Do a power drain, this may cause by an electrical charge in the motherboard itself,Im Not really sure how it affects the display of the computer but this method usually fix such problem like that, First, removed the battery then unplugged the AC adapter the press and hold the power button or the ON/OFF button for at least 30 seconds then connect the power supply back to your computer then turn it back on, if nothing happens, there is a possibility that the problem is with the LCD or monitor itself, maybe it will need a replacement...
Hope this will help...Your response is very much appreciated...
can you please try to power drain the laptop, removed the battery and the unplugged the charger then press and hold the power button or the on/off button for 15 seconds, obviously it will not turn on since there is no power supply connected, after 15 seconds, connect the laptop direclty to the power outlet without using the battery just for the meantime, then power on the laptop, see if theres any difference, if nothing happens, there is something wrong woth the monitor itself.
ok, press the Power button on the Laptop once, and if nothing happens, press the power button again but this time hold it down until it goes off... then remove the battery for 2 minutes, after that put the battery back and press the power button, it should power on and the monitor will show. (Do not plug into power source during all the above process).
Turn off notebook. Remove the battery. Press Power button. Notebook should start working. Wait for 15 secs. If the screen still blank press Power button and hold it for approx. 4 seconds until notebook is powered off. Then press power button again. Bingo, problem should be solved.
Hello, The first thing to try is to hook up an external monitor to the laptop. If the external monitor works then it is either the LCD screen or the backlight for the LCD. If not then it is probably the video card inside the laptop. Also check the "function" (Fn) key combinations on the keyboard, you might have shut the screen off with the Fn keys accidentally. Hope this helps.
