Windows 10 1803 lock screen flash.

Hello everyone, 

I am using a laptop with Windows 10. Its Lenovo Ideapad 310. I have a password set. Yesterday,  when I tried to log in, after the lock screen came, I pressed enter but the password prompt screen never came. Instead, after presing enter, the lock screen comes back with a flash. How do I solve it? Please help me. I am unable to log in and I can't do my work.

Thanking everyone,

Anik Ghosh

Hi!

My name is German, and I am here to help you.


To resolve your concern regarding no login prompt on lock screen (without restarting), you might want to try the following troubleshooting suggestions:

* Once you are on the locked screen, press any key ( Spacebar, Enter or Backspace ), it should take you to the next page where the system will be asking for your password.

* Once you've reached the locked screen, press Control + Alt + Delete to get you to the next page where the system will ask for your password.

Hi Anik
I am Vijay, an Independent Advisor. I am here to work with you on this problem.

A. Try to boot into safe mode

Power ON your computer and as Windows / manufacturer's Logo appears, Power OFF - Repeat 3 times
Now your computer will go into Advanced Recovery Environment
Advanced Options > Troubleshoot > Advanced Options > Startup Settings > Restart
Press 4 or F4 to enable Safe Mode (5 or F5 to enable Safe Mode with Networking)
Log in once Windows starts in safe mode
See whether you able to login. If yes, come out of this and start normally.

If you are not able to boot like above, You will need to boot through a Bootable USB drive. You will need to create this on another computer which is working - https://www.tenforums.com/tutorials/2376-create...

B. Another option when you are in Advanced Options in previous step is to choose (Note - You won't lose any files in this step)
1. System Restore - This will restore your system to a point when things were working fine.
OR
2. Startup Repair - Startup Repair upgrade fixes all Windows errors and retains all files, applications and settings.

C. Penultimate option could be Reset this PC.
In Step A > Troubleshoot > Reset this PC - Keep my files and Remove everything. Choose this carefully as most likely you would like to keep your files.
All apps will be removed and windows will be reinstalled.

D. Last option could be a clean Install. This is the best method to perform a clean install of Windows 10. (If you want to rescue your files, there is a section Rescue Files when Windows Won't Start)

If you want a very lightweight guide - Start fresh with a clean installation of Windows 10

Hi anik,

Start your PC, just as Windows attempts to load (spinning dots), press and hold Power Button for 5 - 10 seconds to perform a Hard Shut Down

Do this twice

On the third start Windows will boot into the Recovery Environment and from there you can access System Repair, Safe Mode, Command Prompt . . . etc.

Please try each option one at a time, then see of Windows will boot to the login screen. . .

Go to Troubleshoot - Advanced Option - Startup Repair
See if Windows startup can repair itself

Go to Troubleshoot - Advanced Option - System Restore
Check to see if you have a restore point you can go back to

There are no system restore points, and I tried using startup repair, it showed attempting repairs, but no changes are noticed.

Actually, this is not the problem. The problem is, when the lock screen comes with a big clock on the bottom left, I press enter, the screen moves upwards, and then the screen with the big clock again comes back.
