Hi all, I've had my Sony Vaio PCG-61112U for almost a year without using it but today i tried to turn it on and it did, the problem is that there's this blank/black screen and no sounds and the only led thats turns on is the power one. I've heard that maybe it's a corrupted BIOS, but i actually don't remember updating it or anything like that.

Any ideas of what's causing this issue?

Thanks in advance,
Best regards
 
pull the battery from the unit. flip the unit over and reseat the ram. on some laptop there are few keys to force a bios reset some laptops there a jumper or a short on the bottom of the laptop system board.
also check that the backlight on the lcd did not fail if you hear the hard drive and fan move try plugging the laptop into a monitor and hit the funtion keys and ext monitor key. if there nothing posting try removing the hard drive if it a easy pull. if the drive went bad..it can hang a laptop.

checking the ram is not the solution because if it was the ram issue , it wouldnt have been able to show thw VAIO logo. So this is only a software issue.
HERE IS THE PERFECT SOLUTION:
Remove the battery and put it back in. press shift + F8 +power. You should get all the recovery and troubleshoot options.

Hi Mate,

Even I faced the same issue on my VAIO SVF15318SNW after upgrading it to Windows 8.1

I turned the internet upside down to find any relevant clues to find what caused this problem.
The suggestions answered were quite normal but no one has guaranteed it would fix the issue.

I had fixed mine on my own, please go through it to check if that helps on your model too according to win 8.1:

1. Run MSCONFIG --> Services Tab -->check "Hide all microsoft services" -->now uncheck any update related service or unwanted applications like UTORRENT, ADOBE that have a service running during the startup. However after boot if you open the app, the service will start automatically

2. Turn off the Microsoft Search Indexer service that grabs most of the processing.

3. Go to --> Startup Tab, it will say to open task manager.
Disable all of the third party softwares that start during the boot.

4. Proceed only if you require hibernation mode enabled -->Open CMD as admin -->
At the command prompt, type powercfg.exe /hibernate on, and then press Enter.

5. : Clear Temp files in the %TEMP% directory --> (Just copy-paste in start)

6. Check & analyse the C: drive disk fragmentation, should not be more than 5%

7. If you are using any antivirus program, I would suggest to switch to a cloud based since it users minimal resources of your laptop.For win 7 I would recommend Microsoft security essentials, else Panda Cloud Antivirus Protection.

8. Keep the battery consumption on balanced mode. If you have Vaio Control Center -->Open--> Turn ON the Battery- you check on the details to check out it's features, I have enabled it on my end to have a longer battery life.

9. Uninstall any unused applications they you don't require very often to free up some diskspace on C

10: Install tuneuputilities to manage basic issues.


Hope this helps!! Cheers :)

I've had a Sony E series laptop, when i turned it on then there is black screen (off black color) only power light is powered up and fan is working, no HDD light is powered up. In short, there is no POST. I can assure that there is no problem in motherboard as 2 or 3 out of 50 times system boots and POSTs successfully. Possible causes and solutions?

Thanks in advance
