Try resetting the SMC
Before Resetting the SMC Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
  1. Press Command + Option + Escape to force quit any application that is not responding.
  2. Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
  3. Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
  4. Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
If your Mac appears to be running normally but isn't responding, force the computer to shut down by pressing and holding the power button for 10 seconds. Note: You will lose any unsaved work in any open applications.
For Mac portables experiencing issues related to the MagSafe power adapter and/or battery, try:
  1. Unplug the MagSafe power adapter from the Mac and the wall power socket for several seconds.
  2. Shutdown the Mac. Physically remove and re-insert the battery (if it's removable) and startup the Mac.
If the issue is still not resolved after following the troubleshooting items above, an SMC reset may be necessary.
After performing normal troubleshooting, these symptoms may indicate that an SMC reset may be necessary:
Fans
The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.
Lights
The keyboard backlight appears to behave incorrectly (on Mac computers that have this feature).
The Status Indicator Light (SIL) appears to behave incorrectly (on Mac computers that have an SIL).
Battery indicator lights, if present, appear to behave incorrectly (on portables that use non-removable batteries).
The display backlight doesn't respond correctly to ambient light changes on Mac computers that have this feature.
Power
The computer doesn't respond to the power button when pressed.
A portable Mac doesn't appear to respond properly when you close or open the lid.
The computer sleeps or shuts down unexpectedly.
The battery does not appear to be charging properly.
The MagSafe power adaptor LED doesn't appear to indicate the correct activity.
System Performance
The computer is running unusually slowly although it is not experiencing abnormally high CPU utilization.
Application icons may "bounce" in the Dock for an extended amount of time when launched.
Applications may not function correctly or may stop responding after being opened.
Video
A computer that supports target display mode does not switch into or out of target display mode as expected.

Imac intel 1.83 core duo 2gb ram ,doesnt restart from the desktop screen only by holding the power button.


I assume you mean you want to shut it down if you are expecting the fan to stop. In OS X you need to click the Apple symbol top left and choose "Shut down..." or "Sleep". If you need to force it to shut down (DONT DO THIS ALL THE TIME) then press and hold the power button for more than 5 sec till you hear/see it stop working

Restart off


4.4 Restart Feature
If a fault occurs in the machine, the diagnostic system will detect it. However, instead of displaying
a fault code immediately, the machine will try to restart. If the fault was only of temporary nature,
the machine will restart and finish the cycle. If there is a continuous fault the machine will try to
restart a number of times.
This process could take up to 8 minutes depending on the type of fault. After this, if the machine
still cannot restart, the fault code is displayed and the machine will beep continuously. The number
of retries will depend on the fault that it has detected, however the maximum number or retries for
any one fault is 32 times.
The restart feature is turned on when a machine leaves the factory. For servicing we strongly
recommend that this feature be disabled.
To turn the restart feature on follow the procedures below:
1. Enter diagnostic mode (Refer to Section 4).
2. Press WATER LEVEL DOWN so that the low water level LED is lit.
3. Press POWER to turn the display off (the 5 leftmost wash progress LEDs will be flashing).
4. Press POWER to turn the machine on.
5. The machine can now be tested on any cycle.
To turn the restart feature off, either repeat the steps above or switch off the power to the machine.
The restart feature can be permanently programmed in to the machine's memory. When in
diagnostic mode press and hold ADVANCE down at the same time as pressing WATER LEVEL
DOWN. A long beep will acknowledge the setting has been retained in EEPROM. Press POWER
to retain selection as with size switching. To remove from the permanent memory, repeat the
above procedure.
Note: This feature is designed as a service aid only and should be left on in the customer's
home. To return to normal operation, and to reset the restart feature to the factory setting,
switch the machine off at the wall or disconnect from the mains supply.
4.5 Recycle Feature
The recycle feature, when enabled, will cause the machine to continuously repeat the cycle that
has been selected. At the completion of the spin cycle the machine will power off briefly then
power back up again and will start the cycle programmed.
This feature would be useful to help identify an intermittent problem, and would be best used if the
machine had been taken back to a workshop for service.
To turn the recycle feature on follow the procedures below:
1. Enter diagnostic mode (Refer to Section 4).
2. Press WATER LEVEL UP so that the Medium water level LED is lit.
3. Press POWER to turn the display off (the 3 rightmost wash progress LEDs will be flashing).
4. Press POWER to turn the machine on.
The machine can now be tested on any cycle.
Note: This feature is designed as a service aid only and should be OFF in the customer's
home. To return to normal operation, and to return the recycle feature to the factory
setting, switch the machine off at the wall or disconnect from the mains supply.

Amp protection mode


Disconnect everything from the amp except the power cord, then power on the amp. If the receiver still shuts down, your problem is inside the case and unless you can perform electronic repair yourself you will probably need to take it in for service. If it does not shut down with nothing connected, power it off, connect one speaker or component and power on again. Repeat the process until the amp shuts down and you may have found the bad speaker or other component.

WHAT IS THE RESET BUTTON ON THE BOTTOM SIDE OF MY COMPAQ PRESARIO 2500 SPECIFICLY DO. IN OTHER WORDS IF I PUSH IT WILL I LOSE ALL MY STORED INFORMATION ON THE DRIVE?


This is straight from the manual:

Occasionally, Windows or the notebook might stop responding, so that you cannot turn the notebook off. If this happens, try the following in the order listed. Press the power button to restart.
• If possible, shut down Windows: press ctrl+alt+del, and then select Shut Down > Restart.
If the system will not allow a software shutdown, press and hold down the power button until the display shuts down (about 4 seconds) and then release the power button. Press the power button again to restart.
• Use a ballpoint pen or a straightened paper clip to press the reset button on the bottom of the notebook.

In other words: You will not loose any saved data if you reboot your laptop this way. All unstored information (open documents etc.) might be lost though.
