Hi guys,

I have a DELL Vostro 1500. I used to have trouble with the screen as the backlight would just shut down when I tried to increase the brightness. I got it repaired and the guy told me they had to change some Voltage Regulator somewhere in it. I only realised later that after the repair I couldnt vary the screen brightness at all. Through the keys on the keyboard and even in the setup when I reboot. The brightness meter moves around when I change it but the screen doesnt change. Also Ive left the country where I got it fixed and I have no way to get the Laptop back to that guy. Any help will be greatly appreciated! Thx!

Dell Vostro 1500, Windows Vista 32-bit SP2, Intel Centrino Duo 1.86ghz, 160GB HDD, 256MB Nvidia 8600M GT, 3GB ramThe circuit was likely replaced, so there is no controls. He likely found a regulator that would sustain the load and voltage required and soldered a tap off of the existing power. By doing so would eliminate all CONTROL of brightness and make it a constant brightness as you describe.

Only way to fix this would be to undo the rerouted circuitry if possible to do so without damaging the display or laptop further.Thanks Dave. I will try and find a TECHNICIAN to see if he can do that for me. The thing is it doesnt really bother me that MUCH, but when i go on battery power it reduces the battery DURATION adn battery life. My battery went from a duration of 2 hours to 5 min in 8 months time. And i dont want to buy a new battery if its going to destroy that one as well. Thanks for your help! Yah I can see the frustration in the lack of mobility without an outlet handy. You can also try to conserve power in power options by telling the hard drive to spin down when not active etc, and some NEWER laptops have an energy star adjustable stepping feature to underclock the cpu when idle to conserve electricity in the bios configuration.
