Hi! Bros. I solved sleep problem with F09 DSDT
. But until now, I can't soled brightness when boot with only batterry. I followed the guide in FAQ many time, but can't solve it permantly
"My screen is black when I boot on battery, how do I fix that?
Well, you can turn it up by hitting fn and f3.
On boot, if you hit esc, it will enter BIOS. Here, turn it up with fn and f3, and then save the settings with F10 (I believe), and it will permanently eliminate this problem.
"
Here's what I do:
- Power on the laptop
- Press ESC to enter Bios(there are some options to choose), h still normal
- Press Fn+F3, then press F10, it take me to Bios Configuration.
- Press F10 again, save the setting and reboot(also tried reboot with out save bios setting, just press F10 once)
- Screen become black
, I have to manual press Fn+F3 to turn on screen
Can you show me how to fix. Thank all!
