What we can to do when our Sony Ultrabook wont turn ON or charge and there is no light when the power is plugged in.
I will try to answer this question. Here is the steps to analyze and fix the problem.
1. Release the battery and after few seconds try to turn ON the laptop using the charger only
2. Try to use the other charger to ensure that the charger is normal
3. Open the case and release the CMOS battery, inside of the laptop.
4. Find the schematics of the motherboard of the laptop and find the 19V rel and check this
5. Find the 3V and 5V rel and check the voltage here
