Hello all. This is my first post here and I'll admit I'm mainly a PC guy but have always had an odd soft spot in my heart for Mac's/Apple products. I recently brought a shiny new iPad Mini into our home as a Christmas gift for my wife and she absolutely loves it (I'm also pleased to report my PC's around the house haven't ganged up on it yet hah). I have a few older machines (G3's and G4's) in the closet that I pull out every now and again to get nostalgic with but they really aren't useful for anything modern I want to do with them. I also have a Mac Mini coming in from eBay soon that I plan to upgrade and use as a media center but I'm getting off topic. Anywho, without spending a whole thread getting into why I am interested in Mac's, I'll get down to it. I have found a locally used (but in good condition) Macbook 7.1. It's got a Core 2 Duo in it at 2.4ghz with 2gb of RAM, a 250gb HD, and I believe the GeForce 320M video card. I scored this little beauty for $75 but there's one issue: no sound. They tell me they can start it in Safe Mode and it works fine (but again, no sound). However, when they try to start it in "normal" mode, it won't fully boot: you turn it on, log in, and it hangs on the login screen. Also of note is they tell me that there isn't a chime when you first turn on the computer, either. Possible the headphone jack is still thinking there's headphones plugged in? Searching google hasn't yielded me many useful results. So far when I get my hands on it tomorrow I'm going to reset the PRAM, NVRAM, as well as the SMC in hopes this fixes it. If that doesn't do it, what should my next steps be? I'm debating upgrading to a newer OS (Mavericks or later, possibly) but don't know if I want to put too much into it if I can't get some sound out of the old girl. So any thoughts to welcome a new Mac member to the forums? I hope this isn't too big of an issue as the lack of threads/info I found around online involving this specific set of problems was scare. Thanks in advance, guys and gals.
