I disagree, I followed other suggestion,take battery out,hold start button for ~60 secs ,put battery back in and turn it on as usual. IT WORKED FOR ME !!

Thats actually a poor answer because "go to a service technician" is the obvious answer BEFORE people get online but people look online for alternative solutions that could avoid doing that. If you don't know the solution just don't respond. Or you could have left it at "Its a hardware problem" and explained why you are so certain of that, then let the asker decide if they are qualified enough to pull the thing apart and gut it DIY style. I guess everybody else liked this curt response but I didn't.

I agree with you. If people say its a hardware problem why don't they elaborate if they know so much.

same here, i tried nanor's solution, and it seems to be working for everyone but me :/
the power light is on, and when i connect the cord, the charging light goes on too; the quickplay lights and all that are on, and it's making the noise as if it was normal, but the screen is BLACK, no sign, nothing. didnt even show the windows logo or anything, just black .
i dont know what to do, i have s many realllyy important pictures here, i can't lose these pics and other files. i got this laptop only 3 months ago.
SOMEONE HELP ME, PLEASE!!!

Okay I have a similar problem. I am using my laptop through an external monitor. At first, my screen would come on and off depending where I would put pressure on the keyboard. Now, I can't see my screen from the startup. But in certain lighting i can see the screen, if i put a flashlight to the screen I can see it. Is it the inverter? I have tried the 30/60 second method and it DOESN'T work for me. Please help if possible.

Thank You

I tried the suggestion Nanor gave the first time and didn't do it correctly. The second time I followed his instructions to the tee and it worked. I was just tickled pink. I unplugged the power, held the power button for 60 seconds then reattached the power, and attempted to boot then shut it down, then put the battery back in and it booted right up. Thank You for your help I wasn't looking forward to putting it in the shop. I believe the shut down step was the step I missed the first time.

Thank you soooo much for your advice. I had the same "Black Screen" problem. Last night I was using my laptop just as usual.... no problems whatsoever. I finished my project, closed the lid of the laptop (didn't shut down or put it to "sleep") and went to bed at 11:30pm. I woke up at 5:00am to continue my project, opened the lid of the laptop and my screen was black - and stayed that way. It was kind of like "the lights are OFF but someone WAS home". All the sound was working, I could hear everything running like usual yet no screen at all. Yes, PANIC!! I did a Google search and I stumbled upon this site and read all of the posts. Finding this string of posts was a true blessing! I tried the fix suggested (unplugged the power, took the battery out, held the power button for 60 seconds - said a little prayer and crossed my fingers - then plugged back in the power cord and tried to boot it up like normal. POOF!! It worked just as usual. I had the black and white screen saying that my laptop shut down improperly and did I want to start it up in Safe mode or Normally (because I did try to turn it off - using a hard shut down - to try to see if that would work, but it didn't). I said to start Normally.... lo and behold all began to work like a charm!

Thank you sooooo much for posting this fix for all of us to try. I was dreading taking it in someplace and getting charged a ton for a simple little fix like this.

My laptop is a HP Pavilion dv9720us Notebook PC. It has NVIDIA GeForce Go 7150M graphics. I bought it about a year ago (perhaps even just over a year ago) and am probably out of warrenty. (double yikes!)

Again. Thanks for posting this fix. I would suggest to anyone to at least give it a try if you are having the same problem.

Take care-
Shannon

I'm glad this fix has worked for so many people. I've had to use this fix again since posting.

Just to be clear this is not a fix for screen problems, this is a fix for a problem that prevents the laptop from booting at all. The laptop would not even attempt a POST and so would not even get as far as trying to output anything to the display.

I'm no expert but just wanted to share a fix that worked for me. For me it was a problem with the laptop not coming out of hibernation properly and completely freezing, the only option was to power off. On reboot nothing would happen, the screen would not even be initialised so it is nothing to do with the screen.

I can only theorise what the problem may be. As the solution is to remove the power lead, remove the battery and hold down the power button it would seem to be an issue with the laptop retaining some residual charge which is preventing the laptop from booting. I've heard of other poeple who have managed to fix this by simply letting the battery run out and then leave it overnight, this will again dissipate any residual charge but is just a much slower way of doing it. Holding the power button down with no power sources attached will dissipate this charge and allow the laptop to boot when a power source is reattached.

Unfortunately if the laptop boots and the screen is blank then it is a different issue, if the image on the screen is faint it is most likely a problem with the backlight and in these instances this fix will not work. Before posting this I thought this was an isolated incident but there have been so many replies it would appear to be a more common issue than I thought and works on many different models, not just the DV6599 that I've tried it on.

Thanks for all the postitive comments and I'm glad this has saved so many people a lot of money in unecessary repairs!

I seem to be having a similar problem with my dv6000, I was working on it the other day when it made a strange noise swiftly followed by 'The Blue Screen' then shut itself down, I've not been able to get it on since then, if I hold down the power button all the lights come on and it seems to be busy doing something but the screen stays totally blank - do you think there's any hope of saving it, I've only had it for just over a year/just long enough for the warranty to have run out!

Okay, guys, I've tried EVERYTHING on this thread. Did the battery trick a million times, checked to make sure RAM was seated properly, tried a different AC adaptor, left battery out overnight and unplugged, tried external monitor, unplugged the actual backup battery to clear CMOS...I'm out of ideas!!! It was giving me this problem for a few months and I finally found a Windows hotfix that cured it, but then two days later it started doing it again and now it's not coming on even after probably 50 tries.
WHAT COULD IT BE??????
Thanks!

Thanks Nanor! This fix also works on Acer laptops, I have Aspire M3200. In addition to this issue my screen also had a small crack, after my little niece "accidentally" dropped it. I had to purchase brand new laptop screen and I could not believe how much better the computers look. Thank you guys!

I unplugged my HP 2133, took out the battery, plugged the laptop back in and turned it on and it started correctly. I then put the battery back in and unplugged the power. That worked fine. Thanks to the contributor who suggested it. The n F6 suggestion did not, however, work for me.
