Is BitLocker messing with you?
You cant log in or does not even let you in even you type correct?
First, remove the battery (make sure it has no battery built-in).
Then make sure no power charger is not connected.
Then press the power button for about 20 sec (one Mississippi two Mississippi three Mississippi and so on). Nothing should happen you are draining the computer on power if it does startup, then you need to start over you have missed something.
After about 20 sec you can plug in only the battery and power on.
Now you can type in the password and can get past BitLocker.
When that is done you can plug in power charger if you need to charge the battery.
To many attempts and need to get hold of your recovery key?
