As opposed to taking the part out of a Framework laptop, shipping it back to the repair center for weeks, and then reinstalling it when it comes back?

Or if time is of the essence, ordering the brand new part to skip the repair process and then installing it yourself when it arrives later?

Contrast this with the amount of time my coworker spent hauling his laptop charger everywhere and obsessively topping up his laptop battery while traveling because the battery drain during sleep was a problem at that time. This added extra wear and tear on the battery, of course, but I guess he could replace it himself?

You just order a new key, and install it. And not have the downtime. (You can remap key or use an external keyboard.)

And yeah, replacing the battery is easy. Not a Framework, but I replaced a laptop battery some years ago, was glad I had that option, because lithium battery lifetime always decreases eventually.

I’m old enough to remember when many phones and some laptops had removable batteries. Switch to a spare, and boom instantly full, you didn’t need to tether it to a wall.
