The power adapter gets very hot.  Any suggestions?

The power adapter part that plugs into the computer gets very hot.  I have replaced the battery and replaced the power adapter.  It also has a hard time connecting and recharging the battery.  Is it possible to change out the plug in part in the computer and is it expensive?  Does it sound like this is what is needed to fix it?  Its about 3 years old.  Any suggestions would be appreciated.  Thanks.

Hot is normal for the charger but very hot is not. If it were mine It could be that your MBP is drawing too much current. I would take it to the Apple Store and have it checked out.

  • 15" MacBook Pro Power Adapter gets very hot.

    I have a 15" MacBook Pro that I am using the older charger with the adapter from Apple.  The adapter is getting to a measured 137.9 degrees, a.k.a. HOT.  Anybody have any thoughts on this?

    A lot of people report this. Try turning the connector 180 degrees and cleaning the terminals. Apparently that helps in most cases

    If the Mac is too hot to touch, take it in for service.

  • AC adapter gets very hot

    I have a new Thinkpad Edge e530.
    The adapter gets very hot when the battery is charging.  Not so hot that I can't hold it, but still, very hot.
    Relevant specs:
    * Adapter:  65 W
    * Battery:  "the bigger one" (6 cell LI Bat-75+,62WH)
    * Graphics:  integrated, not discrete
    With the bigger battery, am I supposed to have the bigger (90 W) adapter?
    Is the amount of heating I'm experiencing (very hot, but not too hot to touch) enough to be of concern?

    Hello dbuser!
    Welcome to the Forums Community! How long have you experienced the A/C Adapter getting hot? Were you using a different battery before the 6 cell?
    According the the e530 Personal Systems Reference the 65W Adapter is the correct adapter for the 6 cell battery. It is possible that you have a defective adapter. Does the adapter make any noise, buzzing or cracking sound? If it is making any noise there is a definete issue with the adapter you are using.

  • Recently bought pro retina 15" with a super drive. But when I played a dvd the quality wasn't very good, any suggestions?

    Recently bought pro retina 15" with a super drive. But when I played a dvd the quality wasn't very good, any suggestions?

    There is a good chance that the DVD is OK and the machine is OK since a DVD's resolution is set for a television and not for a computer with a resolution 4 times that of the tele (at least).
    What are you using to play DVD?
    What is the DVD and what does it say on the cover about resolution or aspect ratio?
    Just because you have a retina Mac doesn't mean you will get an excellent picture from low resolution media, if you are using DVD player use the menu option for 'Actual Size' this will play it at the resolution for the DVD, any larger then it will start to pixelate.

  • MacBook Air power adapter, getting extremely hot to the touch, is this normal?

    Just purchased my MacBook Air 13", I'm very impressed with it but, I have one question. Is this power adapter supposed to be like this hot, I could fry an egg on it..
    Just curious, maybe I need to return the supply for a new one? Is this condition normal?

    Hi TOWjr,
    The power adapter will definitely get very warm if you're charging the battery at the same time that the machine is under high CPU/GPU load. So yes, it can be quite normal.
    Try this... let the battery run low (sub 25%). Turn off the machine, connect it to AC power and let it fully recharge. During the recharge process (Amber LED) is it as warm, cooler or hotter than what you're experiencing now? After the recharge is done let it sit for about 30-45 minutes. Is it as warm, cooler or hotter?

  • My adapter getting very hot

    hi everyone please help me...i have a one problem.During recharging my 60watt adapter is getting very hot. about 60celsuis.Is it normal? 

    If it is too hot to rest your hand on without injury, it's too hot. At about 60° C, that is certainly possible.
    Try another power receptacle since poor utility power quality may affect the adapter's temperature rise. If it is still 60° C after trying a number of different power sources, have both your power adapter and the MacBook Pro evaluated by Apple.

  • Power supply get very hot!

    I just bought a Pavilion dv6-6c35dx laptop and have noticed that the power supply gets really really hot, to the point that it scares me and I disconnect the laptop. Does anyone has the same problem?

    Same problem here on my dv6-6c35dx.
    I didn't know about the power cord recall, and I bought a new ac adapter, power cord and replaced the battery. No change, the adapter gets really hot, too hot using the 2 second rule! Experienced chefs use it to determine if a grill is hot enough by touching it for no more than 2 seconds.
    I'm now putting it on a ceramic plate to make sure it doesn't smoke something when its charging. I hope HP knows this is a problem. Maybe the battery charging rate can be slowed and this may help.

  • The Power Adapter is Scalding Hot

    I'm using my MacBook right now for a ton of stuff and the fans have been going nonstop. This is nothing unusual, but my power adapter (I don't know if that's the correct name for it; I mean that white box) is unbelievably hot to the touch. I think I burned my foot on the thing. Does anyone know of a way to keep this from happening? Is it defective or do all power adapters get this hot when working hard? Thanks

    The power adapter can get quite hot.
    Regarding your fans, of course the macbooks can run quite hot, but you may want to check your activity monitor to see if you have a stuck process taxing the CPU.
    Yesterday I found a widget that went unresponsive and through the cpu to 150%, I had to close the widget and force quit the process.
    People have found some printer help utilities in the monitor will do this too!
    Good luck.

  • Question about X-series with the bundled 65W adapter, gets very hot

    Hi all,
         My company purchased many X230 notebook in last year.
         some are standard configuration (i3 CPU) and some are (i5 CPU).
         The i3 seems to have no problem.
         However, the i5 model had some issue that it can't full run all the 4-core in high load when connecting the bundled 65W AC adapter, and the adapter got hot. After investigation, we change to 90W AC adapter and the problem is gone. All the 4-core runs correctly and the 90W AC adapter is cool.
         The reseller said that the 65W should be factory package and they will not provide any warranty if we use it incorrectly with the 90W adapter (but the lenovo homepage says the adapter supports....).
         Now, we are considering the X230i model with the same upgrade to i5 CPU.
         Can someone provide feedback if using the X230 / X230i + i5 CPU normally with 65W AC adapter?
    Regards,
         Donald

    Could this be the same or related issue?
    I have a T430s with integrated graphics and dual core i5 CPU. According to Lenovo sales literature this system will work with a 65W AC adapter. Also when I ordered the system online from Lenovo's site I was also given the option to select either a 65W or 90W adapter.
    At the office I use a 90W adapter. The system idles at under 40°C with the fan usually not spinning or spinning at slowest setting (according to TPFanControl) even when the system is under load. It may get as hot as 50°C when the system is under heavy load. But I've never seen it overheat or had the fan spin continuously at maximum speed, etc.
    When travelling I use a 65W adapter in order to minimize size and weight. In that situation the fan is always running and temperatures are usually in the 50°C to 60°C range. On more than one occasion system temperature has "run away" getting increasingly hotter, going to 80°C or 90°C.
    In one case the system shut itself down. I let it cool down overnight. When I rebooted I got a fan error. After that incident I sent the T430s to Lenovo for repair. The technicians found nothing wrong. From their report it's not clear if they replaced the fan or not. Nevertheless this "run away" temperature situation has recurred since then.
    From reading posts on this thread and based on my experiences with the T430s it seems to me that the 65W adapter doesn't have enough power for even a basic T430s despite what Lenovo's marketing literature may say.
    I wonder if the same conclusion doesn't also apply to your systems? Do your temperature issues go away when your system runs on a 90W adapter?

  • Battery Life is short and when i do charge the power supply gets to hot to touch?

    Hi! I'm not sure whats Wrong with my MacBook Pro 15" - Mid 2010, i7, 4gb RAM, 512mb Graphics.
    When i charge my MB it has a really short life (50 - 60 min) without using high demanding programs. I've had a look in system information and i found this;  Full Charge Capacity (mAh): 4858
    im not sure what it should be but does it sound like a healthy battery?
    My second question, the power supply is hot to touch is this a contributing factor? I took it in to apple and they suggested to buy a new charger, so £65 later and i still have the overheating of the power supply and the short battery life problems, HELP!

    That is not a good sign.  Check the connection on the MBP to see if there is any foreign matter or discoloration evident.
    Open System Information>Power and post this from your MBP:
    (make certain that the charger is attached)
    Also run an Apple Hardware Test.  You may use the appropriate original install disk for this which has the AHT instructions printed on it.
    Note that an error free AHT is not definitive.

  • Thunderbolt to Firewire Adapter gets very hot in use (?)

    I've had the thunderbolt to firewire adapter cable for a month, connecting either a 500 GB or 1 TB "G-Drive" bus-powered HD. I note the small box at the firewire end of the adapter cable becomes quite warm in use.
    Is this to be expected?
    It is worrisome from, at least, the perspective of economy of power consumption, on a MacBook Air, used frequently away from a power outlet.

    You might want to post in the MacBook Air forum, then. This is the Apple Thunderbolt Dislpaly forum...
