I have a Sony Vaio laptop, model PCG-384L. It will not power up. My wife indicated that she push some button that lock the power. Can seem to find the button that controls or locks the power button. ...


Typically that flashing light means low battery. Which makes sense, as you probably have an issue with the AC Adapter that you plug into the computer to charge it, or the DC Jack that this adapter plugs into on the laptop. Either of these things will cause your computer to not charge the battery, and if there isn't enough power it won't turn on.

My sony vaio vgn-fs285e will not switch on since this morning. Even if the AC adapter is plugged-in it still won't come on. None of the lights come on, it won't run with the battery pack or just AC power....


Hi,
To check if the problem is the power adaptor or the Vaio, just have a look at the charger itself and see if the green light on the adaptor itself is on?If yes, then more likely it is working fine. If no light, change the fuse in the plug and try again.
You can also try a static discharge on the Vaio. Please remove all external devices, unplug the adaptor and remove the battery. Put your finger on the power button and hold it for about 30 seconds. Then connect the power adaptor again and try to boot.
Regards,
Purito
