Macbook Pro Extremely hot with NO cpu usage

I have a Macbook pro 15" (Mid-2010). Recently my mac is running extremly hot specially when connected to the AC power.
I'm using iStat Pro to monitor sensors, and while charging sometimes CPU reaches 101 degrees celsius. When I detach the power cord, it stays at about 80-85 degrees. My cpu usage is normal, about 1-4%. All the bottom of my mac feels hot, specially under the CPU, but the middle parts too. Fans are also working with highest speed.
Is it a known hardware problem?
Another problem which I've had around the same time, I use "Hardware Growler" to check for usb connections. When I connect a USB flash disk, sometimes it shows a lot of connections and disconnections for Keyboard, Trackpad, IR Remote and stuff. Pushing the usb around doesn't show the same symptom, so it's not a broken board or connector or something.
Have you seen a similar problem? What can I do?

I've solved my problem by resetting PRAM and SMC. I'm writing my solution here so others can try it if they have the same problems.
To reset PRAM, follow instructions in this link: http://support.apple.com/kb/ht1379
and to reset SMC, follow this link: http://support.apple.com/kb/ht3964
I think my problem started when I upgraded Parallels Desktop to version 7 (from version 6). I'm not sure if it was the cause, but some kernel extension in parallels could've corrupted SMC and/or PRAM.

If you choose to use garbage such as "Intego VirusBarrier" you are going to need more memory, a lot more. I suggest you uninstall it according to its instructions, and evaluate your Mac's performance without burdening it with completely useless junk. As long as Intego remains active, your Mac will have few resources remaining to do anything else.
Using Intego's "Virus Barrier" and "Net Barrier" products on a brand new Mac containing nothing but one minimally configured user account resulted in performance degradation so severe that it became nearly unusable. No knowledgeable Mac user would consider using it even remotely tolerable.
Intego should only be uninstalled using the uninstaller included with it. Don't use anything else. A successful uninstallation will result in the following:
After that, restart your Mac. Other Intego components will remain but they will be inert and will not affect your Mac's operation.

MACBook Pro - Extremely Slow with Freezes

Hi,
I have this macbook pro model
Model Name:          MacBook Pro
Model Identifier:          MacBookPro9,2
Processor Name:          Intel Core i5
Processor Speed:          2.5 GHz
Number of Processors:          1
Total Number of Cores:          2
L2 Cache (per Core):          256 KB
L3 Cache:          3 MB
Memory:          4 GB
And with 385 GB out of 499 GB of free memory.
I have practically nothing on it, no huge files & not more than the basic apps., nothing !
However, I have a very slow response. Word sometimes takes a minute to open when I only have just Chrome running in the background.
It gets worse when many apps are running together, but even then its only basic apps nothing major. Safari would normaly take not less than 20 seconds to open. I have just dropbox thaat run automatically after start up but nothign else. Still most of the time I am faced with the slow response. The spinning beack ball is always on to, which makes me force quit alot of time.
My battery is working quite well
Thanks for the feedback !

Late 2011 Macbook Pro loud fan at 30% cpu usage...

Im new to to MBP (about 2 a month and half now...) and its whisper quiet when idle or in the first hour ive started using it... but after writing papers or surfing for a few hours the fan kicks on and its surprisingly loud! My CPU isnt above 30%, and the case even gets pretty hot. Yesterday I swear it almost burned my lap within an hour of use it was so hot on the bottom!
Ive just never heard of the fan getting this loud or complaints about a hot case from fellow users. So im wondering if this is normal...
Ps. the fan doesnt sound like its rubbing or performing poorly, just at a very high speed. My old custom desktop pc had 8 x 80mm case fans and at time this is almost about the same volume!

Mac Notebooks are not meant to be used on your lap. They need to be placed on a flat surface such as a desk to allow for proper ventilation. Also, define "hot" add the iStat widget to your dashboard and report back with what the temps are. Also, MBP's are known to run hot..

Why is my macbook pro extremely hot after Lion install

After successfully intalling Lion, my mac book pro is getting very hot.

… indexing of spotlight is already done … As soon as i start using Safari to browse through some pages the fans start to rev up, even if there's no flash animations …
Issues may be not limited to animations.
Try uninstalling Flash then whenever playback of Flash content is critical:
drag the icon of the page (to the left of its address)
from the toolbar of Safari
to the Dock icon for Google Chrome, where the player is integral (and bugged in the ways outlined above) .
Some technical detail of what's new in Lion is alrady published:
What's New In Mac OS X: Mac OS X v10.7 Lion
For more in-depth knowledge, without paying to join a programme you can view at least some of the following:
WWDC 2011 Session Videos - Apple Developer
My uneducated guess is that some of the cooling and/or load — maybe not demonstrable by Activity Monitor — is GPU-related, something to do with tightened integration between OpenCL and Grand Central Dispatch.
Incidentally I'm currently not convinced that iStat Menus 3.18 (3.18) offers a suitably comprehensive guide to the gamut of things that Apple does with 10.7 (Build 11A511).

Macbook Pro "Battery not available" + kernel_task cpu usage

Hi everyone,
I have done some searching around and I see that both of these problems are reasonably common, but I don't see much discussion of them happening together.
First up, a description: My early 2011 15" mbp (240gb vertex 3 ssd and 750gb hdd in optibay, running OSX 10.7.3) became sluggish a week or so ago. I noticed unusually high cpu use by several tasks in activity monitor (usually kernel_task but also finder, itunes and others). Usually when I am epeiencing this problem I also notice that the battery icon has changed to a cross and reports "no batteries available". If I unplug the power, the machine instantly powers off and will not power back on without the power supply connected, at which point the white lights on the front of the machine flash for a few seconds before the machine boots as normal. Pressing the battery meter on the side causes all LEDs to flash. Interestingly, if I power on with the power supply connected, but then unplug it as the machine boots, the machine continues to run (although the system still fails to detect a battery). This leads me to believe that the battery itself is sound. Sometimes these problems happen independantly of each other. For example, I have noticed the resource use is high even in the brief periods where the battery is detected.
Now the twist: if I boot into Windows 7 the battery is detected as normal. If I then reboot into OSX everything works normally for a random amount of time before the problem reoccurs.
Things I have tried:
Clearing various cache's
Resetting the SMC (power button hold method is what I tried, though I got no feedback from the machine itself that anything had happened and I am unsure if this is the correct method for my model).
removing all login items for my user account
deleting finder preferences
removing all non-apple startup kexts
So what do people think? Broken SMC? If it did turn out to be this issue, is this a relatively easy fix? Will they replace the whole machine? I have 3 years of apple care, but this is my main work machine and I can't do without it for more than a couple of days. Also my nearest apple store is a train ride away.
Thank you for any help you can offer.

Since you have tried the SMC reset, I suggest that you make an appointment at an Apple store genius bar. The evaluation will be free regardless of warranty status.
Ciao.

For Skype Video, which uses CPU and GPU to encode and decode the video, these sound about right.
Best to place your MacBook Pro on a solid (non-cloth, fabric) surface to help heat dispurtion.

Can't connect macbook pro to internet with airport extreme

Can't connect macbook pro to internet with airport extreme

If you have ethernet still on your MBP plug it in by ethernet and tell me if that works.
Tell me how the Airport is setup.. what broadband modem and router you have.
What OS on the laptop? Yosemite I guess.. since it is the most troublesome.
Did it work before whatever change was made? Has it worked in the past? When did it stop and what did you do that coincided with it stopping?
Upgrade to Yosemite??

HP Pavilion external monitor has stopped working with my Macbook Pro (Mid 2012) with OSX 10.8.3

HP Pavilion external monitor has stopped working with my Macbook Pro (Mid 2012) with OSX 10.8.3. When I purchased the monitor a few weeks ago it worked perfectly when computer was in clamshell mode or with lid open. Now external display has stopped working. When I turn on display it scans for signal but does not find it and then immediately goes into sleep mode. I am using a DVI connection with the adapter for the mini display plug. REALLY FRUSTRATING. Any help would be extremely appreciated.

Hi lancekatigbak,
If you're having issues with the display out on your MacBook Pro, you may want to take a look at the troubleshooting steps in the following article:

Why does my macbook pro get hot

Why does my Macbook pro get hot while I am only on my email account? This is a recent change. It gets too hot too put in my lap. Is it a battery issue.

Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

If you are on Yosemite, and have a CoreStorage volume (the default), it is not visible on the Windows side. The Apple HFS driver cannot read CS volumes.
You can verify this by running the following command in OSX Terminal.
diskutil cs list
If you get any output, such volumes will not be visible.
As a work around, if you really need it, check the 'Revertible' value. If it is yes, you can revert it to HFS+ by using the following command
diskutil cs revert
Here is the syntax for the command. The LVUUID parameter can be seen as a long string for your Logical Volume. Do not use the Logical Volume Group or any disk UUIDs. If you need the exact command, please post the output from the diskutil cs list command?
diskutil cs revert
Usage: diskutil coreStorage revert
MountPoint|DiskIdentifier|DeviceNode|lvUUID
[-stdinpassphrase | -passphrase [passphrase] | -recoverykeychain file]
Convert a CoreStorage logical volume back to its native type.
The file system must be mounted and resizable (i.e. Journaled HFS+).
Ownership of the affected disk and a passphrase (if encrypted) is required.

Brand new Macbook Pro (early 2015) with upgraded ram lagging in the simplest tasks

I received a brand new 13 inch macbook pro (early 2015) with upgraded ram (16 gb) about two weeks ago. I was expecting it to do tasks faster than its predecessors (the macbook pro which came directly before it, which my father owns, and the early 2009 which is now a family computer), but became dissapointed when it began crashing basically as soon as i started using final cut pro, and ever since it has been lagging everywhere else! I have check my activity monitor regulary due to this issue and have noticed "kernel_task" taking a large percentage of CPU (when im not using the computer all that much around 10%) and it uses 1.5gb of ram upwards constantly without fail! I am aware that this is the operating system so i dont really want to fiddle around with it but it does sound a little bit high to me. Originally it was slightly tougher work on final cut that would crash it, hence why i haven't seriously questioned it until now, but currently i cannot even move my curser around without getting the spinning beach ball of death! Please help me!

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

I tried last week. The best I could get was a discount on the repair, but the damage to my logic board by the GPU caused it to no longer boot. The program ended in December last year, but it has been extended in the past.
If you have no other damage you might be able to get a flat rate tier 1 repair if you are in the USA.
