First, always go to the manufacturer's website which relates to your product or device. Always provide the make and model number of your device or laptop along with the OS version you're using as it provides the information which applies to getting your question answered quickly. Meanwhile, I would try booting up your laptop in SAFE mode which will allow you to access your laptop. I would then go into the "USERS" area and click on your user name and then try and change your password. This area usually provides "a HINT" which you may have provided when you first entered your password and it may also help you remember the password .......... good luck.
