First, make sure your trackpad button is enabled... if that isn't the problem, then go to your device manager and check that there isn't a driver issue, if there is you'll see a little yellow triangle next to the category "Mice and other pointing devices".
If there is an issue, highlight your touchpad, then right click and choose "Uninstall Driver".

After the driver is uninstalled, go to your start menu and shut down the computer, then restart it and the new driver should automatically reload into the system.

If its not a driver issue, then its the touchpad itself and you'll have to contact a technician for repair/replacement.

When i switch on my hp probook 4420s it cannot load the operating system but keeps restarting


Try going to bios by pressing del while starting. Check the boot sequence if your HDD is on the list and selected as primary. You can also try HP recovery by pressing F11 key as soon as you power on the laptop.

AC adapter fine also battary fine but HP 4420s dont charging


If that is true the charging circuits on the motherboard will be the problem, "a rare situation" so long as the laptop powers up using the adapter and the charging voltages are missing in the computer terminal where the battery plugs in then this would apply.

I need to turn off the mouse pad on my hp probook 4525s, do I need to install any special softwer or what to do?


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.

I have a HP Probook 4420s, but the DVD-RAM Drive is not working, when I check on device manager it's there but with a yellow exclamtion mark, I tried uninstalling then installing back but same issue.Help...


The yellow question mark tells that the drivers are not installed. Try uninstalling them and re-intalling them.

the drivers can be downloaded from internet from the HP's website. GOOGLE your laptops name with driver and it would show up.

Hope it helps. here's the link to hp website-us: http://www8.hp.com/us/en/support-drivers.html

I purchased a brand new HP Probook 4420s two day before, today I get a problem on that. My screen get off. I didn't show anything. please help me what to do..........


Hi,

I think you can try this step and see if its going to turn on.

1. Remove the battery and Unplug the AC power.
2. Press and Hold the power button for 1 minute.
3. Put it all back.
4. Check if the machine would turn on.

If it doesn't work means there is a hardware problem on the machine. I recommend to call the manufacturer since that's a brand new machine.

Hope it helps. Thank you for choosing FixYa.
