E480 display does not turn on

2019-06-01, 4:18 AM

Hi there,

 

I recently purchased this E480(i5) just a month ago, and I am having issues with the display not turning back on after key presses.

 

Problem happens when:

1. Display turned off after idling for 2 minutes (Turn off display after: 2 minutes is set in Windows 10 Power options)

2. Press keyboard or mouse

3. Screen stays black

4. Had to force restart, I do notice that there is significant battery drain in a short amount of time when the display is turned off.

 

Problem does not happen when:

1. Set "Turn off display after:" to "Never", Leave "Sleep after:" at "15 minutes"

2. Laptop goes to sleep right away after 15 minutes and the power button now blinks.

3. Press keyboard or mouse

4. Laptop wakes up successfully and I am greeted with Windows login screen

 

Troubleshooting:

- made sure hybrid sleep and hibernation is turned off

- reinstalled intel graphics driver

- updated all driver and bios(1.32)

- Ran hardware scan in Vantage, no issues detected

 

Windows version: 1809

 

Anyone has any idea why this is happening? Thanks in advance.

Hi maxim45678.

 

Thanks for reaching us here in our community forums.

 

We'd like to further isolate the issue, could you try disabling the fast boot? Here's how:https://support.lenovo.com/us/en/solutions/ht501793

 

Also, try connecting the laptop to an external monitor and see if you'll experience the same thing.

 

Kind Regards.
