G510 - Big roblem - Nothing is shown after log in screen

Hi Experts,


I have a serious problem with my laptop G510 (Just 2 months old).


After starting laptop, log in screen appears as it used to be. But when I provide my credentials nothing is shown after that. Log in works fine, no error with user name or password. But after that it is screen. Nothing happens after that.


If I press ctrl+alt+del task manager shows up and I can see all process are running in background. So not sure what is going wrong here?


And when I try to call spport centers near by me, no one is receiving my call. It will be really great if some one can


a. Provide any solution to above mentioned problem

b. Or provide best way to contact lenovo to get this machine replaced.

Re: G510 - Big roblem - Nothing is shown after log in screen

Hi Suhas,


Welcome to Lenovo Community Forums!


I’m sorry to hear that your G510 Laptop is booting to black screen, I suggest you to perform the Flee-Power and BIOS reset. Below are the steps to check and resolve the issue:


  1. Remove the battery and any other peripheral device connected to the computer.
  2. Hold the power button for 10-15 seconds and then connect only the AC Adapter and try to turn ON the computer.
  3. If the issue persists even after performing Flee Power then resetting BIOS to its defaults should resolve the issue
  4. Now access the BIOS menu turn OFF the computer and click on the NOVO button located beside the power button.
  5. Then to reset the BIOS to its defaults, click on “F9” Key and select YES.
  6. Now click on “F10” Key to save the changes that are done in BIOS, restart the computer and check if the issue is resolved.

Hope this helps!!!


Do post us back for further queries.


Best Regards
