When I push the power button, the computer doesn't boot up. The battery light indicates it's charged, the adapter light is on, but nothing happens. The cap lock light flashes for about 20 seconds, then goes out.

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.

Can't power up. my IBM ThinkPad T22. I have the green light that indicates that it's charged up, however when I push the power button it just makes a flash and nothing happens.


If you only get a green light, try removing the battery first. If a laptop battery has gone bad, it will prevent a laptop from booting up.

Now, if removing the battery doesn't resolve your problem, check the laptop charger to make sure that the adapter has not malfunctioned.

If your fans are spinning, then the problem is probably the one listed below.

The transformer may not be converting the voltages properly.

Try these steps first. If it comes down to the internal transformer, then you have to contact IBM.

Solution
If the notebook does not power on:

Make sure the ac adapter is correctly plugged into the notebook and into the power cord.

If everything is plugged in correctly and it still will not power on, follow these steps to complete a ‘power reset' of the notebook.
  1. Unplug the ac adapter. Keep ac adapter unplugged.
  2. Remove the battery and keep the battery unplugged.
  3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
  4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
  5. Normally power on the notebook.
  6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
  7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.
Also, depending on whether your power went down "clean" (quick and stayed off), or went down and quickly came back on and off many times. Or when it came back on "clean" (came back on quick and stayed on), or it came on then off many times, your power supply may have been damaged from the power surges Are you having any problems with any other appliances?
