Why the CPU Frequency will just stated at 1189MHz when the X230 had AC Power ONLY (Battery Removed)?

Dear All,
I bought a X230 (i7) notebook.  I found that if removed the battery from the notebook and only use AC power with the X230 Notenook.  The CPU frequency will stated at 1189MHz.  It will not change no matter how many program the notebook is running.  The CPU frequency will rise to 2.9GHz or upto Turbo when the Notebook with battery or battery and AC power.  Why the CPU Frequency will just stated at 1189MHz when the X230 had AC Power ONLY (Battery Removed)?  This is not right.  Any setting in the X230 Notebook need to change?  Please help.
Solved!

The situation is probably the same as it was for the X220. A 65W power adapter by itself doesn't provide enough power to run the computer at full speed, but it can when combined with a battery. However the 90W adapter may be able to run the computer at full speed without a battery.
As it was with earler X-series. This is by design. It allows people to travel with the smaller, lighter 65W adapter. However for maximum speed and flexibility it's best to always use the 90W adapter.
