[Q] how to adjust screen brightness on a laptop - Windows 8 General

after i re installed windows 8 on my samsung i5, series 5 ,a i cant adjust the screen brightness.how should i go about it ,please help?

which is your laptop
Hello
Can you please post your laptop model number here??
Shortcut keys varies from model to model
Mostly iys Function + Some F1-F12
See your keyboard.it will be having a sun star symbol....

Did you reinstall the drivers for Intel HD and possibly your GPU?
On Device Manager, under display adapters, if your GPU is listed as standard VGA graphics, it means Windows is using the generic driver.
I had the problem and was confused why I couldn't use the brightness keys, but installing the official drivers did the trick for me.

[Q] Win8 Pro Rotation Problems

2GB DDR3
(this may have to do with it....) its a x64 processor with x86 installed.
Multi-touch points

When i flip the tablet, the screen doesn't rotate. Its got the sensors to allow it to do so.

32 bit runs on both 64 and 32. Probably not that. Do you have access to your drivers if the tablet has any. This could be the problem.
Yeah. First advice is to make sure you don't have the orientation lock enabled. Open the Settings charm (anywhere, including desktop, is fine), then click/tap the Screen button in the bottom right (the one used for changing the brightness). Above the slider bar is a button that toggles whether or not the screen orientation is locked.
If that doesn't work, double-check that you've installed the drivers for your tablet. They should be available from the OEM's website. Generally, Win7 drivers will work fine.

I can not switch between my two video cards in windows 8.1.

I have a HP Pavilion dv6 6c80el that mounts two video cards: an Intel 3000 graphics and a dedicated AMD 7690M XT 2GB . I installed Windows 8.1 and I can not configure the video card to use for each application as I did before with 7. Now with 8.1 when I click with the right button on the desktop and then I click on my switchable graphics cards comes out HydraGrid in the catalyst control center, which has nothing to do. How do I fix this? Using 3D modeling programs like 3dsmax that I run with the intel and work is impossible.
I'm afraid that Windows 8.1 does not support double graphics cards, is that it? Is there a way to solve?
Have you tried installing the OEM drivers and software for your computer? Win8.x should handle Win7 drivers just fine. OEMs (like HP) pre-configure a bunch of software in their Windows images, and when you install a new version you lose a lot of that. You can usually get it back by installing the stuff from the OEM's website, though.
Alternatively, it's probably possible (in the BIOS/UEFI if nowhere else) to disable one GPU in favor of the other. Turning off the Intel graphics entirely will cost a bit of battery life, but will mean that the more powerful chip is always used and therefore you'll be able to run graphics-intensive software.
Thanks for the reply but more or less I was able to solve this way:
I uninstalled drivers and software driver from Device Manager, and then I did a clean with driver sweeper. After that I rebooted and installed the drivers offered by HP (not those of AMD) and so it seems to have solved. I can configure the graphics chip to use for each application; sometimes throws a tantrum when I open the catalyst control center, but I'm happy that it works and is able to use to the maximum the pc.
Glad to hear it. Yeah, you can get better performance if you use the newest AMD drivers, but for weird integrated hardware like a lot of laptops have, you should get your drivers from the laptop OEM unless you're just going to run exclusively on one graphics card or the other.
I tried installing the latest drivers from AMD website (if I'm not mistaken are the 14.4 version and then there is 14.6 which is in beta). The problem is that by installing the official drivers AMD, you do the example of 14.4, after installation if I go into device management I recognize my video card like an AMD Radeon 6700m series; and at that point I can not change most video cards because as I wrote at the beginning of the window appears to me HydraGrid. The only way to be able to smoothly changing video adapters is to make it clear to Windows 8.1 that I have a 7690M XT and not a 6700m Series. Then I'm going to also include information about OEM drivers. Thank you

[Q] PIPO W6 SileadTouch.sys needed

Hello,
tldr - can you please provide me file C:\windows\system32\SileadTouch.sys from working PIPO W6?
I was forced to reinstall windows on pipo w6 tablet, and touchscreen did not worked.
there was option to install driver from windows update, which did not work as expected(at about X = 400px no touch events).
I found some win8 instalation image for pipo w6, provided driver worked a bit better, but there was about 100px on bottom of the screen, which did not report any touch feedback.
I have done some registry value tracing, read some linux driver manual. It looks like touchscreen controller needs its firmware before it can report touch events, and this firmware configure the chip so it can skip scanning a node for example. Firmware I have also reports X and Y values swapped so after calibration the screen is completely unusable. Maybe one way to fix this is to manualy swap X and Y coords in calibration registry.
My conclusion is that I need a touch screen firmware, which is located in C:\windows\system32\SileadTouch.sys
Maybe my reseller can help me with this, but his respond frequency is rather slow. So please if there is anyone who own this tablet drop this file somewhere and let a link here
Hifi...

Help me identify this Windows tablet, and touch issue with it.

For touchscreen to work properly I need to provide adequate SileadTouch.fw file that would correspodent to digitizer that is installed in this tablet. Everything else is working (sound, cameras, GPS, battery management, GPU drivers etc.)
In fact, I only need proper SileadTouch.fw file (~100kb), nothing else.
Thank you in advance!

Azpen X1050

I recently purchased an Azpen X1050 2 in 1 tablet. It was bricked, but I managed to get it running properly. I still have one issue, well, two
The first is that the original manufacturer is not responding to any requests, and there is no support for this model on their site anymore.
Does anyone have the same unit, as I cannot find a driver for the touch screen to work properly or alternatively, a driver that would work with the following specs:
Windows 8.1 32 bit
10.6 inch touch screen
Silead GSL 3680 screen chip (this is the problem one, no drivers for it available)
Intel Bay Trail Z3735F Processor
I have seen various threads on this forum where people have had the same problem, but none with this hardware setup.
Any help would be appreciated
Hi, I have some old drivers that I copied before I installed windows 10 on mine - send me a message on facebook. look for me as wemar jonker maybe the ones I have might be able to help with you device
