I've got an early 2011 Macbook Pro that I bought last year. Everything's been running great since day one. However some issues over the weekend. Last week I noticed issues with my battery and the "Service Battery" was showing up if I clicked at the top where my battery was charging and shows the percentage level. I didn't think anymore of it as the battery was still holding a small charge and figure I'd get it checked out in a couple weeks. This weekend even more issues. I have an Intel SSD drive as my boot and main drive, then a 750 GB drive in the optical drive spot. It's been like this for almost a year now. Yesterday I went to boot it up and noticed the white light on the front flash roughly five times. Then it started up and stayed on the Apple screen for a very long time. So I turned it off and started it up again. Same result, except this time it booted from my 750 GB drive (still had old copy of Lion on it from where I had it before buying and installing the SSD) instead of the main SSD. I went into the Recovery mode and the SSD is not even showing up now. All I see is the 750 GB drive. Also when booted up now from the 750 GB drive, the battery shows 0% and stays there. Plus the light on the battery charger cable is green rather than orange as if it was charging the battery. So now my question is, why won't why MacBook Pro boot from the SSD? Is it because of a bad battery? I hit the "Option" button when the laptop starts and there is no option to boot from the SSD. So I don't know if I have a SSD issue as well and the battery. Or if the battery being bad it would cause the SSD not to boot properly. I wouldn't think so, but I'm not an expert on the SSD. I did take the bottom panel off, removed the SSD and re-seated the drive and cable to see if that would help. Nothing. Thanks for any help for anyone.
