Lenovo z565, Windows 7 will not start, black screen

2016-03-11, 11:21 AM

When I start-up the indicator lights go on, the fan comes on and the optical drive makes it's usual noise, then everything stops except the "sound is muted" indicator stays lit. I don't get the Lenovo screen at all.

I tried the unplug, remove battery and hold down power button for 30 seconds to reset bios and it did not help.

I also tried removing the optical drive, harddrive, wireless card, and made sure the memory wasn't loose. Same results as above when I start-up.

Any help would be appreciated. Thank you.

Solved! See the solution

Hi bcubed ,

 

 

Welcome to the Community Forums.

 

To verify if the machine is still posting ( power on self test) , would the caps and numlock led still go on /off when button is pressed? How was it when you connect to an external monitor. 

 

With the ac adapter connected , will the battery LED shows that it is still charging?

 

If you can try to check these things , we wouldbe able to isolate whether the graphic chip is the one affected.

If you place a pen light onscreen , would there be any faint image ?

 

Update us how it goes.

 

 

Regards

Thank you for the response.

The caps lock and num lock lights don't come on when the buttons are pushed.

The movie camera shaped light, fan light, and battery lights will come on when touched and stay off otherwise. The sound light stays lit on its own.

There was nothing on an external monitor when I connected it, and I don't see any faint image on the screen.

Hi bcubed

 

With all this symptoms I am guessing you already know the point of failure here.

Best that you have it further tested for both systemboard /graphic chips /cpu functionality.

 

You may call in Lenovo tech for service else consult your local service center.

Hoping for the best. 

 

Regards

I am having the same issue: Black screen on start up with sound muted indicator light on.  The only difference is I am using Windows 10. 

Did you ever find a solution?

 

Thank you.
