hi guys so i have this really strange issue i have a dell inspiron 1564 laptop nd whenever i enter bios mode to install os or anything bios related my laptop shuts down with the sound of click because of it i cant do anything bios related like installing a new os or repairing my windows this only happens when i enter bios mode not when i use windows i tried updating my bios but couldnt because i use my laptop without the battery nd it said i need my laptop battery above 15 to upgrade the bios nd yes when i try it install new os it gives me this "disk read error" i tried rearranging those booting options but nothing helped .
