Genuine Lenovo Battery Not Attached, Lenovo ThinkPad Yoga

2014-01-20, 14:54 PM

I am having a message that says "Genuine Lenovo Battery Not Attached" message that appears after Windows 8.1 starts up. A similar sort of message appears before even Windows boots up, and I need to press the 'Esc' key in order for Windows to boot. This seems to have happened after a recent Windows update. I have uninstalled an reinstalled the Lenovo Power Management Driver but it does not appear to have fixed the issue. My BIOS is the latest version.

 

This issue is on my Lenovo ThinkPad Yoga S1.

 

Any assistance is appreciated.

Solved! See the solution

Hi,

 

Welcome to Lenovo Community Forums!

 

I’m sorry to hear that your Lenovo ThinkPad Yoga is displaying a message stating “Genuine Lenovo Battery Not Attached”.

 

I would suggest you to perform Flee Power – remove the battery and any other peripheral device connected to the computer. Hold the power button for 10-15 seconds and then connect the battery and AC adapter to turn ON the computer.

Get into BIOS and load defaults, save and exit.

 

Open Device Manager and under Battery Look for Microsoft ACPI Compliant Control method Battery, right Click on it and uninstall it, Restart after uninstallation.

 

Please let me know the happenings!

 

Best regards,

Mithun.

The thinkpad yoga has an internal battery and it is not user replaceable. You can detach the power adapter, and press the reset button on the bottom of the laptop. The reset button is within a tiny hole around the fan vent. You need to activate it with a pin.

I found where the little tiny hole for the reset button. What does the Reset button actually reset? Will I need to reinstall the Windows OS or anything like that after the reset?

Reset simply does a circuit discharge, it doesn't wipe anything off your hdd.

Hi,

 

Does the machine need to be powered off before the reset pin hole is pressed?

 

Cheers!
