That is because the power consumption of I5 CPU+GT 555M graphic are much higher than the battery can provide, so the system would auto downgrade the frequency. We have improved the CPU frequency to increase the overall system performance under battery mode.
Please update your BIOS and EC firmware to E16G5IMS.10M and EC 16G5EMS1.416 or newer version.
Note: Please must also flash EC firmware 416 after you flash BIOS version 10M.
