Problems with 2010 13" MBP

[csjo00]

Over the past two months or so, my MBP has significantly slowed down in speed and normal operating temperature has risen around 15 degrees C. I'm not doing anything differently application wise. iTunes, Twitter, Mail, Safari, occasionally Word or something.

WindowsServer and kernel_task seem to be the highest resource hungry services running in Activity Monitor.

I've taken the back case off and blown out what little dust there was. I haven't replaced any hardware. I have a warranty through Bestbuy's Geek Squad, but I'm seeing if there's any "natural remedies" before I do that.

The only thing I can guess is that my battery is causing damage since it's "Replace Soon" condition.

Any ideas?

1. Launch Activity Monitor
2. Change "My Processes" at the top to "All Processes"
3. Click on the CPU column heading once or twice, so the arrow points downward (highest values on top).
4. Click on the System Memory tab at the bottom.
5. Take a screen shot of the whole Activity Monitor window, then scroll down to see the rest of the list, take another screen shot
6. Post your screenshots.

Those are parts of Mac OS X.

That won't cause damage, unless the battery swells. This should answer most, if not all, of your battery questions:

While OnyX is a good app for specific purposes, you don't need "cleaner" or "maintenance" apps to keep your Mac running well, and some of these apps can do more harm than good. Some remove files/folders or unused languages or architectures, which does nothing more than free up some drive space, with the risk of deleting something important in the process.

These apps will not make your Mac run faster or more efficiently, since having stuff stored on a drive does not impact performance, unless you're running out of drive space. Some of these apps delete caches, which can hurt performance, rather than help it, since more system resources are used and performance suffers while each cache is being rebuilt.

Many of these tasks should only be done selectively to troubleshoot specific problems, not en masse as routine maintenance.

Mac OS X does a good job of taking care of itself, without the need for 3rd party software. Among other things, it has its own maintenance scripts that run silently in the background on a daily, weekly and monthly basis, without user intervention.
