As I didn't really see a 'dumb questions' topic, I'll just ask here:
I've dusted off my Atari Lynx yesterday and tried to boot it using the original power cable. Sadly it didn't really seem to want to boot (it did get power when I fiddled a bit with the plug part that goes into the Lynx). So I scavenged for 6 batteries, put those into the Lynx and it boots without any issues. So either the power port is dirty / worn out or the adapter (the plug part) is dying.
To verify this, my plan is to get an universal power adapter with a 3.5 mm x 1.35 mm plug (if I'm correct, that's the one the Lynx uses?). I could also look into somehow cleaning the power port (I'm not sure how to go about that though...).
Any advice or does this problem sound familiar to anyone? In the meanwhile I'm looking for my second device as well (which may still be at my parents actually), which also has it's own power adapter... I'm at least trying to get a completely working Lynx to get the McWill mod done. It feels a bit of a waste if it only works with batteries...
Thanks in advance!
