Thread: MacBook

  1. #1

    MacBook

    Recently, the bottom has become hot. It is a new thing and I'm being careful as

    I got a blister from my HP when using it literally as a laptop.

    Any suggestions as to why it's running hot? (Not a year old yet)

    Everything being cramped up in a tiny box and summer im guessing.
    Could have been a cpu heatsink failure.

    If you could find something like Real Temp software http://www.techpowerup.com/realtemp/
    but for Mac and tell your temps. Im pretty sure people can give you better explanations why its so hot.

    Do you normally run it on battery and this time you had it plugged in? Laptops run slower and cooler when on battery to conserve power, and run their fastest and hottest when plugged in. Or, even something like watching a video will also make it run hotter, videos make the processor and other chips do much more work thus running hotter.

    Did you hear the internal cooling fan kick on?

    My Macbook pro 15 " will cook ya on elec power, and still is pretty warm/hot even on batt, I always keep something between it and my legs.

    I do use it plugged in. I believe the culprit maybe my nephew who watches videos and leaves it on the couch.......

    Will it ever return to not being hot?

    Is it possible that there is dust or pet hair inside? My MacBook pro was getting hot and when I opened up the case to install more memory and a ssd hard drive I took the opportunity to blow it out and it's been better since.

    Liz - Could be what some have said, or you may have one or more imported apps running in the background without your knowing it. Check what's going on in the background via Activity Monitor, where weird stuff will stand out from routine activity.

    First of all tho, have you tried just repairing disk permissions?

    >>Top bar: finder>go>utilities>disk utility>"macintosh HD" in sidebar>then "repair disk permissions" in lower screen.

    Throws out any garbage left behind from errant websites - games are a big culprit. Works on my 2009 macbook.

    What you DO need is the following source:

    Go right down to hardware/macbook, where you can succesfully search any and all questions macbook !!!!

    Enjoy the hunt.

    Ahoy-Hoy, Liz!

    You may want to take a look at the The Official "My MacBook/Air/Pro is overheating, what do I do?" Guide. I thought I was having a heat issue with my Intel iMac because it would suddenly shut down without any warning. I downloaded the free version of iStat Menus 2.0 which turned out to be a useful app.
