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.

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!

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?
