I have an old Vaio laptop and I am trying to see if it works but I don't get any lights on the laptop when I try to power it up. I only have the little green light on the power supply
Это хороший вопрос?

Hi @surfalia ,
Use a voltmeter to check that there is 19.5V DC on the charger plug. A green light on the charger doesn’t necessarily mean that there is a voltage output getting to the laptop as the charger’s cord/plug could be faulty.
If possible try using another known working compatible charger and check if the laptop works.
If the charger is OK there may be a problem with the DC-In jack - supplier example only.
Use the Voltmeter to check if the voltage from the charger is getting to the motherboard.
Here’s the ifixit Sony Vaio VPCEB11FM guide which should help to gain access to the DC-In jack.
