laptop won't post - battery light flashes codes
My laptop will not boot up. When I hold the power button down for 30 seconds, it appears to be flashing a code. I am including a video clip of this behavior. Can you tell me what the flash codes mean?
Thanks.

Replace the mainboard.

2-4 is a memory error on most systems.

Ok. So I re-seated the memory module, but got the same results - 2-4. Then I replaced the memory module with a new one. The problem remains the same. Still got the 2-4 code. I also tried attempting to boot with no memory installed at all. I expected to get a 2-3 code this time, but alas I still got the 2-4. I'm not sure what to try next.

Thanks.

@ejn63 Yep. A new mainboard did the trick. Thanks for your insight.
