On occasion my screen will black out after booting up. Will see what is on the screen for a second or so then black. Thought is might be the LCD or the Inverter, but when it is black there isn't a light faded image, it is pure black. Then I did this thing that I found other people were doing. Holding the power button for 60 seconds or so while turned off (supposidly) releasing power. Now it seems to work fine.

Any suggestions on best practices to test, to make sure all is working right?

Thanks

Hello and welcome to Bleepingcomputer.

Obviously you have a laptop computer.

I have seen the solution you have tried posted on many laptop related trouble-shooting pages.

If your laptop continues to run fine since you have tried this, you should be Okay for now.

If the problem pops up again and becomes a persistent problem, this may be a sign that your laptop is suffering from a faulty connection, one that requires access to the inside of the laptop to service.

I will not post the procedure here at this moment, because it may not need to be performed if your laptops screen continues to function properly.

If you continue having problems and wish me to post some technical information on how to possibly correct the problem, please post back to this topic for that information.

Please keep us up-to-date.

Bruce.

Thanks for your reply.

Here is the Hewlett Packard web site support page for your laptop.

http://h10025.www1.hp.com/ewfrf/wc/product...p;submit=Go%20

Okay the rest of these links are related to video or video display.

Check through the list at this page for possible solutions.

I realize this is one solution you mentioned above, but I am still providing a link to it here.

Have you tried hooking up than external monitor to this laptop? If so, does the video appear normal?

Also possible related video issues.

Just tried hooking it up to my tv and it works fine on the tv screen.

The weird thing is that I am running a hard drive test as the screen is active now, dim but active. Could be the screen settings but I will have to check after running the hard drive test.

The screen did boot up all the way to my home window's screen, but it was diffenately dim on the screen, buy not on my tv.

At first I thought it could be the LCD, now not to sure. Trying to run through all the tests to make sure everything is ok. Looks like everything is checking out ok.

It could be your back-light, let me know if this problem continues to persist.

I can offer some suggestions for a possible replacement.
