I have a MacBook Pro late 2011, it's running Ubuntu 20.04 LTS. The issue comes when I look up the battery percentage. It says that it is on 50%, but this MacBook has some LEDs on the side which indicate the battery level. But when I press it all LEDs come up, and in the system it only says 50%. Can someone help me?

Edit: So, i just ran this command upower -i /org/freedesktop/UPower/devices/battery_BAT0 PS: I ran it without being in the power.

This was the output: native-path: BAT0 vendor: SMP model: bq20z45 power supply: yes updated: sáb 14 ago 2021 16:22:54 (83 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: discharging warning-level: none energy: 37,3942 Wh energy-empty: 0 Wh energy-full: 41,9823 Wh energy-full-design: 63,1815 Wh energy-rate: 16,3374 W voltage: 11,376 V time to empty: 2,3 hours percentage: 60% temperature: 22,9 degrees C capacity: 66,4471% technology: lithium-ion icon-name: 'battery-full-symbolic' History (charge): 1628968965 60,000 discharging History (rate): 1628968973 16,337 discharging 1628968971 16,545 discharging 1628968969 16,283 discharging 1628968967 15,253 discharging 1628968965 15,111 discharging

Could you [edit] your question to include the output of this command:`upower -i /org/freedesktop/UPower/devices/battery_BAT0` ? This will make it much easier to answer your question using math that you can verify.

Of course. I did it.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
