I cleared the cmos with the power cord unplugged. After plugging back in the power cord, my fans and lights etc turn on now thankfully. However, the Clr cmos indicator is still lit up on my computer and I have the A2 error code showing. So basically, I cleared cmos but its still saying I have to do it again. No display either. Any ideas?
