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.

TS1713 my power adapter gets very hot on my mac book pro is this normal

my power adapter gets very hot to toutch on my mac book pro is this normal

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.

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.

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.

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?

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

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...

HT4060 When I charge my ipad on some occasions the plug gets very HOT. the ipad still charges but slower.????

When I charge my ipad using the small UPSpower adapter, the adapter gets very HOT on about every third use. It still charges but more slowly. Is any one having a similiar problem?? An sugstions as to how to correct it???

Not staff or owner by a long shot.
I just know that anecdotally I have seen people reporting issues with their mini's charging. Is there a real issue or not? I don't know. Not a day goes by that a person doesn't post here complaining that their iPad won't charge and it turns out that they're trying to do it via USB or with the iPhone block.
But while there are a lot of user fixes sometimes it's good to have the pros take a look at things,and at the very least document that there has been an issue.
the four main reasons an iPad won't charge (beyond being plugged into a USB port)
Bad cable
bad outlet
bad brick
rule those out and it leaves issue with the iPad.

I am using a white 13inch 2009/10 macbook, purchased in the US. Am currently using it in the Philippines, where it is 220v. I know my adapter says it works from 100-240v, but is it okay to use longterm? I think my mac gets very hot now? thanks

All Apple power supplies work world-wide with the proper plug adapter.
I have my MacBook plugged into the grid all the time, 24 hours a day w/o any problems.

In my macbook pro 15 inch mid 2012 model, my cpu and gpu will get very hot, when gaming or rendering sometimes over 200F. The fans only spin at max about 2900 rpm, when their max is 6400. I downloaded a fan control app, but how can i fix it?

Hi rhaughan,
I see that you have concerns about your operating temperature of your computer while using resource-heavy applications such as gaming applications. I have an article that will address some of the concerns you have mentioned:
Mac notebooks: Operating temperature - Apple Support
http://support.apple.com/en-is/HT201640
While there are third-party utilities that measure the temperature of a notebook computer, it is important to understand that these utilities are not measuring the external case temperature. The actual case temperature is much lower. Never use third-party applications to diagnose possible hardware issues—instead, contact Apple or go to an Apple Retail Store or Apple Authorized Service Provider.
You should also see this article for even further information about your fans:

MacBook not going to sleep and getting very hot

I just purchased a MacBook and have been using it for a few days. I have noticed that it does not appear to go to sleep correctly and gets very hot in the process. I finished working on my MB about 45 minutes ago. At the time it was connected to the mains and I disconnected to catch my next train. I shut the lid and after a few minutes the sleep indicator light at the front dimmed once then stayed on permanently. I could not hear the drive spinning (though the drive is quiet on this machine and there was a lot of background noise) and assumed all was OK. Anyhow, I have just taken the MB out of its case some 45 minutes later and it felt extremely hot (almost too hot to touch, I would guess around 50ºC). The sleep indicator light on the front was solid white. I opened the lid and the machine woke up. Something not right here....Also power remaining was down to 72% so something has been using up a lot of energy and heating up the aluminium!
Tony
ps. Whilst writing this email the MB has cooled down considerably but still warm.
ps2. Probably not related, but I have firmware password protection enabled
null

I did see some of the other posts, but nothing about the MB getting so hot.
I tried sleep from the menu and this seems to work (though I have rebooted the machine since the above report).
What worries me is the potential fire risk/damage to the MB, the case was extremely hot.

My iPhone 3GS will hold a full charge for only a short time, and gets very hot when not in use in my shirt pocket. Any ideas?

My 3GS iPhone will not hold full charge for very long. It gets very hot in my shirt pocket even when hot in use. Any ideas?

Double-tapping the home button does not show apps that are running. This is not a task manager, it is merely a list of recently used/accessed apps.
Basic troubleshooting of the device is reset, restart, restore. Has a reset or restore been tried?
Check to see if updates exists for the apps, this could be a simple issue of a badly coded or buggy app that needs to be updated.

Battery gets very hot during use and doesn't last long, fan runs at high speed, computer won't shut down

Macbook Air isn't a year old and I don't leave it plugged in ever. The battery might last 2 hours and gets very hot. In addition the fan runs at a very high speed. The computer won't shut down in a normal way. I have to hold the power button down to shut it off. Can someone suggest something please.
Thanks.

I got my 2nd iphone 5s brand you, it s getting very hot after 10 min of usage

I got my 2nd iphone 5s brand you, it s getting very hot after 10 min of usage

It means take it back to where you bought it from. If you don't want to do that you'll have to be more specific like how long you've had the phone and how you are using the phone when it gets hot. That kind of information. The more we know about the phone the easier it is to diagnose and offer suggestions.
