HP laptop display issue

My HP Pavilion dv6045nr will not show any display when booted up. Screen remains completely black, not just dim. Error code is 1 long beep, followed by two short beeps. Information I've found elsewhere indicates that may be a problem with the RAM, but I've tried replacing it and it had no effect. It has two RAM slots and I've tried swapping the cards, as well as running off one at a time. Basically i covered every possible combination of RAM placement, but got the same error every time. It was working one night with no indications of trouble, but a few hours later when I woke up it seemed that it would not "wake up." When I tried rebooting, I got the error beeps and it hasn't had a display since. I have NOT tried an external monitor yet, I would have to find someone with a desktop and don't know anyone off hand. I appreciate any help anyone can give! HP 9628nr Will boot to external monitor. Then works after reboot to laptop display. I have checked: Display Driver Nvidia 7150/M nforce 630M RAM LCD connections - motherboard Power management settings (Sleep hibernate OFF) Power adapter PheonixBIOS ver F.08 (f.32 avalable) After it appears fixed, (booting with external VGA monitor and then rebooting to laptop diplay) I power down for 2 hours, go to reboot and black laptop screen while I hear windows booting... There is a BIOS flash update but I really am not sure if it will help.

    Aha... It is the laptop lid. If, after I shutdown, I DON'T close the lid or close it but don't allow it to make the click for secure closure, it will boot properly with the laptop display working. If , after I shutdown, I close the lid and allow it to make the secure closing connection of the lid so it clicks shut, I am back to having to boot through the vga connection onto an external monitor... Keep in mind the Power settings for the lid (disabling) did not work. So I guess I can either spend $150 to get the lid closure fixed or I can place a piece (or two ) of tape over the lid clasp openings and Tah - Dah fixed and it only cost 1/10 of a penny :-)
    I wish I hadn't spent like 10 hrs dealing with this issue though when the fix was so simple... Errrggggg

    I am not sure if I can solve my own problem but here it is as you can see I placed it in comments. When I reread my problem I noticed that "someone" rewrote it for me and is slightly inaccurate now but nevertheless here is the solution to my specific issue...

If you are recving 1 long and two short beeps, it is not a memory problem.
It is not a Lid closing or lid switch problem.
If you are able to switch to and from your LCD and Monitor, you are lucky.
I have been up and down the road with several HP DV6000 series units, all have had the 1 long and 2 shot beeps.
HP is aware of this problem and has offered an extended 1 year from date of original warranty expiration. Another words 2 years from date of purchase. HP will ask for $365.00 + or - ? for this repair.
Their repair consists of a motherboard replacement.

If you go to HP's web site, you can look up your model and if in warranty, have it sent back for repair.
The problem will not get better in time but only worsen. The heat sink on the dual core units is not handling the heat transfer properly.
The board is a 2 sided wafer which has displayed failure in several places, due to the heat load and transfer design. Area of problem is directly under NVIDIA chip look for craters. Theses are solder points the size of a pins head which because of the heat and the stress of the transfer bracket above, have separated making in some cases an intermittent connection to chip.
The best thing to do is have a technician remove the board from inspection and blow out the heat sink and surrounding areas.
Apply new heat sink tape and grease where needed and re-assemble.

You must update your BIOS ver. to current.
This new version will address the Voltage and Fan Control Speeds in a better manor.
If your unit is just now giving you these errors, now is the time to act.
Just like in a A/C unit at home, a restricted air flow will make unit run longer and hotter.
Their are no filters here, once lint and dust have collected in the coils, it is just a matter of time.
Hope this helps you in your problems.
Anybody reading this note having a DV6000 series unit, should check at their web site for warranty and call back issues.

P.S. if you are a technician and feel you want to repair the board yourself, drop me an email with the model number and I will explain in more detail.

Try taking out battery and plug in power. If it works, battery is faulty. If not,
Try taking out your hard disk plug in power, if it works, hard disk is faulty. If not,
Try taking out memory card, if there's a sound, memory card faulty. If no sound, it's your motherboard that is causing the error.

Note: If machine is under warranty no need to pay for the repairs.

My HP Pavilion G6 laptop screen turns on and then goes blank (black)


When the screen turns on does it show anything or does it turn on and go to black?

If it goes to straight black it could be two things typically.
1. The LCD screen is having an issue. Connection cable / LCD screen itself.
2. The Graphics Card has gone out.
