Satellite M30X powers off the power when you touch the USB port

Hello everyone, just registered and it is the first problem:
As there is no general hardware forum, I post my problem here.

I got it twice, my laptop
(Product: Satellite M30X, Version: PSA72E - 008010GR) just went completely off.

Motherboard:

NorthBridge: Intel i855GME
SouthBridge: (ICH4-M) of 82801DBM LPC Interface Bridge
Motherboard model: Toshiba EAL20

USB:

82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI controller #1-3
Version: 1.0
Interface: UHCI
Frequency: 48 MHz

82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB 2.0 EHCI controller
Version: 2.0
Interface: EHCI

I have the latest Intel Chipset drivers installed and Windows XP Home SP3 with all updates.

Once when I hit just the back USB ports with a USB plug, the other time when I unplugged my bluetooth key (climbing din't remove it).
There was no blue screen or message of any kind, not even in the registry after you start the system again or this fatal system error box when you start after a system error.

Just a total failure. But it works fine the rest of the time. I also tried to remake the script, but it didn't work.
I have cleaned with a vacuum cleaner to remove dust and has taken a good look, but saw no difference to the side track.
Maybe the clamps of the wand to shield a little more out to the contact pins on the rear.

What bothers me a bit, it's some time ago, I had the laptop one computer my knees and I forgot that a memory stick has been connected to the rear. The stick was pushed up and was slightly damaged.
Still works well. Now for me, that I broke the USB port Insider somehing.
I could not determine also the loose parts or unfirm at all.

Y at - it there, diagnostic software that measures the motto of the port or power problems?
I have a multimeter, fetch short-circuits with it?

I saw a package of drivers Intel for USB 2.0 over there, but I can't find it on their page, advice?

Thank you very much for your help, I just wanted to update my RAM and now I am not so shure if my laptop will last the next week.

Hello

I put t know any diagnostic software that could analyze this question, I think that a technician of the ASP may be able to provide exactly this question results

> What bothers me a little is that some time ago, I had the laptop and my knees and I forgot that a memory stick has been connected to the rear. The stick was pushed up and was slightly damaged.

I think this might be the reason why the laptop stopped while you touch the USB port eventually ports were damaged by using the memory stick, this could cause the laptop off

However, what we can do is to provide some suggestions and assumptions
It you want to know why this is happening exactly, then you need to contact a technician laptop for a control.

  • Satellite 2435 powers off the power when you try to install the recovery CD of OS

    Happy new year

    Satellite 2435 powers off accidentally when trying to install the operating system from disk with Windows XP Pro startup disk or recovery.

    When starting and working with Winternals AdminPak 5.0, Portable Edition Windows or Dos 6.22 it works stable.
    When booting with the disk recovery he died each time in a different position - when partition formatting, copying the files, etc..

    Hardware problems, isn't? And is it possible to determine and solve the problem at home (because we now hoildays, services does not work)?

    Thank you in advance.

    (Sorry I don't speak English very well)

    When I had my old computer I encountered similar problems in Windows XP and the Windows XP installation. There is a WinXP option to disable the auto-restarting after a problem, instead of restarting, a blue screen stating that the problem appeared. I lived during the installation of WinXP blue screens every time at various times as you and your power off, he appeared on the different WinXP CD (without SP, SP2 with nlite, etc.).

    Maybe your "power off" is hidden blue screen too, but I'm not sure. If this is the case, it may be a hardware problem, so you should test your RAM, your drive hard, etc., for example using memtest for your RAM and the built-in WinXP 'chkdsk '.

    It's probably hardware problems. Were you ever able to correctly use the disk without problem in the past, or is this the first time you try to use the recovery disk?

  • WiFi radio adapter off, the USB ports does not and the Bluetooth adapter is no longer visible... Please help!

    I had my laptop Dell Vostro repaired under insurance in January 2013 after a spill of liquid.  HAAC Ltd. has replaced most of the laptop - but the return, the SD card did not work.  This seems to be due to the engineer he connects not properly and the company recommended it and returned it to me again.  A couple of months, I found my USB was temperamental - so is my built in Bluetooth adapter.   Last month - the wifi does not work for most of the time either so I have to connect to my router by wire.

    This could be a problem in windows 7 - all my problems seem to be related to network adapters.  If it's a hardware problem - does anyone know if it could be another loose connection?  HAAC Ltd. only give a 3 month warranty on parts that seems just a little.  But if this anomaly is due to the production of poor quality - that is not properly connect the laptop then I'll go back their again if they are responsible.

    By the way – there's a switch wifi on the front of the laptop - but is not currently be recognized.

    If anyone has settings that I could check that can help - especially if some inhibit the use of wifi.

    Thank you very much

    Hello

    Your wifi switch not recognized is probably a hardware problem. The rest could be a hardware or software problem.

    Method 1:

    Lets start by doing a reset to coercive. Follow these steps:

    1. Unplug the notebook (remove power cord), then remove the battery.
    2. Disconnect all USB devices and the connections between the USB ports.
    3. Let the laptop only for several minutes.
    4. Then plug the power cord without connecting the USB devices. Then replace the battery.
    5. Plug each device in turn, allowing them to load the drivers of devices one at a time (plug in the appliance and wait its loading all its drivers before installing the next USB).

    The computer recognizes the USB ports? All of them or none of them?

    Method 2:

    Open Control Panel, Manager of design. Click the view tab, and then click Show all devices. From there, you can remove all instances of USB devices and restart the computer to see if the problem resolves. Repeat this procedure with the wireless adapter (uninstall and reinstall, ensuring that there is only one instance of the wireless adapter).

    Method 3:

    Create a new user account by following the instructions in this article:   http://windows.microsoft.com/en-US/Windows7/Create-a-user-account . Does this solve the problem?  If the problem is resolved in a new user account, this means that the old user profile is damaged. Here is the link to repair a damaged user account: http://windows.microsoft.com/en-us/windows7/Fix-a-corrupted-user-profile.

    Try these methods and post your results here. I'll be here waiting for the results!

  • Saving ink by powering off the power when you are not using it?

    I have a HP Officjet 6700 running under Windows 7 64-bit and read that turning off your printer when you don't use to save on ink. Is this true?

    Hello

    Right, but turn off will save a bit of power. Inkjet printers need ink more when you turn very often.

    I hope this helps.

  • Is there a need or a way to turn the pencil off the power when you do not use?

    Is there a need or a way to turn the pencil off the power when you do not use?

    Unfortunately not. The best thing is to turn off bluetooth. However, you will need to re - pair the iPad and the pencil again by plugging in the port of lightning. When not used the pencil of apple do not lose a lot of power.

  • Satellite A60: Sound quality poor microphone when you use the USB phone

    I have problems with the microphone/recording quality on my A60 including but not limited to situations when you use a USB phone. Talk to the USB phone produces a lot of static when it is used with the A60, which is not the case when I use another laptop.
    The two laptops have the same VOIP software and "simplyphone.

    Any ideas what could be the problem? Drivers?

    Toshiba support suggests to see if a system restore will improve things, but I am reluctant to go there for a questionable result.

    Hello

    I don t think that the driver update will help you. The operating system uses the simple common Microsoft USB drivers. I think we should get the problem somewhere else.

    You can try to disable the power save option in-USB hub-> properties > Device Manager. I noticed that if energy saving is enabled on ports USB some external devices could not work with maximum efficiency.
    In addition, you should disconnect other USB devices during the test the USB microphone.
    I think that it of not impossible that some external USB devices might have a negative influence on the use of a USB microphone.

    PS: I found a site interesting on tests of micro USB

  • Satellite A30 crashes when starting the Bios when you insert a USB

    My A30-104 laptop hangs when starting the bios, whenever I insert a USB key into the USB port.
    The only message that appears at the bottom of the screen and the message is something like this:
    Press F12 for the boot configuration or F12 for...

    Pressing F2 or F12 does not change the start state.
    Note that Microsoft XP Home SP2 is installed on the machine.
    No idea why startup is suspended?

    Thank you

    Maybe the laptop tries to start the USB, but it is not possible to
    It's just a suggestion, but I remember that something similar happened to a friend of mine.
    The printer is connected to the USB and the laptop could not start in the OS.

    Well, maybe we can solve this problem on the laptop you by changing the boot order in the BIOS.
    Please enter the BIOS and change the order on the disk HARD - CD - etc.
    Make sure that the HARD drive was chosen first

  • Move-vm can migrate a powered off the virtual computer to a DRS cluster?

    When I try to move-vm has propelled off VM to a destination of DRS cluster, he says that he cannot migrate a powered off the virtual computer to a DRS cluster.   I can explicitly name the destination of the host and it works, but that defeats the purpose of using the DRS and forces me to script on the destination hosts.

    I do something wrong or I would be able to migrate a powered off the virtual computer to a DRS cluster?

    Thank you

    -MattG

    Hello, MattG-

    I get the same behavior as you when you try to move a VM PoweredOff to a DRS cluster, specifying the cluster as the value for the parameter - Destination to Move-VM (using PowerCLI v5.1 Rel 2 v5.5 Rel 1).  Not quite what I expected.

    To work around the problem, and without having to appoint a particular host as destination, you could use some Get-Random, do something like:

    Move-VM myVM0 -Destination (Get-Cluster myDestDRSCluster | Get-VMHost | ?{$_.State -eq "Connected"} | Get-Random) -RunAsync
    

    Who should receive the machine said cluster and on a host that is in the connected state.  A subsequent operation to the market (whenever do you eventually) should then see DRS power on the virtual machine on a suitable host in the cluster.

    Maybe the dev team can comment if this behavior is the expected or desired.

    Anyway, how does do for you?

  • Satellite M30x-174: cooler starts denoising when I connect USB mouse

    Hello

    I bought a toshiba satellite m30x-174 a couple of months, and I have a problem with it.
    When the computer is turned on (without the mouse into the usb port), but not ongoing enforcement programs other than windows, it runs nice and quiet, but when I connect to my mouse starts denoising. I think it's the cooler that begins. Then when I remove the mouse stops denoising again. I tried with different mouse, but it doesn't change anything.

    Nothing changes in the windows task manager when the mouse is connected/disconnected.
    Hope you can help me.
    Concerning

    Hello

    It is very interesting occurrence. I use as external I smile and have him try connect or disconnect. You are absolutely right. In Task Manager there is no change.

    Sorry but I have no explanation for that matter. I hope that the radiator is not too strong. In any case, in my opinion I n t see what a certain kind of problem.

  • Satellite Pro M70 freezes everytime when the USB port is used

    Satellite Pro M70 (SPM76) crashes every time when the USB port is used.
    The mouse works, but external HD/Extarnal card sound/Memory stick causing the laptop to freeze. All the drivers are installed right, they are the most recent and have no trouble with other users.

    The devices are all compatible. Service pack 2 is installed, and all the hardware drivers on the toshiba have been updated... again, same problem.
    The toshiba is about 2 months old and have had this problem since I got it. First I thought it was the drvers, but I cleared of all (?) other options but the USB ports.

    Hello

    Believe me, that's not easy to say what the problem may be. It is important to see if the problem occurs because of hardware or software may be. I recommend you to backup all your data and reinstall the unit using rescue media. On this way the unit will be factory settings and will be clean preinstalled. Test your USB devices and see what happens.

    Try to use some standard like USB stick or external HARD disk parts, because in this case, you must not install any drivers please. If you use other devices like USB webcam with own software and drivers, it is possible that something goes wrong, but what. On this path, it is not possible to say.

    Hello Richard

    It will be interesting to know what devices you connect to the USB ports and devices has own power supply.

    It's really not easy to say what is happening here. Perhaps some device needs a little longer to be recognized. Please let us know what devices you use.
