SOURCE: Compaq Presario laptop C300 - issues (orange light)

Sometimes when a PC gets stuck in hibernation mode, the only way to reset it is to remove the CMOS battery for 10 minutes and replacing it. It resembles a large watch battery and is usually located near the center of the motherboard.

Hello,

Since the laptop works fine with an attached monitor, it means the problem is the inverter.

The problem with your laptop screen is that the inverter is malfunctioning, that is why you have those three equal horizontal sections.

Change the inverter of your laptop screen and you will see that the screen will be stable back.

Take care.

Hp presario f600 boots and runs but screen wont cut on

Well if you are sure the computer is running, then you could have a bad inverter, take a flashlight and shine it on the screen, if you see the icons and computer booting, then you have a bad inverter, go on amazon and order another LCD. also if you have a desk top monitor, connect the monitor to your laptop, then boot up your laptop, hold down the "FN" (function) button and press "F4", you should see everything on your desktop monitor. Good luck.

Black screen with flashing horizontal lines

You may have a bad backlight screen power supply board and that is usually mounted in the bottom part of the screen right behind the front bezel. This supply's high voltage to the backlight tube that lights the screen. This is kind of like a small florescent tube that uses high voltage to fire the backlight and is a common failure point in laptop screens. Easy to fix, just pop the front bezel off and the module will be in the center bottom section of the screen. Do a YouTube search on how to disassemble your model's screen and the parts can be found on Ebay. Good luck.

View screen only 1/4 readable

Connect to an external monitor, see if the display is normal there. If it is, then reseat the LCD cable connection on the motherboard. If LCD is still messed up, then replace the LCD.

If the problem is the same on external monitor, then replace the motherboard.
