hi
my laptop when i press a poweron button it gives me this message
'MANUFACTURING MODE LEVEL (67)
PRESS fn-x to go to nomal running mode"
when i press that fn-x it says
"COMPUTER IS DOCKED AND ONLY BATTERY POWER IS DETECTED THIS CAN HAPPEN IF THE BATTERY IS NOT PROPERLY CONNECTED TO DOCKING STATION OR POWER CARD IS MISSING SO YOU SHOULD UNDOCK,REDOCK" but i have checked the battery and adapter everything seems to work perfectly fine help me pls..

Is the laptop connected to a docking station?
If so, does it do better if you undock it?
