No Audio output device is installed

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

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.

Features
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 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.

Update the Mouse Driver

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."

Check BIOS Fixes

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.

Compatibility

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.

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.

In that case have the jack checked at a good computer shop. You need to have the jack resoldered as soon as possible.
