Sony VGN-SR45H Battery Restrictions

[strelock]

I have a Sony VGN-SR45H that I purchased an aftermarket battery for. The BIOS will not allow it to charge the battery. I was hoping somepne could help me unlock the BIOS. I have mmtool, amibcp, and RW on the laptop, and have saved the current rom file using amiflash. I also have what I think is an update file from sony, but the laptop is from China, so I had to google translate the Chinese pages to get it so I am not sure if it is right.

Current ROM:http://www.mediafire.com/download/t7zxzeucwfl2jg3/R3220y1_Current_installed.rom

Update ROM: http://www.mediafire.com/download/mvt5x2...update.ROM

I think they are the same, the version numbers are the same.

Could someone either unlock the battery charging capability so that I can use a non OEM battery, or direct me what to change using the mmtool or amibcp software I already have? Any other unlocks I have would be awesome as well, thanks!
