E530 Blank/Black Screen, LCD Backlight On

2014-08-28, 13:52 PM

This morning my E530 was working fine.  I rebooted for some Windows updates and when I came back, I noticed the screen was blank. 

 

I powered off and back on and same thing.

 

Even after I pull power and battery and turn it back on, there's just nothing on the screen at all.  LCD definitely on.

 

System power is fine. Red light near keyboard comes on.  At one point, I hit ctrl-alt-delete and the screen went black/off for a second then lcd backlight on again, but still no text.

 

I even put a bootable CD in the drive and I could definitely hear that getting loaded after I power on.

 

I took out the CMOS battery for a few minutes and that didn't help.  Now when I boot, I get 2 beeps.  I guess the time needs to be set? 

 

Is this almost surely a bad motherboard?  If there a videocard that can be replaced?  Could it maybe be the video cable?  Where is the LCD cable?  I can at least try to reseat that as a first step.  I took off the back panel, but didn't see anything there.

 

Anything else I can try?  Now that I'm getting the 2 beeps, I'm not sure the system is even trying to boot.  Is there any way to get it to continue past there blindly?

 

Is there a way I could connect an external monitor to it to test?  First, how do I get past the 2 beeps?  Then if I plug a monitor in, how do I get the display to go to the monitor?  If it's the m/b, I guess that wouldn't work either though.

 

If I was able to get it to boot, I suppose I'd see it on the network, even with no writing on the screen.  Before I reset the CMOS, I did check from another PC and didn't see it on the network.  Also, before the CMOS reset, I was just getting the blank screen, but it didn't seem like it was booting windows.

 

Any ideas? All help is appreciated.

"I rebooted for some Windows updates "

 

The latetest August windows updates are crap. restore from system restore or from your PC's full image backup.

I appreciate the help, but maybe I didn't make myself clear in my OP.

 

There's nothing on the screen when I turn it on.  No Lenovo logo, no text, no way to get into the BIOS, etc.  It's not a Windows OS issue.

 

Anyone else with suggestions?

Anyone have any ideas or suggestions of things to try before I junk this?

 

Not sure I want to spend $150 and a good amount of time replacing the motherboard and find out it's something else.

Surprised no one could offer any advice here.  Since it was under 3rd party extended warranty, I had to bring it to a repair shop to get an official estimate.  They did some testing on it and feel it's the motherboard.

A friend of my had exact the same problem, in his case it was the msata caching SSD which caused the problem. As this topic is quite old, I don't think this information would help you anymore, but I hope so others. 

 

His E530 was equiped with the Sandisk 16GB with FW: 10.52.01
