So there are many problems which will cause issues of the screen.
- Try Fn + F5 or something like that
- Remove battery, unplug power, hold power button for 60 seconds, turn on computer with power plug only, then shutdown, add battery and restart
3. Magnetic On/Off Switch to detect of Close/Open Lid
- Your magnet switch is fubar some how. Open up the speaker cover and see if your lid actuator switch that come in contact with the magnet on your lid cover is stuck or not (find where the magnet is in the back of the front lid cover, trace where the magnet area actually touches the base of the computer and you will find the switch)
- Workaround, start windows with lid at 30 degree angle
- You need to replace either Inverter, Blacklight, or everything. =)
Good luck and have fun!!!
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!
So, I do a google search and this is the first place I come across. Nanor, your advice is fantastic. I have no idea how you managed to figure out the hokey-pokey-dance to get this trick, but thank you for the time invested in doing so.
I tried the original: Remove battery, hold power button, plug in power cord, reboot,... still had the black screen", so I scrolled down and read a few more posts. So I redid the song and dance back up to the reinsert the power cord and turn it on, but instead of opening the lid all the way, I opened it just far enough to reach the power button, this did the trick; the screen lit up! and the boot process was clearly visual again! ..."continued to do a proper "shut down", reinsert battery, etc etc. powered up again and everything was just peachy!
1. UNPLUG THE POWER
2. REMOVE BATTERY
3. HOLD POWER BUTTON FOR 30/60 SECONDS
4. REATTACH POWER AND START THE LAPTOP
5. SHUT BACK DOWN
6. PUT IN THE BATTERY
7. THATS IT
honestly, it works like a charm
thank you so much!
love Zoey :) xx
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.
Thank you very much for your solution to the problem. It worked for my HP DV 6618cv. HP should include this in the troubleshooting section of the manual. I will never buy an HP product again, or better yet never buy any PC again, not worth the headaches. In 13 years of computer use never had a problem with a MAC.
So many thanks.. Sure you're my saviour
