Won't boot up with AC or Battery power
The computer would not wake up from sleep mode. I had used it then closed the cover and when I opened it back up it did not respond. With the case opened up I can see the fans start when I press the start button and the CD and HDD spin up then everything stops eve if I hold the start button.
In the last month or so I have noticed some peculiar things; one time the screen stayed black at bootup after checking a few things online I did the Opt/Com/R/P reset, until today that seemed to fix things. Another thing was the keyboard would lockup (not respond to key strokes), this symptom only happened when I was using Photshop (CS6).
Fearing a possible HDD failure I have backed up my data on a portable drive as recently as yesterday but it's not bootable so I can't boot up from that device.
Unfortunately I don't have a boot disk either.
Is there any info available concerning voltage test points?

What does the battery test tell you on the battery? What happens when you take the battery out and just have the power adapter plugged in, are you able to boot up? What color is the Mag light plug show and is it dim or well lit?
