Dell Inspiron 17r SE 7720 :: Screen Black - LEDs For Power And Disk Are On
Nov 25, 2014
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 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).

Dell Inspiron 7720 (17R SE) approx 2 years old, just started having problems about a week ago when turning on the computer. LEDs flash and dell quickset buttons light up; but then process just dies, screen is black and only the LEDs by the power symbol and on power buttons are lit, never reaches the Dell logo screen, no fan sounds or anything.
At first, hitting the power button to turn off then back on and the second time the boot process would work. Then it failed to do that, so I had to remove the battery, pull the power cord and hold the power button down for 30 sec's, and then it would boot normal. Now even that does not work, just have to keep powering down and re-powering and after a random number of times, 10-30 it finally boots normal, every once in while it will work first try. It seems to be getting worse.
I have used the Dell Diagnostic on boot (though it took many tries to get into the ePSA, that did not detect any problems. When I use the Dell Support Advanced, no problems detected, and I specifically rand the Motherboard (which included CMOS test) and those did not find any problems.
If I put the computer in sleep, it comes back fine. It is only when I shut down, laptop just will not boot until I hit power on (fail) / power off repeatedly until finally, as if by luck it works fine.

My mums computer has ended up in a Black screen "Preparing automatic repair" loop and therefore will not boot :(
None of the repair options work from the boot options etc, so I need the OEM win 8.0 installation disk, so that I can at least boot to safe mode and maybe correct from there once out of the boot loop.

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.

My laptop turn will not power up, circumstances I shut it down yesterday, packed it up, when I tried turning it on an hour later at school I couldn't get it to turn on.
Is this a hardware issue that can be repaired?
Computer: Inspiron 7720-17R, i17Rse-3589BK, Intel i7-3630QM
A. I have checked the power chord it works on my older backup Inspiron17, I two power adaptors the work. the original Dell and an after market rocket fish. both work on my older model Inspiron 17.
B. Without the power chord: open the lid, press the power button, it does not turn on the computer on or light up, none of the indicator lights do not light up.
C. When I plug the power adaptor in to laptop:
1. the power indicator light on the laptop does not light up showing it is plugged in.
2. pressing the press the power button it does not turn light up or turn the computer on, none of indicator lights do not light up.
3. (Original Dell power adaptor) the blue light at the end of the power chord goes out.
4. (Rockfish aftermarket power adaptor) the blue light on the adaptor goes from a solid blue to a blinking blue light.

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?

Laptop is on and plugged into the docking station which is "powered". Connection to monitor / keyboard and mouse is fine, however I'm surprised to see a lower power - plug is soon message. Isn't docking station supposed to provide power to the laptop?

I recently purchased an Inspiron 7720 in October 2012. A week ago, the laptop started freezing up while playing world of warcraft. I checked my Nvidia video card and there were some updates. I installed them and the computer started working normal again. On Saturday, while I was using Skype to transfer a file, the computer gave me a white screen and I had to hold down the power button to get it to shutdown. It rebooted and was working normal again. Then yesterday (Sunday), while using video chat on Skype the computer screen went into a flashing color pattern and I had to hold down the power button to get it to shutdown. Are there any diagnostic tests that I can run before calling Dell's tech department? I believe it is a video card issue but not completely sure.

My Dell 7720 has uneven screen backlight on the edges, is it normal? Do all the 7720 dell laptops has the same issue with the screens, or it is only my problem?

When I power up my laptop it won't go past the dell logo. I tried the removal of the battery test. I also tried running the diagnostics test and everything was good. There were no error messages. What can I try next?

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.

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.

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 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 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 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.

I have an Acer 7720-6604 notebook. For Power Settings I usually keep it on "High Performance" when plugged in (I'm usually gaming). I've found that when I unplug it with this setting, it acts like it's on "Power Saver" mode, which equals a big drop in frame rates when I game. I checked out event viewer and it shows this message as associated:
"Event 2, Kernel-Processor-Power
Performance power management features on processor 1 are disabled due to a firmware problem. Check with the computer manufacturer for updated firmware."
I've looked all over and can't find any way to fix this problem. I really haven't seen anyone else have the problem actually. It's bad though because it really makes games unplayable and shouldn't be happening on a relatively new laptop (bought it only about a year ago). I don't know what firmware I need to update or what I need to do if that's not it.
I did uninstall all of the empowering technology programs, including epower management. I'm not sure if it's related... I thought it was just a power scheming tool and windows has it's own in the control panel anyways.
Someone please help. I don't want to have to format or send it in for repairs if I can help it. Acer has an expensive repair fee (so I hear). I will format if I have to but I don't know that it will fix anything.
