Hi, none of these suggestions work my compute. I have a laptop 510s and it just decided to go into a black screen. Could have been during a sleep mode period. But i cant get it to work properly even after downloading and reinstalling windows. It goes to the black screen at different parts of the installation or after the installation. How do i prevent this from happening. I have done the following:

Reinstalled windows a few times

Disconnected the battery and discahrge the static a few times

Reset the PC

Use USB recovery device

Tried the safe mode which never worked

Run startup repair which tells me it cant repair the issue, and

Used the command prompt to try and run diagnostics but it did not work.

When it installs it goes al the way to the windows start window but when it finishes the install and restarts it goes black at the welcome window or at the Lenovo start window.

Any help with this will be appreciated.

Thanks

Andy
