HP laptop display issue

I was using a HP DV6910US and i faced a problem when my laptop froze and i had to press thepower button to reboot.

But on reboot my laptop had all the lights on keyboard light on with no dispaly on screen/blank.

I have called the HP helpline and they told me to do these steps...
1.Disconnect all cables and usb connections of the laptop including power cord.
2.Remove the Laptop Battery.
3.Do not connect the Power cord now,Instead press and hold the power button for 25 seconds.
4.Now connect the powercord and put the laptop battery in place.
5.Now press the power button on your laptop and as the lights come on immediately press the Function/fn repeatedly.

Your problem is now solved as the screen comes on to life.
I was told that the problem is something related to the memory of the battery.

I hope my answer will help many Hp owners to solve the simple problem.
If you cannot get through you need to call the HP Toll free helpline at your place.

Hi,

You might see the presence of random lines all over the screen in some occasions in your HP Laptop.

Often, troubles are created due to this. You would see the vertical and horizontal lines.

You could solve this problem easily with the help of LCD BIST test.

For this you would have to press the function key and follow the instruction as the LCD BIST runs several colored screen.

Had the same problem. It is due to the graphics chip which cannot be reseated or removed as it is soldered directly to the mainboard. What's more is that the solder is between the bottom of the chip and the top of the motherboard so there's no way of getting to it to try and reflow etc. You could try a heat gun if you’re desperate but that would almost certainly end in the total death of it altogether as the surface mount resistors and wot-not start ice skating into another dimension!
I have just thought though that the chip resides under the heat sink it shares with the CPU. This is exactly the same as the Xbox 360 X-Clamp repair, being that the chip get's hot (which being an Nvidia - Big Fan! - it would) and then melts the solder and lifts from the PCB resulting in failure.
With the Xbox, removing the crappy inadequate X-Clamp that Microsoft fitted and bolting it straight through with decent bolts and some welly fixes it nine times out of ten. The only thing different is that with the Xbox I prefer to cool the CPU and fry the GPU for 15 minutes to reflow the joints. In this case that is not practically possible but as I said, just clamping the chip down often rectifies the fault.
Another interesting thing I have noticed about this is that the heat sink has five screws that fix it. This is interesting as it points to the fact that HP were aware of this problem from the start. Especially as the four screws that secure the CPU go straight through the PCB and into a steel bracket which gives it a good clamp but the fifth that secures the GPU screws into some naffy (definite afterthought) of a surface mounted ‘bolt pot’ with all the ‘clamp ability’ prospects that a flimsy PCB can offer! To add to that, in their wisdom HP decided that sticking some of that awful putty **** (loosely) between the two was enough to withdraw the heat thrown out by the Nvidia and transfer it to the sink!
My eight year old son could have done a better job than that!
Well I will rip it apart again later and see if I can lose the ‘bolt pot’ and screw straight through the PCB. I will also get some decent material to fill the gap and some thermal paste, I thinks. I will post the results once I have done it.
If anyone is going to attempt this then I will say that be careful if you drill the PCB as I am sure it has a middle ground plate.
Ah well, here we go again……

Just for future reference, for anyone who had a 12 month warranty, HP has extended the waranties to 24 months on certain models which are showing similar display issues:

"HP has identified a hardware issue with certain HP Pavilion dv2000/dv6000/dv9000 and Compaq Presario V3000/V6000 series notebook PCs, and has also released a new BIOS for these notebook PCs, version F.39 for dv2000/V3000, and version F.3D for dv6000/dv9000/V6000."

I own a HP DV6045nr. Was running into the same problem,however, I was not given any beep codes. The computer would boot but no display. Sometimes it would continue to reboot and the screen would occasionally work and windows would load. that was at least 10% oof the time. the other 90% is would just sit there rebooting over and over and over again.

Solutions:

If you are using the dv6045nr or similair model, the sata HDD is hot swappable meaning if you know someone who has a desktop with an available sata connector, you can connect your hdd to backup your files....

If you believe your problem is caused by overheating, HP has released a bios update specifically for an updated fan control algorithm to help reduce overheating problems....

Finally, if all else fails, like in my situation, hp is offering a recall on select models laptops due to but not limited to; no screen at boot up, no wireless on boot, no audio several other problems. This is an extended recall issued for 365 day after the original 365 day warranty expires. call hp or check out the link for more info....

Guess what everyone? We are all screwed on this one! You have an nVidia video controller in your machine, right? Yeah, well, it's dead - just like mine. nVidia has announced a major failure in MANY of their video cards, and their stock is on a downward spiral. Both Apple and HP have also announced the failures in many of their machines due to nVidia chips. HP has extended warranties on several of their machines (I'm sure more to follow as mine is NOT on the list... yet). Here are some links to get the info. You may be able to get your machine fixed for free if on the list, but I say even if they do fix it and put in the same nVidia junk, it's just going to break again in a year or two.

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!

I had the same problem the wierdest thing was that when I would get the beep noises and the screen would be black I would take the battery out and put it back in then hit the poqer button and the monitor would work fine. However cartain keys on the keyborad would not function so I connected a USB keyboard then it was ok but then Windows would not load up so i used a Live Linux CD and it would load onto that OS. But after all that even in the linux OS the computer would freeze up.

Many HP notebooks are failing for this same reason. It's a problem with the video card and the motherboard must be replaced. So many are failing that HP has extended the warranty to two years.

Excellent resources on the web that pinpoint this problem.

If you're sure it isn't a heat, dirt, moisture, or discharge problem before you woke, it could still be a defective/corrupted BIOS engaging a power save mode indefinitely. From your description, it doesn't sound like you moved it to unseat anything. No LCD TV or other to try it?

Okay, good news, bad news and really bad news. Bad news first, it doesn't sound like the RAM, if you tried replacing it, but it could be the microprocessor (1.8 GHz AMD Turion™ 64 X2 Mobile Technology TL-56). If it overheated and cracked the ceramics in the CPU, you'll have to replace it. Now for the good news. It may just be a simple BIOS reset. It may actually be trying to boot from a non-existent device (like a USB drive). Try following these instructions on the HP website (it says if you get a blinking cursor, but the instructions are still valid for reseating RAM and pulling up the BIOS).

Now, just to verify, it sounds like you've got more than one RAM card. Those are DDR2 667MHz isoDIMM memory modules and should be able to run independently. Try using only one module at a time (in slot DIMM1) and see what happens.

Now for the really bad news. I think it may be the motherboard that's failed and not the memory. If so, game over. The replacement system board (part# EZ475UA) will, more than likely, run you at least $300, if you buy used/refurbished on eBay or elsewhere, or more than $500 if you buy a new one.

Bad MB, and HP knows it and refuses to fix the problems they created. Write your state attorney generals office and tell them HP acknowledges the problem is theirs, installed an extra year warranty, but failed to tell the people with the laptops they had a fix to a problem they know will happen. When the 2 years were up, HP feels they are free and clear the problem. You should have checked for the problems.

HP use to be one of the finest PC companies out there, now they're worthless like many before them. Remember Packard Bell? What can you do? To try to fix it the most reasonable way is Ebay, they have many MBs for all laptops available there. For the DV6000, under the memory slots is the MB part number. Mine is 443774-001, you must make sure you get the right MB for your laptop, a 443775 or 776 will not work, has to be 443774-001 for my laptop, your numbers must match or you'll have problems. For this MB the price ranges from $88 to $210 for the MB, excluding shipping. Many MBs are coming from China, and they claim to be fixed MBs or repaired. Make sure you get what you paid for. Removing the MB and replacing it is not hard, directions are on the HP web site. Good luck.

I had this problem it was the mother broad it has 2 be replaced witch runs 350 buck then 4 weeks later the screen will burn out. Im glad i got the 3 year coverage

its the graphics chip hp have extened the warrenty for more info see here http://nf0g.projectnf0.com/coffeebranlaxative/2008/07/07/hp-pavilion-dv2000-3-beeps-no-video-no-post/

Well First off, I wouldent say it is because a hard drive. Thsts not going to cause the laptop to not boot(show something on the screen). I had the same exact problem *HP Pavilion ze2000* 1 long beep followd by 4 short beeps afterwords. what led to mine doing this I think coulda been moisture. after all my gf likes to keep it 60 or lower if possible. you should try to use a blow dryer. make shure you remove all cables and anything that isint high heat resistance. short blasts did the trick for me. my laptop runs like brand new besides the fact i need more ram.

you need to get some software on a disk that boots at startup and checks ur disk.youll probably find that you have bad disk sectors.which would explain the beeps which incidently do usually mean mem fault but if ur disk have bad sectors it aint gonna get to the bit where it checks ur mem.
eg you have a perfect machine,take out ur hard drive and see what happens.

It seems that I'm not the only who us facing the same problem, July 07, 2007 I bought HP laptop model of the unit is DV-6284 (which is using AMD Turion 64 X2), right after 2 months I encountered this problem ( long beep followed by 3 short ones). Now again for the second time after warranty expires the same problem happened again, 15 months to be exact. Still asking the local dealer if there is a possiblity of extending the warranty.

I have a HP Pavilion dv6045nr i have the same problem the laptop turns on but no display i get the 1 long beep and the 2 short beeps. It's a video card problem so you would need a new motherboard to fix the problem. My warrenty was expired but i talked to HP tech support and they said there is a recall for that problem. They sent me the box to ship it they will fix it and send it back for free.
