No green light, turns on and says the battery is charging and is in normal condition. Battery was recently replaced about a month ago and it charged and held a charge and would recharge however now it won't charge past 1% yet it says it is charging. This just randomly happened today and wondering if anyone has experienced this? I want to see if it's something else before pulling the trigger on a new battery.

Re: M1 Pro 14” MBP Battery issue
Check the usual esd tvs diodes on the smbus lines on the battery connector.
What are the voltage readings to ground of each such smbus line on the battery connector? -
Re: M1 Pro 14” MBP Battery issue
Update:
We had a bad battery in the back and decided to install that as a test and it did detect it as faulty. We removed it out the other battery back in and now it decided to start charging. I think this reset the system and after the reinstall battery is charging. No idea why but we are going to keep the bad battery on hand just for this purpose. I also read online this is common in these macs due to Monterey 12.4 and above. I hope they have a patch coming.sigpic

I bought a Vostro 3400 motherboard (LA-K033P) to upgrade over my damaged Inspiron 5593 (LA-J091P) board. Everything else is ok except for the battery. This battery I am using now is already a replacement one since I disposed of the bloated original one. Back in the Inspiron 5593 motherboard, the battery charges fine and is identified just fine. However, with the upgraded motherboard, suddenly the replacement battery is labeled as "Not a dell battery". When I borrow a similar battery from my colleague (which did not have replacements yet), it is identified and charges just fine.

Hello,
it's not a laptop/desktop related question but I figured that someone here will have the right knowledge.
At work we use a few Aldebaran(now Softbank/United Robotics group) Nao Robots which they use some custom 6S li-on battery packs.
Nao robots tends to draw from the battery even if they are shut down, and the BMS tends to be a little aggresive, if the pack stays on a turned off robot for 3 months it's gonna lock and will refuse to charge.
Now, I have noticed a few things.
The "dead" battery, while connected to charger and NOT Charging will... -
Hi
Acer A515-43
LA-H801P
Fail: Does not charge battery, has low voltaje on connector.
Laptop didn't want to turn on, only charge led blinked.
I found PQB5 (mosfet high battery charger) in short, voltaje in +12.6V_BATT was 19 v ...
I changed it, changed PQB6 too and now battery charger voltage is 4.4V but battery is 3 cell, 11.25v, then is very low to charging.
Laptop turns on without battery and works fine, but with battery turns on and turns off inmediately, I suspect battery bad but I don't know... -
Hi everyone,
I'm having an issue with my Lenovo ThinkPad P43s. The laptop does not power on when the internal battery is connected, but it works fine on AC power alone (battery disconnected). Once the battery is reconnected, the system becomes completely unresponsive — no lights, no fan spin, nothing.
Here's what I've tried so far:- Power/EC reset (held power button for 60 seconds with battery and AC disconnected)
- Booted successfully on AC power only with the battery disconnected
- Visual inspection of the battery — no swelling, burn marks, or connector damage

Hello, I have issue with Dell Inspiron 3542.
Motherboard marking:
The laptop works just fine (on battery and power supply) and doesn't cause any problems, except those described below:Code:Cedar_Intel-MB 13269-1 PWB FX3MC REV: A00
- The first problem is that the RTC/CMOS battery self-discharges after about 2-3 weeks after installing a new battery. I have been installing different batteries (GP, Duracell, Energizer) and the problem still exist.
- The second problem is the LAN network card (Realtek RTL8106E), which is not detected at all in Windows. The BIOS is
