Boots up - Screen is blank

The S10 worked fine the few times I used it, maybe a total of 30 hours. Took it out last night after many months of no usage (I bought it for travel use). It seemed to boot up (with loud beeps) the hard drive is humming but the screen is blank. I tried the unplug, remove battery, hold down power key recommendation 3 times with no success. It is, of course, out of warranty now. Suggestions appreciated, otherwise it goes to a computer recycler and gets replaced with an Asus.

My ipad turns in but will not boot up. screen stays blank. I've tried resetting it and rebooting from itunes. It says it is done but the screen still stays blank. The apple icone will show up intermittetly.

I turned on my ipad after charging it and the screen went blank. I tried the home button and on off button and that did not help. I went to iTunes and rebooted the ipad and restored it and it asked me to reboot from the ipad but the screen is still blank. It will go to a blue screen if I hit the on/off button. What else is there to check?

If you restored the iPad, there is nothing else to check. I suggest that you make an appointment at an Apple Store Genius Bar and let them evaluate your iPad.

Windows 8.1 Boot Camp Screen is blank after boot

I installed Windows 8.1 Pro on my Macbook Air mid-2012 running 10.9.5 Mavericks and Bootcamp Assistant to create the install usb and download the windows drivers. After booting however, the screen always goes blank after the windows logo. I've tried an external monitor with no luck. I've verified I have the latest SMC and EFI firmware installed. I've tried using external usb keyboard/mouse. I've scoured the web for other things to try, but most people with this problem say you need to update your EFI, but mine is already updated.
I was able to boot into the 8.1 install via VMware fusion. That worked since it was using the VmWare video driver.
I've been unable to get 8.1 to boot into safe mode. Does anyone have an idea of what could be going on?
Jonathan

Are using a USB3 drive? If yes, please find a USB2 drive be able to load the KVM drivers. The Windows installer does not have a USB3 driver.
If you have installed Windows using EFI Boot, you will run into Graphics/Audio issues.

Unmountable Boot Volume on XP and screen goes blank before repair begins

The XP Windows partition was seemingly working fine until I turned on the laptop this afternoon. Took a minute or so longer to boot than usual and I was prompted when it did load to update Acrobat, which I did and it rebooted. Took longer to boot, perhaps two or three minutes and I received an Unmountable Boot Volume error. I rebooted a few more times, same result. I tried system restore to three previous dates over past ten days and was told after attempted reloading that it had failed and I should try another day. Worried about my data, I went to safe mode to back up C: drive.
The general advice from MS is to use the Windows installation CD to repair the boot sector. With the CD in, Windows will boot and show my normal desktop and files, though will on perhaps the third item to load to memory, the screen goes blank and the loading seems to continue, as I hear sounds though not sure if it is the programs or the repair.
There does seem to be an ability for it to boot, just not maintain it through full load. Any suggestions short of reinstalling windows would be welcomed. Thank you.

I was unistalling some usless programs when my laptop died & when I turned it on I had unmountable boot volume 0x000000ED (the blue screen)
If I hit repair windows it goes to a black screen with the mouse (nothing else)
Now I tried f8 & then did command prompt but after it had gone to the loading files screen it had gone back to the blue screens with unmountable boot volume 0x000000E
I DL windows 7 repair but how do I get it to install when I cant get past the blue screen?
so i decide to repair it my self and then i found this great solution what helps me

Hi Mofimac,
Thanks for visiting Apple Support Communities.
If your Mac is only starting up to a blank gray or white screen after updating OS X, you can find some useful troubleshooting steps in this article:
Mac OS X: Gray screen appears during startup
I recommend going through these first three sections first:
Disconnect, test peripheral devices and network cables
Perform a Safe Boot
Reset the NVRAM / PRAM

Hello nosaint1961,
It sounds like you are unable to successfully boot your computer to your desktop. I would use the troubleshooting from the following article to help troubleshoot what is happening named:
Troubleshooting: My computer won't turn on
http://support.apple.com/kb/ts1367
If your computer won't turn on, try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

Boot camp hangs at blank screen

I have an early 2011 MBP 15 with Lion and all the latest updates install. I removed the super drive and installed an OCZ 120 GB SSD. My current configuration is 120 GB SDD installed in place of the 750GB HDD and the super drive is replaced with an optibay that holds the 750 GB HDD. I have Lion install on the SSD and want top install Windows 7 using boot camp. I ran the Boot Camp Assistant, created a 100 GB partition on the 750 GB HDD and a Windows partition with a full Windows 7 installation disc inserted in an external USB super drive. I click install (or begin, I forget) and my MBP rebooted as it should. I saw the gray screen and the activity light flashing on my external USB super drive, but the screen went blank and simply hang with a flashing cursor. At this point the Windows installer should begin, but it does not. I tried a partition on the SSD with the same results. I checked the Windows 7 installation disk on a PC to insure that it works and is bootable (It worked fine on the PC).
I've been working on this for several days and googled dozens of web sites with no solution that worked. Any help worked be greatly appreciated. TIA!

I've been thinking,
since you have two harddrives,
1. restore the windows7.iso onto the hdd,
2. bootcamp and partition the windows part. on your ssd
3. connect your hdd, and fire up your mbp with your hdd holding option key
4. install windows to your windows partition
5. finalise it
6. delete your windows7.iso
BAM you have your ssd+hdd dual system.
this is just my thought, not sure if it'll work or not since i still haven't recieved my optibay yet

HT1444 Screen is blank on startup but works fine when doing a safe boot. What could be wrong?

I have a Mac book pro 15 inch and the screen goes blank on startup. Screen comes up on safe boot. Also updated OS on line and do not have a backup disk to repair from. What should I do?

got system to boot up in safe mode and went into disk utility and did a repair on disk permissions and restarted, now everything seems to be working as it should. Now i don't have to go out and buy a new Mac but than again maybe I should.

Screen goes blank on boot

So when I boot up arch on my netbook the screen goes blank but the system continues to boot normally in the background - this happened after a long delayed update to my system. It happens round about the time when the resolution of the screen changes early in boot.
I initially thought it was an issue with Plymouth (which it isn't) but it has been removed from my system completely. I do remember several months ago messing around with framebuffer support but as far as I was concerned I reversed the changes. KVM was also disabled when I uninstalled Plymouth.
Here is the system journal: https://gist.github.com/anonymous/857628ab8ee1f9bef850
As you can see the system boots no problem.
I used an old Arch live CD to boot and get this log so I can only imagine that it's system specific configuration issue. What concerns me is that the screen blanks so early in boot and I can't even get a visible TTY session - so surely it can't be an issue with the onboard graphics card? I don't know.. That's why I'm here.
Thanks for any help.

Hey, thanks guys, thanks berbae.. it turns out you were correct. I downgraded the kernel to a previous version I had in my cache.
I asume that the best way to track this bug would be to keep an eye on that ticket? Pardon my ignorance. Do you know if it's likely we will see a fix?
Thanks a lot.

HP G7000 G7096EA Won't boot, no post/bios, blank grey screen

My HP G7000 G7096EA Won't boot, no post/bios, blank grey screen - It does appear to get into windows after return is pressed, albeit with blank grey screen.
I've reseated the RAM/harddisk, tried the power button reset method. Left it overnight with power battery/power.
I'm at a loss now with what to try. It does look to be a dead graphics chip, which is a shame and will probably put me off HP for life!

Ok, I've stripped it down to diagnose. Due to the piss poor cooling on the graphics chip, it's fried itself and melted the solder underneath.
This was actually the second laptop I had off HP as the first broke within a very short time.
Needless to say, I'll be buying from Dell in the future! What a crock of **bleep** HP are.
Oh yeah! And HP wanted £16 + vat just to speak to some outsourced crappy call centre!

HT1212 screen is blank with the apple logo. Will not boot up after downloading the latest software. Any suggestions?

screen is blank with apple logo after downloading new ios 7. Any suggestions?

Hi, ronia90.
Thank you for visiting Apple Support Communities.
I would first try a reset of the device. To reset a device, press and hold both the Sleep/Wake and Home buttons for at least ten seconds, until the Apple logo appears. You may need to attempt this multiple times.
iOS: Turning off and on (restarting) and resetting
http://support.apple.com/kb/ht1430
If the issue persists, you may need to attempt a restore on the device via forced recovery.
iOS: Unable to update or restore

Screen Goes Blank, Hard Drive Stuck, Cannot Re-Install, or recover

I have somewhat a bizzar problem that even with several years of IT experience I seam not to be able to figure it out. I thought I toss it our here at Toshiba community in hopes of people's collective experience shedding some lights on my problem.
I hava a 3 year old Toshiba Sattellite A305D with updated BIOS to version 2.10. It came with Windows Vista Home 32bit and I had upgraded it to Windows 7 64-bit last Christmas. It was working fine till last month that I started getting sporadic blank screens. Here is the symptome with details: screen goes blank, backlight it on, but there is no content on screen. At this time the Hard Disk Drive activity light is steady lit. Initially the problem happened intermitently and sometimes it fixed itself after few minutes and screen would come back on, but when it started to happen more often, I started to look for some troubleshooting. Some people suggested that blank screen could be due to bad lid close button being stuck or Windows power management's CPU power being set to 5%. I have tried cleaning the lid button and fixing power management but no luck. Then, I tried re-installing Windows from DVD, screen never went blank till after the first few steps of setup to the point that it says "Extracting Windows Files". At this time I started to think this is a hardware issue. I took out the RAM, I installed it on my MacBook Pro and used it for few days, and I had no problem. I even diagnosed them with Windows Memory Checker in the list of Recovery Options and no problem was detected. So, the next suspecious thing was the video card or display inverter. I tried connecting the laptop to an external monitor to test the screen's inverter, and same thing happened and external monitor went blank. I used Windows Recovery options and left it on that screen over night and nothing happened so I concluded the video card is fine. Next, I had turned off the Wifi and Lan, but nothing seamed to change, so I concluded those are OK as well. My last coclusion was that the hard drive is bad. I took the drive out and coonected it to my Desktop PC and ran disk utiility scan to check for bad sectors and none was detected. So, I thought the drive might be totally broken. I went to local electronics store and bought a brand new HITACHI SATA II drive and installed it. At first same thing happened so I gave up. Since I didn't have the recovery disks, I ordered recovery disks from Toshiba and tried that. Save thing happend and as soon as it started copying files, it blanked out. OK. So this time I ran a different recovery option and formatted the entire hard disk and zeroed out all sectors. That took approximately 3 days to finish for a 500GB brand new hard drive. Seams a long time.After that I could install Windows 7 64-bit from scratch up to the end. However, things got gorry again when I started installing Updates and driver packages. I had read about some problems with ATI drivers and Catalyst software with .NET updates, so I did not install any driver from update site and made sure all .NET updates are installed. I had to install the updates slowly chosing a few at a time. Otherwise same thing would happen. I got stuck to the point that I could not update anything. Windows files seamed to be corrupt and turning on/off Windows Features in controll panel was blank, so I had to re-install again. I did Re-install successfully using the upgrade option. This time I installed .NET updates first before any other updates. Then I started downloading all Toshiba drivers. Aazingly, the laptop worked for few ours without the symptom. I managed to install most of the drivers and updates including Value Added Package, HDD/DVD Rom Patch, Registry Patch, Sound, Modem, Atheros Wireless, and Catalyst. Up till now things were ok. Then I ran Toshiba Hardware update patch, and things got really messed up. Windows never booted again and symptoms showed right after boot tried to load WIndows. I tried recovery options but System restore kept getting errors too and I could not restore any more. Since Windows 7 Install and Windows Vistal recovery to Factory Default from recovery disk did not work, I thought maybe I should try Windows XP. So, I got a hold of my old Windows XP CD-ROM and I took a stab at it. Everything went fine till it started to copy windows files. This time symptom was different. I got one of those XP Blue Screen of deaths saying Hard Drive is bad and I must run chdsk /F. So, I concluded HDD is the problem. Ran CHDSK and no problem. I formated the drive again using DISKPART and the problem still exists. This is a brand new hard drive. What is the problem?

Please include your full model number when posting problems on the forums. It can be found on the bottom of your laptop. "A305D" is only partial.
That's quite the problem. How often was it doing this? At some steps in your diagnosing, it seemed to get better, but I wonder if it was actually (temporarily) fixed, or if it didn't occur by chance.
Unfortunately I don't have an answer for you. Normally I'd suggest you get it serviced, but then you'd also be throwing more money at a three year old notebook when clearly you're knowledgeable yourself.
Hopefully someone in the community will have some suggestions. I have noticed that some people shy away from posts with large paragraphs of text. (I'm not saying that's correct, but it happens.) I'd suggest putting some bullet points at the top summarizing. If you feel like doing that, you can edit your message.
Good luck!

Pavilion G6 2249WM powers on but does not boot - black screen

I have a G6 2249wm that had a message that the fan wasn't working. I had the fan replaced and after it was replaced it would not boot. I could hear the fan running and the caps lock light blinked once about every 5 seconds and the amber wifi light was on. After researching and taking steps outlined in the HP Computer does not start (Windows 8), I found that the code meant that the CPU was bad. I had that replaced and the notebook is still in the same condition. Is there anything else that I can do to get this computer to work?
Pavilion G6 2249WM C2N47UA#ABA AMD A6 - 4400M
After troubleshooting a little more I find that when the laptop is started the hard drive does not turn on. I used a USB adapter to plug the hdd into my desktop and found that it does work. I then plugged a different hdd that I know works into the laptop and found the same issue. Does this mean that the motherboard is bad?

Hello @FLC123,
Welcome to the HP Forums, I hope you enjoy your experience!
I understand that your notebook computer is producing a blinking light from the caps lock, and that the screen is blank. I would be happy to help you!

Imac G5 will not boot, Grey screen. Please help!

Please forgive me if this posting is a bit lengthy!
My Mac had been on sleep mode for 2 days, when I tried to wake it up a message popped up stating that a system failure had occurred (Darwin Kernal version 7.7.2: etc). I shut it down and tried to restart only to get a grey screen and with the spinning gearlike timer and after about a minute the fan started to run at full power upon which I turned it off via the power button on the rear. I tried several times to re-boot but the same thing happened each time.
I have tried to start up using the ‘safe-boot’ mode (held down shift after chime and released upon seeing Apple logo and spinning gear timer). After a few seconds however, the screen goes blank and the start-up chime repeats only to be followed once again by the grey screen, spinning gear and fan running at full speed. No progress
The Apple website suggests using the ‘Software Install or Restore’ disc which came with the computer. However, I don’t have this disc, only ‘Apple hardware test’ and ‘Mac OSX Install’ (3 discs) came in the box.
I checked the system using the ‘Apple Hardware Test’ CD (by holding down the C-key during start-up) using both the quick and advanced check but no problems were reported.
I then ran Disc Utility from the first installation disc to repair permissions on the HD which was successful. However, after re-starting the machine, once again the same grey screen appeared with no apparent progress.
I then tried to check for damage using the ‘fsck’, recommended by Apple if ‘safe boot’ mode cannot be run. After starting up in single-user mode I typed the following prompt: /sbin/fsck –fy. It ran through a quick phrase list but then delivered the line ‘Volume Check Failed’. I faired no better when I repeated the process over again.
I have never updated the software with Apple updates since I bought the machine (don’t laugh), mainly because I don’t have a broadband internet connection at home, could there be a bug in Panther OSX that needed fixing with a later update?
I have no ‘add-ons’ plugged in other than the keyboard and mouse. I don’t think it can be a firmware problem, I am the only user and have not changed any settings relating to access permissions.
This is my first Mac and so my experience of problem solving is quite limited. I am not a Mac expert and to be honest am confused by much of the jargon. The computer is now two years old and therefore out of warranty so I don’t want to take it to my local Mac shop if I can solve the problem myself.
I’m a bit concerned as there are many documents that I have not backed-up (foolish I know).
I don’t know how I can attempt to rectify anything if the machine will not even boot-up in safe mode!?!
Could the problem be something to do with the PRAM settings, might the internal battery be dead bearing in mind that the machine is now 2 years old?
Would it be possible to re-install Panther from the original discs, I have read that this will not loose any files but can somebody confirm this?
Can anybody offer some advice as to what I might try to get the Mac to start-up and avoid any problems in the future? Any advice will be much appreciated.
Imac G5 Mac OS X (10.3) 80Gb HD / 768Mb RAM

Please accept my apologies regarding the time it has taken for me to get back to you. Since we last spoke I have been away on vacation.
Upon my return I attempted to follow your advice but it would seem that my problems are more significant than I had originally anticipated.
First, as you recommended I reset the PRAM by holding down the required keys from start-up, until the machine re-started.
I then attempted to perform the ‘Archive and Install’ process for OS10.3 (Panther) from the original software discs, making sure to select ‘Preserve User Settings and Preferences’.
My Mac first went through a ‘Checking your Installation Disc’ phase (10 mins) before starting the next phase ‘Checking Target Volume Consistency’. However, after only a few seconds it stopped with the pop-up message ‘There were errors installing the software’. I repeated the process but got the same message.
I decided to run Disc Utility once again from Disc 1, upon which I realised that I had previously only run Verify & Repair Disc Permissions, not Verify Disc or Repair Disc.
I decided to try to Verify Disc under First Aid, however, this was where the trouble started. I got the following message on screen:
"The Volume Macintosh HD needs to be repaired.
Volume Check Failed
Error: The Underlying task reported failure on exit (-9972)
1 Volume checked
HFS Volumes verified
1 Volume failed verification."
Obviously I am assuming this problem is preventing me from performing an ‘Archive and Install’. Now I’m a bit concerned that my problem could be very serious, bearing in mind that so many of my files are not backed up.
I’d be very grateful for more wise advice as to what to try next.
