Try installing the latest WEBcam driver.
You can download the WEBcam and device drivers from the Compaq/HP WEBsupport/download page. Make sure you select your model laptop and the Windowsdrivers you require and install them. Click on this link to download thedrivers: -

Hello,

you do not need to install any special software.

Here is what you have to do to turn off the mouse pad of your hp probook 4525s;

Turn on your hp probook 4525s, wait till it boots completely.

Click start,

Scroll to Control Panel select Control Panel.

Under control panel, (you will find a Mouse icon), click Mouse and a dialogue box will pop out.

On the dialogue box, click "Device settings".

Under device settings, you will find "Synaptics Touchpad..."

Highlight the "Synaptics Touchpad..." by clicking on it once, then click disable.

By now the mouse pad should be disabled. Apply the changes for it to take affect.

To enable follow the same procedure and click enable using an external USB mouse.

Yours sincerely.

During the boot process you will see on the screen to press a certain key to enter setup
Press and hold that key during the boot up process to enter BIOS you can load failsafe defaults or load optimized defaults ,press escape then press f10 to save to cmos to restart
or
During the boot process tap the f8 button three times this will boot into safe mode where the only things
working will be your mouse and keyboard enabling you to attempt to repair your computer
