Yoga 2 pro power adapter overheating

Yoga 2 pro power adapter overheats when charging (it gets so hot that I can't even touch it).. laptop also gets too hot mainly at the centre..even keyboard gets hot..

But when laptop runs on battery, overheating resolves automatically..

Re: Yoga 2 pro power adapter overheating

Hi Trisha -  

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

Heat in any electrical circuit is caused by excessive current passing through either wires or components in the circuit that were not designed to carry that amount. This could be caused by fault conditions such as a short circuit between circuit paths which causes more current to flow, a component whose nominal value reduces or insulation properties decrease again allowing for more current flow etc.

 

The adapter will get warm while charging a powered-off unit and warmer still running the laptop. If it's truly too hot to hold more than a few seconds, I would suggest that you call in for immediate attention for your adapter as this may pose non direct issue with the system board and ports in the long run.

Hi,

my yoga pro2 laptop/ powerpack (bought Jan 2015) overheated and burnt my sofa. Could have burnt 3 year old and left longer ....

Has anyone else had this problem or potentially?? I see comments re overheating.  

Why did this happen? Surely this is dangerous/ a fault?

Re: Yoga 2 pro power adapter overheating

Really this is really strange. A laptop's most critical (and warmest) components can easily reach 60 °C above the environment temperature. They're designed to withstand this torture, because notebooks don't usually leave a lot of room for efficient cooling, nor can they afford to be as power consuming as other systems. When the room temperature goes up, so do the temperatures of the processors.

 

Temperatures at about 75 C might warp the plastic that the computer case is made of, but it will not damage the internals.
