Last night i used my mac ibook i used the wi-fi and then when im already through i press the power button then it appears a message saying that "are you sure you want to shutdown?" then i press yes. then the other day i want to used my mac again i turned it on but it seems that it doesnt turned on. anyone can help me what seems to be the problem?
i already fully charged the battery but there seems to be no solution. i removed the battery and wait for about an hour and insert it again but it wont work to.
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 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
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

enable you to access a secure Wi-Fi network.
If you are connecting to a secure Wi-Fi network with MAC address
restrictions, you will require pre-authorisation for the router. You
will need to find your Samsung Jet's MAC (Media Access Control)
address. This is a 12-character code which may be needed by the network
controller to enable the phone to connect. See Getting the Samsung

Make a note of the MAC address. You will need it if you want to use
the Samsung Jet's Wi-Fi to access a secure Wi-Fi network using MAC
address restrictions. This can be added into the wireless router
settings access list.
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
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.
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.
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.
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.
