Hopefully one of you guys can explain something for me. I have fitted a new battery to my Toshiba laptop and since fitting it the keyboard and mousepad refuse to work. If I plug in a USB mouse that works OK but still no keyboard. If I boot into safe mode everything runs OK. I took out the battery and ran just on mains and everything runs fine and cpu is back to normal, putting the old battery in also enables the laptop to run OK. Thinking the high cpu usage might be malware I ran Malwarebytes and Combofix but they found nothing. Has anyone any suggestions as to why the new battery is giving these issues, never had any problems with other batteries I have fitted to laptops.
