ThinkPad P1 Gen 2 Genuine Battery Not Supported

[Shisui2010]

I got a genuine Lenovo battery for my ThinkPad P1 Gen 2 notebook from Encompass, model number 20QTS00W00. 5B10W13953 is the genuine battery part number. However, the computer fails to identify this real battery and displays "The system does not support the installed battery, so it cannot be charged. Use the proper Lenovo battery for this system to replace the current one."

My original battery has been completely depleted. My original battery can be detected when I insert it, but it cannot be charged.

The battery, in my opinion, is the issue. According to Encompass, the only battery that works with my laptop is the authentic one. And the warranty on my computer is up.

Welcome to the forum.

Sorry to hear about the trouble with your new battery.

There are a few things to check:

• Did the battery come in a Lenovo-branded box with warranty / instructions paperwork?
• Does the serial number printed on the battery match what is detected by battery monitor programs? If Lenovo's tools (Vantage) fail to detect the battery completely, perhaps tools like BatteryInfoView still can.
• Assuming both things above check out (which indicates the battery is original), then the conclusion would be it is somehow faulty, and Encompass should replace it.
• If the computer is still in warranty - perhaps the battery itself is too? These are sometimes shorter than the warranty on the laptop itself, but I would check. If it is in warranty, Lenovo should replace it free of charge.

Good luck!
