100% CPU utilization on AC adapter

When the battery level is below 90% and I plug AC adapter, CPU utilization level goes to 100% until battery level is 90%. 

It is not with Operation Systems, because the problem is on Linux and Windows. It's not a battery or AC adapter problem, because I've tested with other batteries and AC adapters.

 

What advice can you give to me?  

PS. My Laptop is HP Compaq 6720s

Mrixs,

 

Have you installed the latest BIOS (F.0D N)?

Try a different AC adaptor, I had the same type of issue and it was the AC adaptor..
