A red light sometimes appears on the touch pad and freezes the mouse.   Although I have unlocked it, I don't know what I pressed.   Can anyone help?   Thanks

Hi,

Some touchpads have a 'double tap' toggle that will turn them on or off.  Try the following to see if this applies to you.

Double tap the top left corner of the touchpad - if this illuminates the red light on the touchpad all you have to do to turn it on is to double tap this area again.

Not the case here - it's a mystery, but many thanks anyway

Hi,

Can you post back with the following.

1.  The full Model No. or Part No. of your notebook

2.  The touchpad manufacturer ( ie Alps, Synaptics ).

3.  The operating system you are using.

You are very kind.   I hope that this is what you want - I know nothing about computers.

1.    584037-001

2.    Compaq (i think).   It is incorporated on the keyboard

3.    Windows 7.

Since we last spoke, I could hear sound, but the whole screen was blank.   Don't know how I got out of it!

Hi,

The Model No. and Part No. are located on your Service Tag on the underside of your notebook - these are shown as 1 and 2 on the example in the following link.

Can you post back with these details.

This is small and very difficult to read.   I think the number is X1696072.   If this isn't right, thanks anyway.   I'll get on to technical support on Tuesday.   I'm obviously pressing a really simple thing.   Thanks anyway

Hi,

I know what you mean, it's not the easiest thing to read - do you have HP Support Assistant installed on your notebook?

Thanks

Ok, If it's any help, HP Support Assistant should show your Product Number - see Here.
