FAQ
TL;DR: Lenovo G710 showing “Plugged in, not charging (1%)”? “A new battery should have enough energy,” typically ~50% on arrival (≤30% by air). Most cases trace to battery–laptop communication or a wrong battery model/ID. Use BatteryMon and verify FRU L11S6Y01. [Elektroda, Dydelmax, post #17383814]
Why it matters: This FAQ helps Lenovo G710 owners quickly diagnose and fix no‑charge symptoms without costly guesswork.
Quick Facts
- Correct OEM pack for G710: L11S6Y01 (3INR19/65-2). Mismatched FRU IDs can block charging. [Elektroda, Axel152, post #18247226]
- Common trap: L11M6Y01 Y480 batteries are sold as “compatible” but the G710 rejects them. [Elektroda, Axel152, post #18247226]
- Use BatteryMon: Info → Battery information to confirm detection details before replacing hardware. [Elektroda, Dydelmax, post #17383745]
- If both old and new packs read wrong, suspect laptop‑side communication (SMBus/EC) faults. [Elektroda, Dydelmax, post #17385363]
Why does my Lenovo G710 say “Plugged in, not charging (1%)”?
That message appears when the system sees the adapter but will not accept charge from the pack. Causes include SMBus communication faults on the board, bad battery ID, or a non‑compatible FRU. If both your old and new packs misreport details, suspect the laptop, not the batteries. Confirm detection with BatteryMon, then try a known‑good, correct FRU pack. If misdetection persists, seek board‑level service for the battery interface or EC. [Elektroda, Dydelmax, post #17385363]
Will a brand‑new battery have charge out of the box?
Yes. A new battery should arrive with usable energy, typically around 50% state of charge. Air‑shipped lithium packs may ship at 30% or less. The laptop should power on briefly on battery alone. Zero runtime from a new pack points to detection issues or the wrong FRU. Replace with the exact L11S6Y01 model and retest. “A new battery should have enough energy to run the laptop.” [Elektroda, Dydelmax, post #17383814]
Which battery model actually fits the G710, and which “compatible” one should I avoid?
For the Lenovo G710, use battery L11S6Y01 with marking 3INR19/65‑2. Avoid L11M6Y01 units marketed for the Y480. Many listings label them “compatible” with G710, but the laptop refuses them. Symptom examples include “battery not recognized” and charging stuck at 1%. Confirm the FRU printed on the pack before buying. If you already have the wrong pack, return it and source the correct FRU. [Elektroda, Axel152, post #18247226]
My G710 shuts off immediately when I unplug AC. What does that indicate?
If the machine dies the moment you pull AC, the battery is not powering the board. That often means the pack is not detected or the battery communication path is faulty. Try the correct FRU pack and retest. If both old and new packs fail identically, the fault is in the laptop. Seek service for the battery interface or embedded controller.

How do I confirm if Windows is reading the battery correctly?
Install BatteryMon and open Info → Battery information. Check Manufacturer, Designed capacity, and Status. Mismatch or nonsense values mean the system is not reading the pack properly. Capture screenshots for each battery to compare behavior. How‑To: 1. Install BatteryMon. 2. Run Info → Battery information. 3. Save screenshots for old and new packs.

Where can I safely download BatteryMon?
Download BatteryMon from the vendor’s site. Go to https://www.passmark.com/products/batmon.htm and click Download now. Installing from the manufacturer reduces risk and ensures you get the latest build. This is the source recommended in the thread. [Elektroda, Dydelmax, post #17383804]
Can a software or EC reset fix this without repair?
Yes. One case resolved after the system displayed a prompt to reset charging logic, then rebooted automatically. After that reset, charging worked normally. Accept such prompts when they appear. If you see none, a full shutdown and restart can still refresh the controller. “It reset itself ... and it started working.” [Elektroda, popsutaamica, post #17393004]
Should I test with a different AC adapter?
Yes. Testing with another known‑good adapter of the correct voltage and wattage rules out a weak power brick. A failing adapter can hold the laptop on, yet never deliver charge current. If a second adapter behaves the same, focus on the battery and laptop interface. [Elektroda, Dydelmax, post #17383804]
Windows misreports my battery’s model name. Is that a problem?
Incorrect battery model reporting is not normal. It points to communication problems between the system and the pack. That condition also explains “plugged in, not charging” at 1%. Confirm with BatteryMon. If both packs misreport, plan for board‑level diagnosis or service. [Elektroda, Dydelmax, post #17385363]
What does “Both batteries are incorrectly detected” actually mean?
It signals a laptop‑side fault, not two bad batteries. “Both batteries are incorrectly detected by the laptop” is the key clue. The SMBus lines or the embedded controller may be at issue. Repair targets include the battery connector, EC firmware, or related circuitry. Proceed to service if reseating and correct FRU testing fail. [Elektroda, Dydelmax, post #17385363]
How do I tell if a replacement pack is the wrong FRU for G710?
Check the label on the battery for L11S6Y01 and 3INR19/65‑2. If you see L11M6Y01 or Y480, it is the wrong pack. Windows may display “battery not recognized” or refuse charging. Sellers sometimes list Y480 packs as G710 compatible. Return and order the exact FRU instead. [Elektroda, Axel152, post #18247226]
I replaced the battery and still see 1%. What should I try next?
First, reseat the pack and lock the latches firmly. Then open BatteryMon and verify the battery fields. If values are missing or wrong, the laptop is not communicating with the pack. Try a verified L11S6Y01 pack. If symptoms persist across packs, schedule service for the battery interface. [Elektroda, Dydelmax, post #17385363]
