The Lenovo IdeaPad 5 Pro 14ACN6 is a laptop computer with a 14" screen, AMD Ryzen™ 5/7 5000 U-Series Processor, 8GB/16GB of memory, webcam (with IR), dual-array microphone, stereo speakers, Bluetooth 5.1 and WiFi 5 or 6. (Discuss in Talk:Lenovo IdeaPad 5 Pro 14ACN6) Hardware It's possible that a BIOS upgrade might fix the problem but, as I said in an earlier comment, I'm reluctant to upgrade the BIOS on this laptop and there's nothing in Lenovo's release notes for newer releases specifically relating to battery firmware.Reason: Missing an accessibility section. My workaround is to manually store the desired thresholds in both the BAT0 and BAT1 subdirectories after which charging starts and stops at the expected values, despite the stored values for the start threshold being wrongly displayed as the value of the stop threshold plus one. It appears that the bug causes charging to start when the battery level drops below the threshold for BAT 0 and stop when it reaches the threshold for BAT 1. The thresholds in /sys/devices/platform/smapi/BAT0 remain unchanged. I haven't found a cure but I have come up with a useable workaround.Īfter issuing the command tlp setcharge 40 50 the charge thresholds are set in /sys/devices/platform/smapi/BAT 1 despite the laptop only having one battery. The problem appears to be due to a bug in the firmware. It also reports the wrong value (39) for the stop threshold which was set to 40 but the FAQ mentions that this is normal for the Edge series and the charge thresholds should work as configured. I note that tlp-stat shows values for BAT1 where I would have expected BAT0 because this laptop only has one battery, could this be relevant. sys/devices/platform/smapi/BAT1/force_discharge = 0 sys/devices/platform/smapi/BAT1/stop_charge_thresh = 39 sys/devices/platform/smapi/BAT1/start_charge_thresh = 40 sys/devices/platform/smapi/BAT1/state = none sys/devices/platform/smapi/BAT1/power_avg = (not available) sys/devices/platform/smapi/BAT1/power_now = (not available) sys/devices/platform/smapi/BAT1/remaining_charging_time = (not available) sys/devices/platform/smapi/BAT1/remaining_running_time_now = (not available) sys/devices/platform/smapi/BAT1/remaining_percent = (not available) sys/devices/platform/smapi/BAT1/remaining_capacity = (not available) sys/devices/platform/smapi/BAT1/last_full_capacity = (not available) sys/devices/platform/smapi/BAT1/design_capacity = (not available) sys/devices/platform/smapi/BAT1/temperature = 0 sys/devices/platform/smapi/BAT1/cycle_count = (not available) sys/devices/platform/smapi/BAT1/first_use_date = (not available) sys/devices/platform/smapi/BAT1/manufacture_date = (not available) sys/devices/platform/smapi/BAT1/model = (not available) sys/devices/platform/smapi/BAT1/manufacturer = (not available) +++ ThinkPad Battery Status: BAT1 (Ultrabay / Slice / Replaceable) * tp-smapi (tp_smapi) = active (status, charge thresholds, recalibration) Supported features: charge thresholds, recalibration Tlp-stat doesn't report any problems tlp-stat -b I've read the section 'Why is my battery charged up to 100%' in the tlp FAQ and the required kernel modules appear to be loaded lsmod | grep tp_smapi I've also tried setting the thresholds for both BAT0 and BAT1 in /etc/tlp.conf but that didn't have any effect. Charging always starts regardless of the charge level and continues up to 100%, If I'm interpreting the man page correctly it should be sufficient to use the command tlp setcharge 40 50 followed by tlp start to activate charging when the battery level drops to 40% and stop charging at 50% but this isn't happening for me. I have a Thinkpad Edge E50 running MX Linux 21.2.1 which I'm trying to configure for optimum battery life. ![]()
