Miss acer aspire 5720z log in password

not sure if this link will help you out but have a look... can remember my password for my acer laptop Google Search

hi.
if a (any version of) windows don't start up or got password on log in window, the best way is to
put the windows installation disk and let the notebook boot from the disk and then choosing "Repair my Windows" option.
this work is the safest way to solve the problem.
however there are many faster ways to do this but they may greatly harm your notebook!

unplug the computer and take out the battery on the motherboard

You can purchase the software to crack the password from http://www.password-reset.com/index.php. It cost $19.99. It is a great deal. Technicians charge around $100 to crack a password.

Your model acer link for downloads:

Remove the battery . Short the grounding strips made for this purpose on the mother board,or the battery terminals,if you can't find the strips.  Reinsert the battery and the pass word will be gone. 

There are two places when you may be asked for a password - can you please clarify which one it is.

1. The BIOS password which will ask you for a password BEFORE you see the Windows loading screen
2. The Windows password, which will ask you for the password after the computer has started, but before you can see your desktop.

There is a reasonably easy solution for both of these.
