MacBook Pro cannot be switched on

[yamashita]

I have a MacBook Pro (15-inch, Late 2008) that can't be switched on.

The battery indicator indicates full charge and the led on the magsafe connector is green. When I press the power button, nothing happened (no fan spin-up) and there isn't any display on external LCD as well.

I reset the SMC using Shift-Control-Option as well.

Anyone with similar issue too?

I believe you have the removable battery MBP?

There's a different step to reset the SMC for those: Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support

Resetting the SMC on Mac portables with a battery you can remove

Note: Learn about removing the battery on MacBook and MacBook Pro.

Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.
Remove the battery.
Press and hold the power button for 5 seconds.
Release the power button.
Reconnect the battery and MagSafe power adapter.
Press the power button to turn on the computer.

If possible do an NVRAM reset as well.

Worse case scenario, the logic board is dead.

Thanks, I did try that with no success in reviving the macbook pro.

I suppose it's not economical to repair the logic board of a dated macbook pro like mine?

It could be other parts like the battery. Have you got the battery replaced before?

The macbook pro can be used without battery connected as long as it's connected to power source via magsafe.

I had removed the battery and connected the macbook pro to power source but to no avail.

Where did you get that information from? Unibody MBPs requires the battery to start up actually. If your battery is totally dead, it will not start up.

I have a spare battery(15" MBP Late 2008) if you want to test, drop me a PM.

My battery was bloated and I sent it for RMA previously. For 1 week, I was using my macbook pro without battery.

Anyway, extracted the below text from some forum:

If the battery is removed from a MacBook or MacBook Pro, the computer will automatically reduce the processor speed. This prevents the computer from shutting down if it demands more power than the A/C adaptor alone can provide.

Thanks for the offer, I just ordered a iMac 27" Retina, once I settle down, I hope I can count on your help.

If you can switch the Mac on, yes the battery can be removed while it's on to run off AC power.

But to start up the Mac, the battery is required to power it up.

Bloated batteries are usually still functional.

Like I said, the battery was sent for RMA and for a week, I was travelling between locations using my Macbook Pro without battery, plugging directly to power source.
