""""MY SCREEN DISPLAY IS "BLACK" I CAN'T SEE NOTHING IN THE SCREEN """"

This is the images OF THE ONLY TIME I COULD SEE THE SCREEN:

 

I just googled for your problem;

https://forums.lenovo.com/t5/Lenovo...roadcom-PXE-v2-1-v9-7-8-E61-ERROR/td-p/247857

"Under Boot tab in BIOS setup, set PXE Boot to Disabled by highlighting it using

arrow keys, press Enter, use arrow key to highlight Disabled, press Enter,

then under the Save and Exit tab, highlight Save and Restart, press Enter."

Check out this thread as well, they say it could be the motherboard failure.

 

Assuming the HD is detected in BIOS (if you can check it) and you know that HD is fine you should make sure that HD os set to boot priority (not network boot as it is now).
If that doesn't help and you are sure that you've tested it with a good working HD- it may indeed be a mobo failure.

 

First of all "Thank you for your prompt response" ( I hope you understand my English )

* The BIOS detected the HD disk (BUT "NOW" I CAN'T SEE nothing IN THE SCREEN ), BECAUSE IS BLACK ! (As always it was) ...
* Only, In two times i can see the screen. In this two ocations when i can see the screen, i change the options in the BIOS. But I could not repair(boot menú) (see VIDEO or images)


Sorry for my english.

 

My wild guess is the motherboard itself.

 

Hello !

Today , After several attempts , When the computer is a long time "on" I can see the "" image """ again , I can """restart """. And enter to the bios - Operative System,etc . "My hard disk was broken", and I could make it work with another " hard disk " with Windows 7 "OK".

* I CAN ENTRY TO THE OPERATIVE SYSTEM AN I CAN "UPGRADE THE BIOS WITH THE .BAT ARCHIVE" 1.09 PHOENIX ^^

But "THE PROBLEM START WITH I TURN OFF THE NOTEBOOK FOR A LONG TIME"

* NOW I CAN SEE THE IMAGE AGAIN U.U ( ONLY SEE THE BLUE LEDS )


------I will not lower the arms-------

IT must have a solution


Sorry x my English!

 

could it be the CMOS battery playing up / died? It may be CMOS battery voltage is low.
Worth replacing it. You might wanna give it a try.

This page is right from my service manual.
I have a strong feeling it is your CMOS battery needs replacement.
