Re: Problem with the new battery for Lenovo B590
Is the battery an original ? Sounds like the battery is a compatible model but the logic board wants to see some special token from the battery pack.Comment

Hello! I'm here to look for solutions to reset the EEPROM memory of a Lenovo E540 battery of 62Wh and 540mAh. I even bought a new one on the market (aftermarket BTIBM30) because I couldn't find an original one but it doesn't work. The laptop sees the percentage but blocks the battery charging probably because of the Chinese BMS. In the bios I don't have an option for the battery and I didn't find an older version (v1.57). I replaced the Lenovo BMS with Chinese cells but in windows it doesn't read the battery percentage and says it needs to be changed. I have 12v between D and the red wire....

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 a customer that brought this laptop in after replacing his battery. He said his original battery charge was not lasting long, and after replacing the battery with one purchased from iFixit, the charging worked for about 30 minutes and then stopped, and the battery is no longer detected by windows.
This laptop powers on when the AC adapter is connected, and my USB-C multimeter shows current being used with both ports, but the charging light does not come on, and in Windows the battery icon shows an X as if there is no battery present. If I disconnect the AC adapter,...
