My phone gives me a black screen with a blue box and after that I entered a password for 3 times... It gives me: 90850119 system off. Please help its urgent.

Steps to follow:

1. use the posted above unlock code to access the BIOS

2 disable all passwords that are enabled

3. If the request for current password - enter the unlock code

4. for the new password, simply press the ENTER key

5. repeat the same thing to check the password column.

6. then exit the BIOS saving & exit option to save the changes.

Troubleshooting:

Incase if the password does not work please try a Hard Reset as follows.

1. power off the laptop

2 disconnect the power adapter and remove the battery

3. press the Power button for 30 seconds

4. connect the power supply/AC adapter (leave the battery for now) & start Notepad

5. If now see you a password, please enter the same password that I've shared before, & press on enter
