When not connected to the power brick, it would partake in this peculiar boot-loop sort of thing where it would POST (power-on self-test) and then shut down, and then repeat the process multiple times before finally booting into Windows. And the fun and games didn't stop there - Once Windows had been successfully awakened, the time was the same as when I'd last powered it off, requiring me to go into the date and time settings once logged in and synchronize it with time.windows.com. I didn't know what was causing this and I ignored it for awhile, but eventually I decided that enough was enough and that I was sick of sitting there and Kubrick-staring at my laptop while it performed this stupid little dance. So I did some digging on the subject and found out, through the supreme and everlasting power of Reddit, that this malarkey was likely due to a dead CMOS battery. Upon pantsing the Blade, I saw a battery that looked just like this one and confirmed via YouTube that it was indeed the CMOS battery on this device. So I decided to pick this up and install it onto the laptop's board the next day, and voila - She fires right up no matter what and the clock is accurate each time. This battery seems to work quite well and I'd recommend it to anyone in a similar conundrum to myself.
