It is likely that the backlight went out on the screen. This model has an LED backlight and can be replaced. If you are mechanically inclined, you can purchase a new one on ebay or amazon and replace. If this is a motherboard problem, then it is likely not worth fixing. One way to tell is to see if the screen is completely black. To test, turn on the computer and go near a bright light source. if you can barely make out any image on the screen, then the LED backlight is bad. If the screen is as dark as it is when the computer is off, then it is likely the motherboard.

For further help please check Dell Inspiron 1525 Manual. Also confirm if the light on the charger stays on,when connected to the system.

My IBM T40 boots to a black screen with the "z"(light at top to right of power.


Try these steps:

1. Remove battery and unplug AC adapter
2. Press power on button for 30 seconds or so (one min is also too)
3. Attach battery and plug into wall
4. Power "ON" as normal

If you are still getting the "Z" and a black screen then I would have the video card or hard drive looked at and replaced. Start with the video card and then look at the hard drive

"z" light comes on, then battery charge indicator -Doesn't start!


Hi,
If there no indicator of power on the laptop , There could be two problems either the AC adapater is bad or the motherboard connector pin or board is faulty.
If you see power light activity , but the screen is blank. try connecting an external monitor to the laptop. Press the Fn+ F8 key to toggle the screen to the external display. If you see the display on the external screen then the LCD is bad . Otherwise its your video card.

How to use the S view port - switch monitor


Press the blue FN button and one of the F1-F12 buttons. It should show two screens. Also make sure you have changed the display settings in windows. Under the advanced Tab check the box that says "extend my desktop to this screen" after selecting the 2nd screen in the window above it.
