Dell Inspiron 14z 5423

[truemancardoza]

My Dell Inspiron 14z 5423 laptop powers on but the screen is completely blank. I had tried removing the battery and holding the power button for 30 seconds and then trying to power on but in vain. I suspect it could be something to do with the CMOS battery and since i don't have much knowledge about how to replace it . If it could be something else please share your valuable knowledge with me in getting this repaired.

Thanking you in anticipation

Regards

Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
