True, I booted my netbook up with my old 250GB Hard drive (the one that originally came with the system and still runs Windows 7 Starter) and checked these values. The DECIMAL (base-10) value you were taught in school is shown in parenthesis behind it, the (65535). Notice that the 0x0000fffe is the hexadecimal value that we talk about FFFE. So when you look at the Registry entry, it should look something like this:įeatureTestControl (bunch of space) REG_DWORD (some more space) 0x0000fffe (65535) So when you enter FFFE, that's HEX for 65,534 in base number. Just like in Decimal (base-10) when you hit 9, the next number just cycles to 0 and then you add 1 to the next digit place, so 9 + 1 = 10. The letters each hold a larger value by 1 than the previous, so F = 15. This means that each character can go from 0 to F.as in 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. Ok, in the System Registry, most DWORD (32-bit) entries use Hexadecimal notation. I'll continue working on this issue until I have a solution. Because of this, the brightness doesn't auto-change when you unplug the power supply and move to battery power and vice versa. You can get that app from Samsung's website for the N150 ( ).ĮDIT: Ok, so the Brightness keys work just fine, but something that still doesn't work are the Brightness sliders in Windows itself. You should have brightness control back if you have the Samsung Easy Display Manager software installed. Make these three changes and then reboot your computer. You can even do like apastron said and make a registry batch file to do this. HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\\0000 It says to include the following entries into the Windows Registry: Like all the other complaints above, it won't let you change the brightness of the backlight, so you drain your battery faster when not plugged in.įirst, I fully updated W-10, which included basically forcing me to upgrade to the latest Intel driver for this chip as shown above: 8.Īfter the restart, I found (via my desktop while the reboot was happening) this page: This driver is the one Windows Update is pushing onto my netbook in Windows 10. DTG: 15 August 2015 - 10:48 CDT (U.S.A.) (GMT-6)ĭriver: Intel(R) Graphics Media Accelerator 3150 (Microsoft Corporation - WDDM 1.0) Let me give you the particulars and then BOTH a link to the page I got this info from AND the steps I took to get it working in Windows 10. I have fixed this issue on my Samsung N150 netbook about 20 minutes ago. Maybe someone will listen and read this anyways here and finally fix this issue in a useful way soon though! You here at Intel will tell me the same now from your side that: " It's not your fault but Samsung needs to fix their tool here to work with Intel GMA drivers!", right?īut all this is surely _not_ satisfying us customers here in any way, if I may say so now. That's a real mess though as the Samsung support says: " It's not their fault with their EDM tool. 2230 as well !!!Įverytime you uninstall the Intel GMA drivers the EDM tool works again without any problems.īut without the GMA drivers you won't have any AERO desktop in Win7(圆4) and also not the highest possible resolution. _None_ of them worked so far to get the EDM tool still functioning _after_ installing any Intel GMA 3150 drivers later than. Meanwhile I tested various combinations of Intel GMA 3150 (圆4) drivers together with various Samsung's EDM tool editions. I can just verify that this problem exists in such a combination!Īlso got a Samsung NF310 netbook with Intel Atom N550 CPU, 2GB Ram and the Intel GMA 3150 graphics chipset. What is causing all of this and is there any way to use drivers less than a year old while still being able to control screen brightness via hotkeys? It's an important feature of any laptop. 1972 the Windows screen brightness slider works again, just like Samsung's EDM. There is a brightness slider in Windows 7 Power Options, and that also doesn't work after installing a driver later than. The problem is not just with Samsung's EDM program. Trying to adjust screen brightness using the latest Intel driver bring up a graphic produced by Easy Display Manager (EDM from now), but the brightness bars in said graphic don't move, nor does screen brightness change. It also requires a program from Samsung called "Easy Display Manager". Now, screen brightness on the N210 netbook is controlled by pressing Fn + Up and Fn + Down. The next driver available from Intel's site no longer allows me to change screen brightness, nor does anything newer. Following their advice, I uninstalled the driver and went back as far as version 8. This problem has been reported long ago elsewhere, at least in the forums. The problem is that after downloading recent Intel graphics drivers I can no longer change my screen brightness. I'm having an issue with my Samsung N210 laptop that has the GMA3150 graphics controller (Atom N450 CPU).
