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:

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.

There are two options you have. You can either acquire an OS (Operating System) disc to reformat the drive and reinstall the OS or you can return it to first user using the Single User boot mode.
The first option is easiest and erases their data so you don't have to worry about it being there.
The second option requires knowing some basic terminal commands.Final note: Have you tried just pressing enter on the login screen? Many times people don't have passwords but it will still ask for them.

Follow the steps below and it should solve your mac problem..

  1. Disconnect any devices connected to the computer including printers, hubs, and third-party keyboards or mice, and test the computer again by trying to turn it on.
  2. If you're using a MacBook or MacBook Pro, check the battery level. Press the small button on the battery or on the side of the computer. You should see lights indicating the battery's level of charge. If you see just one light blinking, the battery needs to be recharged. Use the fluorescent pen computer with the adapter connected to recharge the battery.
  3. Unplug the power adapter from the electrical outlet and from the MacBook, MacBook Air, or MacBook Pro. Wait one minute. Plug it back into the wall first, then to the computer. Make sure the electrical outlet is working by plugging in another device (such as a lamp). When you plug the adapter back into the computer, the PowerBook G4 Battery 15" power adapter LEDs should light up green or amber.
  4. Inspect the MagSafe port on the computer for debris, such as metal stuck to the magnet in the port, which might prevent the connector from seating properly. On the adapter side, look at the DC connector for dust or other debris and check whether pins are missing, bent, or stuck down. If you find any of these to be true, see Apple Portables: Troubleshooting MagSafe adapters for instructions on cleaning the adapter.
  5. Make sure you are using the adapter that was designed for your computer. If you aren't sure or if you need a new adapter,learn which adapter is appropriate for your computer.
  6. Press the control key, the command key, and the sony vgp-bps13a/b battery power button simultaneously and hold for three seconds to try to restart the computer.
  7. Reset the PRAM. After pressing the power button, hold down these keys simultaneously: Command-Option-P-R, until you hear the startup chime at least one additional time after the initial startup chime.
  8. Reset the SMC for the MacBook And MacBook Pro by removing the AC power, removing the sony vgp-bps13 battery and then holding down the power button for five seconds. On the MacBook Air, press (left) Shift-Control-Option along with the power button once. Note: You must use the keys on the left side of the MacBook Air keyboard.
  9. If you recently installed additional memory, make sure it is correctly installed and is compatible with your computer. Remove the new memory to see if the computer starts up properly without it.
  10. If you are still unable to start up your computer after trying each of these steps, schedule a service appointment with either an Apple Retail Store or an Apple Authorized Service Provider.

My apple laptop MacBook 13 has a message on the screen that is prompting me to enter a username and password. I have never set up a username and password so how do i bypass that page? or what can i enter...

Apparently someone gained access to your Macbook and enabled the password login feature of the operating system.
The login window that is displayed has a button for "Forgot Password". Click this button to see whether the person that set the password lock provided a cute hint for the password.

If they did not provide a hint, I would question anyone that has recently had the opportunity to access your Macbook to see whether they set the password lock. They would have the password.

Problems starting laptop

Your first recourse is to reset the power controller. Since I don't know the exact model and vintage of your MacBook Pro, I will post the reset procedure that applies to most of them.
  1. If the computer is on, turn it off.
  2. Disconnect the power adapter and remove the main battery.
  3. Hold the power button down for five seconds, then release.
  4. Install the main battery and connect the power adapter.
  5. Press the power button to restart the computer.
If this does not solve your issue, your machine will need professional service.

Macbook wont start

hi bobbie,

The only reason to pull the battery is to reset the SMU (used to be called the PMU). Do this when it's unplugged and completely un-powered, hold down the Start button for at least 5-7 seconds (count slowly) and then re-energize (battery and AC usually).

Also try zapping the PRAM (restart, holding down Command/Apple, Alt/Option, "P" + "R" (all four at once) and repeat until you hear start-up chimes at least 3 times. These may not fix it, but won't hurt.

The flashing question mark indicates that it's not finding the OS on the hard drive. In my experience, this usually means a re-install of the OS. If it's still doing this after the first two step above, dig out your install DVDs and get started.

Starting with the alt (option) button should put you into the Boot Manager. The password should typically be the the password for your (hopefully Admin-enabled) user account. Did you set the Master Password in the System Preferences? If so, you're back to erasing/starting over. If you use powerful features like this, select passwords you can remember, or write them down and store them securely (NOT a Post-It™ taped to the bottom of the MacBook or penciled in on the bezel - yes, I've seen both).

If I can be of further assistance, or if you have questions about any of my response(s), please let me know before rating me.

If this solves the issue, please rate it accordingly. My goal is to earn a "FixYa" rating from everyone I help.

Thanks for using,
