I suppose you have a l&te 2010 Macbook Air... - Plug the Macbook Air to a power outlet
- Plug the Macbook Air USB software reinstall drive that came with your Mac (in the little black cardbox) in any USB port - After the initial screen, go to "Utilities" in the menu bar and then choose "Reset Password" - Follow up the process and you should be OK.
Hope this will help. Cheers.

Laptop Toshiba Satellite A200 Model No. PSAF6A-02C01N fail boot


Try removing / swapping / reseating the memory.

Try booting with one stick only, if the top slot doesn't work, try booting the bottom slot. Try both sticks.

Let me know what happens.

My MacBook don't start. Is the power button? Is any password to solve this?


A password would not prevent your Macbook from starting, so I don't think that is the issue.

There are several variables to consider when it comes to power issues with an Apple Macbook.
For one, is your battery charged where you can test it without the MagSafe adapter, to see if the Macbook will start up?
• Also, is the MagSafe Adapter itself, not frayed or damaged, is free of debris and is able to connect securely to your Macbook?

If you have checked both of these sources for powering up your Macbook and you still cannot turn your Macbook on, then that is a hardware issue.

Sources of hardware issues with your model of Apple portable notebooks are:
* The Power supply: (source of power to the main logic board in the Macbook, and connects to the MagSafe port which of course connects the MagSafe adapter into a external power source - i.e: "a wall power socket")

* The Main Logic board: the main board in your Macbook which contains all processors, RAM, audio & video ports, ethernet, USB and other ports and components-including the Power Supply.

* RAM- If your RAM (Memory) goes bad, this can also impact the start up of your Macbook
---------------------------------------------------------------------
A good way to test and see if you can start your Macbook up is to try this procedure below:

-SMC RESET-
The System Management Controller is an integrated circuit (computer chip) that is usually on the logic board of your Mac computer.

It is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

• If the computer is on, turn it off.
• Disconnect the AC adapter and remove the
computer's battery.

• Press and hold the power button for 5 seconds
and then release the button.

• Reconnect the battery and AC Adapter.

• Press the power button to restart the computer

**IF you cannot get you Macbook powered up using this SMC Reset, that means you will need to take your Macbook in to your local Apple retail store Genius bar or Apple-authorized service center to have a diagnostics performed on your Macbook.

I am sure this will help guide you in the right direction toward address this issue.
Let me know if you have more questions regarding this issue.

Thanks!

Macbook will not power on. It's not the battery according to the Genius bar technicians


I assume it doesn't power on from the AC adapter either?
If not, perform the following steps:
  1. Disconnect the AC adapter and remove the computer's battery.
  2. Press and hold the power button for 5 seconds and then release the button.
  3. Reconnect the battery and AC Adapter.
  4. Press the power button to restart the computer.
If it doesn't restart, you have logic board issues, and need to bring the machine in to a service tech.

Macbook goes to sleep and doesn't wake up unless I do a hard reboot.


I have seen this caused by having a mouse plugged into mine. I have removed the mouse and touch the touchpad and it has come up from sleep.

That very well may not be your problem.

Here is the procedure that is recommend from Apple to help with the not waking from sleep problem. I included both methods as it is not clear which macbook you have. I also included the link to the article at the bottom.

The System Management Controller is an integrated circuit (computer chip) that is on the logic board of the computer. As the name implies, it is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

Over time, the settings in the System Management Controller may become unusable, which can result in operational anomalies with the computer. Examples include not turning on, not waking from sleep, not charging the battery, or not recognizing the AC Adapter, among others.

MacBook (13 inch, Late 2008), MacBook Pro (15-inch, Early 2008), and MacBook Pro (17-inch, Early 2008)
  1. If the computer is on, turn it off.
  2. Disconnect the AC adapter and remove the computer's battery.
  3. Press and hold the power button for 5 seconds and then release the button.
  4. Reconnect the battery and AC Adapter.
  5. Press the power button to restart the computer
Note: Starting with MacBook Pro (Late 2008) and MacBook (Late 2008) models, you may instead use the reset method for MacBook Air (below) to reset the SMC. All earlier models of MacBook and MacBook Pro must use the method described above, which involves removing the battery.
MacBook Air and MacBook Pro (Late 2008 and later)
  1. If the computer is on, turn it off by choosing Shutdown from the Apple () menu.
  2. Connect the power adapter to a working power source.
  3. On the built-in keyboard, press (left) Shift-Control-Option along with the power button once.
  4. Wait 5 seconds and press the power button to start the computer.
Note: You must use the keys on the left side of the built-in keyboard.
