I have a toshiba satellite and after the most recent windows update my external mouse stopped working and says driver malfunction when i plug it in... i have tried everything system restore driver updates... and still notihng.. but my i phone plugs in and works fine i have even tried 3 other styles of mice..

a laptop, and internal kbd dead. (or using external, unstated)
in device manager, lick keyboard.
right click update driver now.
you must be internet connected now or PnP will fail, 1/2 the time.
if that cant fix it, it needs service.

try owning a real external keyboard, USB
plug it in, problem solved in 10 second flat.

When the curser freezes, first press the windows button to see if the entire computer is frozen. The windows button is in the lower left of the keyboard near Crtl and Alt buttons. If the computer is still working, then i would start with the software that is running the mouse. I think Toshiba has their own proprietary software that runs their mouse pads. Try to update the software through Toshiba's website. If that does not work, i would try updating the driver for the mouse. If that does not work, you may want to contact Toshiba for more detailed assistance.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/jason_76c7b1512fdc05a2

Press the "Fn" and "F9" keys simultaneously.
Test your touchpad. If it works, it was simply disabled. Press the same key combination any time you want to toggle your touchpad on or off.
Plug an external mouse into a USB port on your laptop if the key combination didn't work. Follow onscreen prompts to install the mouse driver--if necessary. You can also move the cursor using the "Tab" key and the arrow keys, as well as click by pressing "Enter" until the mouse is operational.
Click the link in the Resources section if you are using a Toshiba Satellite with Windows Vista. Follow the onscreen prompts to download and re-install the driver.
Open a web browser and navigate to Synaptics.com if you have a different Toshiba model or operating system. Synaptics brand touchpads are used in all Toshiba laptops, and this site provides a generic driver.Hover your mouse over "Support" on the top menu, then select "Drivers" from the drop-down menu.
Select your operating system from the list provided and download the generic driver
Follow the onscreen prompts to install your new driver, and then test the touchpad again. If it still does not work, take your laptop to a licensed repair technician.

Contact seller. I'm a bit confused? Brand new Windows 8 install then Uninstalled ? Why? Is Win 8 still installed?

If you have the disk or driver for keyboard then reload it.
If not then use the mouse and click on the Start button, use the mouse's right button on Computer (My Computer). Select Manage. When the Computer Management console appears, Select Device Manager. Expand the Keyboard Section. Right Click on your computer name and select Scan for hardware changes.
If this fails to reload the driver then right click on the keyboard item that says Unknown and select Update Driver Software.

Toshiba has released a few different advisories related to its Satellite line of laptop computers having keyboard problems. Remember that damage caused by liquid or physical damage is not usually covered by warranty.

Bios Fixes
On Satellite models 1955-S801, 1955-S802, 1955-S803 and 1955-S804, the BIOS (system utility setup program) had trouble reading the firmware for the wireless keyboard. BIOS version 1.40 repaired this problem. The BIOS flash program can be downloaded from the Toshiba website. http://askiris.toshiba.com/ToshibaSupportSite/search.do?cmd=displayKC&docType=kc&externalId=286356xml&sliceId=&dialogID=124900040&stateId=0%200%2084585964 b> Satellite 1955 Text Anomaly b> Toshiba reported a strange, software-specific problem between the Satellite 1955-S801 and S803 computers and Microsoft Word and Excel. Users who held down the shift key for more than five seconds while using the arrow keys would see their highlighted text disappear. The only provided solution was to use an external keyboard attached with a PS/2 connection or to release the shift key if pausing while highlighting in those programs. General Troubleshooting for Satellite Keyboards b> For general concerns about the keyboard -- if it doesn't appear to be working -- try these few steps. Use the keyboard before Windows loads: hit F1 on the first screen that appears after turning the system on. If they keyboard works here, it's probably a Windows problem. Try attaching an external keyboard; if it works, the internal keyboard is likely broken.
Toshiba Laptop Mouse Problems
Some symptoms that occur with Toshiba laptop mice include jumping and vanishing pointers. These situations have occurred after software upgrades have been made. The problems can often be solved by following basic mouse troubleshooting methods. Overall, Toshiba laptop mice contain the basic functions characteristic of the USB variety.

Function b> The mouse device is used to move, open, delete and otherwise connect with items available on and through the computer monitor. In Toshiba laptops and many others, the mouse pad replaces the point and click USB mouse device. This enables the mobile computer laptop to be more compact, portable and ready to use. b> Features b> The mouse pad on a Toshiba laptop is located in the middle, directly below the keyboard. The control buttons, both primary and secondary are situated below it. The primary key, on the left, represents the left-click button on an USB mouse device. The secondary key on the right represents the right-click button on an USB mouse. This button is used to pull up the short menu of an item after selecting it. Update Keyboard Driver b> Many Toshiba mouse issues can be solved by updating the driver. The driver enables the mouse to function properly. Update the keyboard driver first to increase mouse and keyboard device compatibility. To complete this task, click "Administrative Tools," accessible from the Start menu. Next, click "Computer Management," and then select "Device Manager." Click the "Keyboards" expansion node to bring up the list of installed hardware, and then right-click on the keyboard that is in use. If the "Update Driver" option is available, click on it. Otherwise, select "Properties," go the "Driver" tab and press "Update Driver." Device Manager is a useful tool to update, rollback or uninstall incompatible drivers. b> Update the Mouse Driver b> Update the mouse driver by following most of the instructions in the above section, "Update Keyboard Driver." However, after selecting "Device Manager," click the expansion node next to "Mice and other pointing devices." Select the current mouse device in use and right-click on it. If the "Update Driver" option is available, click on it. Otherwise, select "Properties" and go to the Driver tab and press "Update Driver." b> Check BIOS Fixes b> Some older Toshiba laptop models require BIOS (Basic Input/Output System) fixes. Most of the downloads are available from their website. Since, the BIOS chip is the liaison between the hardware and software, any issues should be addressed promptly. Symptoms, such as erratic mouse behavior or the pointer disappearing, are signs of a need for a BIOS fix or driver update. b> Compatibility b> Toshiba and most Microsoft Windows products are compatible. This is vital when it comes to updating necessary drivers needed for continual operating system function. The service packs they approve of are listed on their website. Hope this helps.

does other usb mouse working with it ? ( just to make sure if driver is not missing ) Goto control Panel > Mouse > at window, Device Settings Tab , make sure "Disable internal device when external device is attached" is unchecked.

update ur sd card driver, may be it is cause of windows download ,

It is possibly an error with the driver. To check, go to Control Panel and then the Device Manager. Look for the section labeled "Mice and other pointing devices" and look for "Synaptics PS/2 Port TouchPad" or anything which has TouchPad in the title. If it has a weird yellow triangle with an exclamation point, there may be a driver problem. Double click on the device, choose the Driver tab at the top and choose to Update Driver. Choose to automatically search and hopefully you should find, then install, the driver.
Have you recently run any Windows updates? If so, that may have messed up the driver. Instead of choosing to update the driver, choose to roll it back instead.
My solution is only for a bad driver. I hope this helps you and apologize if it does not.

Here are some possible reasons why your Toshiba Satellite P15 mouse pointer is sticking or stalling when the laptop is on AC power:
Driver issue: The touchpad driver may be outdated or corrupted. Try updating the touchpad driver to the latest version.
Hardware issue: The touchpad itself may be faulty. If the problem persists after updating the driver, you may need to replace the touchpad.
Battery issue: The battery may be causing interference with the touchpad. Try removing the battery and see if the problem goes away.
Software issue: There may be a software conflict that is causing the problem. Try disabling any recently installed software to see if the problem goes away.
Here are some troubleshooting steps you can try to fix the problem:
Update the touchpad driver:
Download the latest touchpad driver from the Toshiba website.
Uninstall the current touchpad driver.
Install the new touchpad driver.
Disable touchpad enhancements:
Go to Control Panel > Hardware and Sound > Mouse.
Click on the "Device Properties" tab.
Uncheck the box next to "Enhanced pointer precision".
Clean the touchpad:
Turn off the laptop.
Dampen a lint-free cloth with alcohol and gently wipe the touchpad.
Let the touchpad dry completely before turning on the laptop.
Update Windows:
Make sure your computer is up to date with the latest Windows updates.
If you have tried all of these troubleshooting steps and the problem persists, you may need to contact Toshiba customer support for further assistance.
