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

Installed the update tonight and now my phone (Lumia 928) won't power up. I've tried a soft reset, but the screen goes from the Nokia logo to a red Verizon screen to a black screen. What's wrong and how do I fix it? Help!

Installed the update tonight and now my phone (Lumia 928) won't power up. I've tried a soft reset, but the screen goes from the Nokia logo to a red Verizon screen to a black screen. Tried it 10 times with the same result. What's wrong and how do I fix it? Help!

Oh no Mr.Ected!
I can see if we can get your phone back on! I understand how important it is to have a phone. Have you tried this to see if we can get it back on? http://vz.to/1DZhteH . If it is still goes to a red Verizon screen and then to black we might need to do a master reset. While the phone is off try this:http://vz.to/1DZhXkU Be mindful this is the last resort because it will erase everything on the phone. If you have done back up assistant in the past you will be able to get you contacts back. Please let me know if you need any more help.

Nano won't power on, but shows up in My Computer and iTunes

I recently replaced the screen in my Nano and for about a day it worked fine. Then I opened it back up to clean off a smudge and now it's slightly less than functional.
First off before anyone asks, I use a PC, not a Mac. I run Windows XP Home Edition. And my iTunes version is 6.0.4.2.
Now my problem...
When not connected to my computer the device is useless, it won't power on, the wheel is unresponsive, no sound comes from the headphones, it's dead.
But when I connect it to my computer it shows up in My Computer and in iTunes and all of my songs show up and I can double click them and play them, but the screen on the Nano still remains dark and the wheel still does nothing.
Another strange thing is that My Computer and iTunes will only recognize it when I turn "hold" on. If hold is off it refuses to show up at all.
I downloaded the latest iPod software and it stopped showing up at all, so I uninstalled that and reverted back to whatever version I have now. I've tried to let it charge for 24 hours, that did nothing. I formatted it and let my computer re-install it's system files and what-not, that did nothing. I've tried to reset it, nothing. And I've mashed all the buttons and circled around the wheel endlessly to no avail.
I really have no clue what might have caused this or how to fix it, if anyone has any suggestions I'm willing to try them, because at this point it can't get that much more broken.
So um, thanks for any help. If anyone actually manages to help me fix this thing and you have a PayPal account I'll toss you like $20 or something for your time, because it's cheaper than buying a new Nano.

Wow. I have no idea, I have never opened my ipod to do any do-it-yourself repairs. Of course (as you probably already know) your warranty is now voided since you opened it up and made alterations to it.
I wouldn't know where to start troubleshooting this, as I am unclear as to the cause of the issue.

I have bought the wireless keyboard for my iPad. I was working for a day but now the power light won't stay on and as such won't connect to the iPad. I have changed the batteries but still no difference.

Not knowing which wireless keyboard you bought, it is difficult to be specific. but ...
it is quite normal for the keyboard's power light not to stay on - it is a way of conserving battery power.
Try this:
turn you keyboard off
on your iPad go to Settings > Bluetooth
if your keyboard is listed under Devices, then touch the little blue i to its right and choose Forget this Device
now reset your iPad: hold both the Home and Power buttons down for about 10 seconds until the Apple logo appears, let go promptly when the Apple logo appears and wait another 30 seconds for your iPad to turn itself on
After your iPad is back on again go back to Settings > Bluetooth
now turn your keyboard back on and see if it appeard under Now Discoverable
if it doesn't read your keyboard guide to figure out how to put it into Discovery mode
touch the listing for your keyboard under Now Discoverable, it should now appear under Devices
touch the listing for you keyboard under Devices, and choose to pair with it.

IPod screen illuminates but no image; iPod won't power off

iPod hard drive whirrs and screen illuminates, but no image (text or other) appears. iPod won't power off. iPod is recognized by iTunes only when in disk mode. Multiple restores were useless in restoring the screen function. Tools such as Disk Utility and Disk Warrior verified the directories were satisfactory. Can't locate a hardware diagnostic tool that can diagnose an iPod; and because the screen is malfunctioning, I can't run the iPod's built-in diagnostic routines.
Any solutions, or is this iPod destined for the repair shop?

If your iPod will not power off, unplug it from any power supply and wait for it to run the battery down completely. Then it will power off simply because there is not enough power to keep it running. (It may take 24 hours to do this.) Once this has happened, plug the iPod back into your computer. After about 30 minutes, you should see the "Please wait, very low battery" message. After a while longer, the iPod will have enough power and should reset itself. If not, re-post, but see below.
At the bottom of your post you state that you have a 30GB video iPod. In that case, if you need to re-post, it would be better in the 5th generation iPod forum, (either 5th generation or 5th gen late - see http://support.apple.com/kb/HT1353 for more information) as there will be posts from owners of the same model as you have, and with the same problems.

G5 won't power on but light is stuck on!

Hi
Today the power in my flat was turned off at the mains after there was a flood in my buildinbg - this happened while my G5 was on. When the power came back on at the mains, I found that the G5 white power light was on at the front, but nothing else happens.
Holding the power button doesn't turn the G5 on or off. It is just stuck with the power light on.
What has happened? Did the mains tripping off blow a fuse or something inside the G5 or is there something I can do to get it to reset? Or is it something worse?
Thanks for your help.

This is truly strange. I'm having the exact same problem. Last night we had a huge lightening storm here, and I powered down the computer, turned off the battery backup, and pulled the plug on the battery backup from the wall socket. After the storm, I reconnected and have exactly the same problem - power light constantly on, but the computer won't power up.
I was looking to start my own thread, but saw this and I guess it makes more sense to join in here. The only difference in artificedesign66's story and mine is that there was no sudden loss of power, everything was shutdown properly. It seemed to be running fine until that point, and did have an APC battery backup/surge protector in place for what that's worth.
I unplugged and replugged a few times last night. When that didn't work, I disconnected everything from the computer (monitor, all usb and firewire, power) and left it that way overnight. This morning I reconnected only the monitor, keyboard/mouse, and power, but still no go.
I do use a third party keyboard that lacks the power button - I use the one on the face of the cpu. Is there any value in digging the apple keyboard out of the basement to try that?
Thanks all for any help and to artificedesign66 for sharing the thread - hope you don't mind.

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.

Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

MacBook pro won't power up! Acting asleep, black screen, fans don't fire up. Light nr catch pulsing, have taken batt out and reset but still blank screen, help!!

You may want to try this.
Solution A
Start up your MBP while pressing Option (alt)|, Command, P, R until your hear 3 chimes rather than 2 as indicated by apple. This worked for me the first time.
Solution B
Start your MBP while pressing Option (alt), Command, S
Hold until you see the computer automatic routine. When it finally stops type the following followed by "return":
fsck -fy
It will probably indicate some problem related to "pcscd.pub" (should be 16 instead of 17). I haven't figured out what this means but somewhere in the Internet i read it is related to scan cards...
More importantly this routine will fix any problems with your HDD similarily to disk repair. When it ends, it will tell you if it has fixed/modified anything. If it has, run the routine again by typing again "fsck -fy"
Lastly, reboot by typing "reboot" (followed by "return")
Solution C
Start up your MBP while pressing option (alt), command, S
hold keys until you see computer commands scrolling
when the routine stops type the following, each line followed by the "return" key:
mount -uw /
chmod 775 /
chmod 1775 /
reboot
After which your computer should reboot on it's own.
Each of the above has worked for me at one time or another. Once your computer has rebooted from the DVD you can reinstall OS X. If your problems started after installing 10.5.6, then I don't suggest updating until 10.5.5.
I'm very very disappointed with my 2007 MBP, it started to give me problems after 1 year. had to change the HDD and lately when I isntalled 10.5.6 it suddenly refused to start up., My previous Mac laptop (2003 866Mhz) worked for 4 years without a hitch. Ironically I've had to use it to access the internet and find solutions for my current MBP.
best of luck
