gateway laptop charging light blinking

view story

http://ubuntuforums.org – My hdd died a few days ago and until my new one arrived i have been using a fedora live cd to get on the web. basicly the gnome 3 interface stopped working and my charging light started blinking, i rebooted and as it was booting the cd the charging light was still blinking but went back to normal after it booted up. Should i be worried about my laptop? (Hardware)
