I have found two old macbooks in the house me and my family live in. They are a MacBookair 2011 and a MacBook pro from 2008. I don't want to throw them away cause they are usable. I daily drive another 2013 MacBook air, very small and great for what I do with it, Wich I'm still looking to put Linux on it. For the 2011 MacBookair I put MX in it and I'm pretty good with it(but I want to use it as backup for the 2013), but with the 2008 MacBook pro there Is a problem: there is no battery to be found and it works only connected to power. Since here there are kinda frequent power outages for a minute or so I still can't use it for something that requires it running all the time. Do you have any suggestions on what to do with it or any distro? (For the 2013, 2011and 2008)

Sorry for the trouble

Have a great day (and I hope this is relevant to the community)
