i don't know that laptops graphic card but possibily you can adjust brightness via your graphic cars software ... for example if graphic card is nvidia you can find brightness feature at nvidia control panel - display - adjust desktop color settings - ...

My laptop has a light sensor on it. In order to manually adjust the brightness (for me it is fn+f9 and fn+910) I must first turn off the auto-adjusting brightness which is fn+f11 for me.
