Question about Computers & Internet
Screen flickers may or may not go dark (blank). After shutting down and restarting I could get into the bios (F2 key ) and changed the default value for monitor screen type from auto to LCD. Screen stayed on but still had flicker. Kept feeling that it would go dark again. Changed the refresh rate from the default value of 59 hertz to 60 hertz (the only other value available on the drop down list). Screen still had flicker - no change. The laptop is about 3 years old. Used daily, never dropped, always used an auxiliary cooling fan. Any suggestions as to cause or fix? Thanks Mike
Sounds like you need to think about buying another laptop. Or replacing the LCD screen. Search ebay or amazon for screens.
Here's an instructional video on how to replace your LCD. This should cover most Apple Macbook laptop models:
Here's another one:
OR if you are having problems with installing the inverter cable inside the inverter board, here is one showing you how to remove the clutch cover (middle part of the laptop that covers the inverter board inside):
Here are others for other laptop brands:

Sounds like the switch that tells the cpu when it's open or closed is going bad. On most laptops there is a little switch that protrudes from your keyboard (usually in upper corners). Try cleaning it with isopropyl alchol(rubbing alchol) and a q-tip and see what happens. If you can't locate the switch on your model get back to me and i'll research a little deeper for you. Hope this helps

You may want to rule out a loose connection.
Move the laptop screen back and forth and see if you notice any flickering.
This does not sound like a software issue, so we can rule that out.
If you have a consistant brightness on the display, we can rule out the backlight.
Their are two connection points on the display monitor, one is just under the power button and the other is behind the LCD screen.
I was going to suggust plugging into a external monitor but can't really see any outcome in that.
It may be a inverter problem, that is located inside the LCD, just behind the HP square design. You will find a input and output.
If any of these connections have come loose, that would cause the flickering.
If the backlight is consistant in value, you can rule out the lnverter.
If the unit has been dropped, it can be any of the above.
With the 20 min. to 6 hours useage, I would go with the inverter. If after the unit cools down for a few minutes, it works again, its the inverter.
Hpoe this mess of info has helped.
