Hp Compaq Presario 2100 screen stays black, please help!

My laptop, which is a HP Compaq Presario 2100, stopped working. I'll try to explain the best I can what's going on:
When the laptop is plugged in and then turned on, all of the lights on it will turn on, all of them except for the power indicating light. The screen remains completely off, and it doesn't sound like the hard drive is running, just the fans. The CD drive and floppy drive both work. The weird part is that the things that do turn on only stay on for about 10-20 seconds and then everything shuts down. And no matter how long the laptop is plugged in the charge light never turns on and the battery in the laptop never gains any power. I can tell this because this particular battery comes out and has a manual indicator of power on its side.

Try this support document http://support.apple.com/kb/TS3281 and if that doesn't work, then make an appointment with the Genius Bar at the Apple store to have the hardware checked.

My phone got wet and screen is black, please help?!!

My phone got wet and the screen turned black after a while, it is still on because I receive phone calls and can answer them by swiping the screen where I know to swipe. The phone rings and I can even have a conversation on it. The screen is black however, I cant see anything else or do anything else. I'm going to take the phone to apple tomorrow to see if its repairable. Any suggestions??? Its a 4s, have it for about 4-5 months...

Try resetting the phone:
Press the Sleep/Wake button & Home button at the same time, keep pressing until you see the Apple logo, then release.

Satellite A200 screen stays black when trying to boot

Hello everyone,
My Toshiba Satellite A200 notebook is not working anymore, so everything started when I was playing a game, suddenly, the screen turned blue with some tiny text written on it. I had to hold the power button a few seconds to close it because nothing was happening on the computer. I then pressed the power button to open it. Everthing was going well, until the welcome screen. At this part, it was written "Welcome" but the Vista loading circle left of it wasn't turning.
After a few seconds, I decided to close the computer again, so I did hold the power button so the computer closed. Here is the problem : I tried to reopen it, but the screen stayed black. Nothing was happening. The power light was blue, but not any computer activity. So I let it like that a few minutes then closed it and tried again, but the same thing happened. I tried to disassemble it and noticed one of the two memory card wasn't fully in its slot. I fixed it, but it didn't fix the problem.
I also tried to plug another screen on it, but that one was also black. So I put back the screen on its computer and tried to boot my laptop and it worked. It was booting, but the first problem came back, the Welcome screen was frooze there. So yes I did close it again and then the same thing happened, the screen stayed black.
I don't think the problem is the screen because as I said sometime it goes to the welcome screen. Also I don't hear any welcome sound when the screen stays black as if the computer would simply not start up. And as I said earlier, I don't see any computer activity on the little light in front of the computer. And left of this one, I clearly see that the computer is ON because the power light is blue.
So this is my problem, next time the computer manages to start up I'll try to boot it on the SAFE MODE, but until then, I don't know what to do. Please, help me.
Thanks in advance,
MrRoy
EDIT :
After letting the computer turned off for about 30 minutes, I started it, and booted in safe mode. At this step, I securely closed my comptuer with the shut down button instead on holding the power button. Then I reopened my computer, and it booted and the problem was fixed. Now my notebook is openened and working.
So if this is happening to you :
1. Shut down you computer.
2. Wait for about 30 minutes.
3. Boot in safe mode
4. Shut it down using the shut down button istead off holding the power button.
That should work.

Finally, it doesn't work. I don't know why but my computer did start up after the 30 minutes, but now it's not working anymore. It just won't startup like I said later, with a black screen.
The computer did work for about half an hour. I mean, I managed to start it up but after executing a program, it just froze and I had to hold the power button to restart it. I did it about 3 or 4 times, then it simply did the black screen again. I think the problem is my processor, maybe it's damaged or something, could it be possible?
Because I see that the processor isn't working when I try to start it up.
So let's say it's damaged, would that be the symptoms of my computer?
And if it's the processor, the only way to fix it is to send it to a reparator or something, because I don't feel like it, I'd rather do it myself.
But right now, my computer is simply not booting, like I said in my previous post.
Thanks in advance,
MrRoy

How do i fix my iod touch... screen stays black

how do i fix my iod touch..... the screen stays black with the apple logo then cuts off again after like 5 minutes..... someone please help me ?

Please tell me it's not jailbroken. If it is, all bets are off. It is not...
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

Compaq Presario 2100 Laptop SSD Upgrade

I have a Compaq Presario 2100 laptop the was brand new in 2003. I have a newer laptop, but an currently trying to upgrade the Presario 2100 as much as possible. It's kind of a project now and I also want to get as much use as possible out of it. I have heard that the SSDs are super fast and would improve performance quite a bit. Has anyone made the upgrade to a SSD for their Persario 2100 series laptop already? All input is appreciated, especially all of the product info that was used for the upgrade. If nobody has done this, then does anyone know if it is possible to upgrade the Presario 2100 series laptop to a SSD?
Thanks,
Huck

Believe it or not the Service Manual is still available.
Manual
The Presario 2100 uses old school PATA (EIDE) hard drives which are different than the SATA SSDs you mostly see on the market. However, there are PATA SSDs. They cost a bit more per gig, obviously. I have put a PATA SSD in a laptop of about the same vintage as the Presario 2100 and it did improve the boot time and general performance significantly, but talk about the proverbial earrings on a pig!
This is a 64 gig PATA SSD which would be perfect for the Presario 2100 but is $90:

On eBay you will probably find 32 gig versions for a bit less.

HT201177 When I turn my computer on, I can hear it starting up but the screen stays black. Anyone know how to fix this?

When I start up my compute, I can hear it starting up but the screen stays black. Has anyone else had this problem and found a fix?

If you press the caps lock key does it light up? If it does then this indicates that your system is booting but the display is either not recognized, is not displaying any video, or the display is displaying video but the backlight system is not lighting up. As long as you've tried turning up the brightness then there is not much you can do other than take it in for a diagnosis. If you have a very bright flashlight you can turn on the iMac and then shine the flashlight onto various areas of the iMac display to see if you can see any faint images on the display. If you do then this indicates that the display is displaying the image, but the backlight is not turning on for some reason. It doesn't change the outcome, but at least you can assist the technician who is troubleshooting your iMac.
Please let us know what you find out.

I have a HP Touchsmart 300-1020 that powers up but the screen stays black. help!

I've been experiencing problems intermittently after shutting my TouchSmart 300 PC down. For the past few days when trying to turn it on ; the screen stayed black! I could hear the fan start rapid then slow down, I can see the green internal light blinking inside and lights on the outside of the computer but still nothing on the screen! I've tried plugging it into different outlets around the house was successful with one, but then, came the error message;
Page fault in nonpaged area. Today I tried to turn it on and I got the same thing described above. The computer's operating system is Windows 7 64-bit, purchased Feb. of last year and is refurbished.

Hi
You have a couple of options as I see it please run the Hard drive and Memory test check if both off then passes if any fails then you need to replace the part. If test passes you could try The F11 option to do system restore Or to do a recovery on the unit before doing recovery kindly back up data as it will be lost web link given below this will help you to let you know how to do the steps.
Troubleshooting Error Messages on a Black Screen that may Occur During Startup or Boot

IBook screen stays black at reboot no matter what keys I hold down

Hi, I posted a very similar issue a while back and was able to resolve it with some people's help:
http://discussions.apple.com/message.jspa?messageID=13196227#13196227
This time, I had to force shutdown cause the finder wasn't responding when I was transferring a movie to AppleTV. But now when I try to reboot, the screen stays black no matter what. I've tried booting while holding C, holding the mouse button and alt, but nothing brings me to the boot screen like last time. Similarly, I was low on Gigs, but I had a couple left and was in the process of making room. Would really appreciate any hep. I feel like a moron .

Were you getting warning messages that the hard drive is almost full? You may have corrupted the files on the HD.
Will it boot in Safe Mode? See What is Safe Boot, Safe Mode? (Mac OS X)
