【対策作業】使用中に電源が切れてしまうノートパソコン、原因はコレでした

I diagnosed a laptop that was shutting down during use. The results indicated a problem with the battery (there was also a problem with the internal battery control). I could have simply replaced the battery, but that would have been quite expensive. So I decided to disassemble it and continue using it with an AC adapter. Actually, laptops can be used without a battery. Similar problems have been around for a long time, and it's common to operate them without the battery. In the past, battery packs could be easily removed. But these days, there are more internal batteries, and more devices require disassembly like this. (lol) Please use this as a reference if you'd like.
