Hi, to isolate the issue perform the following.
Step 1: Hard Reset
To perform a hard reset, please follow the steps listed below:
1. Unplug the AC adapter from the notebook PC and remove from any port replicator or docking station.
2. Remove the battery from the notebook battery compartment.
3. Press and hold down the power button for about 20 seconds.
4. Insert the battery and plug the AC adapter back into the notebook PC.
5. Press the power button to turn the notebook PC back on.
Step 2 :External Monitor
1. Turn off the notebook.
2. Connect the monitor cable from the external monitor to the monitor port on the rear of the computer.
3. Connect the monitor to a power source and turn it on.
4. Press the Power button to turn on the computer.
At this time, please follow the instructions mentioned below for switching the display to the external monitor:
The notebook's video card supports three modes. Built-in screen only; external video only; and both on simultaneously (mirrored). If you're not seeing the image on the desired device(s), the notebook's video card is probably in another mode. Press FN + F4 to cycle through the display options: Notebook display, External monitor, both.
If you press FN + F4 once, the external monitor will display & there will be no Notebook LCD display.
If you press FN + F4 twice, the external monitor will display & there will be some shading on the Notebook LCD.
If you press FN + F4 thrice, both Notebook LCD & external monitor will display.
If the issue persists on the external monitor, then this could be due to defective video card on the notebook. However, if the display on the external monitor is fine, then the issue is with the LCD display panel of the notebook.
