Three beeps at startup almost always indicate bad RAM. You probably need to get your RAM replaced. Bring it in to Apple for a definitive diagnosis if you are unable to run the Apple HardwareTest

Mac Book Pro on boot up, the apple sign will appear with the spinning wheel. After a period of time the screen will turn grey, but the mouse will still operate, but not boot up.
If it was purchased brand new then it's running a version of Lion, so to reinstall Lion:
Reinstalling Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button. -
My mac book pro is working, but my power light is off, the battery power light is not on and my battery power symbol is a black x. My computer is making a whirring sound sort of like it does when loading a CD. I had a hard time getting the computer to turn on, used the command, option, P and R buttons to turn in on. I have tried restart, but I still get the whirring sound. What is wrong and what do I do?
Didn't do an SMC reset. But in attempting to find out about what that was I found some things to try first. Also, when I went to system preferences - hardware, I couldn't find anything regarding power and battery info. Finally, I unplugged the computer for several seconds, then shut it down, removed the battery, put the battery back in. Then I turned on the computer, plugged in the power cord. Problem solved- no whirring sound, battery charging light is on.
Thanks for getting me in the right direction. -

The back of the Ipod is warn so I can't see the serial number, so please let me know if you know anything that would help.

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Do you have to turn off your Mac book pro ?
Do you have to turn off your Mac book pro ?
Welcome to Apple Support Communities
If you aren't going to use your MacBook for days, turn it off to save battery. If not, you can leave it in sleep mode. Sleep mode doesn't consume a lot of energy and allows you to start up your Mac in seconds, being faster than turning on the MacBook, so it's better to leave it in sleep mode -

It's new and under warranty. That's the reason to go to the Apple Store.

Mavric doesn't support my 5 years old Big Screen Display, OR? Tried to connect my Mac Book Pro after installing Mavric, The Screen didn't work as before. I could only see the Desktop but not the movies for example.
<E-mail Edited by Host>It appears what happened is the installer though it was looking at a empty drive and just went ahead and installed.
I of course am assuming here you didn't use Disk Utility to format the drive first before installing, that would wipe out your files and programs for sure.
So what to do, what to do.
Well there is hope for you as long as the drive wasn't Filevaulted.
I'll explain. When a hard drive writes data for the first time to a drive, it starts at the very top and works it's way down.
When OS X was installed the first time, it was at the top of the drive, unless you upgraded then the upgraded OS X could have been written elsewhere.
Now when you just reinstalled OS X, the new OS went on the top of the drive, overwriting any data that was there previously, so what was there you have lost forever which is about 8GB or so. If it was the previous OS there, then your more in luck because only the old OS X was overwritten.
The remaining space on the drive still can have a copy of your files, provided it's not overwritten yet.
It's because when a hard drive deletes data or reformats, it doesn't remove the data off the drive or overwrites it immediately, it's just made so it's SPACE is available for new files to be written there.
So technically one can recover the deleted data off a non-encrypted/scrubbed hard drive with special software.
The way it does this is it reads the 1's and 0's of the files themselves, and through a lot of figuring out, can tell what that file is and what it belongs too.
So what you will have to do is this:
Create a data recovery/undelete external boot drive
or if you don't have the skills, then take it to a local PC/Mac tech and they can do a direct image of the drive and then you can run Data Rescue on it to rebuild your files. -
How can i connect my 2008 mac book pro to a tv?
how can i connect my 2008 mac book pro to a tv?
The Mini-DVI to DVI adapter is designed for the iMac (Intel Core Duo), MacBook, and 12-inch PowerBook G4 — allowing you to connect to an external DVI monitor. It can also be used in combination with the Apple DVI to ADC adapter to support older Apple flat panel Studio or Cinema Displays.

How can I connect my Mac Book Pro (year 2008) to the TV set through HDMI? I've seen a DVI to HDMI iwire but I'm no sure that it is correct. Could anyone help me? Thank you very much.
I do not know the iWire adapter, but I use an inexpensive ($3) DVI to HDMI adapter from Monoprice, along with a regular HDMI cable:
http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10419&cs_id=1041902 &p_id=2029&seq=1&format=2
Be aware that this will only transfer video. You Macbook Pro cannot combine audio through DVI to HDMI. You will need to listen to the audio through the Mac speakers, or attach speakers or a sound system to the Mac earphone jack, or determine if your TV has the ability to accept external sound from the Mac while showing video through HDMI (few can). -

Aside from Wake on LAN, how can I turn on my S10 without pressing the Power Button?
Hi,
FIrst of all I have not tried Wake on LAN on this S10 of mine, yet. I don't even know if it will work or not.
Anyway, this is my main concern. I'm planning to mount my S10 on the back of my monitor, I'll be putting a wire mesh kinda box that will hold it. I will then hook the VGA monitor/audio cables to my S10. I'll also be hooking my wireless Keyboard so it will look clean as possible. With this setup, of course, the LCD lid will be closed and I'm thinking of ways on how to turn it on with the Lid closed. I'm currently finding ways on how to do this? I was hoping NOT to go to the rear of my monitor >> lift the S10 from the mesh box >> press the power button >> close the lid >> place it back to the mesh box mount.
The wireless keyboard has a power on option (I have Logitech MK300) but does NOT work. Would a Wired USB keyboard work?
Fortunately, I have a deskop computer (which has its own monitor) that will sit beside my S10/Monitor. The two computers (Desktop and S10) will run independently.
What do you think guys? What options can I go with? Is my only hope Wake On LAN? Oh yeah, it is even possible with the S10?
Maybe there is a USB device or a hack that can be done (not voiding the warranty)?
Thanks!Yeah, I just noticed it So does this mean I can't wake my S10 thru LAN right? Anyway, do you have any suggestions? I'm looking for a Docking Station, but I can't find any. Can a USB replicator turn this on? Any ideas would be greatly appreciated
Maybe you are looking for
