my aging laptop has stopped producing a video signal; even on POST,
the screen remains blank, and an external monitor plugged into the VGA
port also gives nothing -- though the monitor power light glows green,
suggesting the monitor sees that it's connected to something.
as far as i can tell this problem started when i had the laptop up &
running unattended; the screen was blank, the fan was running like a
jet engine, and i ssh'ed in to shutdown remotely. the shutdown failed
but sshd was stopped, and i did a hard reset; now when i turn it on,
it seems like GRUB is probably loading, but that boot is maybe
interrupted by a filesystem error or something, because the network
never comes up.
anyway i'm wondering if there's a way to get data out of the machine
to help with diagnosing the problem, even in the absence of a video
cable. I've heard you can do this with a "serial console" -- can
anyone tell me more? there's a serial port on the back of the
machine, but i've never used it & don't really know how to begin with
it.
appreciate any help y'all can give! best,
matt
