Have you made backups of any important documents>>files/folders?
If not, do it now
As much info i can find, your computer comes with 120 GB - Serial ATA-150 - 5400 rpm hard drive
And probably a generic drive
Normally 2.5" >> 9.5 mm
As indicated by the following link
http://www.drivesolutions.com/cgi-bin/shop...;itemid=tol1415Take in mind, Drive Solutions is recommending Sata 300 or 150
Yours is standard 150
I'm not sure if all laptop drives are backwards compatible
Sometimes just changing a Jumper pin will control the speed
You may think about going to a 7200rpm
Not sure if your planning to ghost your drive, or reinstall if you have the recovery disks
That is your option
As far as removing the Harddrive, I couldn't find a clear picture of your exact model
The closest I could find is the following link

NOTE: Ensure to unplug the laptop from power source and remove Battery before removing harddrive
