Hi FinnishLove,
Welcome to Sony Community!
The PCG-61317L is the chassis number of the laptop, verify the model number on the lower right side at the bezel of the monitor. It should start with VGN or VPC. Once you have the correct model name, you may refer to the link below to check the availability of the AC adapter for your unit. https://sony.encompass.com/ .
