ASUS S56C black screen after disbled "Launch PXE OpROM"

Hi everyone,

So my friend's ASUS S56C was unable to start the windows and keep showing reboot and select proper boot device. At that time there still had a post screen and could enter the bios menu.

But after he changed the "Launch PXE OpROM" from enabled to disabled, after pressing on the power button, the power light turns on but there is nothing on the screen. No post screen, no asus logo, nothing. Even pressing F2 or delete continuously there is nothing appeared.

Any help will be appreciated!

 

Either OS or HDD was probably bad.
But here's hardware reset from ASUS.

Thanks for the reply.
But even the OS or HDD are having problems, I can at least see the asus logo on start up and enter the bios menu, right?

 

Right, but for some unknown reason when you disabled the LAN OpROM it disabled the whole thing completely.
But try the reset first to see if the system can post again or not.
Is the unit under warranty still? If not, then perhaps you can try disconnecting the HDD from the system to see if that would resolve the symptom.

 

Do you mean the reset button on the bottom of the laptop? Will it also reset the HDD? (this is a silly question but i just want to make sure)

 

No it should not.
Think of it as a reset button on your desktop PC.

 

Sorry I don't really get what you mean the reset. Does that mean reboot?

 

Yes, reboot, which will not destroy any data on your HDD.

 

Hi, Did you resolve this issue?
I have the exact same problem.

Thanks

 

Try taking out the any hard drives and see if it will boot.

 

Disabling PXE ROM - which is just a network boot option - should not cause this, but for future reference for others, you do not need to disable this. It can be moved in the boot priority, which is preferable.

If there is no splash screen at boot and no BIOS access, you can try removing the CMOS battery. If you're under warranty, don't risk it; send it to Asus.

 

Hi everyone,

Today, I had exactly the same problem : I changed the pxe oprom option in bios and my asus computer didn't restart. The screen remains blank, the power led is on.
Hitting DEL key didn't change nothing. I'm not able to enter in the bios.
After removing some screws, I reset CMOS battery. But it didn't change anything, always the blank screen. I'm sad, I haven't any ideas left. I read a lot of google results, without success.

Did you fix your problem ? How ? Thanks for your help.

 

BIOS is very likely to be corrupted due to BIOS modification.
You would need a BIOS programming device to restore it, or contact ASUS directly for repair services.

 

Thanks for your answer.

The warranty has expired a month ago :-(
Yesterday, I wrote to support asus. I'm waiting their response.

I'm gonna search the tool. To help, do you have any example or tutorial ? Thank you.

 

Balist, I'm in the same situation, the warranty expired and every recipe I found on google wasn't succesful.
Asus support didn't help too much, they want me to send the unit back for repair.
Did you make any progress?
Is there a way to recover the contents of the HDD?

Regards
