Hello,
I am having a problem. My laptop LCD screen broke and I don't have the money to replace it, but what I do have is a extra Monitor. I want to hook my laptop up to this monitor but I can't see what I am doing with the screen broken. I wanted to know if there was any buttons I could press to make it show up on the external monitor. I have a HP Pavilion dv9000. Please Help.

When you hook up a laptop to an external monitor you have to press a few buttons in order to change the output from the internal monitor screen to an external monitor.

To do this :
  • start up your laptop, and press and hold the function key which is the letters "fn" inside a box.
  • Press and hold this with the corresponding F# key that has the monitor symbol, which may look like this " lOl " or some variation of that.


This happened to my brother's old laptop, he broke the screen and I just hooked it up to an external monitor and it worked fine. It may not kick on right away with mine, what mine does is it starts up on the external screen then dispears when you log onto the computer, so what I do is I log on, I just type my password because once the log on screen kicks on it automatically puts the cursor in the password box, so I put in my password and I press the function key; "fn" and I press and hold it with F4 which is my external monitor key, then after a few seconds my external monitor kicks back on. Hope this helps!!

IF FN + F4 DONT WORK OR YOU CANT SEE YOUR SCREEN TO SELECT THE RIGHT OPTION DO THE FOLLOWING


1. Hold down the windows button and press 'p'.

That makes four options pop up side by side.

2. You would want to tap the right arrow key three times to get to the 'projector' option and press enter.

You should now be on both the laptop screen and TV

I had the same problem hooking my dell notebook up to my 42 inch plasma. My notebook screen was broken and every time I plugged the cable into the laptop, it would make a noise but the tv was still black. It worked before, but I couldn't get it to work again. All it took was pressing fn + f8. Hope this helps.

My son's laptop monitor stayed black and the computer would try to boot and then shut off and restart and this was while it was plugged in. So, I took the battery out, plugged it in and the monitor works perfectly. I put the battery back in, plugged it in to the electric and the same problem, black screen. Took the battery back out, plugged in, monitor working. the battery is interfering, I suspect it needs replaced.

YES FN +F4 WILL WORK (NOT fUNCTION + f5) IN SAFE MODE HELP - SAFE MODE WILL ALWAYS WORK) DON'T WASTE YOUR TIME WITH INDIA SUPPORT THEY WILL TELL YOU TO REPLACE THE SCREEN. I had the same problem.

Answer 11 / 13

fn+f8
Answer 12 / 13

hit the fn key and f4 or f5 and mine works fine. sometimes you may have to reboot- if it has a hdmi hookup it detects the hookup most of the time. when using the dvi or vga I have to unhook and reboot until I can get into the control panel and change the display. you can also usually boot up in safe mode.

good luck

I had same problem.I had a bit of a view on my screen and what I did is connect the lead to my tv or monitor turn the computer on and just guess where my icon was to log in. I logged in on the main screen what view
I had I right clicked on the d pad and I could see some options click on nvidia display and you get more options then click on the one that says screen options then you should see laptop display and what eva your lead is connected to mine is a samsung. Click on that and it should display an icon saying this setting will save in 15 seconds then every time you turn your laptop on it will come on the monitor.

sounds like your inverter board,its a cheap and easy fix.if the screen is black but you can see that the is pictures threw the darkness,as if the light is off.than more than likely its the inverter.
