G50-70 Laptop Screen Flashes When it shall start up and stop there.

I have a G50-70 laptop and recently whenever I start the computer the screen flashes very dimly. The power light is on when this happens.

The computer will not continue to start and will blink weakly with a black screen.

Can hear that it is on, but still black screen as it comes one weak flash approximately every second.

I have also tried to connect to another PC screen but this one did not get in touch

Anybody who can help me?

Hi fralor!

 

Welcome the Community Forums.

 

Please do a power drain by removing all connected devices (ac adapter, USB flash drive, etc.), shut it down and hold down the power button for 60 seconds. Turn it back on after a few minutes and observe. If same issue, access BIOS by following the steps here, https://support.lenovo.com/us/en/solutions/ht500216. Load default settings by F9 then save and exit by F10.

Unfortunately, this does not work either. I'm not getting into BIOS because the screen is still black and flashing weak.
Possible there may be motherboards that are incorrect.
I have also tried to connect with external monitor, but I do not get any signal on it.

That could be a possible reason why this happens. Normally, for hardware related issues, we recommend to have the computer to be examined and repaired by a technician. You could reach our Customer Care for repair option by looking up the number to call for your country in this link: https://pcsupport.lenovo.com/us/en/supportphonelist . Or you could also try to visit the nearest Service Provider by looking them up and their details in this link: https://support.lenovo.com/us/en/solutions/ht118678 , simply filter the list by the country or city
