MacBook Pro with battery removed: strange behavior, no serial number

My MacBook Pro's battery was swelling so I had to have it removed. Since the store that did it doesn't stock this battery, I'm now using the computer without a battery until they can order one.

The computer is out of warranty and Apple quoted me a ridiculously high price for a replacement, so I had to go to a 3rd party repair shop.

I've noticed a few things, some of which I know are normal, but others I'm not sure of.

  1. In "About this Mac", the Serial number shows as "Unavailable". It used to show up fine before the battery removal.
  2. I booted up in Diagnostic mode (holding down D during boot) and it said this: "NNN001 - A serial number was not detected. The computer requires service."
  3. The computer runs very slowly, though I've heard this is normal and it's to prevent drawing too much power from the power adapter when no battery is present.
  4. In System Preferences, when I go to "Trackpad", it keeps looking for a Bluetooth trackpad and says "No trackpad found". The options to change gestures isn't there, even though my built-in trackpad is working fine, gestures and all. I just can't change anything.
  5. In "Mouse", it also doesn't give me options for "Natural scrolling direction" or tracking speed as it usually would (even if no mouse is connected), but rather searches endlessly for the non-existent Bluetooth mouse.

So I'm wondering how much of this is normal for an absent battery. Is the "no trackpad found" thing related to the serial number missing? Why is the serial number even missing, will it "come back" once a new battery gets installed? Or will I have to use the Blank Board Serializer tool to re-set the serial? Will that also fix the trackpad issue?

Has anyone here used a MacBook Pro without a battery? Did any of this happen, and did these get resolves by installing a battery?

Could the repair shop have messed something up while removing the battery?

The shop has told me that they can't order a genuine Apple battery because apparently Apple doesn't sell them. So it's going to have to be a non-genuine battery. Is that even a good idea?


Answer this question I have this problem too

Is this a good question?

It’s probably lost the setting for your network and printer too. It may lose the time and date if you are not connecting to the internet. Don’t worry about the anomalies until after you have the new battery in, charged it up and reset your preferences. It’s a little bit of work but you can replace this battery without taking it to a shop. Here’s how:

You can get just the battery or the kit which includes all the pessary tools to do it:

Thanks! It seems my network and printer settings are still there though. Do you think these issues will be resolved once I install a new battery, will the serial number return?
