How can I replace the HD in my ACER 1522

It seems there is a wealth of good information on this forum. Can
anyone tell me how to open up the Acer 1522 and remove the HD so I can
replace it with a bigger one. I followed the replace fan thread but it
did not go deep enough.
Many thanks for your time.

OK so I worked it myself. After trying to take he case apart and
getting nowhere Iread somewhere that it is located behind the batterey
and you just pull on the plastic tag. It worked! 2 small screws hold
th hard drive in a caddy.

Could you be more specific. I need also to remove hdd from my Acer 1522, removed 2 screws from both sides of caddy also two screws on side near heatsink but still I can not take it out. It stucks on conector sides, if I use more force I am afraid to break something
