To confirm the currently installed amount of RAM, check the POST screen, BIOS, or System Properties window

Magnetic hard drives have drive motors designed to spin magnetic platters, which are read by movable drive heads. In contrast, SSDs do not have moving parts. Because there are no drive motors and moving parts, the SSD uses less energy than the magnetic hard drive. Flash memory chips manage all storage on an SSD, which results in faster access to data, higher reliability, and reduced power usage.

Yeah you definately do not plug up a laptop when you are about to work on it think about guys, kind of a bad idea. OBVIOUSLY if you are about to repair it don't you think you would already know the battery is ok. If not maybe you shouldn't be working on it!

ya! there is wrong ans...

I made a 100% on this. 1, 10, 12 are def wrong. 12 is def a CPU issue.. This is common sense. The answer for 1 is laughable let me know where you can get one of those 2TB SSDs. Solid state drives reduce power usage.
And 10 is:
The hard drive was not connected properly.
The BIOS does not recognize the new hard drive.
