Critical problem with power management CentOS 7.2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Thinkpad T410 running CentOS 7 with the Mate desktop (Gnome 3 is too demanding on video capabilities for this hardware)

Under CentOS 7.1 - the laptop would sleep when I closed the lid.

It no longer does. I can tell because the laptop remains warm when I close the lid now, mail filters in Thunderbird run when the lid is closed, and it doesn't need to re-establish wifi when opening.

This is dangerous because thinkpads cool through the keyboard.

The battery usage monitor also no longer works. It shows 99% battery even as the laptop starts giving its warning beep that the battery is exhausted and it is about to shut down.

Anyone know what broke with the update to 7.2 and how to fix it?

No 3rd party kernel modules are involved.
