Hi everyone,
I'm not looking to upgrade anything right now but i would like to understand how my laptop's power supply works. I've been getting into PC gaming over the last couple years and my curiosity about computer hardware has been growing along with my game library
The way I understand things (and feel free to correct me where I'm wrong) is that a laptop's power supply is that big ol' brick thing in the middle of the power cable. I've seen them come in 65W, 90W, and a few other options depending on your particular rig. I'm pretty sure I understand why an underpowered *desktop* will have issues (decreased performance, increased heat, greater risk of failure as certain components draw the limited power away from other things that also need it, etc.). But desktops don't have a dedicated battery like laptops.
So. Why would having too little wattage in a laptop's brick thing leave your laptop underpowered and at risk of damage/problems? Laptops always have a battery -- why does the cable that charges the battery make any difference if the components are all relying on the battery for power anyway? Shouldn't the battery be the deciding factor of how much power your PC can draw on while the cable simply governs how fast it can charge?
Thanks in advance for explaining this to me!
