E7440 laptop cannot upgrade BIOS from A14 to A15 using a pen-drive

I'm trying to upgrade bios of my e7440 from A14 to A15 using a bootable usb stick, in order to fix the keyboard 'double-typing' problem under linux OS.  

But when executing 'E7440A15.exe' in freedos system prompt it complains "Unable to locate the BIOS update payload".  

Could someone tell me why would this happen and how can I proceed?
