Screen says type password to decrypt storage...need help asap on on to fix this

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.

Make sure your talbet is OFF the do the following PRESS Power on & Volume button TOGETHER once the writing appears let go of the buttons . If that doesn't sort the problem go to YOU TUBE type in your question and a Video should appear showing you what you have do the solve your problem . Make sure you have tablet to hand and you can go through it with the video .

Look in the manual for the factory password..
Something like Admin or password or0000 or Android maybe

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.

Recommend a hard reset of the tablet, so you can set up a new password.
