I bought Pi2530 few years ago - to be completely honest - I am really satisfied with this model but since several months I have had huge problem with a plug (charger - laptop), the charger starts to charge not until i push the plug down - then it starts to charge - but I can not use my laptop by one hand and second hand pushing the plug. I took my laptop to repair and they where not able to fix it, i took to other and he fixed it for several weeks and it happens again and again. So there is 100% sure that there is something wrong inside because the charger works correctly. There is no guarantee anymore - so it must be something wrong with a motherboard.
What would you do if you were me ? What should I do with this problem ? How much is worth this (used) model ?
