Satellite L750 black screen on start up!

After using my new Laptop for three weeks (and only for 3 hours per day) suddenly one morning I pressed the start button and the only thing I got was a black screen with nothing else .No cursor , no sound , nothing at all , only black screen. Please I need help

I have the same problem with this Satellite L645-S4102. No Toshiba splash logo on startup. Just a black screen. There were BSOD problems before I got this laptop but I can't even get the laptop to bootup to even try and repair it. The laptop is out of warranty. On startup, it checks for usb bootable or DVD bootable disc (lights come on, but that's it). any help would be greatly appreciated. I tried taking out the batteries and leaving it for over an hour, held the power button to drain any static electricity, then put the lithium battery and laptop battery in and still get the same results.

Satellite L300D - Black Screen on start-up

Hi Guys, I need some help please. On Thursday I was on my computer and noticed the time was wrong I thought I must of done something wrong and was going to fix it. I went to restart my computer but it wouldnt boot just had a black screen. I knew I hadnt damaged the screen. After a bit of googling I read about taking the battery out and plugging the charger in and low and behold it worked!
On Friday I charged my battery up for an hour and put it in the computer and that worked too so I thought the problem was solved.
Unfortunately today my computer will not start at all with or without the battery in still get the black screen. The fan is going but apart from that its very quiet. I tried putting the cd in to see if that would do anything but it didnt.
Any suggestions please?

When I first got theToshiba Satellite, it came with Vista. It was UNUSABLE! I mean that I would have to restart it by removing the battery and disconnecting all power every couple of hours.
Toshiba wouldn't help me and microsoft would not help me.
They both blamed each other. So after paying over $700.00 I was disappointed.
After a year of struggling, I found the drivers for windows XP and installed Windows XP. The laptop was suddenly fast and it worked.
I don't like how hot it gets and the noisy fan on most of the time. A friend has a LENOVO laptop that works very good, and is very quiet.
I doubt that I would ever buy another TOSHIBA again, mostly because they did not support me when the laptop was unusable right out of the box.
Also 3 years is too short a period of time for the 4700.00 Laptop to go in the landfill!
Pathetic.

Satellite L640 - Black screen at start-up

When I go to start up the notebook I only get a black screen. I can hear the fan going and the start up sound happens to login but only a black screen appears.
Any suggestions to fix this would be great!

Thing is I don't really know what's caused it. I download a lot of torrents using utorrent and don't really use it for much else. It was running a little slow but basically one day just went to black screen and that's it. Is there a way to restart the settings?

Satellite laptop black screen on start up!

Last night my laptop froze up and after several minutes of waiting it out nothing was happening. I did a hard shut down and left it overnight. This morning upon turning it on all I get is the Toshiba start up logo and then it goes to a black screen with a blinking white cursor in the upper left hand corner. My only 2 options in the logo screen are F2 and F12. What happened and how can I get it back to normal? I'm starting to panic!

Please include your full model number when posting problems on the forums. It can be found on the bottom of your laptop.
Turn off your laptop, unplug all wires, remove the battery, and hold the power button for thirty seconds. Afterwards, reattach the battery and connections.
If that doesn't fix it, try contacting technical support by calling (800) 457-7777.

Satellite P300- Black Screen at start-up

Hey,
My notebook freezed the other day then shutdown. Ever since it has been unable to rebot. The power and battery light are on and when I go to turn it on it comes on and will ether stay on for 5 seconds and go off or stay on but still with a black screen.
Any of you guys plz help.

Hi
In your case I would check the memory modules firstly.
The point is that a faulty module would affect the notebook startup process you would not be able to access the BIOS if the modules are faulty.
You said the notebook shut down this would mean that the temperature has increase to a higher level and therefore the notebook powered off in order to prevent the hardware from damage
In your case everything can be possible as I said; RAM should be checked at first, if RAMs are ok, then other parts like CPU and motherboard should be checked
I think you have not many experience and not enough resources in order to run some tests and therefore I recommend contacting a technician. The professional guy could test the parts and if necessary could replace it

Satellite L300 - black screen at start-up

Hi
I have Satellite L300 brand new out of the box I have used it twice now when I turn it on the power light comes on but no screen.
Does anyone have any solution?

Can you see Toshiba welcome screen?
Have you finished operating system configuration (after first start-up)?

BLACK SCREEN on start up with 3 beeps, FREEZES when power unplugged, IF IT BOOTS splash screen freezes, OVERHEATING REQUIRED TO BOOT - 0x7B, Event 41 kernel-power

Issue: One day I unplug the power, the screen freezes and I get frozen music sound. I shut down, start up, I get 3 beeps (1 short 2 long), which indicates a Video failure according to the Thinkpad Laptop beep code list.
How I solve the issue day-to-day: I turn the heat up - I disconnect the battery and hard drive and plug in the power then turn it on. I will wait until the underneath is searing hot with a blanket blocking the fan's flow of air, I mean way hot because any
cooler and it won't start. Plug stuff back in, Hard drive first, Battery second, turn off with power button hold, unplug power, replug power.
I turn it on, no beeps, it goes past the first Lenovo screen, then gives me a prompt because it "didn't shut down properly" and continue regular startup. What happens next is the Windows logo appears,
and just as the animated windows logo starts to move (you see 2 small colored dots on the screen), it freezes. I see this every time, I know naturally that it means that the laptop is still too hot to go past that point, so I shut it down and try again. After
about 5 - 10 tries it will go past the splash screen and into the login area, then it's all fine.
Sometimes when I unplug the power from the back by accident it will freeze. By accident I mean that the connector wiggles it's self out easily. This unplug freezing thing started happening about 1 week before the 3 beep black screen problem started rolling,
so I'm putting 2 together.
Errors:
I got a Blue Screen of Death the first time I started it up with the overheating ritual, but I never got it since. It was 0X7B.
I got another Blue Screen of Death about a week ago, but came as it was on already and I had been using it, and said something about disabling Cache or Shadowing in BIOS. I never got it since.
Event Viewer events found:
1. Kernel-Power, Summary page.
There are critical events for a few things like Kernel-Power, Event ID 41, Task Category (63). There are 19 of them, each day 1 or 2 of them but mostly 1, so this maybe corresponds to my daily ritual.
"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
2. Kernel-Processor-Power - Event ID 37, task category (7)
"The speed of processor 1 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 71 seconds since the last report."
3. LMS - HCMI - Event ID 2, Task Category: none
"LMS Service cannot connect to HECI driver".
I came across a very sluggish performing control panel for Nvidia before and after this problem, and I tried installing a newer version, which I had to jump through a few hoops to do, like uninstalling first, not just updating. At first it said that the
driver wasnt for the system, which was wrong. I made it work somehow, but it was still sluggish. I rolled it back to an earlier driver, and now it works fine. No sluggish performance / slight freeze window thing going on.
MSCONFIG.exe, Boot Advanced Options: I have tried twice to change this 1 setting, check box "Number of processors" and change to 2 processors, because I do have 2 processors. I have been able to change
this in the past, but it does not save the setting now, and I believe this option was selected before I started having problems, and settings did not disappear then.
What could this be. The small round BIOS battery? The video card like everyone presumes? (I.E. the entire motherboard replacement), Software? The wiggly power input area? (Not enough power getting in?), Firmware of some sort? The BIOS software being wrong?

You are very wrong about that mystified. What do YOU think made my computer work without beeping at all hu? (I bet you're gonna tell me). I figured it out.
RE-INSTALL WINDOWS 7 OS.
SOLVED.
DOESN'T BEEP ANY MORE.
THAT IS A PART OF microsoft ISN'T IT.

Macbook pro-Freezes with black screen at start up.

Macbook pro-Freezes with black screen at start up. I've tried inserting the Mac OS X install disc to run the hardware test(Restart and hold down D), But it still does nothing. Just the black screen. Now I can't get the disc out. I've tried holding down the track pad key upon start up but that doesn't work neither.
What do I do??? Please help.

Remove the battery to find your serial number in the battery bay. Then you can look your MBP up on EveryMac.com:
http://www.everymac.com/ultimate-mac-lookup/
That will give you all the information on your Mac.
This is assuming that you have the MBP with the removable battery and not the unibody. The unibody has different graphic chips.
Good luck!

Time to take a trip to the Apple store genius bar for a free diagnosis. It could be a faulty GPU, faulty display or a bad display connection.

Presario f700 black screen at start up,

presario f700 black screen at start up, if left to own it flashes hard drive light once fan starts then turns off the starts again can get it to stop this sequence by pressing certain keys but screen always stays black and remote screen does not turn on. Have tried removing memory, hard reset, removed ram, have tested hard drive out of device. Anything else I can try.
Book says 15secs for a hard reset, one post said 30secs, which is correct

Hi, 30 secs is the better of the two options there. I am assuming the Hard drive tested fine? You can try turning the computer on with out the hard drive in it and see if you atleast get some text saying not bootable device or if you are able to boot into BIOS. If this does not happen you can switch out the ram chips. (boot with one chip then take it out and boot with the other) see if these work. If these steps fail its more than likly more of a hardware issue with the systemboard.
While I may work for HP, my posts and replies are my own and should not be mistaken for statments made by HP as a whole.

Mid 2010 Mac Pro, Black Screen on start up. Video works after I turn machine off, let it cool

My Mac Pro is acting up.
If I do a reset after its beenruning for a period of time I get a black screen at start up. I have tried multiple different monitor cables and nothing seems to work. It does seem to resart and I can here the start up chime but no display. If I unplug the machine and let cool for 1/2 ~ 1 hour it then turns back on with no problem.
Processor 3.33 GHz 6-Core Intel Xeon
Memory 24 GB 1333 MHz DDR3 ECC
Graphics ATI Radeon HD 5870 1024 MB
Software Mac OS X Lion 10.7.4 (11E53)
Display is the 27 inch cinema
Any ideas? Bad graphics card?

AC if you used it this once would pay for itself. Same for a good solid UPS - a good one can stop that 1/100,000 surge that takes out a modem (if you filter of course).
I've known people that never knew you could filter coax cable or dsl and we get enough severe storms it has been, not if it happens, but when.
Unlike the X1900 which had a air chamber and would cause clogging you really should not need to and be pulling it out to clean dust all that much if at all.
People have gone through 2 or 3 ATI 5770s and some 5870s due to what are probably design or bad batches especially the first months run.

NB 305 black screen on start up

My NB305N410BL displays a black screen on start up. It had worked fine the prior night. You can hear the "beeps" for the start page but no mouse or image ever. Any ideas on the problem? Thanks, Karen

Try this, disconnect the battery and charger. Hold the power button for 15 seconds and reconnect everything and turn on the computer...hopefully this helps you fix the issue...

I have a black screen at start up on my MacBook Pro. I installed Lion and it worked fine.

@tjk Thanks! My mother-in-law (also named Barbara, ironically) started having this issue this morning, so I've been looking into this. It seems to be a fairly widespread problem which makes me think that Lion (10.7.x) has exacerbated some issue with the card that may have already been in place. from everything I've seen, its a display-only issue (no data corruption, unless you force reboot). Still very frustrating for folks though.
Actually, thank you! I'd probably still be beating my head against the wall. That did ring a bell with another link I had stored: http://arstechnica.com/apple/news/2011/08/buggy-nvidia-drivers-giving-2010-macbo ok-pro-owners-lion-upgrade-headaches.ars
Don't know if it's related or not (and don't have the inclination to read all of them right now), but there it is. Will stay tuned for any new info. Again, good work and thanks!
