Lessons learned from blood—be sure to take out unused batteries

During National Day, I was bored at home and started to organize things. It happened that the keyboard of the worker in the office was broken, and I wanted to find an old one to move it. Suddenly remembered that a gift from a customer had been left there, so I dug it out and tried it. Opening the unopened box, I found out that the battery inside was pre-installed in the keyboard.

The battery has leaked and cannot be removed, it is stuck in the battery compartment and cannot be removed. Looks like I can only find a way to dismantle it.

Du Niang casually looked for the position of the screw, and it turned out that the foot pad was a screw. There are 6 screws in total, of which the No. 2 foot pad is actually fake.

Then I found a hard card (I found a JD prepaid card ) Pry hard, be careful not to break the buckle. I have to say that the design of early Logitech is really , I have been very careful, or broke two buckles. Finally saw this extremely heavy galvanized panel. Then clean the battery compartment.

After cleaning, I installed the battery and tried it, turned it on, and it turned on. , and saved another 100 meters.

Then just turn on Bluetooth in a hurry and add new devices. There is a little trick here. When pairing the code, I actually had to use the keyboard to enter the number blindly. Then I waited for 2 seconds and there was no response. I pressed Enter and the pairing was completed. As for whether to press or not, I don't know.

During lunch time, I cleaned up the keyboard and reminded everyone that the battery must be taken out when not in use.

There are also brain-dead designers, why should the battery be placed inside the keyboard for the newly purchased keyboard? Don't you know that hoarders like to hide old goods for many years?
