Qosmio X300-13O - Black screen on startup

Hi, I have a problem with my Qosmio X300-13O.
When I turn on the computer the screen is black, I can hear the windows starting up but I can't see a thing. I've figured that when I remove the battery and plug in the power cable the computer works fine. So my question is: Is it a batterys fault or computer fault?
How can I fix it (working without battery doesn't count)?
I'l add that i still have a warranty (I bought my X300 on may this year).

Hi buddy,
Have you tried an external monitor on the notebook? Maybe the internal display is faulty and so you can work with an external monitor.
However, for me it sounds like a hardware issue and I think the internal display should be replaced but an authorized service provider (technician) can check this and exchange the hardware.
If your notebook is under warranty, the repair should be for free! :)

Qosmio X300 11S, Black Screen.

I have had this laptop for 2 years, besides quite a few overheating problems it has performed well.
In November last year i noticed my games where once again very laggy, a sign i interpreted as time for a full clean, so i sent it off for a service.
The game i mostly play is World of Warcraft, after i received my laptop back from the service i logged into world of Warcraft and played for an hour or so and got my very first black screen, sound was looping, mouse and keyboard unresponsive. It took me at least 5 minutes to shut it down via the power button.
The black screens/crashes just kept happening i checked i had all the latest drivers installed, so i tried rolling them back but the crashes just kept coming. Where as when they first started i could get a couple of hours between them, it was now minutes at best.
To finally rule out a soft wear problem/corrupt file i decided to reinstall windows, after reinstalling windows updating windows drivers etc i then reinstalled wow however it lasted only a few seconds before the black screen/ crash happened again.
So i wiped the hard drive again, this time i have installed nothing but the windows disks, so my laptop is just like it was the day it came out of the box, and i still cant play any game like solitaire with out this black screen/crash happening.
I have an extended warrantee but they refuse to look at it as its a soft wear issue according to there under righters. Any body have any idea ?

so i sent it off for a service.
What did they do? How did they service it?
They just take it apart check the fans are working correctly and give it a clean, removing the dust from the fans and the heat sink..
Did you actually reinstall clean windows versions by truly formatting the hard drive and reinstalling windows and drivers from scratch?
I have the recovery disks i made myself , I boot it and recover it from them.
If you reinstall windows 7 it will create a 100 mb partition and keep the old system files and others in windows old folder, have a look here it might help.
I have windows vista installed and there is a separate partition.
Prior to contacting my extended warrantee, i tried to rule out a soft wear issue. I even made a call to Toshiba Tech support the person i spoke to did a link up to my laptop, as i had mentioned the vista games also caused this crash he had a game of solitaire. This did as i expected, cause me to receive a black screen/ crash. However the person at the other end told me over the phone that when this happened, on his computer it showed my mem and CPU where both running at 100% just prior to seeing the black screen and being disconnected. So i do believe your guess of something being overloaded is correct i just need to be able to prove it.

Equium A100 black screen on startup

Toshiba Equium A100 laptop
Completely black screen on startup so please don't say go into safe mode etc, because I can't.
I can't see a thing.
Like once in every 100 goes it will come on and I can F12 to boot from the format disk but it eventually freezes before completion.
Video showing what's happening - BTW the buttons you see me pressing are Fn+F5 I've heard that that sometimes works, but yeah, it didn't.

Thanks.

Hi
Look not good dude I think its an serious hardware issue
I checked the movie and cannot hear a beep when the notebook passes the POST (power on self-test). So for me it looks like something wrong with the hardware
But did you try to connect an external monitor in order to check if something would be visible on second screen? Check this
You could also try this:
Disconnect AC adaptor, remove the battery, wait some time (3-5 hours), then connect both parts and try to power up the notebook. If this fails, well in such case have no many other ideas. Ohhh wait maybe you could check the RAM modules. Try to power up the notebook using one module in each slot

RAID 0 on Qosmio X300-13O

I have got Qosmio x300-13O and I would like to make raid 0, but in BIOS aren't any options to make raid.
How I can do that?

Hi
I think this depends on software but I think you will need to install firstly the OS and then the RAID software and then you could make some changes.
I searched also for some tips and someone posted this:
Go to disk management (My computer -> right click -> Manage)
There you will see both HDD. Click right on the square where disk 0 and disk 1 is listed and convert in dynamical data medium.
Then you can build a RAID with both HDDs.

Black screen on startup early 2008 macbook pro

I am very disappointed with Apple right now. My early-2008 15 inch macbook pro shows a blank/black screen on startup. The hd runs fine and I can dim and undim the backlight on the screen but it stays black/blank.
I talked to an Apple rep and she told me that it was probably my graphics card (which I asked her specifically about when I researched and found many other people like myself with the same issue and then the lawsuit that came as a result). Of course, Apple no longer replaces the graphics card (like a true business person would) as of December 2012 even though they know the cards in the macbooks pros are defective. The Apple rep told me that I would have to take it in to a Apple tech to get it "officially" diagnosed as the graphics card being bad (which would cost me @$150 just for it to be looked at!) and then I would probably still have to pay for the repair!
Of course this happened in the middle of the week while I was in the middle of working on a sermon and other presentation projects. So I had to do my best to try to work from scratch without access to the info on my hd because the graphics card is defective.
Apple, you know the card is defective so please just replace the card! I'm not asking for any perks or upgrades! Just to be able to use my Macbook Pro that, up until now, I have been bragging about and telling everyone how happy I was to switch over from windows!
HELP!! HELP!! HELP!! HELP!!

If you experience distorted video or no video . . . take your affected product to an Apple Authorized Service Provider or Apple Retail Store to determine which service and support options are available. If you plan to visit an Apple Retail store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/
No, it has not cost anything in the past.

Qosmio X300-13O - Is HDD getting slower?

My Device is: Qosmio X300-13O, with 600GB (two harddisks 300GB & 300GB).
Hello, for the past two years I have put/copy/cut/paste hundreds of GBytes (because of my line of work). Some one told me that with time the harddisk speed _well become slower_ (speically that I use eSata cable with my external harddisks; the speed is around 50 to 60 MB per Second )
*1. Is that right or not?*
If I want to buy internal harddisk, *2. Is there speed for it or all harddisks is the same?*
One more thing; If I used the harddisk which the windows on for this use, *3.does it effect it?*
Sorry to take your time, & if any one knows anything about this, PLEASE tell me. REGARDS

Hi DaYiM_1,
The HDD isnt getting slower after months or years of usage but Windows is getting slower due a lot of installed and uninstalled programs. With other words: HDDs are not getting slower, but Windows. Therefore its recommendable to reinstall Windows from time to time.
> 2. Is there speed for it or all harddisks is the same?
HDDs have different speeds, like 5400rpm and 7200rpm. Latter are faster but need more power and produces more heat. Normally 5400rpm should be enough for most applications.
> 3.does it effect it?
To be honest I dont know what you mean exactly. As I wrote, HDDs are not getting slower but Windows.

IMac 27 Late 2009 with Random black screen at startup of Windows 7!

Hi, I'll try to explain the my random black screen issue as best I can.
I have a boot camp partition with Windows 7 x64 Ultimate installed.
I used the USB method to install, all goes well and Windows 7 gets installed, I update drivers, install boot camp etc. all is good, right!
My problem is that everything seems to be in working order, but the built in LED screen will only get lit/active in 1 out of 5 times at startup of Windows, eg. the built in screen stays black/off (black screen issue), like the install issue on iMac 27 I7 w/ATI 4850.
NOTE! When booting OS X the built in LED screen gets lit/active on every startup.
So what I did was connect a second LCD monitor via Display port to DVI, this monitor/screen has no issues, it gets lit/active on every startup of Windows, even if the built in screen/monitor stays black/off (black screen issue).
NOTE! I have tested both the latest drivers from Apple (10.4 19/MAR/2010, found on the USB install method) and AMD ATI Catalyst Driver (10.8 25/AUG/2010). The issue remains on both Apple released drivers and AMD ATI released drives.
1. So to me it seems like there are some detection/communication issues between the built in monitor and the video card on Windows 7, as there is no issue detecting and activating a monitor connected to the display port.
Are we missing a monitor driver in Windows that OS X has, or is this a hardware issue that Apple knows about and compensates for in OS X with on load firmware, driver or a kernel fix?
2. Does anyone else have this issue on their 27" iMac Late 2009 I7, ATI HD 4850 machine?
If yes, did you manage to solve it?
Thanks for any help on this issue.
Cheers,
Kevin

Hi, I've seem to have found out the source of the problem.
The issue is related to heat, and an iMac 27" gets hot pretty fast.
If I boot the iMac straight after first start into Windows 7 I seem to get a lit built-in display at all times. I can also boot OS X first and then into Windows 7 and the built-in screen get lit every time as long as the iMac isn't hot.
Strange thing is that the monitor connected to the display port gets lit every time. So I can only assume that the heat only interfere with output to the built-in LED screen.
So this iMac is going to an Apple premium reseller for service, and I'll tell you guys how it went.

Qosmio X870-149 - Black screen after Update to win 8.1

After an update to win 8.1 I got a black screen after login , the only thing I could do was to press zero during startup and make a recovery installation .
It took 40 houres , I do not know why it took so long , but when it was over, the HDD was completely empty , so I installed win 7 instead , since I had not made ??a recovery CD . The problem now is that I still get black screen in between , and thinking that it might be a heat problem , I still have warranty , but I do not know if it applies when I installed win 7 on the machine.
I still have a warranty on my toshiba Qosmio

Hi
Well, the warranty covers the hardware related problems. It does not cover any issues related to the software.
Now the open question is: why the black screen appears?
Is it hardware or software issue?
What happens if you access the BIOS?
Can you see anything on the screen?
Is something visible on the external monitor?

Please Help: iMac black screens after startup logo + spinning wheel no cursor).

Hi, guys.
I'm in a fair bit of a desperate situation; my iMac's screen seems to shut down every time after the white startup screen. The Apple logo appears, & the progress wheel begins spinning, then after a while - when it would usually then go to the gray login screen - it would, instead, go black. I can tell that the machine is still on (I can still hear it clicking as it does during processing) but I'm unable to determine anything else. Nothing is visible on the screen - not even the cursor - it's as if the display had turned off completely. I'm not sure if the login screen sits beneath that black screen (I have tried to log on by typing my login details in blindly, but even if it does log in, it's hard to determine what state the computer is in without seeing the screen.
I have tried the PRAM reset (holding CMD+OPT+P+R) during both the white startup screen, & the black screen to no avail. It seems unresponsive because I don't hear any additional chimes that I've been told should be heard during a PRAM reset attempt. I can't even be sure that the command is being inputted correctly because the light on my wireless keyboard remains off during the process.
I've tried rebooting over & over again; the results are the same.
The steps that led to the problem occurred thusly:
1 - I was trying to clear some memory from my current session, so I scanned through my active processes, quitting anything which seemed to be eating up considerable amounts of memory.
2 - One particular process I quit was 'launchd' which was functioning under my profile username.
3 - After quitting launchd, all opened apps seemed to close, & it looked like I was forcibly logged off the machine. The screen froze during this point, & I decided to do a hard reboot to log back in.
4 - The problem began after this hard reboot; startup seemed to occur as per usual; white screen > apple logo > progress wheel > and then suddenly, a black screen where the login screen should be.
I've shown a flashlight into the screen while it's black & it seems well & truly like the display has shut down while the iMac continues in the background. I have had issues relating to my screen going black before, but they were random & intermittent; they didn't occur without fail during the exact same time immediately after startup, & could be remedied by using the CTRL+OPT+EJT keys.
I am on an iMac 2010, 27", using I believe Lion OSX. I am unable to recall additional specifications while the problem persists.
Could anybody please help me? I'm quite desperate; I was in the middle of some urgent work that I need to get back to as soon as possible.
Thank you I'm advance to anyone with advice on how I can go about fixing this.
,c.

Qosmio: X505-Q890 Black Screen BUT Computer has not crashed

I have a Qosmio: X505-Q890, my screen goes black after a few minutes. But if you look at it on an angle you can see screen and mouse moving around. I am assuming that the backlights are going out on screen. What is the fix. I am capabale of dissasembling laptop and repairing. What parts do I need to fix?
Thanks
Greg

It could be either the inverter or the backlight, but it's hard to know for sure. It could also be a loose cable, but that seems less likely to me (although it might be easier to check).

Black screen on startup Macbook Air 11 2013

Hello,
I decided to reinstall my OS X 10.10
So after restart i held "cmd+r", open Disk Utility and format my ssd, then start downloading OS X 10.10
But suddenly an error appeared, and I noticed that there is no SSD in Disk Utility anymore
Then I decided to reboot my macbook and try to reinstall my OS X one more time, so i held power button for 10 sec and then start again
After this the only thing i have is a black screen
I tried reset NVRAM and SMC - no results
Cmd+R - not working
I made installation drive and tried boot using option button - same
Every command I tried - nothing appear on the screen
Can You help me with this?
Thanks.
P.S. Macbook Air 11 2013 128GB MODEL A1465

You took all the reasonable actions that can be expected. Read the following Apple Support document to be sure there isn't anything you may have overlooked:
Troubleshooting: My computer won't turn on - Apple Support
It seems unlikely that a catastrophic failure would coincide with what you did, so perform the NVRAM and SMC resets again, making sure you did both of them properly. After that, schedule a Genius Bar Reservation.
The SMC reset procedure is linked in the above document. The NVRAM reset is as follows:
NVRAM reset:
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. If issues persist, your Mac's logic board battery (not a portable Mac's rechargeable battery) may need to be replaced. The logic board battery helps retain NVRAM/PRAM settings when your computer is shut down. You can take your Mac to a Mac Genius or Apple Authorized Service Provider to replace the battery on the logic board.

IBook G4 black screen at startup with code in upper left hand corner

I have had operating system issues for the past year, and recently had my OS reinstalled at a Mac Professional retailer. After two weeks of perfect performance, the chime stopped working on startup. This was the only problem for several days. Then when I would put it to sleep, the computer would not automatically turn back on, I had to manually reboot it. Finally, today, after the computer would not wake up and I had restarted it, the screen would flash to the apple logo screen WITHOUT the spinning wheel and after several seconds would shift to an all black screen with text in the upper right hand corner, waiting for a command entry.
The code reads as follows:
hfsswapBTNode: invalid node kind (-9)
node=22016 fileID=4 volume=Macintosh HD device=root_device
-sh-2.05b#
Any ideas?????

Put the install disc in the drive and start while holding the "c" key. Once satrted click through past the language screen and select Disk Utility from the Utilities menu. Highlight the drive on the left and click the Repair button. If it reports errors and repairs repeat the process until no errors are reported. If it reports errors it can't repair post the error message here.
