Sony vaio PCG-61211M wont turn on and the power button starts flashing on and off


This can be a sign of a discharged battery, and this may be due to a faulty adapter or the connection in the laptop.

Vaio replacement battery "plugged in. not charging"


For this kind of issue, you may try the following troubleshooting steps for confirmation:
1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure your vaio vgn-cr510e power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad
6. The motherboard could be defective & needs to be replaced.

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.

Won't turn on. Battery is plugged in and lit. n


Try removing your battery pack. Then connect the power adaptor (even without the battery) and connect is directly to the power outlet. If it powers up, then the battery pack might be defective or totally drained.

If the battery is just totally drained, simply place the battery to the laptop. Do not turn the laptop on. Plug the power adaptor to the laptop and plug it to the power source. If you see that the charging LED is blinking in your laptop, then just leave it charging up to 5 to 8 hours.

Never use a laptop on battery mode while it is plugged in to a power source. This is the number 1 reason why laptop batteries don't last longer.

It will not turn on even when plugged into mains


A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective.

Sony Vaio ac adapter submerged


If the ac adapter was plugged into the laptop at the time may be bad news. Unplug AC adapter, take out the battery and hold power button for 10 seconds. Then connect AC adapter and hit power. If that doesn't work put battery back in without ac adapter and hit power button.

If neither test works bring to repair center for diagnosis. Best case AC adapter would need replacing. Worst case Motherboard fried.

Thanks
