How can i unlock F2 set up on my Emachines E525 if it ask me for a password but dont have it

Go to any Mcdonalds and try your WiFi. If that doesn't work, your WiFi hasn't been set up.

Do you have internet service? I would call your internet service provider and talk to their service department, when you get on your own computer. They can get you going.

re start your laptop then while it was rebooting the system press delete in the keyboard. the bios set up will appear then you can change the administrator password or delete then save the settings and then re start your laptop.

Just hit the set up key as your machine boots up, usually, F2-F3 or F8.

Go to safe mode using the up-down arrows and where it says set/change password, simply hit the enter button, enter a new password in and close, using the save function.

You can now use that new password and are now officially the administrator!

Or else, you need some Windows password reset program to help you do that job.
