hi, i have a problem with a acer laptop. i bought it about 2 years ago for my brother. he lock his bios with password and now his windows crashed so i want format it but i cant boot it by external drives. i try to reset cmos battery. but it cant work. so i go to a third party repair center but they also cant fix it. they suggest me to go to acer service center. but i am not able to go there due to my busy schedule. If manage my time to go there also i dont know they can solve my porblem or not. so can you guys suggest me what can i do to fix it.
