Question about Acer Aspire 5100 Notebook

Black screen on Acer 5100, but will work with external monitor

My laptop is a little over a year old. About three months ago I came home and the screen was black. Anytime I turn the computer on the screen will light up very dimly and then go back to black. I have it hooked up to one of my old desktop monitors and the other parts of the laptop are functioning fine except for the screen. Before this "blackout" I had occasion problems where the screen would have light colored vertical lines going all the way across the screen. I would just reboot and the screen would be fine for a few months. I do notice that even with the screen black it will still do that occasionally because it shows up on my external monitor. Is there anyone out there that may have any insight or advice as to what may be happening?

It sounds like the control board or cable for the LCD may be damaged. If you're still under warranty, you'll need to send it back to Acer to be repaired.

I have a acer 4740g laptop.I ve got display problem.It shows several lines and i cnt work on it.Recently it got little pressed on its display.Can any1 help me?


Hello shreejan_man

First thing to do is to test the screen. Also you have not mentioned if there is any cracks or damages.

Plug the laptop to an external monitor (any type will do). If the display on the external monitor is OK then it means the laptop screen is damaged.

If the display on the external screen is the same as the laptop then the problem is internal with the graphic chip or the video contacts.

this laptop is not that old since acer released this model last year. Check you warranty status on it. Some acer laptops come with two year warranty. Check the laptop carefully, if there is no sign of physical damage, (cracks, chips ...) then take it back as a warranty issue.

Good luck

My acer laptop screen is black


Borrow an external monitor from someone. Plug it into your Acer. Power on both. Your laptop should automatically detect the external monitor.

Acer Aspire 9810 Screen Problem


Hi No otto,
On the bottom row of keys, you will see one marked Fn, in a different color. Hodl that and look at your top row of keys. Should be one with a laptop screen, and a monitor. The little graphics will be the same color as the Fn key. Tap that once, wait, see if the screen comes to life. Usually that key is set to choose "Just laptop screen, just external monitor, or both", with each tap.
Good luck,
