ok i have been experiencing the same problems as all of u guys. the reason why the screen goes black while the lights are still on and fan still on etc. It simply means the graphics card is overheating on the Board, the simple solution to this is to replace the thermal pad on the heatsink that covers the graphics card as it may have worn out or you can just clean out the heatsinks and fan etc.

i have a hp dv4 2145dx and it does the same thing to me. this is not fun. i'll leave the laptop on, on a laptop cooler station and i'll go to move the mouse and it will not respond. i've already had to have the hard drive replaced. HP are you giving me cheap hardware for a high price because i don't know anything about computers?

also why should i have to pay for their mistakes? if my graphics card is heating up too much (when i don't use my laptop for anything other than emails pandora and possibly facebook does not mean i am making the laptop work hard.

I bought this for 600+ at best buy and exactly 1 yr later screen went black. What you guys need to know is that the computer is on and working just fine. If u connect it to a tv/monitor you can use it. Use a monitor cord to connect. The screen is black, i think the excessive heat burns out the screen but your laptop is fine...fyi. But if anyone wants to help round up enough people b/c it looks like its a manufacter defect, we can file class actin law suit. [Personal Information Removed]

I have had problems with this since day one!
Purchased in may 2009.
New hard drive 2 mos later now on 4th hdd. battery crapped at 12 mos. jsut used it for browsing
Now the permanent SLEEP mode. total junk. Dont blame AMD just HP and thierlack of integrity or quality!!
You guessed it.. my screen goes black. here's the catch though, the way my laptop is, it has a touch pannel to control various aspects of my laptop. When by screen goes black, my touch pannel's sound goes from on to off, (white to orange) and my Wi-Fi also goes off (orange to blue). After the screen goes black, those two things happen, and eventually my computer will restart ITSELF most times, but usually i just manually turn it off, and back on by holding the power button, because waiting for it to restart could take 10 mins or more. After I turn it on, I see the usual windows could not shut down properly, please choose the following action, I always choose start windows normally. This computer isn't even a year old, and i DO have a warrenty.
On a side note, I spent awhile talking to HP Services before, because a similiar situation occured as described above, but vista wouldnt even load, my backround wouldnt show up, and nothing would respond. they told me it was a virus and i did a whole system restore. granted the same problem keeps happening.
Other info you may want to know - I do play World of Warcraft, but this is a 32-bit opperating system with a ATI Radeon 3200 HD graphics card.
-The shutdown happens daily, sometimes twice.
-it is vista.
Any help would be awesome, I'm afraid HP won't cover this in the warrenty if something is wrong.
Never again HP......

I have the same issue with my dv4-1225dx, first connectivity issues, then the black screen with the blinking lights. Will HP stand behind these?
Mine was gently used and never left the house, very disappointed.

Ok heres the problem for every one of you. HP DV series laptops are known for inadequate cooling of the GPU. It overheats and therefore you lose the picture on your monitor and if your monitor does not work but you can use a monitor externally, this is not your issue. If the GPU was too hot neither an external or internal monitor would show an image.
This is a 64-bit CPU running a 32-bit operating system which means the CPU is working harder than it needs to. Multitasking is very intense on 32-bit systems and requires higher amounts of cycles or CPU usage.
For those of you whose computer may take 10 plus minutes to shutdown you have installed too many programs on your computer that have been added to the startup of your Windows. What this means is that for every program that has to start up at the beginning it must also be shut down when you turn your pc off. To correct this problem Open the Start menu and type MSCONFIG This will open up your system configuration. Navigate to the Startup Tab and uncheck all unneccessary programs ( that means any programs that Windows does not require to start), Leave MS services and Intel/HP services ON.
As noted before a dust build up of the cooling fan is inevitable in any laptop or desktop pc. A can of compressed air is not strong enough to clean off the dust from within the heatsink and the fan as the fan must be stopped in order to properly clense it. An expert technician or someone with experience should only clean out the inside of a laptop. There are many screws that must be put back in place much like a car engine. Some provide grounding for the electronics. But anyway a can of compressed air does not have a high enough PSI to clean out a laptop and this must been done with a high volume compressor.
Unfortunately the issue of high in these laptops eventually will cause the GPU to unsauter itself from the motherboard and will require a motherboard replacement. If you do not know what this means it is the same problem XBOX 360's have with Red Ring of Death. Inadequate cooling results in a total failure of HP DV series laptops. There is very little that can be done to give these laptops a long life.
