When i press power button i hear several click sounds before start up?

When I press power button I hear several click sounds before start up begins. Shortly after Apple logo appears it clicks off.

Which MacBook Pro do you have? If it has an optical drive then that is just the optical drive checking if there is a disk inserted.

  • Crash when I press power button?

    When the computer is on and running, and I press the power button (to shut down or standby), the computer immediate freezes up and seems to stay that way.
    Has anybody else seen this?

    Would be very curious to hear from other Air users. When you press the power button, does your Air freeze up? Or does something else happen?
    On my (rev B, 128Gb SSD) Macbook Air, pressing the power button does what it does on my other Macs, which is to immediately pop up a window with "Are you sure you want to shut down your computer now?" and buttons for "Restart", "Sleep", "Cancel" and "Shut down". Selecting any of these buttons does what you'd expect.
    I've not heard of this issue before either. On the two Macbook Airs you can reproduce it on, do you have any software (particularly any sort of enhancing, system-utility sort of thing) that I - or most other Air users - would be unlikely to have? In my case mine is just normal OSX 10.5.6, with all patches, etc up-to-date, iWork 09 is installed as well as the XCode development tools. No system-level "enhancing" sort of software at all. Do you have anything connected via USB when this is happening? Anything logged in the "all messages" query in Console at the time you've pressed the power button? Are any processes doing anything badly-behaved all the time (ie does Activity Monitor show a runaway process) and you're only noticing the bad effect when the bit of code that does the popup window on the Power button press tries to run?

  • Macbook pro is not getting turn on and further when i press power button the green orange light suddenly changes to green again, moreover battery meter is not working

    Hi
    Last night my macbook pro gets off automatically when battery gets empty and in the morning it isn't turning on. When i connect the charger, the light on the charger turns green to orange (showing that it is charging) but when i press the power button it suddenly changes to green again. I thought there must not be any connection between the charger light and the power button. And battery meter was running fine.
    When it tried this again and again the charger light disappear and battery meter also stops working, when i clearly observe it there is a very dim green light in the charger (not observable in the light) and the laptop is still not showing any change.
    please help!

  • Can't boot iMac, problem started after loading OSX. When I press power button I see Apple logo, twirl and a bar. Looks like is loading but after few seconds it shuts it self off

    I can't boot my IMac. I loaded OSX and first mail then contacts start acting up.
    I shut down and now the iMac won't boot. When I press the power botton it comes on, I see Apple logo, swirl and a bar which saw loading for a few seconds and then shuts it self off.
    HELP!

    Try an SMC reset first, and if that doesn't help, follow up with a PRAM reset:
    https://discussions.apple.com/docs/DOC-3603
    If you're still having problems try a 'Safe Boot' - restart holding down the shift key until you see a grey progress bar. Once booted restart as normal from the Apple menu.
    If that doesn't work, boot into the Recovery HD, launch Disky Utility and check the Macintosh HD using the 'repair disk' option. If anything gets fixed click on repair disk again until you get a clean pass, then restart as normal from the Apple menu.
    To start into the Recovery HD restart holding down Command + r

  • My new HP Split X2 2 in 1 is not starting all the time when I press power button.

    I brought HP Split X2 2 in 1 (tablet com laptop)1one week back and I have the prob from day 1. Press the power button for 1 sec to 10 sec for 100 tmes a day, it is starting only once per day. No one knows at which attempt it may started it may be 10th or 50th or 100th. Certenly in the begining of the day it is not startng. If it starts by luck, then it works. After it start, even if u do a shutdown and restart, it works. But go to sleep and wake up in the morning, my attempts starts. Customer care talks to you politly but each time each member has diffrent solutions. Its a defective piece..
    Any suggestons would be appritated. It has 2 batteries, 1 in touch panel and the other in key board.

  • MacBook Pro crashes when I press power button to shut down

    Installed Lion (10.7.2) on a 2010 MBP yesterday; had to replace the hard drive as it failed the SMART test. Everything seems to be working fine until I press the power button to shut the computer down. It freezes solid every single time. I have to then hold the power button down for 10 seconds so it restarts.
    Anyone else with that issue?

    I reset the PRAM/NVRAM which, incidentally, is different than it used to be. No more chimes; instead a screen which allows you to run Disk Utility, which I did. Also repaired permissions.
    I reset the SMC which I thought would solve the problem considering the power button is managed by it. No luck.
    I've disabled the tablet extension because I'd seen an error mentioning it somewhere and I've updated Growl to 1.2.2 although not the new Lion-friendly 1.3 because people seem to have a lot of trouble with it. Still, it's an option.
