Does anyone know how to fix this problem?  
 
The power cord is working but computer screen stays black.  
 
I appreciate any advice, thanks!!

check the fuse

if so, that's not the problem.

Your screen may be done... try connecting an external monitor to your laptop and then ensuring you send the video signal to that port (often by using the Function key in combination with another on your keyboard with a monitor symbol on it) Also, cycling through your video output options might light up your screen again if you accidentally hit the keys to send the signal to the external port only at some point.  
 
If the external monitor works, I'd say your screen or connector is shot.

Lol

There are two things have worked for me but first, there may be nothing wrong with your drivers or hard drive. It may have to do with the connection between the mother board and the physical screen. I'm not a PC tech but I know enough to manage my way around hardware and this is what has worked for me:  
 
Solution 1: As stated by other users, perform a hard restart. Remove the battery and leave everything unplugged for a few seconds then only plug the laptop in (without battery). This has actually worked very well for me for many months however in recent times I had to do this multiple times before the video card would boot on start up.  
 
Solution 2: As stated above it may be connection between the mother board and physical screen. Instead of opening the laptop screen to a full 90 degrees (completely upright) I leave the screen partially closed at or less than 45 degrees and press the start button.  
 
Solution 3: (Like MacBook above said): There is a key that has "FN" on it (Usually light blue printing), and then a numbered key as in F1, F2, etc. (It may be F4) but look for a symbol in blue that shows two computer screens. If you press the FUNCTION "FN" key and the key having the monitors pictured on it, (F4?), that may fix your screen. (this setting on laptops is for running external monitor).  
 
I hope this helps ->: Let me know what happens.

not sure if your having the same issue as i did but sounds like it ......take out battery and unplug power cord hold down the power button for 30- seconds to a full minute .....tec at acer told me it was from static electricity in the screen and it worked.... hope this helps

we shall try soon to see what works!!

Were you trying to upgrade it to Win 10 or did it happen suddenly?  
If you were trying to upgrade it to Win 10 then just hit the increase brightness key and see if it this works. With win10 upgrade this has been the issue with many.
