I'm on a roll lately!
Got an A1212 MacBook Pro, which won't do anything except flash the sleep indicator about once per second, like it's trying to power on, but something stops it. Could a faulty DC-In/MagSafe board cause this? I don't want to replace the logic board unless I have to.
Also got another A1052, so now the first one has a whole keyboard (still has a stupidly dim backlight, though), a SuperDrive, and a better trackpad clicker (the original was a bit mushy and didn't really click too well). I tried swapping the sound board and cable from the new arrival, but I still don't have sound. Could the logic board be at fault here? The other one doesn't power on, so I may try repairing the other unit rather than swap boards around.
One definite improvement, though, is a relatively sound battery. It actually charges more or less like normal, and lasts about 1.5 hours (not bad for a 14 year old battery!). It only has 47 cycles and 91% of stock capacity according to coconutBattery, so it must not have been used much; my 2012 MacBook Pro is only about a year and a half old (bought new in September 2016), and I've already logged well over 250 cycles on its battery.
I've got to sell something to make up for this spree! Maybe the other A1052, if I can get it to boot (no power)....
