My Macbook Pro hits 70°C when browsing
my macbook pro (early 2010 15" intel i5 processor) regulary gets up to 70°-75° according to iStat when I'm just browsing the internet on chrome. I can't figure out why it gets so hot. I have the brightness on low, nothing running in the background and it still gets wayyy to hot. I've done the hardware test, nothing wrong. Why does it get so hot?
Chrome automatically invokes your MBP's higher-powered, hotter-running discrete GPU. To gain manual control over switching, download and install gfxcardstatus:

If any of the sites you visit contain streaming video, particularly Flash video, that's good for at least 20°C over and above normal operating temperature. Many sites contain Flash junk, and even if it's just advertising, it will cause your machine to heat up.
All that said, 70-75°C is nowhere near the danger threshold for your MBP's processor temperatures.

When I start my lap top, it shows the apple and the line uploading but it only goes like to 1/3 and then it goes blank for some seconds, then it turns off by itself and turn on again and happen the same, apple logo, line .. the noise like-fan going on, then turn off and turn on again. Tried starting holding option command P and R key and didnt work either. Starting to think I have lost all my data inside
Try a SMC reset.

It might be helpful if you indicated the exact model/year of your MBP. Are you running Lion OSX?

So in the last few days I’ve noticed that pressing my volume change keys actually isn’t changing the volume on my macbook pro at all. When I press the volume up or down keys, it makes the recognisable pop sound but stays at the same volume while the squares go up or down. I mute it but my computer still makes sound. It’s the same with the volume control up the top of the screen, too. I slide it up and down and it doesn’t change the volume at all. The only way I can change the volume is with my speakers or the program I’m in (iTunes, VLC etc). I restarted and it seems to be okay then I go to change it a couple minutes later and it’s back to not working again.
I’ve checked my settings- the “use all F1, F2, etc. keys as standard fuction keys” is not switched on, and I have tried a suggestion of moving the com.apple.systempreferences.plist file out of the library and onto the desktop and restarting and neither of those seem to make any difference whatsoever. I’ve tried to find online forums but the only suggestions I found were those two and they didn’t work.
I’m just annoyed because I usually have the worst luck with technology but my macbook had been going strong and I got it because of the apparent lack of things that could go wrong, but of course even if there is one thing that could go wrong it will happen to me.
Please help!You migh give resetting your NVRAM a try:

WHAT DOES IT ALL MEAN??That many cycles is amazing service. A battery that consistently shuts down at about the same charge level percentage every time probably has a bad cell (that info came form an Apple technician) and needs to be replaced.
It's given you far longer service than many of us get, and may be a new record around here for cycle count! -
What's wrong with my macbook pro (15" early 2011) when i connect it with TV via hdmi
What's wrong with my macbook pro (15" early 2011) when i connect it with TV via hdmi
Hello Alex,
It sounds like you are getting excessive CPU usage when connecting an external display via HDMI to your computer. I would try the troubleshooting steps outlined in the article named:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the systemYou can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.
Cheers,

How do I FTP files from a security camera to iCloud so they can be retrieved back to my MacBook Pro whenever I connect when travelling?
RussDo you want to watch the live feed of your secutiry cameras or recorded footage?
In either case, I don't think iCloud is your solution.
For the first one, check with your security camera software, they usually have this option of broadcasting, so you'll know how to access it.
For the later, you should use something like Dropbox (www.dropbox.com), since iCloud file sharing is, up to this date, app restricted.
Hope it helps.

Why does my macbook pro "goes to sleep" when charging?
Why does my macbook pro "goes to sleep" when charging? It is working fine without charging but once I attach the charger to my laptop, it just blacks out or goes to sleep mode and I can't wake it up unless I unpluck the charger.
I read from threads that it is a logic board problem....How do I solve this problem?Try an SMC reset. Follow the method for "a battery you should not remove yourself."

I have a license for CS6 on my MacBook Pro. I want to purchase an iMAC and be able to do my heavy duty Photoshop processing on this new iMAC when I am at home I need to keep CS6 on my MacBook Pro and use it when I travel. How can I have copies of CS6 on both machines. I am the only user of this software.
You can install and activate CS6 on both machines perfectly legally.

MacBook Pro goes to sleep when copying files from attached drives
I have noticed that since installing Yosemite my MacBook Pro goes to sleep when it is in the middle of copying a large number of files. When I wake it up the copying continues.
I have also noticed that when I am watching videos from my shared iTunes library on an Apple TV the video will stop after about 15 minutes and the connection to the library is lost because the MacBook Pro has gone to sleep. When woken up then access to the library is restored but I need to reselect the movie and then resume.
I have changed the power saving options to do not let drives sleep when idle and do not sleep laptop.
Anyone else have any experience of this or better still a fix.
Thanks in advance.I have just found that if I turn off the display sleep in the power settings then the problem is resolved. It means though that the screen on my MacBook Pro is on all the time albeit with a screen saver.

Put my macbook pro to sleep. When I opened it, the desktop window is small and I can't resize it. All applications now run in the smaller size window. Can't make it fill the screen. Just switched from windows. Thank you.
Check to see if the resolution has been changed in System Preferences.

My macbook pro shows blank screen when I started..help me..
My macbook pro shows blank screen when I started . (It's like in same state when power off. ) fan sound and hard disk is running. So i connected it Through external monitor via mini display to VGA cable. I can see everything on external monitor. My display of Mac needs to change? How much it cost ?? I found so many forum discussion said that if nvedia card is faulty then its happen...let me know suggestions...I given it to apple care service station n they r telling yr display needs to change its cost me a lot.. I can't afford. And can't spend that much for 3 yr old version as new versions of macbook pro is cost vice reasonable.. can I have any suggestion?
If running 10.7 or later hold down Command-R at Startup.
This should invoke recovery Mode.
Choose Disk Utility.
Select your Hard drive. Inspect the SMART Status in the lower right of the window for "Verified".
Select the Mac OS X Volume (originally Macintosh HD) click (Repair Disk)
If errors, run again until it comes clean or gets stuck.
Report any error messages. -
Does keeping a macbook pro plugged in even when fully charged damage the battery in any way?
Does keeping a macbook pro plugged in even when fully charged damage the battery?
no it will not, your battery stops charging when it reaches 100%. you can verify this if you'd like to through system report - power.
once in a while however, it's best to use it under it's own power and charge it back up once it's down to 75% to keep the battery in optimal condition.
