Hello, I've had this Alienware 15 R4 for about a year and today the battery gets swollen just couple of months after the warranty, so I tried to disassemble it to take the battery out. After getting the battery out I reinstall all the parts, I tried to turn it on but it gave me the red and blue on the alienware logo. I think to start this laptop you have to install a battery. Do you guys know how to use this laptop without battery.

Thanks
