T480 unable to wake from its sleep

2018-10-28, 12:09 PM

Hi all, i recently started using Lenovo Vantage's Battery Charge Threshold so that my laptop is plugged in and not charging. However, when it goes to sleep, i can't wake it, yet i can wake it from hibernation. The only way to wake it from sleep is to remove the power plug. However, when i turn off Battery Charge Threshold, i am able to wake my laptop from its sleep. Anyone has any solutions?

The problem seems to be fixed with a BIOS update 1.18 or newer. If Lenovo Vantage doesn't find it, download and install manually from the website.
