Black screen, computer runs and hdmi port works fine

Hi,

I'm having an totally updated Yoga370 runing Win10(64)

Now to the problem, yesterday I was using the hdmi port, disconnect the hdmi and shutted down the computer. No problems.

Today I started up the computer, no Lenovo logo was shown during startup, but it runs, was able to login with my finger.

Made a couple of reboots.

I attached the hdmi and can use it but still with a black screen.

 

Any suggestions?

It's only 2 years old.

 

Best regards,

Magnus

Hi @Magnus56!

 

Welcome to Lenovo Community Forums.

 

When did the issue start? Kindly power on the laptop and move the screen onward/backwards and observe if you'll see any changes. You may also access the BIOS settings and check if the screen will work. Click here on how  to access BIOS. 

 

If still no display in BIOS, it's possible that issue is likely to be hardware related and we suggest that you bring your device to our authorized service providers to further diagnose the problem. Click here to see the list (filter by country).

 

Regards,

Re: Black screen, computer runs and hdmi port works fine

Hi Van_Lenovo,

thx for reaching out!

 

When it started?, it was just a week ago, out from the blue.

Since it was no change when turning the display around.

I went for another path.

 

I read in the manual about the beep feature, so I tested that out, if the beeps was there by pressing the Fn-key when the Laptop was runing. Since the beeps was there I downloaded the app and got a 0288 code with a suggestion of two actions.

I was able to disconnect both display cables from the motherboard and only one from the display. Waited for 5 minutes, reconnected them. 

 

And it all now works fine.

 

Somehting that worries me is that this Laptop is only a couple of years old and the screws where loose inside the unit.

 

But I´m happy, Laptop is now working again.

 

Br,

Magnus
