Problem with HP pavilion dv4-1117nr touchpad pointer & key

[obhro]

I was browsing on the internet a few hours ago and all of a sudden it hanged. Tried to shut it down by pressing the power button but it did not work so took off the battery. When I turned it back on, I selected the safe mode. The cursor was moving fine as I used the touchpad but the left key didn't work although the right key worked. So I restarted in the normal mode but the problem persists, & additionally I noted that when the computer is switched on, there is a dotted dragging box (don't know if there's a technical or common name) along the cursor. The kind that happens with left-click and draggin.

I was thinking somehow the touchpad key is jammed but the tapping on the touchpad option is not working either! So it's a left-key mechanism fault as a hole.

Right now I am using an external mouse to work.

Any suggestions that don't involve hardware checking?

Did you find a solution to this.

I suffered a similar problem on my machine

HP pavillion dv4-1100ea s/N: CND8421Lw7 running vista home.

I was using an application and left click stopped working and cimputer was crashed I had to restart a few times before it would run. I have not yet tried a new driver as I personally think it is hardware related. If there is a software bug issue with this I woudl apreciate HP Tech given some feedback on this problem as it does not appear to be a one off.

The most annoying thing is I bought laptop 05/12/2008 and the fault occured 07/12/2009 which is a very annoying I am not sure if anyone will do anything to help or will care!

broken mouse keys used to happen on cheap laptops back in the 95 no excuses really for such and key hardware feature to fail arfter such a short time.

I have the same problem with left button..... it will lock the cursor in place... need to press the off/on drag window button and it will free the cursor.   The click of left button does not work to copy/paste text and other material.   I called HP they deleted driver, then did bios, same bios rev and stil same.   They wanted restore and I said research this more and let me know what the fix is...    I will read the drivers and updates and see what I found.  

I found lots of posts like this the left button does not work and looks to be software.  

I am on the way to store now to for  exchange and see if new box unit does the same.   If so I am asking for a refund.

This looks to be pretty prevelant.
