Hi, I am having a Toshiba tecra m9 laptop, with windows 7 operating system installed in it. The laptop is having a boot problem since I installed a new battery replacing the old one. The previous battery which I used was the original one and the new battery which I am using now is of high capacity with 12 cell, 11.1v. Since I had tried to boot the laptop without battery it was ok. Again when I replaced back the battery the system is unable to boot. Can anybody please tell me what the problem is.
