HP/Compaq :: Presario Screen Black/power LED On
Feb 3, 2009
The screen on my wife's presario notebook suddenly went black on sunday. She was surfing on the net when that happened. The screen wasn't completely black, it was kinda gray-ish like the LCD light was still on. The power LED was also still on. She turned the notebook off and back on and the screen stayed pitch black. The power LED comes on, the fan is running and also the DVD drive starts running but neither do I see a picture nor does the HDD LED flicker.
I tried different things like unhooking the power, uninstalling the battery but nothing helped. However after a couple of restarts I was able to make it show the 'Compaq' logo twice. Each time the HDD LED flickered a couple of times and then the screen was gray again.
On the Compaq website they suggest to re-set the RAM module(s). Does that sound like a possible solution to anybody? My wife is going to check if the notebook is still under warranty (She bought it in August last year) before I try to mess with the RAM.

I have a Compaq Presario CQ61 Product: VM9496Q2X Model: CQ61-319WM, that has a black screen when I power up. The wifi button stays red and the caps lock flashes twice. I believe this indicates a BIOS corruption failure. I have tried resetting by unplugging and removing the battery, and holding the power button for 30 seconds. I have tried the f8 key and the esc repeatedly at power up. I have also tried pressing the windows and B key along with the power key but nothing worked.

I have a Compaq Presario CQ60. The Display does not appear to be working. When I turn on the laptop the display remains black. No boot up screen, nothing. I can't go into the bios because I have no screen. The screen remains black. The harddrive appears to be working and all other functions appear to be working but I am not sure because I have no screen.
Is this a known issue with the Compaq Presario CQ60?

I have a compaq presario CQ61-420US with similar problems below, except I have a black screen, fan turns blinking lights are the same (num lock and cap lock) but they are flashing continuously every second or 2. I have tried the hard reset with the ram fix, connecting an external monitor, changing the battery, and the power adapter to no avail. I also used compressed air on the vents just in case was stuffed with dust since it will overheat and may cause problems, but nothing.
One option I can think of is purchasing a new MotherBoard, but I'm trying anything else before that.

I have a problem with my Compaq Presario CQ61-325ED. It won't boot. What I see is a black/blank screen, with the numlock and capslock lights blinking twice every couple of seconds.
According to the blink codes, it seems the BIOS has been corrupted [URL] .... Sadly, no adequate solution is given on that page.Win + B or Fn + B at startup does nothing, pressing all the arrow keys gives me a continuous blinking pattern (edit: I can't seem to replicate this anymore...). I have also tried creating a bootable USB-stick with a BIOS update, but I don't think I have done it correctly, for it never gets activated (the light on the USB never turns on).
Also, removing/resetting the RAMs or just one of the RAMs does not work. Neither does removing/resetting the CMOS battery. How to successfully create a bootable USB-stick with BIOS update for CQ61-325ED?

When I pull the power cord to switch to battery power while in Windows my lcd goes to black. The only way I get my video back is a hard reset and reboot. Later on I tried this and everything was back to normal. Why is this happening? Is this some weird standby?

Purchased in 2009 with free upgrade to Win 8.1 Pro. Has been a great computer up to now. On power up, LED's and fan come on but screen is black. Can not see anything behind screen when shining a torch on it. Has worked twice since fault appeared, once on re-boot and once when pressing DEL key. Replaced battery on motherboard and tried combinations of the two RAM boards. Still not working. Have recovery disks, but they are for the old Vista software.

I have an ACER Aspire 5542g and i've had a problem with it lately, when I turn it on, the fan starts running, the harddrive turns on, and the CD drive starts up, the power button LED is on, but all that shows up is a black screen. I have tried the "Take out the charger and battery, hold the power button for 30 seconds", tried switching the RAM, tried taking out the harddrive, and all have been a fail. And I am honestly confused, because some of the time (rarely) it will turn on, and literally everything about the laptop is perfectly fine, and its like nothing happened. Until you turn it off.

When i press the power button laptop seems to be powering up and running but the screen is black. The LEDs for power and disk are on and i can enable the keyboard back light. If i try to turn the laptop on again and again then after some time it boots up ok and then works without any problems, at least until i turn it off. I tried to connect an external monitor but it didn't get any signal.
I'm not sure if it is connected but i think it starded after i did the system recovery. I use Windows 7 Home Premium SP1.

I'm working with a HP G72-250US Notebook and using Windows 7 64 bit Intel core(TM). M350@2.27ghz2266 mhz 2 cores
Is it the Mother board or the Harddrive? Replaced screen due to vertical and horizontal lines in color. Computer worked normal at times. I thought it was fixed but then while doing a HP diagnostic program the computer said to shut down because the batttery situation might harm the computer . I tested the AC adapter. I installed a new battery and at first it was working again. I updated and scanned with AVG & Malwarebytes. Did another HP diagnostic and at one point was told to restart. It never lived again to this point.
All it does is light up the power light and W/LAN (F 12). Blue lights are on at times indicating Cap locks and number locks are engaged. I did do a complete factory restore before it came to this point and updated the bios (to F 37) and downloaded updates for chipsets and Graphics also.(after screen installed) The only thing it does now is make noises at startup and power indicator is lit now Light keeps cycling.(light off, light on) in ten second intervals.

HP Mini 210-1000 ... Actually it's HP Mini 210-1060EV PC
From product specifications: Display: 25.6 cm (10.1") Diagonal WSVGA LED HP BrightView Infinity Widescreen Display BID (1024 x 600)
Battery has been dead a long time. My display drivers and BIOS have recently been updated from HP website. After a power failure and a restart, the display looks weird. It was shifted about an inch downwards with a black border at the top, over which the mouse will not go, and the taskbar is not visible as is off the bottom of the screen.
When I go to Screen Resolution from Windows by right clicking on desktop resolution is set as 1024x768, when I click on Advanced Settings, Monitor tab, Monitor is set as Generic Non-PnP Monitor (1024x768 60Hz). When I change to 1024x600 it looks blurry and stretched vertically, but the screen is still shifted downwards with black border on top.
When I enter Intel Graphics Settings I can do the same changes as in the Windows dialog box (640x480, 800x600,1024x600,1024x768).
In the Aspect Ratio Options when I select Fullscreen (No-Border) the Black border is fixed but the screen still appears streched vertically but the screen is cut off at the bottom with no Taskbar visible. Re-installed graphics driver as well as a few Monitor Type Drivers from windows, nothing changes. When I turn the notebook on, the HP Quickweb screen also appears as a 1024x600 stretched vertically with no black border at top but going off the display at the bottom.
It appears that Windows and Hp Quickweb see the display as 1024x768 60Hz after the power failure. Before that, I had installed some Windows Updates but nothing related to Display drivers. I only had a System Restore point from earlier that day (very low free hard drive space?) but that didnt do anything.
Guessing it's a registry/driver problem since no pixels are bad and the black border on top is fixed in Aspect Ratio Options when I select Fullscreen (No-Border).

I have a Dell Inspirion 1526 that when I turn on the laptop, the blue power light comes on and the lights all come on but the screen is black. I here my laptop running but it looks like my screen just stopped working. I wasnt sure what it was so I bought a new battery to see if that was the problem and the screen still does not come on. I had this laptop for about 3 years and thought it was the battery or charger and its not.

I have a major problem with my hp pavilion dv6-3143sa laptop.
I put it to a shop and they told me it was a motherboard/cpu problem and they couldn't source parts. I managed to get the parts. I put the motherboard first, but didn't work. I then added the cpu and put on thermal paste, but still didn't work.
My laptop will power on but I'm still getting a blinking light on the caps lock button and a black screen.

I have an Aspire V5-572P-6454. Occasionally I accidentally hit the power button on the side of the computer and it makes my screen go black. I can't figure out how to get me screen back, thought it was a lighting issue and tried Fn and the left and right arrows, but that doesn't work. Usually end up rebooting and losing what I've been working on.

I have an acer aspire v3-571gOn trying to boot up my laptop by pushing the power button, the leds light up and the fan starts ( I can hear it spin) and the laptop starts but the screen remains black and does not even light up. The screen remains pitch black without any change at all.After force-shutdown 12 to 13 times, I rebooted my laptop and the screen suddenly started working.This happened once before as well and I didn't think much of it untill it happened again. I don't understand why the screen randomly chose to black out and not respond until after several restarts.
I tried removing the battery, pressing power button for about 30 seconds, rebooting, starting without battery (with power source) and nothing worked. It randomly and unexpectedly started working (just like it had stopped).

I had exactly the same problem with my Acer Aspire 5552G with win7, I tried all things that was online e.g. New battery, Flashing bios, Fn + esc without battery when trying to start the computer and so on.
It started now and then and worked perfect but when I shut it down again it could take me up to 50 tries to get it started.
The problem was issues with the boot sector on the hard drive!
Finally I made an Win7 repair disc and started from.
I also checked for errors on the hard drive and it repaired some sectors before starting windows.
After that it works like when it was new. The computer was bought January 2011.

if I opened the screen anymore than 4-5 inches, it would freeze half the screen and turn the over half into a complete jumbled mess. I ordered replacement screen about 2 months ago, and w/ me being lazy and all, it's been sitting on my office floor. I've been using the laptop daily, but instead it stays on my desk and is running through an Acer desktop monitor w/o any issues whatsoever.
So I brokedown and started installing the new screeen today, only to get this when I switched the output back over to the laptop:
It made an audible whining noise both times I switched over, so I quickly switched it off. At this point I'm wondering if the cable from the motherboard to the screen is the issue, but I don't wanna keep throwing parts at a computer this only cost me $250 brand new.
Also, when I finally get this figured out...I can't remember which plug this mic connector goes into.
It can either go here next to the keyboard cable or over here by the fan.

I have a compaq presario V2000 and am having screen problems. The problem is that the screen is not lighting up when switched on.
I have tried two different new inverters to no avail. With the new inverters, when the computer has been turned on the screen will be fine for 10/20 seconds then go off.
I dont think it is the backlight as when pressing the small lid switch the screen lights up but then soon goes back off. All the wired connections seem to be fine.

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?

My troubles are as follows:
I started working on a presario v6130us laptop with a blue screen. The owner thought it was due to a virus when she opened a email. I went and wiped the HD and reinstalled windows XP pro. Had the darn thing working nicely.
Then I thought he computer was running a lil slow, so I decide to update the bios. From (I believe) v.07 to ver.29 from the hp website. At the restart, it never restarted, so I restarted it by pressing power button. Went into the same ol blue screen loop. The stop message is 0x0000007b. I looked that variable up on the microsoft webpage. It says it is a Win 2000 unmountable boot device. Prior to this message it was Stop 0x000000ED.
Does anyone know how to roll the bios back, or what could be causing this problem? I have done a quick HD test. so far it has passed and is now doing the "executing" test @ 20% complete. B4 the bios update, the test would say FAIL 1- 07.

I own the Compaq presario laptop and in October it started giving me problems. I would get a blue screen with an error warning. This progressively got worse. It seems the only way I can get my computer to even power up is to lay it on it's side. Yesterday I resinstalled the restore disc. Now (still with it laying on its side) I am getting an error called Windows Boot manager. It says, "Windows failed to start, a recent hardware or software change might be the cause. To fix this problem, insert the windows installation disc and restart computer." I did a computer check on the hard drive when it was up a few days ago, and it seems to be fine. I am running windows vista.

I just recently removed vista and upgraded to Win7 32 bit. I tryed to add 4gb of RAM, due to the factory 1gb it came with. However got a Blue screen Error. After that I only installed 1 of/ 2gb stick of RAM and it worked.
My question is, I need 4gb of RAM for this c700, Should I update the Bios for Win 7. By doing so will the c700 allow me to install the 4gb of RAM and work?
