i have a hp pavilion ze 4200 laptop for my work computer. i shut the thing off last night and went to turn it on a few hours later and it wouldn’t start up. i had it plugged into the power cord, the light showing the power connections was lit on the laptop. I took some of the parts off and plugged them back in (the ram) but i can’t get the entire plastic case off. I blew some dust around in the fan and restarted. This time it booted up (I can hear and feel the fan running) and all the lights (keyboard, power) are on, but the screen is black. I tried hooking it up to my monitor for my home Dell PC, but it didnt work, although it didnt work when I hooked it up to all my other laptops, so I think my dell monitor is just too finicky to hook up to other stuff (it has like three connectors and a drive.. which i didnt bother trying to install on my broken work laptop). Last thing, when i started my broken work laptop, it had this beep code: one beep, three beeps, three beeps, and then one beep…. then no more beeping. I am thinking something is wrong with the video card, however, I can’t get the back off to find it, and even if I did, im not sure what it would look like or how to replace it…. then once i got the laptop running, (with blank screen) i couldnt shut it off! finally the battery died and it shut off and now won’t even turn on again? any ideas? i need to back up the info on it or i’ll have to do a weeks worth of work again! thanks…
