Unable to press any key during Start Up

Question

I need help regarding my notebook HP Pavilion dm1. Its a very long story but I will try my very best to cut it short. So here it goes.....
My younger sister got that laptop from her school. So about installing of things including Mircosoft Words, Adobe Flasplayer etc, was done by my sister's EX fiance. For months everything when smooth only up till now. I realize the User was under his name. i couldn't seek my sister's EX fiance as they broken off 3 months ago and is no longer contactable. Everything I do, including trying to update the notebook (was alerted by the notebook itself via a pop-up window at the bottom corner right hand side), it seems that I couldn't update. Now even icon such as Google Chome, Safari even the HP webcam is not functioning. I tried to update my iPhone via iTunes in the notebook like I normally do, but now, it says I need to update the notebook to its latest version. How am I supoose to update when I got problem updating? You know what I meant hopefully. I decided to Restore everything back to factory setting (thinking that it might help).
So here comes the problem...
I research about how to restore the notebook. Was written that when I switch on the notebook, I have to press ESC button. I did as written. When I am already at the Start Up menu, I tried pressing fn followed by f11, nothing happen. I am still stuck on the same page and after 1 minute, every button i press seems to beep.
So I have a few question to ask.
1) What is actually now the problem?
2) How can I restore back the laptop to factory setting?
3) Why I don't seem to be able to press any button during the time I was at the Start Up menu?
4) Why can't I update the notebook to its latest version?
PLEASE HELP!! ITS URGENT AS MY DEAR YOUNG SISTER HAS ASSIGNMENT TO DO VIA HER NOTEBOOK!!

Answer 1

Not entirely certain as to what the message of updating to the current version is in reference to. The context of the message could reveal more about it.
However, I do recommend doing a system recovery back to the factory defaults.
You mentioned pressing the Fn + F11 key. You should just press the F11 key by itself.
This should get the recovery process started.
NOTE: Backup anything that is important before continuing. A recovery will erase all files and get it back to an out of the box experience.
1. Power off the notebook completely.
2. Power the notebook on.
3. Press the F11 key repeatedly as soon as you let go of the power button.
4. This should eventually bring you to a black screen with a grey progress bar at the bottom saying windows is loading files. At this point, you can stop pressing the F11 key. Pressing the F11 key repeatedly, about once a second, is needed as there is a small window to press the F11 key and Windows will load normally instead of the recovery. So, just press F11 about once a second and it should get the ball rolling.
5. The recovery manager should load shortly giving you all the options to do the factory reset.
After you are back into Windows, perform all Windows updates (there will be a lot). If you need an anti-virus program, Microsoft provides Microsoft Security Essentials at no charge. I recommend having an anti-virus software over none.
Let me know what happens with the recovery process listed above. If you get any error messages, be sure to report that exact error message back.
Also, what is the exact model of the notebook? Knowing the exact model will help in the event the standard procedure does not work.
NOTE: Do not provide the serial number.
