G70-246US Laptop has black screen and won't start

Hi Everyone,
I have an HP G70-246US laptop. I received an errot that the computer could not find any Boot Disks. I turned it off and rebooted the computer and it would not come back on. I see nothing but a black screen. The power button light comes on but the hard drive light does not.
There is no sound of system startup, none of the f1, options work. The power button and the wireless button are lit and the dvd player allows me to put a cd in and eject it but nothing works.
I took the hd out and put it back in to make sure it was connected securely and still nothing. I am trying to get an idea of what needs to be pinpointed before I purchase a new hard drive.
Unfortunately, I am over my one year warranty time period. I really need to figure out a resolution soon as I design websites and without my computer, I can't finish my work.
Any help is greatly, greatly appreciated.
Thanks in Advance.

With the hdd out can you access the BIOS by tapping the F10 key after powering on? If so that would pretty well point to the hdd causing the problems. Your machine came with a 160Gb SATA hdd. If you will be using your Recovery Disks to reinstall you need at least that large to use them,can be larger but no smaller.

My ipad has a black screen and won't start, any ideas?

My Ipad 1 has a black screen and won't start, any ideas? It is charged.

If Paul's advice doesn't work try this.
Hold down on the sleep button AND the home button at the same time for about 10 seconds until the Apple logo appears on the screen - ignore the red slider - let go of the buttons and let the iPad restart.
BTW ...In order to start up under normal circumstances you only need to hold down on the sleep button for a couple of seconds or so until the Apple logo appears on the screen.

IMac G5 (iSight) Black Screen and Won't Start...HELP!

Hi,
I have an iMac G5 (iSight) PPC, 2005, model 1145. All was running well until a couple of weeks ago (see post/thread https://discussions.apple.com/message/16191999#16191999), when I had an issue with a grey screen, no start, and spinning wheel. Through a series of replies, it was determined that I probably had a corrupt file in the OS (10.5.8). I did an Archive and Install of the OS and all was running very smoothly....until....NOW!!!!!!!
At this point, I cannot start up at all. When I turn on the computer, I get a 'light', but in a few moments, the fan gets loud, stays loud, and the screen is just black.
I tried to start up from my Leopard Disk, hoping I could run the utility....but that didn't work....AND NOW I've the install disk stuck in the drive!!!!!
I also thought it might just be some bad RAM, so I took that out and tried to start up again, but that didn't work either.
At this point, I'm clueless and hope that someone might be able to offer some good advice.
Thanks,
Sandie

Just repaired my iMac G5 with complete boot failure, it all came down to capacitors, there was an industry wide use of sub standard/sub spec capacitors at the time the imac G5 was manufactured, due to a manufacturer using a capacitor recipe missing one ingredient, This caused the imac G5's to fail at a much faster rate than they should have done, I had to replace half the capacitors in the power supply and 5 of the higher rated capacitors nearest the power supplies internal vent onto the logic board once this repair was affected, my machine worked perfectly.
take the cover of the back of you imac G5 and see whether your imac version has some led diagnostic lights and check whether the power diagnostic led light lights up properly when started, there are tutorials for this on the web also a light there that indicates whether gpu is communicating with the display properly. all led internal green lights should light up, apart from the right hand one of the four.
with your dark screen and sleep light on symptoms it seems quite likely a surface mount BGA graphics chip failure, but to be honest it could also be a capacitor related issue, if your not into stripping the machine down and soldering capacitors then the machine for you is probably a right off, just try a pram reset boot before giving up, I had similar sleep light no boot scenario on a macbook pro, and a full stripdown got it booting again.
the power supply in the imac G5(als version at least) gets very hot and has no fan of its own and is dependant on the one internal left hand open motherboard fan for its cooling in my opinion it gets too hot, there is also no temp sensor for the power supply to give you an indicator as to how hot its getting, I feel the the heat venting from the overheating power supply internally is what cooked the capacitors nearest it, this is a flaw in the design of this machine. One way to reduce this issue is to perhaps use some kind of extra fan control software to boost the based speed of motherboard fan, whilst at the same time placing and extra entry quality pc fan thin filter foam on intake underneath to prevent any extra dust intake because of the fan speed increase so as to protect the machine from clogging with extra dust and heating the power supply further

Hard Reset: HOld the home button and the sleep/wake button of your iPhone for about 10 to 15 seconds at the same time. Holding down both buttons at the same time till you see the apple appear

Iphone 4s is working for example can play,music recieve texts ,calls ect but has black screen and have tried the force shutdown method but still can see what im doing on the screen

Did anything happen to prior to your phone acting this way? It sounds like your screen is dead, but it is hard to say without knowing what what the cause.
1) was this a gradual problem? Did the phone screen start dimming a couple months ago and now has degraded or after some event (known or unknown to you), the phone started behaving this way.
2) Can you give more specifics on the problem? You said you have a black screen, but also you can see what you're doing on screen. Is the screen just really dim? Is the screen completely black? Does anything else besides attempting to reset the device cause it to flash white?

My iphone 4s automatically getting turned off (blank black screen) and not getting started until full battery discharge. Even on long pressing power button - screen doesn't showing anything - not even "needs charging logo".
This is happening only since I have updated to new ios version (ios 8.1).
Is there anyone facing similar issue?? Any suggestion?!?

Ipod touch 2G is black screen and won't restore in Itunes (error 21)

I have aquired an Ipod touch 2g 16g that I was hoping to make a present to my daughter with. The device is I guess what is called "Black Screen of Death". I can't get any image to display on the Ipod when trying to charge (which it apparenlty accepts) the item or when trying to connect it to Itunes. Itunes recongizes the item in recovery mode, and attempts to restore the item and consistantly gives the error 21 message. I am using Windows 7 and have tried to restore the device on a laptop running Win XP with the exact same results. The screen will turn white during the process, and the machine will from what I have read and believe go into DFU mode, but it stops with error 21. I am a Noob and have googled and googled for a week now with no luck. I have tried the reinstallation of Itunes, all the updates to both Itunes and the machine, no security software, the works. I tried connecting it to older son's laptop running Win 7 which he uses for his Ipod 2g 32 gig without problems. My device was recognized on his machine, and he said on his Itunes he briefly saw songs on the device he did not have on his machine/device in his library before it hung again in the recovery mode loop. I have read different articles and tutorials on jailbreaking and tried loading just the 'oem" firmware from apple with Redsnow and thought i was successful. The device went through the process of white screen, several boots/dings of on my PC, and then an image appeared on the Ipod of "loading Jailbreak data". After a few moments/minutes it then began what I believe is displaying the "verbose" booting running the lines of text on the screen. I then notice it to stop and give me an error of something to the affect of init failed, and then a "lan error, watchdog timeout, giving up, a long pause, then quick scrolls down the screen and reboot back to white screen. Holding the power button or home/power button puts it right back to a black screen and in the Itunes recovery mode loop/error 21 again. Can anyone please help me resolve this issue before I pull what's left of my hair out. I would love to get this working for my daughter before her birthday. Thanks in advance to anyone who helps.

Common, no one has any ideas? Well, don't know if this will help, but here's some new data to process. I noticed that when I was trying to load the firmware with Redsnow w/o installing any options to include Cydia I got errors displayed on the Ipod such as WMR NAND format invalid; NANDLegacyFTL failed. Someone has got to know something. I would appreciate any ideas or thoughts from anyone with any idea. Thanks

Ipad was working fine and now has black screen and wont turn off or on or do anything

Ipad was working fine and now is a black screen. Won't do anything now

Is it charged? If not charge it with the supplied charger.
If charged, have you tried resetting your iPad?
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds).
No data will be lost.

Imac has black screen and 9 beeps

I am not finding any help in Support articles. I have a grey iMac 20" that is showing a black screen and giving 9 beeps when powered on.

20" Imac has white screen and freezes at start-up

my 20" imac will not start....help...All I get is a white screen and tone at start-up then it stays white. I tried hooking up a bootable firewire drive and pressing the alt/option key at start up nothing. I also tried the command/option/p/r at start up, it will reboot to the same screen. I also tried running the hardware diagnostics at start-up...no response. Computer was purchased on Nov .4 2007, warrenty just expired.
Help......Please....

I had the exact same problem today. My iMac 20" (iMac 8,1) would't boot any more, staying stuck on a white screen immediately after the normal start-up chime. Nothing worked (no safe mode, no DVD boot, no disk selection icon when starting with alt pressed, no Apple hardware test, no parameter RAM reset, power management chip reset had no effect, no verbose mode, not even open firmware).
I browsed the forums, but what I found didn't help, so I was about to stop trying and have it fixed by Apple. But my son told me he had noticed that after "a long time" (he's 4...), a folder with a flashing ? would appear. I figured that wouldn't happen in case of a severe hardware failure, so I tried one last thing: I hooked up an old PowerBook in target disk mode via Firewire and restarted the iMac. I tried several times (with and without alt pressed), but nothing happened (when pressing alt, a functional mouse pointer would appear, though).
Then I restarted a last time and left the iMac sit there on its white screen for about 20 minutes... and that's when the miracle happened: it finally booted off the target-disk mode PowerBook's system!
I ran Disk Utility, which saw the iMac internal HD as disk2s0 (or something like that), and launched the disk repair process. After about three error-ridden verify-repair cycles, the green ok message finally appeared and the volume mounted as if nothing had happened. I rebooted off the internal disk without a glitch, and I still have to find damaged or lost files.
I guess I was lucky that my HD problem was benign enough to be cured by Disk Utility. But even if that had not been the case, at least I'd have known that the HD failed, and maybe I could have saved some files using recovery software. Whatever the case, if you've got an external bootable drive, it's definitely worth trying before handing your iMac over for (usually horribly expensive) repairs.
Good luck!

Satellite A100 has a black screen and won't load into the Bios

I bought a Satellite A100 - (model psaa8c-0fh00e) about 5 months ago. it was left on over night which is not uncommon and when i came back to use it about 15 hours later it was just a black screen. moved the touch screen and its keys and nothing happened. so i cold boot it and it turned off. i then turned it back on like normal and the notebook turns on but the screen is completely black. it's not even loading the normal Toshiba Bios screen.
Now my question: is if there is any way I can fix this, i am familar with computer and parts. I just don't get this one cause i've never had to reflash the bois or anything like that. I'm just not sure how to turn and i really don't wanna have to take it into a shop, any suggestions would be helpful.
thanks in advance.

Hi Conrad,
If your A100 powers on normally (HDD spinning, optical drive LED flickers, fans turn etc.) then I would suspect that your LCD or FL Inverter has failed. You can check this by connecting an external monitor to the notebook to see if that shows the normal display.
On the other hand if there is no activity at all from tour notebook when you power it on then I would imagine you have an internal hardware fault, possibly the main board, which will need to be checked by a Toshiba Authorised Service Partner since the unit will still be covered by the warranty if it is only 5 months old.
regards,

Why does my iPad have a black screen and won't turn on even when I try charging it

I just got a survivor case today and put it on my iPad and it stopped working and just has a black screen even when I try charging it

Not charging
1. Reset iPad
2. Try another wall socket
3. Try another cable (make sure it's an original Apple cable)
4. Try another charger (make sure it's an original Apple charger)
5. Clean Lightning port with compress air or new paint brush

My mac book pro has a white screen and won't start up

My Mac book pro has been running slow, so I thought I would shut down and reboot. It wouldn't reboot past a white screen and an apple logo. I have rebooted several times and after an hour or so it still won't go any further. Any suggestions?

Howdy Lowana42,
Welcome to Apple Support Communities.
It sounds like your MacBook Pro has a startup issue that is causing it to only display an Apple logo. Try the suggestions in the article below, they will resolve most issues like this one.

Premiere will freeze at loading screen and won't start. Running win7 64bit

Hi, I'm having a bit of a problem here.
I just recently upgraded to CC because I had this issue with the CS 6 versions.
The problem:
Premiere Pro, inDesign, Illustrator and After Effects won't start. They will all get stuck at the loading screen. The weird thing is that Photoshop and Lightroom work without any problems.
I've tried restarting, completely wiping all Adobe Software with the cleaner tool and reinstalling. I've contacted support via chat and the couldn't find a fix. I then looked for weird processes in the task manager and found out that after a while (2-5 minutes) of letting Premiere show a blank loading screen (no "Loading ..." / "Initialising..." etc), suddenly "Loading ImporterPhotoshopProxy.prm" will appear and a process called "PhotoshopServer.exe" will show up in the task manager. If I kill this process then Premiere will start.
Has anyone had similar problems? Can't find anything on Google.
Thanks in advance.

If you had problems with CS6 upgrading to CC or CC2014 will not solve your problems. You must have basic hardware/software problems that only will get worse going to more complex versions. Do you have any third party codec pack installed? You must have rogue processes running. When you start up your system how many processes are running, look at your task manager?
What is your hardware configuration?
