Hardware Drivers :: ASUS S400CA Brightness Not Adjusting?
Jul 28, 2014
I have an ASUS S400CA running Windows 8.1 (64 bit) and I am having a major issue. When I click Fn + F5/F6 to increase or decrease the brightness, nothing is happening. The slider is stuck beyond a point and the brightness does not change regardless (it is stuck at the highest setting). I have tried to fix this issue by changing brightness settings in the Control Panel, Battery Options, etc. but nothing is working.
I have tried to find previous versions of the Intel HD Graphics 4000 Driver on the Asus website but only find the one I am using. What should I do?

Shouldn't my SSD be viewable somewhere in windows 8.1? It's not unallocated in Disk Utility, just not there, but I can see it in bios, although I can't set it as a boot option.
I'm confused because I thought my OS was on it, but I've been booting without it, so it may have never worked I've had this laptop for a little under 10 months.

I have a new Asus S400CA that came with Windows 8 and I updated to 8.1 out of the box. The computer crashes when it goes into sleep mode probably 1 out of 3 times. I have tried updating all the drivers, including the wireless driver. I have it set to make minidumps but they aren't being created anymore (last one was on 12/5). Usually I get no indication that the computer crashes but it takes a long time to boot back up, although occasionally it will say Windows encountered a problem and has to restart.
I am also getting a ton of Schannel 36888 errors, although I don't know if that's related.

I have recently upgraded hardware on my desktop. The major change is that I installed a new Solid State Drive as my drive C:. I think I also read somewhere that these drives "don't like" being written on too much and that one needs to enable/disable certain OS features for such drives.
So I checked the properties for the drive C in Windows 8 and here's what I got:
As you see "Allow files on this drive to have contents indexed in addition to file properties" is checked.
Does it need to be checked for that drive?
And also, is there anything else that I need to change in the settings to accommodate for the SSD?

since I updated to Windows 8.1. My screen is stuck on dim. It's not dim enough to be unusable, but it's dim enough that I wish I could turn the brightness up. If I use the hardkeys on my keyboard to turn it up or down, the bar will go up and down, but the brightness won't change. Same goes for using the settings charm brightness bar and adjusting via control panel. I've tried updating my display and video drivers, and messing around with the battery "power plan" settings, but after all that it still won't change.

Well I've had my laptop for almost 5 months now, however I did break it and got a screen replacement yesterday. Ever since then my screen seems dim. I've altered all the settings (as explained on other threads) but I still can't get to the centre of the problem. I had no trouble altering my brightness before my screen replacement so I do presume that the screen that the shop fitted wasn't the correct one and therefore a cheap option.

I went and bought a new laptop since my old one was starting to die on me and stuff. It's a Samsung ATIV Book 4, and it's really nice. This is the first hick up I've had with it so far, and I noticed it happening today. I noticed my screen was really dim today as I was using it, so naturally, I use the Fn key to turn it up, but nothing happens. Up in the top left of the screen, it shows a little brightness meter going up and down as I turn it up and down, but nothing changes. I went to the power options menu and tried to adjust it there, and alas, nothing happened. I even tried disabling the display driver and restarting it, but that didn't do anything.

I have a ASUS N56VM laptop, I have upgraded to Windows 8.1 Pro a few months ago (free DreamSpark account) and I can't get USB 3.0 to work at the speeds at which it needs to work. An 3GB ISO which I copy from my HDD to an USB3.0 USB-stick gets a max speed of 25 mb per second. I have already tried everything I could think of, including the following:
Upgrading Intel chipset drivers from ASUS support site (delete old, install new)Upgrading BIOSINF hack (Windows 8 and Intel USB 3.0 Host Controllers | Plugable) "Windows 8* has a native in-box USB 3.0 driver. Intel is not releasing a specific Intel USB 3.0 eXtensible Host Controller Driver for Windows 8."
The driver I have is: imgur: the simple image sharer
The only thing I can think of is maybe mailing ASUS if they can supply a new BIOS revision or mailing Intel if they can supply some new chipset drivers...
EDIT1: A few months back, when the laptop was still running Windows 7, the read/write speeds were "normal", meaning that they were what you would expect from USB 3.0.

I have an Asus P8Z77-V Deluxe. It replaces a motherboard that failed. I have moved the Win 7 image over to the new board using a "restore to other hardware" feature in a backup program. It did not work properly. I am not able to get some drivers to install. For various (and sufficient) reasons I really really don't want to do a clean install. When I first booted, it would not even boot until I used Win PE to repair the boot. Various squirrely things are still wrong. Like not being able to see more than one hard drive. Occasional crashes for no obvious reason.
For an SATA controller when I run update driver or running the Intel INF setup program provided by Asus I get a message:
7 series/C216 SATA AHCI controller 1E02 Also This operation requires an interactive windows station.
I have just run the Intel update program and it says it can't identify a device an I need to contact the board manufacturer.
An alternative I am considering is to install a Win 8 update over the Win 7 telling Win 8 to retain my programs, settings, and data. But I am not sure this will get me where I want to go. My major question about that is will the Win 8 installation be clever enough to use all of the driver files from Asus that I have downloaded (and I point it to) rather than installing something like the incorrect ones currently installed?

I just built a new gaming PC with windows 8 and an msi z87 g45 motherboard. It's amazing, and I installed the Soundblaster and realteck Hd drivers.
The only problem that I'm having is that every time 2 things play at once, the other's volume is lowered. like when I am playing battlefield 4, my gun sound good and then when my friend talks on teamspeak my gun is barely heard for a few seconds afterward. Ive tried changing the "communications- do nothing" thing, but it's not working.

When i try to record from my sound card the volume will randomly go up and down when i try to replay it.
When I try to record from my microphone in the microphone input port it gives an odd problem. Whenever I sustain a note it begins to record just fine but after about 2 seconds the volume adjusts down to about 20% of the original and continues to record. It does this in multiple sounds recording software programs. I have skype turned off and no other microphones hooked up. In the communications tab of the sounds menu I have set it to 'do nothing' but this had no effect. It seems like there is some sort of auto volume leveling thing going on but I cannot find where it would be. I have an HP desktop with beats audio not sure about the sound card otherwise.

I found that f.lux is really useful to your eye when you look pc all day.
However, I found that the light setting doesn't gradually change according to time.
For example, at noon the setting is at the highest peak. So there is different light setting across the day time.
It would be good for night if there is automatic setting for light gradually set to the lowest at midnight.
When this happen, the word and picture look totally different and the nothing come out from the blue colour. I might as well go to sleep and continue work tomorrow.
Is there a way to set a few setting and when the time come, f.lux change the light setting? It may not be fully gradually change but at less there is different in the light setting than have it all same all day.

Recently did a clean install of windows 8 on my Asus K53SV and the function keys work fine except for the brightness keys.Actually, at first i loaded the windows 7 atk package and the brightness keys worked but the volume ones didn't then i got the latest atk package and now the brightness ones don't work (the lower brightness one just dims my monitor a bit and the increase brightness just makes it brighter a bit but doesn't change the brightness value) and the volume ones do.

My roommate has a custom desktop PC, which runs Windows 8 x64.
It can't connect to the internet, or the local network. Windows says limited connection, but ping the router IP yields only lost packages. Solving the error with the automatic error solver, displays problems with the DNS.
The roommate says the connection has worked for a limited time, for about a 1/2 hour, but fell out from time to time.
He has tried to connect to our wireless router, a wireless n d-link dir615. It is set to WPA/WPA2 with AES cipher and PSK.The router runs the newest firmware available, which gives no issues for any other device in the house. (Including Iphones, android phones, old and new N-capable, and N-incapable laptops and desktops).
His PC has an almost unused Asus PCE N15 wireless adapter installed.He says it worked on a different network (He just moved in).
I have tried to give him a static IP and dns, both in windows, and get the router to assign one to him.
I have tried to give him an alternative DNS, e.g. OpenDNS.
I have tried to update his drivers, both the ones provided from Asus, but also one from realtek, since the NIC has a realtek chip on it.

I have an Asus P5QL VM DO montherboard in my homemade PC. This is an older system that I use for testing, so I put my Windows 8 install on it. Unfortunately, the Asus driver installation CD will not run in Win 8, and I am missing one driver which I am unable to locate anywhere. It is for the PCI Simpe Communications Controller.

I have recently built a new computer and installed Windows 8. All was running fine (including USB devices such as iPhone, flash drive etc), however since upgrading to Windows 8.1, none of my USB devices are showing up at all. Oddly, the mouse and keyboard still work.
When I go into the BIOS, all my devices (iPhone, Flash drive, keyboard and mouse etc) all show up in there, so I'm guessing it's a driver/Windows 8.1 issue that I'm missing?
I have been to the ASUS website and downloaded all the drivers I can find, but still no luck.
My motherboard is an "Asus Z97 Pro". I have tried contacting Asus support, but they are completely useless!

I have a CM6730 Asus PC with a P8H61-M PRO/CM6630 motherboard.
I was having problems getting good Graphics performance and the topic of Integrated vs discrete GPU came up, the options in the BIOS were set to use iGPU, since then I do not get the option on boot to enter the BIOS.
I have tried ASUS but they want me to send the unit in for repair.
My rig has Windows 8.1 fully updated.

I have an Asus CM6730 PC, bought in October, which had Windows 8 installed on it.
Everything was fine, until I decided to install the upgrade to Windows 8.1.
After a week or so, my mouse started to freeze up randomly and the only way to log out of the PC was by holding the power button down for several seconds. The next day, I was working on the PC, took a phone call and the machine went into standby mode - but wouldn't come back on when I press a key / moved mouse.
At that point I decided to restore the machine back to factory settings. This was done successfully so I was back to Windows 8. However - my problems have got worse - and now I am at the stage where the PC wont even boot up in Safe Mode - the screen just goes black.
I have read up on a few sites and I believe it could anything from driver related - to a faulty motherboard.

My Q200E Asus laptop came with 4g of memory. I would like to add another 4g's to bring it up to 8g's. I can find no instructions for doing this and am not entirely sure if it can be done. I have removed the back cover and see no memory sticks at all.

I bought an Asus n53sv-eh72 laptop which comes with one USB 3.0 port. In Windows 7 it was working just fine, but after Windows 8 has been installed the USB doesnt work anymore. When I insert any flash drive windows has no reaction.
Ive been trying to find a driver but I couldnt find one that fits.
I know this port works cause Im able to boot windows throw a flash drive. It might be some driver missing.
This is my device manager screenshot.

I have an Asus x202e with I3, Windows 8 64 Bits. The defect is that the battery does not detect. Here's what I did: I disconnected the battery, I pressed the power button 30 seconds and not fixed. I reset BIOS F2, F9 and F10 and again not repaired. I uninstalled the Microsoft ACPI method battery and nothing. Do you think that a BIOS update will fix the fault? Mention that no longer turn on the battery.

I'm trying to confirm whether or not TRIM is actually working on my system and I can't find any definitive answers.
I'm on a new Asus G750JZ-DB73, which has dual SanDisk 128 GB SSDs in RAID0. I've heard that TRIM was incompatible with RAID, but I've also seen recent reports claiming that newer drives or motherboards or whatever did allow for TRIM with RAID drives. My knowledge if techese is limited, so I'm unsure what to believe.
Secondly, I've encrypted my SSD(s) using DiskCryptor without issue, and DiskCryptor claims full compatibility with both RAID and TRIM.
Here's where I get confused. Both CrystalDiskInfo and the "fsutil behavior query DisableDeleteNotify" command in Command Prompt indicate that TRIM is enabled on my system. However, when I use TRIMcheck, I'm informed that TRIM doesn't appear to be working.
How can I conclusively verify if TRIM is working for me? And if it isn't, is there a way to activate it on my system?
EDIT: The SSD is a SanDisk SD5SE2256G1002E.

I've recently installed Windows 8 on an Asus X201E. There is an audible constant disk trashing, although the HDD LED doesn't blink & the Performance monitor in the task manager also doesn't indicate any excessive disk access (literally 0% when nothing is going on). What could cause this? Besides the annoying sound, I'm worried about the disk wearing out.

Asus Vivobook. It was running fine last night, but today it was a bit slow to respond. I eventually restarted it and it told me I have disk problems. Now I'm stuck on a black screen with the Asus logo that reads "Repairing disk errors. This might take over an hour to complete."
It's been this way for multiple hours now. I'm going to leave it overnight and hope it repairs, but, if it doesn't, is there anyway to recover my files? I have some important stuff backed up online, but I haven't backed up in a bit over a month and I don't want to lose my files. Most forums tell me to reinstall Windows 8? Would that make me lose my files, though, and how can I do that if I can't get past this error page?

I have an Asus laptop with Windows 8 64-Bit on it and I uninstalled AsusDVD after having some issues with it. After I did this my laptop no longer allowed me to play DVDs. Despite having Windows Media Player, which I know plays DVDs since I have it on my desktop.
Is there a way that I can change some settings to use Windows Media Player? When I open "Autoplay" Windows Media Player is not an option to play it on and there isn't anything else on my laptop that can play it. I tried a few different free DVD players, but none were able to play them for some reason.
How I can get Windows Media Player to play DVDs or suggest a free software that I can download that will play DVDs?

I have a Asus T100 tablet with 32GB SSD. I bought a 64GB SD card to augment the storage on the tablet. The problem I am having is that the SD card disconnects after a few minutes of no activity, I then have to take it out of the tablet and pout it back in. I then have the folder in my C Drive again. How do I prevent the SD card from disconnecting so that I can use it as additional storage?
