Upon power up, the screen shows little smiley faces. I tried removing the battery, hard drive, and AC Adapter, pressed the power button for 15 seconds, then reconnected the AC Adapter. I get the same issue.

If a PC suddenly fails to boot properly, you should perform a hard reset as the first procedure.

1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds .
3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
4. if still there no sign of life then send it to nearest service centre

Please use an external monitor if necessary, and please do these:
1. Unplug the AC adapter,
2. Remove the battery,
3. Remove the hard drive,
4. Press the power button and hold it for 15 seconds,
5. Plug in the AC adapter,

Thanks for contacting Fixya Support, I am glad to assist.

What you need to do is perform an SMC Reset in order to allow your Macbook to start back up correctly to the desktop.

Here are the procedures for an SMC Reset:

-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 Macbook'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 Macbook

If this does not work, then try this procedure:

I am going to have you take your Mac into Safe Mode to see if we can't remove a possible folder(s) that may be affecting your Mac's start up function.

-SAFE BOOT MODE-
• Reboot your Mac
• Upon restarting your Mac, press the Shift key.
• Hold the Shift key until you see a White Screen with Gray Apple icon and eventually a spinning gear.
• When you see the Spinning gear, release the Shift key.
• Allow the Mac to continue booting up. Also this may take a little while.

(NOTE: this may take anywhere from 5 to 15 minutes to load to the Safe mode screen depending on the performance of your Mac, but if it exceeds this time, shutdown your Mac and try just once more. It may have just frozen up the first time around for you.)

• You are going to enter the Safe Mode (which looks like your main desktop environment - the only difference is certain startup items are disabled.)

• Once within the Desktop in Safe Mode
• From the Finder Menu, click Go> Go to Folder
• Type in this line: /System/Library/StartupItems
• This path, is going to take you to the System Library folder which has all of your Mac OS X Startupitems.
• Remove all of those folders to the Trash.

*Reboot your Mac normally and see if you can access your normal User desktop environment.

Let me know if this helps.

I think it's the memory chips which should be causing this problem.

HAve your memory chips checked
