Cannot resume after suspend - black screen, turns on and off

view story

http://askubuntu.com – When trying to resume from suspend on my hp envy 14t-1000 the screen stays black, and the power light/keyboard backlight/other lights flash on and off. It seems as if the entire system is turning on and off, and I have to pull the battery to restart. Any insight would be much appreciated. I'm not sure what extra information would be useful, but ask me if there is something else I can provide. (HowTos)
