E320 - screen brightness changes randomly

Hi there,

I got my E320 few moths back and I am very happy with it, but one thing bugs me sbout it. Sometimes (doesn't matter if AC adapter is connected or not) screen brightness changes randomly and fn keys for changing it stop working. Sometimes it recovers after a while and sometimes I need to reset it by sleepmode or reboot. Is there something I can do to avoid this, please?

Hi Brejlounek,

I would suggest check and update BIOS and power management driver. If problem remains, please contact local lenovo for hardware test
