Your hard drive should be split into 2 partitions C:\SYSTEM & D:\DATA. You access the Recovery Partition by pressing ALT+F10 immediately after powering up. This will restore the C:\ partition to factory default BUT leave the D:\ partition unaltered.
In order to make best use of the Recovery Partition, the user should move essential files from C:\ to D:\ prior to invoking the recovery. So - how to do that in your case...
You could download and burn to CD an image of the UBCD - the Ultimate Boot CD. You BOOT from this disk and it runs inside its own operating system, leaving your laptop hard drive 'out of the loop', so you could then transfer important data files to the D:\ partition in preparation for the recovery.
However, UBCD also contains a suite of diagnostic tools and there is every chance you could restore your system 'as is' without invoking any recovery to factory default.
I suggest you try examining your drive with the HDD tools on the UBCD first.

You can also use it to run antivirus scans from, when a hard drive won't boot on its own.
