I bought a Raspberry Pi 2 a couple of years ago and it stopped working at some point so I left it in a drawer. The problem with it was that the spring in the microsd holder had broken and when inserting a card it remained loose so I was unable to boot.
Today I came across the unit and just out of iinterest connected a power supply, no card, and the LEDs started blinking. After insertng a card the initial colourful boot screen came up but seemed to go into a boot loop after the raspberry appears. The behaviour seems to depend on how far the card is inserted.
Any suggestions as to what to do with the card?
