I have a older (late 2007) MacBook Pro that we no longer use. It still works but the screen is getting dim and the newer machine we replaced it with is so much faster. I set it up as a sever for our home network of 4 macs and one PC. I servers our itunes, downloads torrents & the attached firewire drives works great as central files storage. Running 24/7 it draws very little power. I am just wondering if I should pull the battery? It is pretty much dead. I think it last about 20 minutes. I like having it in there, it serves as a built in UPS. But I was thinking is there and danger of overheating the battery since it is being charged 24/7. Also any comment on how robust/safe the powersupply is running 24/7. If the system dies in a year or two that OK it has already paid for itself. It merely a safety concern.
