HP/Compaq :: HP Nc8430 (Resuming From Standby-Blank Screen)
Oct 2, 2009
I have Windows 7 RTM running on my nc8430 laptop. It has been working great. The only issue is a standby problem. If I put the computer to sleep via the FN-f3 combo it goes to sleep like it should and wakes up like it should. My power profile is set to put the computer to sleep after 10min of inactivity. If after 10min I let the computer go to sleep on its own, upon resuming it from standby I get a black screen. The computer is on and everything is working with sound, just no screen.
I am assuming it is a possible BIOS problem or video driver problem. I have the most recent of each and have tried different video driver versions but no fix.

So I just got my Studio XPS 1340. Everything is good. Just installed Windows 7(clean install). But, there is a problem with the ethernet when the system resumes from sleep/standby.
I didn't test ethernet with vista. There seems to be no problems with Wifi resuming from sleep. Is this just a Windows 7 driver problem? I updated the bios, drivers, basically everything I can find I updated.
Still happening.
Also turned off "Turn this device off to save power" option.
Any ideas?

I have a DELL XPS L521X running Windows 10 technical preview.
I have been having an issue for a while that the computer automatically resumes from standby at seemingly random times. As of late, it is also staying on indefinitely (or until a low battery event at least), despite my settings in Power Options that specify standby after a given amount of time.
This happens when it is plugged in or not, and is (of course) particularly annoying when it is unplugged and in a case that isn't ventilated.
I have checked the system and application event logs, and don't see the kernel-power event when the system resumed, but I don't see any information on why it did so.
Also worth noting: I checked my LAN and WIFI adapter power management settings, and the "allow this device to wake the computer" box is greyed out.
specifically what hardware or software is causing a resume event? Do you know how to ensure that the computer sleeps after a specified period of time when on battery?

I purchased an HP nc8430 in 2006, and its been brilliant.
Its getting a bit long in the tooth and I am now after a replacement.
I do some moderate gaming so a dedicated video card is a must.
At present, I am looking at the Dell Studio 15/16 models as they seem to offer good bang for the buck. However I have been so happy with my HP Notebook that I would like to see what HP have to offer.
I have tried the HP UK website, however I totally hate the layout of it, and am totally confused with the myriad of options and model ranges. I cant seem to filter out what I want.
What I am looking for is a 15" (approx) laptop with a dedicated video card.

Lately (last two weeks) my gpu has been dowclocking itself, that wouldnt be problem if it wasnt happening ingames (wow, wc3, hl2), even with powerplay off gpu still downcloacks itself to 392/250 from 425/380 and funny thing is, gpu alone swaps between those modes arounde once per minute. also when i alt+tab gpu clocks itself back to 425/380 (all this is happening while ingame)
now that isnt problem in wc3, but in hl2 and wow couses low fps (3-4 )instead of regular 40+ making games unplayable
i am using windows 7 x64, with all the leatest updates, didnt test if this happens on xp but willing to try, problem is i lost my recovery cd-s :S
Week b4 this started to happen i used mobility driver moder and instaled catalyst 9.3, noticed significal fps boost in wow and hl-2, even tryed fresh win instal with vista64 drivers for gpu from hp page (very old drivers) still it didnt solve my problem, mbo has latest bios availible from hp.
Some help would be awsome as i'm rly out of options and what to do, and rly dont feel like reinstaling windows once again ...
could i somehow disable powerplay or owerride it with ati tray tools? problem is i cant run any 3d aplication if att is on they just dont wanna start.

The exact message is Power-On Password and a symbol of a key.
I am trying to clear this Power-On Password message on a HP Compaq nc8430. Searching though this forum and on the Internet, everyone mentions I should remove the laptop battery and the internal battery to clear this password. I have do so and left the battery out overnight and the password is still there.
I have found another mention of a IC or similar that is used on laptops to be more secure. I have also found mention that some laptops can be reset by a "jumper" or by touching points on a motherboard.

My friend gave me his broken laptop which is not too old. turion x2, 1gb ram, vista. He said one day he was using it and the screen went black. I turned it on and a fan noose starts but slowly stops. I don't really hear anything from it either. I also hooked it up to a VGA monitor and the it is black as well. Any ideas on what it isand is it easily fixed?

Basically I'm having some issues with my laptop battery, which seems to be stuck at a particular percentage. By this I mean that when its plugged in the indicator says:
However, when I unplug the mains the laptop turns off immediately, giving the impression that there is no charge at all.

I bought a tx1309au a little over a year ago; a couple of days ago I just noticed that it started to overheat alot. Then on Monday, when I turned it on, the screen was just black. It stayed that way for a whole 30mins and I had to turn it off. A few hours later I tried to use it again but still the same. My friend has a similar laptop and he theorizes that it must be the nvidia component at fault. Problem is, my warranty has just expired. Does anyone know how accurate his assessment is? And more importantly, how much it costs to have the nvidia replaced?

I have a "compaq presario v6210US" which worked great for a while then it just shut itself off and restarted and the screen stayed black. Now it keeps restarting itself but the screen stays blakc. I can hear the fan and hard drive and everything else running the way it's supposed to. I heard that this has happened to a bunch of other people so it sounds like a defect to me. How do I get it fixed or do I just pull the hard drive, toss the Presario and get a competitors laptop?

I just received from ebay a nvidia Quadro 770M 512MB
Quote:
[url] or[url]
as an upgrade for my HP 8510p which currently has ATi HD2600 256MB.
Both cards are MXM II (physically fit) however I'm afraid that this VGA is not on whitelist so it's not going to work - I only get blank screen, no error message, no POST, no chance of entering BIOS. I read that there is some tool that can modify BIOS - something called HP Tattoo utility however maybe it's obsolete now and has been replaced by some other utility - I can't even download it anywhere.

I'm more of a desktop user but my husband gave me this laptop on January 2007. Since then, I think I only used it for less than 20 hours (we don't have a wireless)... when we got out of town.
The last time I used it, about a year ago, it turned off by itself. I tried to use it again when I got home but the screen is just blank whenever I turn it on. What could be the problem? I don't think it's a good idea to send it for repair to HP as the warranty expired already.
when I turn it on, all the blue lights turn on... but the screen won't therefore I can't use it. Ealier, I hooked up an external monitor but didn't work. Could it be an LCD problem?
The notebook doesn't have any scratch or whatsoever. It still looks like new, yet not working.

I have a Compaq 3000 Laptop, it's almost 2.4 Years old now, over the period of time I dint faced any issues with my Machine.it all started yesterday.
I was watching a movie on my Laptop yesterday, after sometime the screen froze up but the movie was playing as I was able to hear whats going in the movie.
Later I tried restarting the machine, what i get is the machine boots up properly, but the screen doesnt display anything thing, it shows up a blank white screen, sometime when the windows XP loading picture comes up the screen shows light distorted colors but again goes white blank.
I did approached a local vendor for that but he says that we need to replace on the motherboard, I was not much convinced over his explanation over the issue.
I would like to know your views on what might be the problem with my Machine.
I am going to try over connecting an external monitor and see if LCD is the problem, but I would like to know more what all possible options are there which might be affecting my machine and how much would it cost me in the worst possible case.

I am currently stumped on troubleshooting error code lights for a clients hp compaq cq62. I have tried the hard reset, reseating the memory, and even plugging the notebook directly into the wall instead of a surge protector with the battery removed. I cannot find any solution on the HP site or any other forum site for that matter as to what a solid caps lock light and a solid orange light on the f12 key.
Currently I am thinking the client is might need a new back light for the system or a new cpu.

Does anybody have problems with standby or hibernation-function?
If my E6500 with XPprSP3 is switched to the standby-modus (via Fn+F1 oder by closing the cover) the screen stays black after wake-up with the power-button - and the system probably freezes

System specs:
Lenovo T430U
Intel i5-3427U
8GB PC3-12800 DDR3-1600MHz SoDIMM Memory
HDD 500G 7200rpm Toshiba
mSATA 24GB Samsung Cache
Win 8 Pro, upgraded to 8.1
I rarely use this machine but a couple of months ago I went to boot it up and found that I was not able to get past the Windows splash screen. Sometimes I don't even get the Windows splash screen, I just get a black screen. Rarely I get a Windows screen saying that it is diagnosing a system problem or something to that effect and I can even get to where it will allow me to do some Windows diagnostics but nothing ever comes of it and the process is extremely slow.
I called Lenovo, but of course my machine is out of waranty so the tech just gave me a few pointers and said I could send it in to the depo but the potential repair cost could range up to about 75% of what I paid for the machine in the first place. Anyways, after having me try a few things in the BIOS he suggested that it was likely the hard drive. I mistakenly thought from the time that I bought this machine that the OS was installed on the 24 GB SSD so I ordered a new SSD and swapped it in. This made no difference at all as I have now learned that the mSATA SSD drive is merely for cache to speed up booting.
I am afraid that this means the main HDD is at fault, and quite frankly, if I replace it I am going to do a fresh install of Windows 7. But I do have pictures and docs that I would like to salvage if possible.

Running Win XP on dv2000t. The Windows shutdown menu has 3 options which are RESTART, TURN OFF and STANDBY. When I click STANDBY the computer appears to turn off. I can't get it to turn back on except by restarting with the power button. Is there some special key combination I need to know? Apparently the computer shuts off when I click STANDBY.

I'm about two week in after purchasing a Dell XPS 13 (L322X)... I've begin noticing the keyboard backlighting fails turn on after resuming (opening the lid) from sleep mode. Depressing the FN with the backlight doesn't remedy only a system restart does. Could this be the result of flawed keyboard drives? If so how do I get the drivers?

I have a Dell Inspiron 9400, I think thats the same as an Inspiron E17-- in america (for some reason dell likes to confuse its customers).
My screen goes competely blank after the dell logo and windows logo show up on startup.
Everything works because I can still log into windows and shut it down using shortcuts and all the normal sounds are played, there is just nothing on the screen

I have an XPS M170, with the 7800GTX card installed. Been working perfectly for several months now then all of a sudden the screen went black, and I had to force a powerdown.
(I was only browsing the web at the time).
Turned it back on, and all that happened was the power light came on, the hard drive light flickered, then the DVD seemed to power cycle (the light came on and I heard it spin), even the XPS lights came on, but that's it, nothing else.
If I leave it alone, it remains in that state with no change, hooked up an external monitor to it, and nothing there either.

hope someone can help me here. Every time i turn on my laptop all i am getting is a blank screen on my laptop and my external monitor.
i am thinking of replacing the motherboard as the graphics card is aparrently soldered to it.Before i do this could the problem be any thing other than the card? I tried running dells screen diagnostic using the beep sound but there are no sounds at all and i cannot see any warnings or errors as all i have is blank screens.
Also if i change the motherboard when i switch it back on will i have video output straight away or will i have to configure anything first?
