Hi @bravenius
If you know how to open up the laptop,
I would suggest you to check, if it is not integrated, take note on it and compare with the seller site description and pictures, e.g. ebay,
else if it is integrated, you need to have good soldering skills, e.g. rework station to remove the card reader and again, check the parts of the card reader mechanism manufacturer from ali express, ebay, etc
else, get a multi usb card reader, as another alternative to read your sd card.
