Without the battery manager I can't triple the battery life span. So if you consider it bloatware, sure, why not eject it and exchange this for that?
The network item lets us turn on/off the wifi and make connections. If you don't use WiFi, then eject that.
-> It goes on and on so research what each does and decide.
I think I see this when a desktop user steps onto a laptop with all these management tools. They are used to clean desktop installs where we didn't care about battery life cycles and such.
I'm pretty sure I don't use any of these, but I don't really trust my gut with the more obscure inner workings of computers so I decided it would be best to ask someone who'd know.
In case it matters, I'm using a Samsung laptop running Windows 7
