On Power On, Screen of Samsung NC10 max brightness, cannot see user name to logon
Posted on 2010-09-02
This is a really annoying problem. About a year ago I bought a Samsung NC10 netbook from the Saturn store in Munich, Germany, and enjoyed it's convenient size, weight & battery life.
After a while I noticed the ambient light sensor would rachet the screen brightness up to the max when I turned the computer on.
This has the effect of whiting out the screen; nothing can be seen except for white light, certainly not the mouse pointer and my user name.
I therefore cannot click on my username to enter my password.
If this happens when I am already logged on, I can use the Fn key with the <Up> or <Down> keys to vary the brightness but if I'm not logged on these keys don't work.
Sometimes, if I wait, the Windows XP logon page becomes visible. OTOH it may not.
Generally closing the lid and opening it a little bit eventually works, or moving the computer to different light.
Sometimes the screen remains maxed out regardless. Especially when I need to do something urgently!
I'd obviously like to have the computer repaired or replaced, but during a move I lost the receipt.
Does anyone know how I can disable the ambient light sensor?
I reall don't mind adjusting the screen brightness myself.
