Won't power on, but power light blinks.. eh?

Howdy all,
I was just on my machine, just turned it on and was getting ready to launch a game, when it locked up. So I reboot... Nothing. Try again... nothing. Unplug the PSU, plug it back in, hit the power button... nothing but a blinking power light LED.
I've looked all over the site to find any info on this but can't seem to locate any. Does anyone have any ideas as to what is going on?
Any help would be greatly appreciated!

Ok, just got the Enermax 550w PSU w/ 36A on all pos rails, and I'm getting the same issue. When the PSU is plugged in and switched on, the power LED slowly blinks. When I hit the power button, absolutely nothing happens. Nothing powers on, and that darned power LED just keeps on blinking away!
I've cleared the CMOS, verified and reverified all the connections within the case. I've even played with the power/reset/LED/etc headers (such as making the reset button the power switch), but nothing seems to work. I'm starting to think it's time to RMA the board.
Any other ideas or tricks? This is, to say the least, quite annoying! However it was a great reason to get a fantastic PSU, hehe.
EDIT: I just installed a system speaker, and there are no audible beep codes.

Laptop won't start quickly but power wifi and caps lock light keeps blinking

Hi, it has happened before too but rarely but nowadays it happens on daily purposes.
When I switch on my laptop after leaving it for 8-9 hrs, it won't start up but instead power, wifi and caps lock light keep blinking. I tried removing battery and pressing power button for few minutes but nothing happens. Then i left it like that with lights blinking and after 15 20 minutes it booted. I did same yesterday too. I left it like that it booted after 20 minutes..so My question is "why is this happening? Is it a motherboard issue or is it because of cold moisturous weather here and laptop takes time to get warm up?" Should I show it to HP Service center?

Hi @Nishant5788
Welcome to the HP Support Forums. I see that you are having a problem getting your notebook to boot up normally. As for what is causing the problem the blinking Caps Lock should tell us what is causing the problem as it should be blinking in a pattern. This HP document Computer Does Not Start and LEDs blink has a chart that will tell you what the blink codes mean.
This is most likely a hardware issue and you can give us a call regarding repair options. You can reach HP Total Care at 1-800-474-6836 in North America or start here if you live outside of North America.

8900 - Won't Power on. Red Light blinks only! Please help!

I have a Blackberry 8900 and this thing is driving me crazy!
To start, I woke up one morning and had a white scrreen and an error 502. I wasn't able to fix the issue immediately since I had class. I'm usually more attentive to my phone but I'm in law school. Anway, the next day I went to try to fix my phone, it would not power on at all. I just got the red light flash. When plugging it in to my computer, I got the sound it was connected but the AppLoader, JML_Cmder and DTM would not recognize the device. Frustrated, I put the phone aside again to concentrate on school.
So, I've decided to give this another shot but now it's gotten worse. The phone does nothing unless it's plugged up and it's still just that annoying red light blinking. I keep the phone plugged and remove the battery...still that blinking and the pattern is long pause, blink, short pause, blink, blink, blink repeat. Again, there is NO ACTIVITY when the phone is unplugged. Same thing when I plug it into my computer. The battery does not make a difference and doing a battery pull does not work. My computer does not recognize my device at all (no sounds, no connection, etc). I have tried to let it charge from a wall charger and it did nothing but that blink pattern for 12 hours.
Is there anything else I can do? It's an AT&T phone I purchased and use with T-mobile and both companies are being asses. Any last suggestions before I buckle and just throw the **bleep** thing away.
Again, I have tried the AppLoader through c:\program files\common files\research in motion\app loader, I have tried using the Command Prompt, I have tried JML_Cmder, I have tried the battery pull, I have re-installed both the DTM and the Blackberry USB and Modem drivers...
Anything else I could possibly try? Also, does anyone know what that blink pattern means?
And please don't suggest what I've listed already. Thanks!

Just to make sure you haven't missed a step, when you tried the Loader.exe file, did you try the steps to fix a nuked BlackBerry? The trick here is to remove the battery on the device, open the Loader.exe file, go to the second screen, then plug your phone in without the battery. As soon as your computer recognizes the phone, click next. This should be able to catch the JVM and allow access to reload the OS. Then once you get to the next screen, you can reinsert the battery.
If you have already tried that, then see if you can ensure that the battery is charged in another BlackBerry, or see if you can try another battery.
If none of that works, then let me know as there are still some other things we can come up with.

Pavillion 21 won't power on but power light is on

My pavillion 21 will not come on although the power button lights up. The screen doesn't come on at all. Please help I've had it only a month and have no clue as to why it won't come on.

I agree. Pulling the batt resets the phone & usually fixes most problems. Also, BBs chrg with or w/o the mngr. Just let it chrg for a few hrs. Oh, & don't forget to plug in your laptop! Hope this helps.

Q10 has locked me out completely. Won't turn on but red light flashing to specific pattern

Help! Turned my Q10 off yesterday to reset as emails not getting through. Now won't turn back on - just a little red light flashing at top right of device in a specific pattern. Nightmare-any ideas??

Connect your Q10 to the known working OEM wall outlet charger.
After being connected several minutes, LEAVE it connected and remove the battery a minute, and reinsert... does it reboot?

Iphone 4s won't turn on, but flash light is on

Hello all, I have an iPhone 4s which is approx 5 weeks old, has never been dropped and has no water damage. The other day the flash light came on and I couldn't get it off but the phone was working perfectly fine. Then the phone died and now I can not get it to turn on. When you plug it into the computer it is not recognized and the screen is just completely black there are no signs of it saying its charging or anything, all that happens is the flash light turns back on. I have tried pressing all the various buttons for various amounts of time, both plugged into the computer and not plugged in, but nothing seems to work. I am currently in the Galapagos Islands for another 3 weeks so I can't go to any places to get any help and it is my only camera here so it's a serious bummer. If anyone has any suggestions please let me know, it is greatly appreciated!!!

personally the only time i have seen this is with liquid damage or fake parts fitted to the device
(if it is fake parts apple will have to deny service)
under the tab in the dock connector you should see a small sticker in the middle (white is good, orange/red is liquid)
also the same applies to the bottom of the headset jack in the top of your handset
if you have any further issue or still not sure as to why this is happening simply book a genius bar appointment at your local apple store via www.apple.com/retail

My Curve 9220 has a black screen and the LED light blinks red every 5 seconds

The phone won't come on and the light blinks red. I dont know what to do

Hi there,
If you have a good battery or the batttery is good enough then try those steps , it may help :
( Credit JSanders )
1) Make sure you have Blackberry Desktop Manager installed. BlackBerry desktop software
2) On your PC, go to Start > Run and copy and paste the following line exactly (meaning with the quotation marks):
"c:\program files\common files\research in motion\apploader\loader.exe" /nojvm
3) The Application Loader Wizard will appear -- click "Next."
4) In the "Connection:" drop-down menu, you should see "USB-PIN: UNKNOWN". Click the "Next" button.
5) You should then see a list of applications ready to be installed for your Blackberry. Hit Next and Finish and you are well on your way to getting your Blackberry back to life. Congrats! Just don't disconnect anything and let the lengthy process finish completely.
NOTE: If you do not see a list of applications mentioned in step 5 and instead see the message "The Blackberry Desktop Software does not have Blackberry Device Software for the device that you have connected to the computer. Contact your wireless service provider or system administrator," then you must download Blackberry's Operating System for your carrier and device. BlackBerry Software Download Site
Just select the appropriate carrier and network type, select your Blackberry model from the list and download the latest version. Install this download and follow the above steps again and you should be on the right path.
Good luck.

My Mac Mini won't start. The Power light blinks continusly (not pulses)

My New Mac Mini won't start up. I bought it online from J&R a week ago. My monitor says "no input detected" and the power light blinks. I recently fed it the gray mac os x install disk one, which it won't give back. Holding the mouse button when it turns on doesn't have any effect. So now i can't put a disk in or start it up.

Welcome to the Apple discussions.
No video with the power light blinking once per second means either bad or no memory. See this Apple note: http://docs.info.apple.com/article.html?artnum=303083 . Specifically, below is from that note:
If the computer detects no SDRAM (Synchronous Dynamic Random Access Memory, also referred to as RAM) or the RAM installed does not meet the appropriate specifications, the screen will remain black but the power LED on the front of the computer will blink once per second to signal the error. This error condition may be due to physically damaged RAM, installing the incorrect type of RAM, or not having RAM installed.
Has it ever worked since you got it? If not, you should call J&R and tell them they sent a dead on arrival system, and ask for a replacement (ask them to send a will call tag or prepaid label to send the non-working machine back).

Have 2 airport extreme base stations connected in chain. Airport utility shows slave unit without power. However, power is on slave unit, but status lights do not show up at all. Small green lights at each back port blink. Anyone have any ideas?

Unfortunately, you are describing the symptoms of an AirPort Extreme with a failing (or failed) internal power supply.
As a last resort, try a Factory Default Reset on the AirPort Extreme as follows:
Power off the AirPort by pulling the power cord
Wait a minute or two
Hold in the reset button first, and keep holding it in for an additional 8-10 seconds while you simultaneously plug the power back into the AirPort
Release the reset button and allow a full minute for the AirPort to restart
Now try to configure the AirPort again. If you continue to see the same symptoms as before, the AirPort will need to be replaced.

Hi,
I purchased Huawei Dongle and trying to connect with my new MacBook Pro (OS- Mountain Lion) USB port 3.0 but unfortunately it does not support.
When I plugged in my macbook the power is flowing in dongle due green light blinking twice in every 3 sec but no connection found or diver shown.
Please let me know how I have to use it. I got some suggestion for USB hub 2.0 but It does not make any sense and driver installation.
So please suggest proper direction to use it and provide link to install any driver.
Thanks
Tauheed Ahmad

Yes Clinton I did same, but they were (Huawei customer support) surprised about this problem, They behave like they have no idea about USB 2.0 and 3.0 knowledge. They handsUp that reason I posted my problem in this forum.
So is there any better solution to use any mediator between these USB version handling, Please let me know.
Thanks
Tauheed

HP 8510p laptop won't power up, lighting bolt light blinks six times and off.
Blank/black screen, fan/disk not moving. Nothing happen other than the light blinks and off.
Same problem for battery powered; battery + power adaptor or power adaptor only.

Hello tianhuat. I understand you're having some problems getting your notebook to power up. Try the following.
Remove the battery and AC power from the notebook.
Press and hold the power button for 20-30 seconds. This discharges the capacitors on the motherboard.
Replace battery and AC power.
Try to boot the notebook and post the result.
Are you also getting a blinking CAPS LOCK or NUM LOCK pattern?

Sometimes I cannot get my apple tv to work after being in sleep mode. I then have to turn the power on and off to make it work. Note the white light will come one when I try and wake it up. But, the light will not blink.

Most of the time when I wake up my apple tv, the white light will come on, but will not blink when I have this problem. I then have to pull the plug and then put the plug back in the socket, then it will work.

How long have you had it? If it is still under warranty, you can have Apple help you out completely. If it is not under warranty, Apple might still be able to send you articles to assist you in this manner. Check "Contact Us" on any page at the bottom.

Took apart Macbook pro 13 to remove broken headphone tip in the jack. Had to remove battery to get to the headphone jack. Now the laptop won't start. The power button is just not responding. Battery indicator showed charge of 3 dots initially but now only the last dot is blinking. The power cable used to light up green initially but now the green light is gone. I have tried SMC reset, which didn't work. What are my options?
