Raspberry PI PIXEL on old laptop

Installed the raspberry PI os PIXEL on an old laptop

https://www.raspberrypi.org/blog/pixel-pc-mac/

laptop:

old acer aspire one:

• atom N570 cpu, 4 core 1.66GHz
• intel graphics
• 1 G ram
• 250 MB HD
• 1000x600 screen
• wifi

almost the same specs as a Raspberry PI 3!

initially works fine, except BATTERY DIES, even when lid closed!

solution:
install the laptop components of debian to manage power properly:

sudo apt install laptop-mode-tools

then run the control utility (as root)

sudo /usr/sbin/lmt-config-gui

so far working well ...
