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?
Is this a good question?
