Two star doc for backlit keyboard not staying on. Has a setting in the BIOS to set Keyboard Lighting Timeout to Enabled or Disabled but it doesn't work. I disabled the time out and it worked the first session but continued to time out afterward. Set it and reset it again and nothing. My BIOS is version v1.06 so I downloaded the v1.07 update but the update procedure is unclear and not documented for this model anywhere on the model page. Backlit keyboard a big reason for purchase...UPDATED: 6 MAR 2020The backlit keyboard stays on if its plugged into power and has the bios setting disabled but if its on battery it times out no matter what the BIOS setting. Tuned off all the power saving features in Windows 10 and the keyboard still timed out on battery even with the BIOS setting disabled.
