Mac air giving a beeping sound and is not starting

I was working in the morning and kept it in sleep before i went to bath. After that when i again wanted to start my mac air its giving out a beeping sound and nothing else is working. Mac is not starting up

Did you do a complete shutdown? If so, and it's not starting up at all (no chime, dark screen) then it has died. Please make a Genius Appointment and take it in for service.

No beep sound and No signal

I tried to start my k450e, but there was no beep sound and no signal on my monitor. How can I fix this? I don't know what is the problem.... and should I visit the local warranty service providers??

Welcome to the Lenovo Community !
I am assuming that the computer is showing some signs of life such as the fan spinning or lights illuminated. If there isn't then check your power source. Try plugging the computer in a different wall socket.
If the problem still continues and you are not comfortable working inside your computer or your warranty is still active then I would recommend you contact Lenovo Support for additional assistance in getting your computer repaired or visit a local area Authorized Lenovo Repair Center.

Device get Automatically switched off and unable to turn on ...

Hi experts,
I wish u happy new year to everyone..
I am facing a critical issue in my bb torch 9860,device get automatically switched off and unable to turn on the device by switching the power button .after doing hard reset it turns on ....iam missing calls .please help me how to trouble shoot it

It's obviously a software issue so I suggest jumping right to an OS reload. Battery pulls are always a good place to start but after that you should reload the OS.
To do this, plug your phone in to your PC and open BlackBerry Desktop Software. Click Device at the top of the software then Restore. Choose the most recent restore point and load it.
Let us know if that helps you.

EMac won't start and 3 beep sound and light flash

My eMac suddenly got problem these days.
Last night, eMac can boot and login. Suddenly, the monitor cant display property. Then, i enforced to power off. Later, trying restart it. eMac cannot start up and breeze 3 beep sound and flash power light.
I checked support forum. It claimed that "3 beep - no good banks". Actually, i dont understand what it is. What i can i do??

KY18,
Welcome to the Apple Discussions!
The three beeps mentioned in Power On Self-Test Beep Definition means that during the startup test of RAM, the Mac detected that there are DIMMs physically in one or both sockets, but that neither DIMM is functioning electrically.
It's unlikely but possible that one RAM DIMM may have suddenly failed catastropicaly, far more unlikey if you have two DIMMs installed. A more plausible scenario, considering your mention of display problems, would be if the eMac were plugged directly into a wall outlet, or into a low-cost surge protector whose MOV hardware had degraded and failed (the status LEDs on low-end surge protectors are essentially worthless). If there was a power surge while you were using the computer, that could have blown out the RAM (and potentially damaged other hardware as well). Surch brownouts or surges are usually evident in the effect on room lights, clocks, and other elctronic devices plugged into the power outlets.
As a longshot, you can try pulling the RAM DIMMs and then reseating them in the slots, making certain that the thumb clips holding the DIMMs have snapped fully into place after reseating them. Check the RAM installation instructions at eMac - Do-It-Yourself.

Iphone 4 turns off randomly and unable to turn it on without charger

iphone 4 turns off randomly and unable to turn it on without connecting to charger or PC

Hey Tiffy6996!
I have an article here for you that describes this issue and can help you troubleshoot the issue a little further:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/ts2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks for coming to the Apple Support Communities!
Cheers,
Braden

Try reseating the graphics card and make sure the power connectors are hooked up.

Dropped my ipod and now it makes a clicking sound and won't turn on at all. is it cheaper to get a new one or fix this one?

i have tile floors and i dropped my ipod classic flat on its back while it was off. i tried turning it on after that and it now it makes a clicking sound and won't even turn on. all it shows is a dead ipod and told me to go to apple.com/support/ipod. i'm not sure how to fix it or if it's even fixable. or is it just cheaper to get a new one?

If the phone will not power on try these three things:
Connect it to your phone charger
Connect it to your computer and open up iTunes
Perform a hard reset (Hold down the sleep/wake (top) button at the same time as the home (circle) button for 45 seconds. When the apple appears on the screen let go of both buttons.

Wireless 3dTactic Rage - beeping sounds and cannot turn off . . .

For some weird reason i cannot turn off my headset anymore.
It doesn't work.
When i try, it simply looses connection with pc and reconnects. At least i'm guessing that's what's happening.
The USB transmitter is swithching between blinking and fixed light.
I've tried re-pairing it a few times now, that stops the connect/disconnect issue but i still can't turn off the power. . .
Unlike many others who are experiencing problems, i have NOT attempted to install any firmware updates, so i'm at a loss at what is happening here.
Any suggestions?

My mac is not starting and on turning on makes a beeping sound and the screen is blank

the operating system is Mac OS X Leopold

Beeping means RAM problem:
Intel-based Mac Power On Self Test RAM error beeps
Power On Self-Test Beep Definition - Part 2

What does it mean when my MacBook makes a clicking sound, and when I turn it off and back on again all I get is a folder icon with a ? in it?

My MacBook made a clicking sound. I turned it off for 5 minutes, then restarted it. Now all I get is a folder with a ? on it. Is my battery fried?

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'llsee a panel asking you to choose your language. Just press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

My iMac running 10.8.2 in sleep mode was repeating three beeping sounds and was unresponsive. I had to pull the power cord to restart. Now it appears fine. Anyone know what the three beeps means?

What does a three beep repeating sound indicate?

3 beeps generally indicates a ram problem. Mac computers: About startup tones - Apple Support
3 successive tones, a 5 second pause (repeating): This indicates RAM does not pass a data integrity check.
You say your iMac was beeping during sleep? Have never heard that before. Try removing and reseating the ram.
Reset the PRAM How to Reset NVRAM on your Mac - Apple Support
You might also consider running The Apple Hardware Test OS X Mountain Lion: Use Apple Diagnostics or Apple Hardware Test
You should also update your OS X About the OS X Mountain Lion v10.8.5 Update - Apple Support
Finally you don't use Chrome do you? There have been reports of beeping while using Chrome, don't know why.

I was out of my room for an hour and when returning, my computer was making continuous beeping sound and was unresponsive.

I am new to Apple, just bought the computer a month ago. I extraced this from the log file. I fear I've picked up some malware or been hacked...

If anyone can help me I would greatly appreciate it. Thank you in advance. I am on an Intel iMac 10.8.1

Since it's a new machine, contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine. That also might apply to newly bought ones inside the first 90 days.
FWIW, IMO, the AppleCare extended plan's the cheapest insurance you can get for your new desktop machine.

My iMac won't boot up, just makes a beeping sound and goes off. Any ideas?

Managed to insert diagnostic cd and got it to boot. Done scan and shows Video Ram, Volume Structure failed. Any ideas?

Make an appointment at your local Apple Store or AASP, it sounds like a hardware fault. You can begin booking the appointment using Apple Online Service Assistant.
