Can you tell us a bit more about your Macbook? How old is it and can you get the model off it? Do you know any specs?

Is the Magsafe plugged in and what color is the light on the Magsafe plug? Amber or Green? Battery in the Macbook?

Hi there, its about 4 years old, the white 1. 2.4ghz intel core 2 duo, 2gb . when i plug charger in the green light comes on the turns orange as per normal but no chime sound and just the noise of the fan running

It's hard to say but it could either be that your MagSafe Adapter charger unit is bad, maybe a dead battery, or lastly the input DC board in your MacBook has failed.

You can try removing the battery and just use the MagSafe Adapter charger to see if your MacBook will turn on that way. You don't want to spend too much money on repairing that model MacBook as it may not be worth it.

your macbook has failed time for a new logic board.

when the white MacBooks die they only get power to the fans and the cd drive and the hard drive because the graphics card has failed on the main board of which there is no replacement sorry

put your ear next to the macbook press the power button if all you hear is the fans and the hard drive powering up your logic board has failed

This may be a long shot…but just in case. Push the power button (or whatever you've been doing)…and if you hear the fan & the HD…take a flashlight & shine it on the display. See if you can see your MacBook's desktop.

You kind of have to do this at a sharp angle to see things the best (not straight on). If you can see "stuff"…then something to do with the display has failed. Also…you can test things by attaching an external display.

Of course if you see nothing…then what "johnodd4" mentioned could be the problem.

Long shot but try cleaning out both the mag adapter and where it connects to the Mac. My Buddy couldn't get his to work and what was going on was he had some metal shavings in the adapter that wasn't allowing it to charge correctly.

Once he cleaned it all up it worked just fine again.

thank you for all your replies, i will try the things mentioned and see what happens. is a new logic board expensive ? and does that mean i will loose everything on my macbook ?. i tried it again this morning by pressing the power button and nothing at all now, not even the fan etc. gutted

IF that is the problem, then yes it would be quite expensive. I presume it is not covered by AppleCare any more.

and does that mean i will loose everything on my macbook ?

Almost certainly not. The hard drive is unlikely to have been damaged by a logic board failure, and thus your data should be safe.

Take it to an Apple Authorised Service Provider or an Apple retail store and see what they say.

 

[johnodd4]

yep agreed but a warning if you have to purchase a logic board you would be better with a new macbook air or pro because a logic board for a white macbook is $800.00 and for 100.00 more you can honestly upgrade to a macbook air or for 300.00 more go to a macbook pro refurbished model direct from apple

Just to add my 2 cents. Yes...a new logic board would be wayyyy expensive for a 4 year-old MacBook. A new logic board for a 4 year-old MacBook will probably cost at least 2x the value of the MacBook.

For example...here's a working used logic board from powerbookmedic.com for $224.95. A new one would cost much more...and this is just the parts cost. If you needed to have someone install the logic board...factor in a bunch more $$$.
