Macbook unibody late 2008 model having trouble with the trackpad click. sometimes it works but most of the times it would not function

Did you try searching before asking? MacBook Pro 13 Unibody Early 2011 Battery Replacement

in the apple drop down menu there is a thing that says about this Mac. It will pop up a screen with some basic info, if you click on the part that says version it will show you the serial number. Cut and paste that info into google or go to a mac website that identifies machines by the serial number. Should be easy to find with a google search. Sometimes they give models like 5,1 or 6,2 etc. Sometimes you have to actually look and try before you can get the answer you want.

I have a MacBook late 2009 2.26 unibody. I had to find that out the same way I just described so I could find parts. You can also go to ifixit.com and see if that helps to id your machine.

lots of cable problems during that period. Most were covered by recall that was not published like the car recalls ... just handled as they were brought into the Apple Repair spots. Mine was replaced along with new case and new fan.

Hello,

Does it show even when the computer is still booting up?

Your macbook is upgradeable right up to OS X 10.8 Mountain Lion. Here's some good info to help you.

As the Macbook is under a year old it is still covered by a one year warranty unless you took out AppleCare so what I would do is take it back to an Apple Store or go to the Apple webpages and click on support and you will be able to arrange for it to be repaired. Hope this helps.

Try format your laptop if that's ur suspect in dis-abled keyboard. If not successful, maybe the controller chip of the keyboard is defective, or try other keyboard for ur laptop, go to laptop repairshop.

Do you mean the behind the keyboard backlight or something else?
As far as I'm aware only the macbook Pro models have KB backlighting so without a motherboard change you are probably out of luck

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.

I am running mac OS 10.5.5 and Win XP using parallels.  You need to make sure the system preferences in the mac OS to allow two fingers for secondary click using the trackpad. This allows you to right click in Win XP.
I find using two fingers and clicking the button works more reliably in windows xp.  I usually have to try two finger tapping a few times.

To right click by tapping: Go to System Preferences and choose Keyboard & Mouse.  Select "Clicking" and "Tap trackpad using two fingers for secondary click". This allows you to tap the trackpad with two fingers side by side to get the "right click" effect.  You can also right click without tapping with this setting.


To right click without tapping:
Go to System Preferences and choose Keyboard & Mouse.  Select "For secondary clicks, place two fingers on the trackpad then click the button". This allows you to right click by placing two fingers on the trackpad and then clicking the mouse button.
