You normally find the option under START - CONTROL PANEL - MOUSE

But by default, if you touch on the mousepad which is located in center of the keywords.. your mouse should be activated.

There can be many reasons why this happens but one of the common reasons is that your sound drivers are outdated or corrupted,, to fix this problem go to control paniel, hardware and sound, device manager , and in there find the sound drivers, if there is a little yellow signal its because they are corrupted, you must right click it and uninstall, and reboot,,it should fix them. Another problem could be your playback program it doesnt have the codecs needed to play the sound,, i recommend you downloading Vlc Player and playing dvd with that.... One last piece of advice is i recommend checking the volume settings.

if I understood well you want to disable it ..and use a regular usb mouse....the way to do it ..its go to device manager by click right on my computer than properties/hardware and device manager ...locate the device ...right click on it ..and than disable ....this will get it out from the circuit ..after that just add the mouse and install it ...
when you want to get it back do the same ...go to device manager click right on computer and choose scan for hardware changes..it will bring it back ...and all you have to do is to activate (enable )it ..

You can go into the device manager on windows from the control panel and right click on the touch pad device listing. Then select disable this device. This will stop the touchpad from working until you re-enable it again.

Try to browse the card manufacturer website, a lot of laptops dont bring the cds when sold, so if reprograming or restoring you have to download drivers from this sites.

remove the battery large.
then run on AC pack only
#1 top failure of all mobile PC is that battery, so unplug it
then test with AC pack only.
work now.? and all vents must be clean, end to end. not just fan.
there i no fuse it uses current regulator, imagine genius magic electronics fuses that never blow out, and bingo.

OK big battery out, an RTC coin cell fresh.
then fan blows.
next is BIOS, do the BIOS screens work if not the mobo is dead.
have 2 RAM stick on the 2 slots>? try one at a time
run the PC with all modules removed, (options)
remove hdd?
remove, dvd drive.
think like this. Get bios working first
learn that modules can short, and when they do the power regs shut down.
so we unplug all things to the mob,
until only 1 ram and cpu remains.
see? (this is called power overload fault isolation tactics)
even the screen only can be dead, you never mention text showing
you can test the mobo with external screen via that rear (?)_ VGA jack what if that worked, did you learn something here, sure.
this pc has tons of modules to pull, even bluetooth. wifi, sound and more. if you look at all parts inside or sold by ebay, bingo. lots

It helps to know what device model and OS you are using though the following steps for changing from pattern lock to slide are for Android OS 4.0 (Ice Cream Sandwich):
1. Unlock your Android device
2. Find the Applications menu and select "Settings"
3. Under the "PERSONAL" group, select " Security"
4. Under "SCREEN SECURITY" group, select "Screen Lock"
This will ask for the security pattern first.
5. The options for screen lock will appear, select "Slide" and you are done!
Hope this helps.
