If you have the problem with no chime, no screen light up, and fans at max, it may be possible to fix it. It is often a design flaw in the soldering process.
Press firmly down on the left of the mouse pad when you press the power button (or try holding it in your left hand with your thumb by the touch mouse and fingers under the mac pressing firmly on the bottom) if it chimes. or even boots when this is done you can find a shop that does soldering(micro soldering) and have them fix the chip thats lose. Or for a quick fix try this site http://www.coreyarnold.org/ibook/ he shows the most common chip that comes lose.
All but 3 or 4 failed iBook's that had the fans start and nothing else, seem to have this problem(that I've seen) but Mac refuses to say it's a defect in all country's but Denmark (because a official study was done there that proved it was a manufacturers defect that each time you power on/off the iBook the solder gets a little looser.)

My iBook decided to (most of the time) not start, and then when it did start up, it would shut down at random intervals. I tried all the various key sequences, tried starting up with the battery, without the battery, all with no success. 
There was only one tip that I stumbled upon (can't remember where or who the poster was--many thanks to them!) that did work. 
1. Unplug the power adapter from the iBook. 2. Remove its battery. 3. Let it sit for 1/2 an hour to an hour. 4. Press the power button several times, as if you're actually trying to start up the iBook. Make sure you do this WITHOUT the battery and WITHOUT the power adapter! (Yes, I know there's no power source and it won't actually start.) 5. Replace the power adapter. Try to start the iBook with only the power adapter and no battery. If this works, then replace the battery as well.
From what I remember, what step #4 is supposed to do is drain all residual power (from capacitors maybe?) from the circuitry and forces the power management circuitry to reset itself. There's a key sequence that's supposed to reset the power management circuitry as well, but it didn't work for me (no matter how many times I tried it). My iBook now starts every time with no fuss.

I hope this helps someone out there!

I had the same problem. Did the fan turn on after about 5 seconds at full power? If so it is a logic board problem and will cost ~$300 to fix if out of warranty. If you paid with a credit card check to see if they offer extended warranty coverage. Thank god mine did, so i should be getting mine fixed. Good Luck.

Try these in no particular order (except last 3) try command-option power this puts p-books to sleep (may trigger it to wake) (it could be asleep) Remove your battery and wait 5-10 mins then try to start up with battery in Remove your battery and wait 5-10 mins then try to start up with battery removed To zap PRAM On startup hold down the cmd, option, p and r buttons Hold till you hear boot up sound To zap NV RAM On startup hold down the cmd, option, n and v buttons Hold till you hear boot up sound To reset the screen on a powerbook: On startup hold down the r button - To force internal Hard drive to be startup disk On startup hold down the r button - until boot Disable extensions: Try power up-reboot with shift key down Last but not least try to startup with original MAC system startup CD If all else fails try to get to an Apple Store...unless it's a real hardware problem (fried circuits/damage they'll fix it for free!) Pray - believe it or not... it worked for me when I got down on my knees and prayed. Hope this helps

My toshiba tablet wont connect to my wi-fi please help

1. Make sure that your wi-fi settings are turned on.
2. Scan for local wi-fi
3. Select your desired wi-fi and provide password if required.

Many times, the settings from the menu are not turned on, so the tablet will not try to link to a wi-fi site.

If you need more help, please provide the model number and the operating system currently being used on the tablet.

Describe your cannot start ibook G3Problem it simply does not start, battery is ok and I have tried to take the battery away and back in its place, but nothing what can I do?

Make sure your iBook is plugged in to the wall. Hold down the power button for a few seconds. If that doesn't work, try holding down Command (the Apple key)-Option-P-R (hold all four keys down) and press the power button. Be sure to hold the power button for a few seconds whenever you turn it on.

If that doesn't work, try resetting the Power Management Unit (PMU). This is kind of a "last resort," according to Apple. Don't do this all the time.
  1. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
  2. Wait 5 seconds.
  3. Press the Power button to restart the iBook computer.
If you have a very old iBook, you may have to unplug your iBook, remove the battery, and
  1. Press and release the reset button located above the Audio/Video port on the left side of the iBook (Dual USB) computer by inserting the end of a paper clip into the small hole and gently pressing the switch once.
  2. Wait 5 seconds.
  3. Reconnect the AC power adapter.
  4. Put the battery back in the computer.
  5. Press the Power button to restart the iBook computer.
(If it still doesn't start, do you hear the fans going?)

Good luck! Let us know if these steps solve your issue.

I cant connect my dell latitude d531 to the internet

Press the button just to the left of the power button (when mine turns on the bluetooth light appears just below the screen on the right side). See if it works now. If not, reboot, press the F2 key during startup (keep tapping until the message in the upper right goes to "Preparing to enter setup") to go into Setup. Go to the bottom of the list on the left side to Wireless. Hit enter to open the list, go down to Internal Wi-Fi and make sure it is enabled on the right side of the screen. Also, check the last setting and set LAN/Wi-Fi Auto Switch to Off. You might also have a bad wireless card or a bad driver. If nothing works then re-post as possible driver problem.

I purchased a new IPOD and I can not access the wifi from my Linksys wireless router.. I reset my Linksys router to try to solve this problem. And at first when the light was amber I was able to have...

Resolution If you know there is a nearby Wi-Fi network, but you are unable to locate it on the Settings > Wi-Fi screen:
  • Move closer to the Wi-Fi router or hotspot.
  • If you are using a personal Wi-Fi network, verify the Wi-Fi router is connected to power and turned on.
  • Wi-Fi networks configured as "closed" or "private" do not broadcast the network name to Wi-Fi devices.
    • Join a "closed" or "private" network by tapping Settings > Wi-Fi > Other and entering the Wi-Fi network name, security, and password.
After joining a Wi-Fi network, if you notice the signal strength is low or intermittent
  • Move closer to the Wi-Fi router or hotspot.
  • Check for any sources of potential interference.
  • Remove any cases or attachments on your device that could interfere with a Wi-Fi signal.
If you are unable to access the Internet while connected
  • If you are using a commercial Wi-Fi network that requires a special login or subscription, see this article for more information.
  • If you are in a location with multiple Wi-Fi networks, verify that you are selecting the correct network.
  • Verify that the Wi-Fi network settings are correct:
    • Tap Settings > Wi-Fi.
    • Locate the Wi-Fi network you are currently using and tap ts1398_2.jpg
      blank.gif
  • You can configure network-specific settings, including IP address, DNS, and Search Domain settings.
  • Use "Forget this Network" to reset settings for this particular Wi-Fi network, including the password. This is also useful if you identify a network issue and want to prevent the device from automatically using this network in the future.
  • Use "Renew Lease" to acquire new IP address, DNS, and Search Domain information from the Wi-Fi network.
  • Note: If the Wi-Fi network uses MAC address filtering, you will need to add the MAC address to the access list for the Wi-Fi router. The MAC address for your device is listed as the Wi-Fi Address in Settings > General > About.
If you are still unable to join a Wi-Fi network, or are unable to access the Internet while connected, try the following
  • Restart the device
    • Hold the power button until "slide to power off" appears. Slide to power off your device. When it is off, press the power button to turn it back on.
  • Reset network settings by selecting Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings, including passwords, VPN, and APN settings.
  • iPhone only: If you continue to experience issues, consider turning off Wi-Fi and using the cellular data connection instead of Wi-Fi.
Additional Information If using a Wi-Fi router at home, refer to your user manual/documentation to assist you with some of these suggestions.
  • Check the manufacturer's website for your Wi-Fi router for firmware or software updates.
  • Verify the Wi-Fi router can broadcast an 802.11b/g signal. If using a 802.11n Wi-Fi router, consult the manual/documentation for how to configure the Wi-Fi router for 802.11b/g compatibility.
  • If you are using multiple WEP keys on your Wi-Fi router, try configuring your Wi-Fi router to use only a single WEP key.
  • Try or resetting (or turning off and then on again) your Wi-Fi router. Note: If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
  • Disable wireless encryption or security on the Wi-Fi router to rule out encryption issues. If this resolves the issue, try using a different encryption or security protocol.

Hello- I have a ibook G3 running 10.3.9 and the wireless connection stopped. I changed out the air card, still nothing. Could this be a firmware issue, or a bigger hardware problem?

Try disconnecting the air card and pushing the wire back on it firmly.  Click on the wi/fi and type in your password.  Could be the little wire for wi/fi is broke.  Check Apple web site for updated drivers.  Update your OS to Tiger 10.4.11 if you got a new modem.
