Get Your Laptop Mouse to Show Up if It Disappears
Using a laptop is as efficient as a desktop computer to complete tasks, use the Internet and talk with friends on a daily basis.
If your laptop's mouse cursor disappears, there are various tricks and solutions available to help get your mouse pointer back to resume your work and current computer tasks within minutes.
And this can be accomplished without the use of software applications or advanced computer skills.
Press "Ctrl" + "Alt" + "Delete" and choose "Task Manager" if your mouse pointer becomes available, pressing the keys simultaneously.
This will allow you to close any open programs that may be causing issues with your mouse pointer.
Plug in an external mouse to allow the computer to attempt to find the device, prompting the mouse pointer to appear which may solve the problem or allow you to temporarily work with a mouse pointer.

Reboot your computer by pressing and holding the laptop's power button for a few seconds.
This will reset your laptop's current open settings and most often allow your computer's mouse pointer to reappear.

Upgrade your laptop's video and graphic card drivers (if available) to ensure the mouse pointer disappearing or flickering is not a hardware issue.

Usually pointer gets locked due to malfunction of photo diode! the diode will detect the movement of the light produced by a optical mice! Dont bother get a new optical mouse!

1. In order to fix this, you go to control panel > mouse
the last tab is called "Device Settings" click it and make sure you have "static tray icon in taskbar" selected.
(You can always remove this later.) Apply the changes and click the red coloured icon in your task bar. An option will be available called "Tap to click." Clicking it will enable you to tap with your mouse pad instead of the keys! Hope this helps you out, I know it helped my friend.

2.
In the Control Panel open Accessibility Options Icon and click Mouse Tab and than Setting.
To move the mouse pointer by using MouseKeys
If you have not already done so, turn on MouseKeys.
To turn on MouseKeys, open Accessibility Options, click the Mouse tab, and then select the Use MouseKeys check box. Use the buttons on the numeric keypad to move the mouse pointer. If MouseKeys doesn't function, press NUM LOCK, and then try MouseKeys again.
To move the pointer horizontally or vertically, press the arrow keys on your numeric keypad.
To move the pointer diagonally, press HOME, END, PAGE UP, or PAGE DOWN on your numeric keypad.
Notes To open Accessibility Options, click Start, click Control Panel, and then double-click Accessibility Options.
To specify whether NUM LOCK must be on or off for MouseKeys to function, on the Mouse tab, click Settings, and then for Use MouseKeys when NumLock is, click On or Off.

If you have a manual for the notebook, check to see if you can use the function key and the similarly coloured key on the keyboard which enables/disables the touch pad. Usually you can disable the mouse pointer touch pad with this FUNCTION key + MOUSE key when pressed together. Often these keys have the same colour (usually blue). The purpose is to disable the touch pad when you are using an external USB or wireless mouse, then you press the 2 keys again together to enable the touch pad once you have removed the USB/wireless mouse.

If that doesn't work, borrow a USB mouse and attach it to your notebook to use temporarily while you diagnose the problem.
