MacBook shows no signs of life

Hello everyone,

I received a laptop from eBay yesterday, but unfortunately, it doesn't show any functionality at all. Specifically, neither with battery power nor with the power adapter (even with the battery unplugged) anything happens. The power adapter also doesn't seem to be recognized at all - there is no LED light on the power adapter. Could the charging port be damaged, causing the device to be completely drained? Or is it more likely a motherboard defect?

Another thing I considered: The device currently doesn't have a hard drive, but I want to install an SSD... Could that change anything? I wouldn't think so because at least the charging light on the power adapter should come on, right?

RAM is installed, the battery is in, and otherwise, the device looks good from the inside at first glance, although I haven't removed the motherboard yet... What could I check, or how can I proceed to find the problem, preferably with as little capital as possible?
