...(for Computer_Commando), does that mean that the POST beep code sheet on Computer Hope is wrong?
You didn't read carefully, 2-short, Parity Circuit Failure is for AMI BIOS. 1-long, 2-short is for Award BIOS. Beep code page is not perfect. Sometimes difficult to hear the 1-long between the 2-short. expecially on a notebook. Then again, BIOS beep codes are not generic, especially on customized BIOS (like Dell).
On a notebook, any kind of beeping and no video is probably the video card. Video cards on a notebook are not like the ones on a desktop. Closer to "on-board" video on a desktop, a video chip and some video memory and some "glue logic". Mine actually has a small video card, about the size of a couple memory cards.
