Question about Sony VAIO PCG-K23 Notebook

1 Answer

Screen light off

Oh dear. I know we're talking about a black screen here so I'll try to be as detailed as possible. Here is the problem: Computer turns on. Vaio display lights up like it's supposed to. Then a screen with a blinking "_" shows up, like it's going to write a script, and then the light of the screen goes off. After this, you can see my computer thinking and booting through the little orange CPU light. Then the three caps, number lock, scroll lock buttons flash. Then my computer boots up with the screen light still off. Pretty Windows sound...and we're at this darkened desktop as if it's on minimal battery settings. What I've tried: Funny thing about this is you can still see all the activity on the screen if you look at the screen at the right angle. I can see spy sweeper...and my AVG updates. If I hit Windows on the keyboard I can bring up the menu. The light is just off, almost as if my battery has been unplugged...only my battery is in. I have tried adjusting my power management options, I have tried increasing the brightness, I have tried waiting patiently. I have tried restarting in safe mode and other modes. I have tried to see if there were any other refresh rate options...but i'm locked into 60 hz. What sometimes fixes it: One thing I've noticed that may trigger this behavior is not having my computer plugged in when I turn on my computer. If I turn on my computer without having it initially plugged in, even if I plug my computer in later after booting, the screen will still be dark. Once in a while, my screen will light up again if I switch the outlet that I'm using to plug my computer in. What outlet I switch it to seems to be arbitrary. It's just the act of switching outlets that seems to do the trick. Last week after I had gotten the light to work, I would work a little while on my word processor and the light would go out for about a minute, then turn back on. I'm really worried this is a hardware problem. I've done everything I can with the settings. I would appreciate any help I can get.

Screen went black

is there any light emitting from the device at all? (turn off light and see if the screen is showing light)

if it is, check your brightness settings on the device

if there is no light it is possible that the backlight burnt out, or that there are settings that need to be adjusted on the device. It is also possible that you downloaded an app that doesnt work properly with your device.

if none of this seems to be whats wrong, more information would be nice:

1) what model of tablet are you using?
2) what version of android OS?
3) what app were you trying to install?

From there you'll be able to get more help if needed.
