How to change the HDD on a HP compaq 6720s

[LyriCJokeR]

I got a HP compaq 6720s too 1GB RAM and 160GB Hard drive and i cant complain about it just that having it for nearly 2 years I am upgrading ti to 4GB RAM (2 GB RAM a peace) and with a 500GB SATA Hard drive.

That should totally rocket the PC and having a 500GB mini WD Passport Drive makes it even sweeter to have a 500GB PC drive.

And to Mr. ooops1234 all i can say is...what you want more than a sweet blue light telling you "caps lock" is on? I have never had problem noticing the blue light.

I have hp compaq 6720s laptop and it has Intel centrino 2.10 GHz T8100 processor. 3MB L2 cache, 3GB RAM. Means it is a solid machine specs wise. Isn't it? Now it often has the problem of Ethernet card and one more thing that I found today is its caps lock key don't give any onscreen notification for caps lock on or off however its light works that is on the button. Please tell me solution if anybody knows. Thanks.
