so the backlight is on, but you cant see any words and it doesnt go to post or make startup soundsit just stays black or blank (like if you set the desktop background to a solid black color). when i connect it to an external monitor and do Fn+(monitor button) it doesnt work or says on the screen "unsupported mode" or the monitor just goes to sleep because it doesnt get a signal. I've also tried using a Live linux USB OS. I've powered off the system and drained all power by removing the battery and holding the power button for 60 secs or more and tried powering on to no avail and reseated the Ram cards and finally, taking the whole thing apart and back together again (reseating the cmos battery too).
the only things i havent tried are to get new ram or replace the battery or inverter.... but im not sure what else i can do...any ideas?
Compaq Presario cq56
4 gbs ram
