After playing the game in the evening, the battery was 18%. I plugged in the data cable. By the way, it was late. I quit the game and pressed the steam key - Power - Shut down. After charging for about an hour, I unplugged the data cable and turned off the light to sleep

The next day, I couldn't turn on the machine. I plugged in the charger and turned it on, thinking it was OK. When I saw 100% full power, I unplugged the charger and the screen went black

Now the charger must be plugged into the machine to play normally!!!!!

At present, it is useless to re insert and unplug the battery after removing the back cover,

The BATT 100% and charger logo can be seen on the power on performance interface

And there are 99% prompts for diagnosis under the battery, and the figure of 0 watt

Need your help

14号签收，17号晚上打完巫师3看电量18%，顺手插了数据线，顺便看时间很晚了就退出游戏按steam键-电源-关机，充了大概一个小时就拔开数据线关灯睡觉

第二天就开不了机，插了下数据线开机了以为没事，看到满电100%拔开就黑屏了

现在必须得充电器插着开机才能正常游玩！！！！！

装备问题等：目前sd卡刚到货，扩展坞没买

14号晚上整的系统，第二天15号整浏览器steam++并且下载游戏 第三天不知道玩啥，第四天群友说的巫师3就下载了打了2小时

目前排查：进行拆机后重新插拔电池多次没有用，拔开电池插充电器开机，在性能5级图标看不到BATT 之类的

插电开机能看到BATT100% 和充电器标识

并且电池下诊断那里有99%的提示，和0瓦的图示

The Nintendo was shipped to me completely disassembled, so I reassembled it and replaced the top display (the flat panel was visibly damaged).

I charged the Nintendo and the charging LED lights up correctly, but after charging it for over an hour, the Nintendo won't turn on for any reason.

When connected to the power supply, pressing the power button turns the charging LED off and back on within a second; no flashing displays, no sound, nothing.

However, when running on battery power only, no LED lights up, not even for a moment.

I think I can rule out damage to one of the displays, since from what I know, if one of the two displays is damaged, a white flash should be visible on one of the displays.

I checked fuses F1 and F2, and they're OK.

I've unplugged and replugged all the flat cables and the wireless card, but the problem still persists.

The only oddity is the battery voltage. Specifically, when I insert the battery into the contacts, it reads 4.1V correctly. When I press the power button, the voltage drops to 0.85V and stays there until I remove and reinsert the battery, returning it to 4.1V.

I removed the SD card, and there's no play in the card slot.

I should point out that there's not the classic blue LED and black screen problem; no LEDs light up, except the charging LED.

Can anyone tell me what the problem might be? I've been stuck in this situation for days now, and there doesn't seem to be a way out.

Thank you all for your time.

Right joy stick gets stuck rising from 20% to 70% up, then when you use the stick it resets and rises again. I would send a video but I don’t know how.

Recently, I've decided to pick up my New 3DS to play some Picross, and noticed that it wouldn't power on. I tried charging it over night, but it still wouldn't work, I assume it never charged despite turning on the charge light.

I checked with a multimeter and the battery only showed 1.2v, so I'll assume it's dead dead.

As I've been waiting for a new battery to arrive, I've been playing it with a power bank attached.

Today, it arrived, and the 3DS doesn't turn on with it. It sees the battery, it shows it's fully charged, but when I unplug the power bank, it immediately shuts off.

I don't want to assume I have a new dead battery just yet, but I haven't opened it just yet.

Pertaining to the USB-C mod, it's only become an issue now, despite around a year of using it, it charged the battery just fine.

Edit: Here is a picture of my board and mod. It's not the best, but I'll get a better one when I can

Edit 2: I think I have found the issue... Those cables aren't meant to be crimped, are they?...

Edit 3: I have tested what I presume to be both F1 and F2 fuses (it's the ones surrounded) and they appear, at first glance, to be nominal. There's a slight voltage drop in the F2 fuse (from 4.3 to 3.7 volts), but not being sure about nominal voltages, I'm assuming they're fine.
