Z50 - 70 - black screen start (démarrage écran noir)

Q: Z50 - 70 - black screen start (démarrage écran noir)


I have a problem with my LENOVO Z50-70 processor I7.

State before the problem:
There was a system update just before this problem, if I recall correctly,
I used much less my PC than before (unloading the battery often thoroughly ...)

Symptoms during ignition:
- The LEDs mains and batteries are green on the front edge of the PC,
- The SHIFT keys do not light up,
- the screen remains black,
- there is no beep whatever emitted by the PC,
- the screen remains black,
- Hard Disk seems to be turning,
- the fan of the Graphics Card and the Processor turns a little at startup,

I tried :
- Ignition with or without battery,
- The ignition with or without mains connection (connection and disconnection that emit a powerful beep that I did not have before)
- Once the battery is removed, press the start button momentarily, nothing happens,
- Press the NOVO button momentarily, nothing happens,
- Once the battery is removed, press NOVO, nothing happens,
- interchange RAM cards,

I have not tried yet:
- hard drive-free boot and hard drive testing in an external case,

I heard :
- Replacing the motherboard battery?
- Replacing the motherboard?

What might be the other solutions to my problem? I am currently out of warranty.

Thank you in advance for your help.



Je rencontre un problme avec mon LENOVO Z50-70 processeur I7.

Etat avant le problme :
Il y a eu une mise jour systme juste avant ce problme, si je me souviens bien,
J'utilisait beaucoup moins mon PC qu'avant (dchargement de la batterie souvent fond...)

Symptomes l'allumage :
- Les leds secteur et batteries sont vertes sur la tranche avant du PC,
- Les touches MAJ NUM ne s'allument pas,
- l'cran reste noir,
- il n'y a aucun bip quelquonque emis par le PC,
- l'cran reste noir,
- le Disque Dur semble tourner,
- le ventilateur de la Carte Graphique et du Processeur tourne un peu au dmarrage,

J'ai essay :
- L'allumage avec ou sans batterie,
- L'allumage avec ou hors branchement secteur (branchement et dbranchement qui emettent d'ailleurs un BIP puissant que je n'avais pas avant)
- Une fois la batterie retire, d'appuyer lomgtemps sur le bouton dmarrer, rien ne se passe,
- D'appuyer lomgtemps sur le bouton NOVO, rien ne se passe,
- Une fois la batterie retire, d'appuyer NOVO, rien ne se passe,
- d'interchanger les cartes de RAM,

Je n'ai pas encore essay :
- le dmarrage sans Disque Dur et essai du disque dur dans un boitier externe,

J'ai entendu parler de :
- Remplacement de la pile de la carte mre ?
- Remplacement de la carte mre ?

Quelles pourraient tre les autres solutions mon problme ? Je suis actuellement hors garantie.

Merci d'avance pour votre aide.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

Can someone please help me? I'm a first-time forum user

I've got an Acer Aspire laptop here that has decided to stop loading/starting up.

When I turn the power button on:
- I can see the Acer logo screen (and also get into setup if I press F2)
- The cursor (_) blinks once or twice
- Then the screen just goes black/blank and stays that way

Twice (when I have left power on at the black screen), I have eventually seen this Windows Boot Manager message (maybe after 5 minutes each time):

Windows failed to start. A recent hardware of software change might be the cause. To fix the problem:

1.Insert your Windows installation disc and restart the computer.
2.Choose your language settings, and then click "Next".
3.Click "Repair your computer."

If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

Status: 0xc000000f

Info: The boot selection failed because a required device is inaccessible.
Unfortunately, I do not have the Windows installation disk.

I have tried using a System Repair Disk (on DVD, burnt from another laptop with same OS)....but got stuck when the broken laptop didn't detect or couldn't read the disk.

I also tried the Alt+F10 system recovery, but after 20 minutes on the "Please wait a moment..." screen, I gave up and turned the power off.

Please help. Thanks.

A:Acer won't start, Black screen / Windows failed to start

Hello noob and welcome to Seven Forums.

Can you get into Safe Mode via the Advanced Boot Options menu? If yes, you can check for damaged or corrupt system files by running a system file checker scan from an elevated command prompt (option two in the SFC tutorial.) If problems are found, run the scan 3 times and reboot the computer after each scan.

Safe Mode

SFC /SCANNOW Command - System File Checker

Another possibility from Safe Mode is to try rolling back your computer to a date/time prior to this problem occuring using a system restore point.

System Restore

Hello, my Ideapad 710S Plus-13IKB does not power on anymore.There is no noise and just a black screen. The keyboard also does not light up.Yesterday evening I have just shut down my laptop regularly. Today it is not working anymore. Since my laptop model does not allow to remove the battery, this is not an option for me as several support articles say.When plugging in the power supply, the small LED light at the side of the laptop lights up. But besides of that, nothing happens.The Novo button also does not work. Model Name: 80W3CPU: Intel i7-7500U 2.7GRAM: 8 GBSSD: 256 GBDisplay 13.3" FHDBattery: 4 cellOS: Windows 10 Home 64-bit Thanks for your help.

Hi I would really appreciate any advice i've been trying to fix for four hours without any luck.

I have all my pictures, uni work etc and im terrified i've lost it all. I've only had the laptop a year.

Any suggestion would be amazing

I received the following error message when I attempted to restart my computer:

C0000218 Unknown Hard Error

When I restarted after the blue screen it went into a check disk but would not finish the scan.

I have tried to start the computer in safe mode with internet connection and after a few minutes the screen goes black. I've tried to start it using last known configuration and the screen goes black. Everything I try ~ the screen goes black.


A:Blue screen & now won't start in safe mode, screen goes black

I'm writing from my husband's laptop because my desktop is completely dead.

We were out of town for several days and when we returned my desktop was running very slow so I attempted to restart it. It locked up, I pressed/held the power button and when it restarted it attempted to run a disk check. The disk check locked up and I had to press/hold the power button again. When it restarted I got a blue screen ~ stop: C0000218 unknown hard error.

Sometimes when I attempt to restart it I get: checking file system on C:
file system = NTFS

When I attempt to restart it in safe mode, safe mode with networking or starting in last known good configuration I get . . .

multi(0)disk(0)rdisk(0)partition(2)\windows\system32\drivers\ . . . (various items)

Now it won't start, not even in safe mode. Everything I try ~ I just get a black screen.

** I just tried to restart AGAIN and it ran disk scan, said it had completed disk scan and would restart, the screen went black when it attempted to restart and the screen is still black and it won't restart.

What can I do to get my computer back?

Any help will be greatly appreciated!

Background: A week ago on vacation, I opened my HP Pavilion dv7-2173cl (a laptop running Vista Home Premium SP2) and suddenly, green and black lines began forming across its screen. I was later told this was a pressure crack, although that is not what I'm posting about. Freaked out, that day I turned the computer off and on several times using only the power button, once foolishly interrupting a "Startup Repair" process.

Problem: When I got home I hooked up the laptop to my TV so I could see what was going on. After attempting to turn it on many times, I eventually got the BSOD with a STOP:0x0000c1f5 error. I couldn't access the Recovery Module (even to backup) or Safe Mode. Going into personally uncharted territory, I booted from a Linux System Rescue CD to delete the $TxfLog file that was apparently the cause of the problem. I no longer get the BSOD, I get a black screen (KSOD?) (sometimes w/mouse, sometimes w/o) after the "yellow bar" loading screen. I still can't get into Safe Mode but I was able to use a Vista repair CD I downloaded to (finally) backup onto an external hard drive.

What I've Done So Far: I've run chkdsk, checked the memory and hard disk from BIOS options, and run Startup repair. I did the kind of Windows backup where everything goes to one file.

I'd prefer not to start from scratch if I can avoid it. Thanks so much for any and all help guys, I appreciate it a lot.


A:Vista won't start up, black screen before login screen.

I couldn't access the Recovery Module...Do you have a Recovery CD, Windows Vista CD, or Recovery Drive (partition)?What happened when you tried to access it?------------------------------------------------------------You said that you were able to backup onto an external harddrive, so important data is safe.The best option right now would probably be to re-format.

A friend of mine asked me to look at his old XP machine because it simply will not fully startup. It does make it through the initial boot routine and the "Windows XP" splash screen appears but, shortly after that, the screen goes black. All you can see is a black screen with a white cursor in the middle of it. The system does not respond to mouse or keyboard input.

I used a Hiren's Boot CD boot disk to look around his system. He has about 40% free space left on the hard drive which seems to function correctly. I am presently running a virus scan (via the Hiren's Boot CD).

I've never seen an XP machine do this so I'm not sure what is going on. I believe he is running SP3 but I'm not certain of this because I can get it fully loaded to check.

Any help would be appreciated.

I'm using a Dell Inspiron 1501 laptop computer running Windows XP. The problem I have been experiencing is during start up. When I turn on the computer, everything begins to load but I am not allowed to do anything until the screen "blinks" to black and then back to my desktop. I then can access programs. If I attempt to do anything before the black screen "blinks", the computer nearly crashes as it struggles to execute the command. Any idea's? Thanks

So I wanted to disconnect my Microsoft account from my PC because I didn't that account on that PC and under the 3rd tab on the account preferences page in PC settings there was an account that went by the name of AHS-101[2] (that isn't the exact name of it just as close as I could remember) and i deleted it thinking it was the Microsoft account. I later found the Microsoft account and disconnected it from the PC. I then put the PC in sleep mode. When i attempted to turn it back on it would not display anything. I then proceeded to unplug the the PC entirely. When i tried to reboot the system there was nothing except a but a black screen with a flashing white underscore. Does anyone have any suggestions on how to fix this without loosing any of the files? Thanks for the help for anyone who replies!

Hello I have a Toshiba Satellite L305-S5921 with me and it seems that when I turn it on it takes a little while for the windows logo to appear and after it is done loading, it just turns into a black screen and that's it. The screen is still on but it is black. And I hear the system running like its supposed to. I can't put in any commands and I haven't tried safe mode yet because when I restarted the computer, it didn't even bother to load up the Windows logo screen like the last time I booted it up. Can anyone help me with this problem? I have a feeling its a problem with the video driver but I'm not sure.

Hello, I have a frustrating problem ever since I did windows critical update and changed anti virus and this problem occurred yesterday. Every time I reboot my PC, a black screen appears with a cursor shows up for a few minutes before going onto login screen/welcome screen. I did system restore back to a month and it still doesn't work. I uninstalled anti virus to see if that might be the case and the black screen is still there. I then reformatted my pc by reinstalling windows 7 again using the disc and the problem is still there. My pc is only one year old as well and it's quite fast and quiet. Normally when I startup my PC it goes straight onto the welcome screen/desktop without this black screen. What can I do in this case? Much help will be appreciated.

Sorry I don't have the specs for this computer as I am offsite but, when we start the computer it won't get to the Windows screen. After the normal initial screen it just goes black with the blinking cursor and never advances further. Weirdly if I opt to boot via the CD drive (even if there is nothing in the CD drive), it will advance and load Windows and function completely normally. The glitch is only apparent when booting up.

Fan still runs. WiFi button is red (ever since Windows 10 update last year). Caps Lock button does blink, but only once every 3-4 seconds.

I tried booting into safe with command, but still black. the task manage will not come up, the windows key will not bring up the start menu. I've tried a different monitor and it comes up the same. any thoughts before I ghost the drive and attempt a windows repair?

Hey all, I've been having a rather unusual start up problem, which I can't find relevant information on, through google:  
When I try to turn my laptop on, it only gets so far:
vaio logo

 logo.jpg   144.51KB
then black screen with tiny flashing dash

 dash.jpg   149.81KB
and that's where it stubbornly stops. Every time.
I can't even get to the boot menu. No amount of hitting F8 takes me to the boot menu, or produces ANY response (yes, it's definitely F8 on this computer). The only thing the computer responds to in this state is ALT+CTRL+DEL, which restarts it.
A bit of context:
Last night my computer had a small "blue screen" crash -- nothing unusual, this has happened to me before on this and other computers, without any serious damage. But this time, I'm having the problems described above. 
What I've tried so far
Here's what happens when I try to boot using my Windows Vista installation/recovery disk, downloaded and burned from this site.
Vaio logo, black screen with dash, and then upon hitting F8:

One thing to check first is if the drive is not dead or still usable at this stage. Try reseatting the hard drive but first inspect the pins and contact points if they are not damaged or dirty. If everything is clear, reseat it properly with some or most laptops have screws to keep them firmly in place. Remove the laptop battery and press the power button for half a second. Now try booting it up again. If nothing happens go here and use the bootable disc to try and salvage your data. Let us know how it work out.

Please can someone help me? I am NOT technically minded and so find it hard to sort out problems or even understand the answers (not a good start).

My PC has been running well - until today! I switched on, the PC worked, it booted up normally and got to the 'windows loading' green bar at the bottom. The screen went blank - the monitor did not go 'off' and neither did the PC.

If I turn the monitor off and on, the screen display is all there - windows has started and there's my desktop. Before I can do much with it though everything goes black again. I tried this a few times and the same thing happened. I booted up with my finger on F8 - booting in safe mode is no different - the PC responds as it should but the screen still goes black. By switching the monitor on and off repeatedly I limp forward to the point where I can do a 'windows repair'. This appears to work and I am now using my PC (obviously).

I have no idea if this will happen again - I wondered if some automatic update has clashed with graphics drivers but I don't know what I'm talking about nor what to do with the thought :-)

I was using the computer and an update was taking place. I cancelled the update and now when I start up the computer, it goes through the start up process, but when it is done all I get is a black screen nothing comes up. I have a Dell Inspiron 1720 running Windows Vista and it is extremely important to get this back up and running. It is my husband's business computer. Anyone that can provide any help, I would greatly appreciate it.


A:After Start up all I get is a Black Screen Please Help!

Try a Startup repair as described in this article

If the system stops responding in a similar way during the startup repair, it is a very serious problem, read these articles very carefully

I have an HP laptop with XP Home. The laptop is not booting into Windows. When I try to start it, it goes past the BIOS to a black screen with the safe mode and other start options. It allows me to make choices, but freezes after a choice is made. The laptop is out of warranty, so I would like to try to track down the problem without resorting to their tech support. My first impression is that the hard drive may be the problem as I know several other people with similar HP models who have experienced HD failures within the first year. The laptops of this model seem to run very hot as they have Celeron processors that are not of the M variety. Any suggestions as to where I can start to look for the solution?

IF it locks up no matter what choice you make [like even safe mode, last known good config etc] there's a few things you can do.

1. remove recently added hardware, reboot. fix? if no go to step 2.
2. get your copy of win xp [the cd] out and put it into the cd drive. turn off the computer. turn it back on, and boot to the cd [*****see note below]. while its booting to cd it could take a few mins. once at the setup screen chose R for repair, then on the next screen you hit the 1 for the os choice, then enter, then enter for the password, then you'll have a prompt.. just type chkdsk /r and hit enter. this'll take 45mins to run. when done turn computer off, turn back on.. let boot up if fix great if no then step 3.
3. r... Read more

Screen says this upon startup.
(Alert! OS Install Mode enabled. Amount of Available memory limited to 256MB. Strike the F1 key to continue, F2 to run setup utility)

Every tool I run on this machine says there is no HDD installed.
F1 does nothing and F2 just goes into the BIOS and shows no sign of a Hard Drive installed anywhere. Please help if anyone has had this problem.

I've a Packard Bell desktop PC running Vista Home Premium. Have had it for a couple of years. Have kept up to date with all relevant updates.
On Sunday when I turned on my PC and screen the screen did not display (remained black). Windows loaded and I then turned the screen off and turned it back on again and lo-and-behold the display was OK and remained OK thereafter. The same happened on Monday so I did a system restore to last Friday (when all was working OK). Today (tuesday) the same - black screen on start-up - occured. I had not added any software between Friday and Sunday, I do not use any 'hibernation' type functionality.
If I do a restart the screen displays OK.
Help I'm a bit lost as to what may be causing this behaviour ?
Any advice greatly received

One of my computers crashed yesterday when the circuits blew. It needs to be fixed.

So, I hooked up my other computer, Windows XP Media Center 2005, and upon starting the computer, I see the typical loading screen, but then when my desktop is due to show up, all I see is a tiny strip of my desktop at the top of the screen (or what I assume is such, because the strip is purple like my desktop). The cursor doesn't show up, and pressing Escape, Windows (by the Ctrl button) and the like, doesn't do anything. I even hooked up my other monitor, and the same thing happens.

The Windows XP was working fine in my old residence, if it is of importance. There have been no issues with either computer until the circuits blew yesterday. Everything is tightly connected, and I just can't figure this out with my manuals.

I am using my sister's computer to ask this, so thank you for being patient with my reply. I will be checking in periodically to see if anyone has a good answer. Thank you very much to anyone that can help.

Also, the Windows Xp 2005 was NOT hooked up at the time of circuit blow

Time for some bench testing, look in the hardware section of the forum.
Have you observed anti-static measures? Try disabling some items and boot each time. If you have 2 ram boards, remove one at a time.
If you just moved, reseat everything carefully. Did you jar it or drop it when moving?

Unsure of computer specs; I know that is a an HP computer.

This is my dad's computer, and he said that while he was watching "videos", the desktop PC popped up a BSOD of the Page_Fault_in_non_paged_area error type. After waiting several minutes to re-power the PC, the computer does not load anything, and the desktop emits out a loud and non-stop "whirring" noise. I decided to check the Ram one by one, and they all (individually and collectively) load up past the screen with F11,etc command options, but go no further when the screen becomes black (with a blinking underscore in the top left and an off-centered orange block). I've attached a picture of this.

Every time i turn off this new computer and then try to turn it back on, i get a blank screen. So i need to open the case, clear the cosmos thing by holding something metal to the two little sticks and then i can turn it back on. So i just decided to clear the cosmos and then install my Windows Vista OEM 64-bit. after i did that i installed my motherboard disk. Then it told me to restart my computer, so i did. and I'm at the blank screen. I'm not sure whats wrong but i don't want to have to clear the cosmos every time i turn my computer on, so what do i need to do to fix this?
