Acer Aspire 5920G DIED but Alive after a week!

Over the last few days I've read countless posts abt the same problem as I've been having with my Acer Aspire 5920G. It all started a week ago. I had shut down my laptop the night b4 and in the morning as usual I pressed the power button to start it up, it started up, completed POST and then powered on with a blank/switched off LCD screen and I could hear it going all the way up to the Vista log-on screen...... all this time with a blank screen that had no power. I kept it for a few minutes and then switched it off.

When i tried to restart,........the laptop powers on, the Bluetooth light comes on and the Hard drive led flickers a couple of times and then it'll just sit there unable to load the BIOS! Naturally I thought something was wrong with the BIOS for it to not start or complete POST. But I had absolutely no idea where the BIOS battery was located, so I couldn't do very much abt it (now I've some idea where it is, after a week of tinkering with the motherboard. )

But just to be on the safe side, over the last week I checked the RAM (which was OK), took out and reseated my GPU board (seemed OK, the GPU could have been the culprit coz of the blank screen), removed the Heat Sink (which was covering the CPU and which also acted as a Heat Sink for the GPU) and checked the CPU. The thermal paste that was covering the CPU had melted all around it, so I replaced it with new thermal paste after I cleaned it. Then I disconnected and reconnected the Heat Sink Fan and put it all back together. It didn't restart! The same symptoms as b4 appeared again. But this time after a few secs, it went into an infinite loop of powering on and restarting every 5 or so seconds.

So I thought, I'll give it one last go b4 chucking it for a new laptop! Since the first symptom of the whole problem when this all started was a LCD screen that wasn't working...... I removed all the coverings of the screen and detached and reconnected the two LCD inverter cables connected to the inverter boards thats located just below the screen and then after removing the back covering of the LCD screen, I detached and reconnected the LCD cable just behind the screen. The attachment of this cable is very fragile and flimsy. I've a feeling that this is what caused all the problems. It did seem loose!

I put it all together and pressed the power button and Voila! everything started up, taking me to Vista's log-on screen. PROBLEM SOLVED! Right now, i'm writing this post with my resurrected Acer 5920G!!!

I just want to say that this is a great forum and it has been of great help to me over the last few years! I hope that someone finds this post useful and eventually resurrects his/her dead Acer 5920G.

 

Welcome to the boards, DarcSource! I hope you stick around, learn some cool stuff, and begin to contribute back to the community when you're ready.
I had a bit of a scare myself with a no-LCD situation with my 6920G a while ago - the screen had power and was all-white, but no data was on it. Everything else ran fine, though. It turns out that I had partially tugged out the LCD-to-motherboard cable when cleaning my heatsink and fan. A-hem.

 

Congrats, DarcSorce, I'm happy that your 5920G is back to life Mine says "Hi" to yours
