How do I found or reset the password

You must do a factory reset to bypass and replace the lost password. All stored data except what was loaded on it out of the box will be lost.

If you do not have the password I wonder why, someone had to input that when the notebook was set up new, it doesn't just magically appear. In any event you must do a factory reset to overcome a lost password, this will wipe the tablet clean except for the software installed by the factory/manufacturer.

If you never decrypted it, and your PIN does not work, then you will likely have to do a factory reset for the device. I would suggest you call the manufacturer first, in case there is a product specific code help they can give you, otherwise I found this page which includes methods for a Factory reset for many models.

I hope it helps, but be aware that any data you stored will be lost, in the process, excepting anything stored on an external device.
