15" MacBook Pro "Santa Rosa" Hard Drive Cable

Machine Type: MacBook Pro (sliver keyboard)

Symptom: When the laptop is moved, the system powers off, even while running off AC power.

Likely Cause: Bad Hard Drive cable.

The hard drive cable on the MBP consists of the SATA hard drive interface(1), the connector for the sleep light(2), the IR connector(3) and the logic board interface(4)

If specific care is not taken when changing out the hard drive, the cable can become damaged. This damage may not be noticeable to the naked eye.

When the hard drive cable gets damaged, the signal can get broken when the cable is flexed (the Mac is moved.) When this occurs, the system sees it as a possible short and immediately powers off.

So far, we’ve only seen this issue on books where the hard drive was installed by a 3rd party or DIY.

Although the issue at first appears to be power or logic board related, a new hard drive cable is all it takes to bring the MacBook Pro back to normal.

This is a good example of how delicate these cables are and why proper cable handling is important.

Keeping your email inbox organized can sometimes be a real chore. If you get a lot of email, you’ve probably already created folders to keep your emails organized (business, personal, finances, etc.)

In Mac OS X Mail, you can save a lot of time by using “rules.” Rules allow you to automatically move and organize incoming emails, set auto responders (out of the office messages,) play alert sounds and even run Apple Scripts.

Setting rules in Mail is really easy:

1. Start by selecting an email that you would like to create a rule for (select a bank statement email for example.)
2. From the menu bar, open the Rules section in Mail. Mail > Preferences > Rules
3. Create a new rule. You can call this one Finances and set the rule that when ever you receive an email from this bank, the message is then moved to your Finance folder. You can add multiple addresses so other financial emails will also follow this rule.

Setting up rules in Mail takes only a minute to setup but can save a lot of time in the long run. Entourage also has this functionality, but the Mail setup is as easy as it gets.
