock standby mode but in this case the Dynadock would unplug the computer.
    In Dynadock options (in the task bar, click the Dynadock icon), you can find the Eject option and sleep. This disconnects the Dynadock and set it in standby mode.

    I think you should check the Dynadock with different USB ports.
    Deactivate the energy saving for the USB ports in your Win 7 power management settings.

    In addition, you can update the graphic driver for Dyandock.
    As far as I know, you can find the latest version of the driver here:

  • Satellite Pro C650, boots OK, after Windows starts to the top of the screen becomes white

    Hello

    I have a Satellite Pro C650.
    It starts very well.
    I see Windows commissioning - after start-up - the screen goes completely white.

    Has anyone seen this?

    Am geussing there could be a loose view link - but I have the screen displays the start-up and initial windows startup sequence.

    Kind regards
    eeiddne

    Hello

    I put t think that your display is faulty.
    What happens if you access the BIOS at the beginning?
    To access the BIOS F2 press and turn the device on/off.

    Access the BIOS and let it run for a few minutes and check if the display starts at White.

    In addition its recommended to connect an external monitor and generate the display 2. If the 2nd screen is not OK, then the graphics chip could be the troublemaker.
