Ethernet connection disconnects in battery mode

Post by salil19 » Mon Aug 27, 2018 1:53 am

I have installed Linux Mint 19 (Tara) (kernel 4.15.0-32-generic x86_64) with XFCE desktop on my Lenovo Y50-70 laptop.
The laptop has a Realtek RTL8111/8168/8411 PCIE Gigabit Ethernet Controller (driver: r8169 v: 2.3LK-NAPI port: 3000 bus-ID: 09:00.0
IF: enp9s0 state: up speed: 100 Mbps duplex: full)

The ethernet connection works fine when my laptop is plugged in to the power source. But the ethernet connection disconnects
as soon as I switch to the battery mode. I tried restarting the newtwork manager (service network-manager restart) but it does not help.

Can you please help me resolve this issue.
