Dell (Vostro V13) laptop < 2 years old; Win 7\n\n\n\nBrightness adjust with keyboard quirky\n\n\n\nRecently, pressing fn + up/down (brightness) keys gets random results. The\nup key dims and then reverses and brightens. Key press again, nothing\nchanges. Key press down brightens or dims intermittent. Strange random\nbehavior.\n\n\n\nAdjusting using the display brightness slider via Power Management works\nfine (normal)\n\n\n\nI fell back to previous display adapter driver, no help; reinstalled latest\nagain still no help. Scanned for keyboard new driver version, none found.\n\n\n\nHardware > Keyboards. there's a USB Intellipoint keyboard listed - I have no\nsuch thing. I don't know if that's the conflict. Rt Click / Disable is not\nan available choice. I don't know if that's a new hardware item or if it\nwas always there. Uninstall is an option - I'm holding on that.\n\n\n\nGoogling for this is crap, but I did follow an advice to go into Bios and\nsee if the display is set to auto or manual. I'm not comfortable in Bios,\nbut did. This laptop has no such display entry in the Bios as described\non-line (for a Sony). I reinstalled the Dell V13 Bios update, no help.\n\n\n\nSomething else online seen then tried. During boot hold fn and tap the\nup/down keys. After Windows loads, that does seem to change the fn+up/down\nresponse, but it's still not right.\n\n\n\nLastly, the fn+vol up/down is perfect. The up/down keys are perfect when\nscrolling web pages/docs. Don't think it's the physical keys associated\nwith this brightness anomaly.\n\n\n\nI discovered this brightness issue with my kid's laptop; now I'm blamed!\nExact when after what is unknown. Stumped, thought of you.
