Sony Vaio FZ Series - LCD brightness

Hi All,
I have recently bought a Sony VAIO FZ11S and I've successfully installed Archlinux:
Fully working:
- CPU Scaling (using cpudyn)
- Multimedia keys (mute, volume up/down, play/stop, etc. using Xmodmap)
- Wireless (using iwl3945. Can't connect with AP with hidden SSID)
- Nvidia GeForce 8400M (using latest nvidia drivers with stock arch kernel 2.6.23)
- Audio (after adding 'options snd-hda-intel model=vaio' to /etc/modprobe.conf. MIC not tested yet)
Untested:
- bluetooth
- SD/MS card reader
- Video camera
NOT WORKING:
- LCD brightness adjustment: FN+F5/F6 are detected correctly by acpid but nothing happens. I'm using the module sony-laptop included with kernel 2.6. Folder /sys/class/backlight is empty. I can use nvidia-settings to change COLOR BRIGHTNESS but this is NOT a good solution IMHO. I'd like to get the same capabilities I get running Windows Vista. (change LCD backlight).
I've read somewhere it is a problem common to all laptop with the same NVIDIA videocard. Does anyone know a fix for this? I've also tried with latest nvidia beta drivers with no success.
- Hibernate/suspend. I tried with pm-tools to suspend/hibernate laptop but nothing is working correctly. I didn't investigate further. Has anyone got a quick solution for this?

I recently bought a Sony FZ180, almost identical stats and hardware.
I tried all the same suggestions, which worked fine on my old laptop, but will not for this one. If anyone can think of another method to control the backlight I would be grateful.
Also, I tested the SD slot, the TI driver recognizes when a card is inserted, but no devices or mount-points are created.
tifm_core: MMC/SD card detected in socket 0:1
tifm0 : demand removing card from socket 0:1
(The second line is from me removing the card, not a defective slot.)
Everything else works great, though. Arch boots to a full KDE desktop much, much faster than my cleaned-up vista partition. I'm really happy overall.

Upgrading Sony Vaio E Series HDD to SSD

I want to upgrade my Sony Vaio E Series Hard drive to a SSD and was wondering what type of SSD I should get since ive heard that certain ones will not work with this laptop.
Thanks

Any SSD should work fine in that notebook. I would reccommend a 256 GB Crucial M4. All you have to do is make recovery discs with the Sony system software, copy all your personal files, favorites, and preferences to a flash drive, have the SSD installed, and then use the recovery discs to rebuild your system. Once you do all that, you just copy your stuff off the flash drive and install all the software updates.

Can IInstall OS X Snow leopard on my Sony VAIO E-series?

I just recently well literally today got delivered my OS X Snow leopard installation disk and I was wondering is there a way to install Snow leopard on my Sony VAIO E series SVE1512K1EB because I want to make a hackintosh :3 Now I know Apple is against this an all but I just would like to experiment. when I openthis up I only see this (see photo below)
Now as you can see from the pic I it says bootcamp and stuff and the setup application did nothing to be honest. Have I actually bought the
official Snow leopard OS because the DVD only
says 800Mb which is nothing and a mac OS is
normally 5GB. Can I have some help? because
Miscrosoft support said come here lol and I really want to install this cool OS on my partitioned HDD
specially named Snow leopard lol. I have tried fooling around with the BIOS and I have restarted and seen if the PC said "do you want to install..." but no luck and the disk drive does rev up like something is going one but nothing. Can some one please just help me? :3
Here is another picture of my laptop and the OS ontop.

No, there is no way to do this. OS X drivers will not be compatible, and it violates the OS X license.
This is an Apple site, so we will not help you with hackintoshes. You need to seek help elsewhere.

Does the SONY VAIO F Series SVF15412CXB support dual channel memory?

Does the SONY VAIO F Series SVF15412CXB support dual channel memory? Or does it only have one slot?
I'm curious if I can put a second stick of RAM in there for dual channel performance.

Hi Mark, Thanks for the response. Can you please double check that for me, or post a link to the documentation where you saw that? I asked this question on Newegg, too, and one of the respondants heard differently:
"i found out from sony that there is only 1 slot cause i was gonna get 1 more 4GB stick of ram for 8Gb. So iwas upset about that cause i have to get 8GB now and it costs 100$ for an 8Gb stick of ram on ebay. So this ram is expensive. So im sticking with 4Gb for now. This is a very good laptop though. I use it primarily for minecarft and steam and i get around 100 fps on minecraft so its good. I hope this helps." It's just confusing because other laptop advertisments I've seen openly stated how many RAM slots the computer had and how many were used upon purchase. I haven't found anything like that which makes me think that there's only one slot for RAM. Thanks,Gremark

Anybody know why my Sony Vaio S series won't recognise my iPhone 3GS ?

I just bought a Sony Vaio S with Intel i5 chip, however when i plug in my iPhone 3GS absolutely nothing happens. The phone doesn't even charge - I've checked the cable with my old Dell and it works . I've downloaded the latest iTunes and can't seem to work out why I'm getting zilch from the laptop? I've tried all 3 USBs on the thing but still no good.
I'm pretty tech-stupid but would appreciate any help .Thanks

Can i change the processor ? Sony Vaio E Series

Hello I have a Sony Vaio Model sve1513b1ewIt has a Intel Pentium 2020M Processor Can i be able to change the processor to a i3 or i5 ?

Hi gasspari,
Thank you for considering Sony Community!
We do not advise Vaio users to upgrade or modify certain parts of their units, especially the processor. It is still possible but we cannot guarantee that it will work without any issues. Another thing is, your Vaio SVE1513B1EW is not a U.S. model and we have limited information about your computer.
For further assistance, or any other concern, we kindly recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/.
Hope the link helps.

Sony Vaio F Series Screen Colors Brushed Out

Hi, Im running Windows 7 Home Premium on my Vaio VPCF235FG, I did windows recovery but the colors seem brushed out. I did update my Nvedia Driver but still same issue. I did some researches on google and I found out it has to do with Monitor LED not getting enough power to give full color depth something like that, but I dont know which driver or software patch I have to download to fix this issue. Please help

Hi Hu22aM,
Welcome To Sony Community!
We're sorry to hear this. I have few questions for you to help me understand what's really going on.
When did it star to happen?
May I know why you needed to do windows recovery? Is this when the computer went back to factory setting?
If so how did you do it, was it using a recovery disc or through the partition ?
Let's try to isolate the issue
Turn of the laptop
Go to BIOS by repeatedly hitting F2 right after you turn it on (was the color brushed out)
If the screen color is the same then it means that it's a hardware issue (repair is needed
If screen if normal, then go to the Sony website and update the drivers and software.
Unfortunately, we are unable to assist customers outside of the US. We kindly recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/.

Brightness not adjustable in Windows 8.1 Sony Vaio (formerly sleep issue)

AAAAAARGH. Whenever I hear the word VAIO my blood pressure rises. Model: VPCYB13KX/P (P=Pink) but the problem seems to be a universal oneMajor problems: cannot change brightness at all, closing the lid puts computer in non-responsive but 100% CPU state (judging by the CPU cooler fan turning on to max and enough heat radiating from the base of the laptop to fry an egg)OS: Windows 8.1 upgraded from a clean install of Windows 8 64 bit So, in my case I clean installed Windows 8 followed by 8.1. Vaio "care" (if that's what you want to call it) and all the ancillary junk was installed as well (much of it removed in trouble shooting). Before I did trouble shooting I had four major problems:1 FN keys (F5/F6) did not adjust brightness at all (still broken, and officially broken for the VPCYB series according to http://esupport.sony.com/US/p/support-info.pl?info_id=1380)2 FN keys (F3/F4) did not adjust sound (fixed, not sure when)3 Brightness could not be changed AT ALL (broken, fixed and now broken again by solution to sleep problem)4 Closing the laptop's lid would cause the computer to go into a "frozen" but active state out of which it couldn't be woken up (fixed by steps at end of post)5 Complaint during boot about missing file (see http://community.sony.com/t5/Windows-8/iolorgdf32-program-can-not-be-found-Skipping-Autocheck/td-p/161333 for someone else's description of problem) (not fixed; not bothered to try... seems like a minor problem compared to everything else)6 mf110u DLL missing dialogue box upon startup (see http://answers.microsoft.com/en-us/windows/forum/windows_8-windows_update/mfc110udll-missing-windows-8-pro-updates-wont/9596536f-a405-4b1e-b8cf-b06e28b7fea4?msgId=28e1af2b-d536-4258-aea2-a1155cc6464b) (fixed) Re: 3 brightness. Before the sleep fix (billed as a brightness fix) was applied I was able to adjust brightness using the Windows brightness controls (one in the new interface and one in the desktop/traditional interface). Now I can't. Re: 5 and 6 My guess is that #5 and #6 have to do with the Vaio Care software (which seems to be someone else's software repackaged?). This laptop has been a support headache from day one, even under the 'clean' OEM Windows 7 Home Premium with Vaio drivers and software being the culprits 95% of the time (terrible QAQC). Until very recently I had problems with the wifi cutting out daily in Windows 7 Home Premium (only fixed when I clean installed Ultimate and used non-Sony driver for wifi... I should've stuck with 7 Ultimate and not boethered with 8). What others have been told would correct their brightness problem fixed my sleep problem (I can close the lid now) but it broke my brightness adjustment ability. I'm now stuck at 100% no matter what I do. PS These are the instructions for how to fix the brightness problem (and, to reiterate, it broke my brightness solution but fixed my sleep problem): 1.Launch Task Manager
2.Terminate two tasks
•esrv.exe
•esrv_svc.exe
3.Delete “sony_acpi_battery_input.dll” Under “C:\Program Files\Sony\VAIO Care\ESRV\sony_acpi_battery_input.dll”
4.Restart PC So, if anyone has a suggestion about how to get brightness working without breaking sleep please let me know. If I don't have any success fixing this I'm simply going to downgrade the laptop to Windows 7 Ultimate again and transfer my Windows 8 licence to my home built desktop machine (I was going to pick up a second licence but maybe I won't bother since I'll only need one).

I did try that IIRC but no luck. I've simply given up and gone back to Windows 7 because I don't have the luxury of devoting time to re-installing software when I've got toddlers screaming for my attention and work taking up the rest of my time. I haven't installed a single piece of Sony software on my Windows 7 install and so far only two things were not working: brightness control and a broken wifi driver. I fixed the driver (Sony doesn't provide a fix for the faulty wifi driver for the VPCYB13KX, nor does Microsoft) by installing a driver from the web (care of Atheros.cz). And, i haven't bothered to go after the brightness control because it's not as pressing an issue as the faulty wifi driver. Plus, I don't have any of the Sony bloatware slowing things down (installing an SSD at the same time may have had something to do with the speed up ;-). Plus, in many ways going back to Windows 7 simplifies my life big time since it is a computer that's being used by two people and Windows 8.1 makes accomodating the work flow of two separate people in one account difficult. Tangent... And, it means that at least one computer isn't subject to the prying eyes of Microsoft Live. I am becoming really leery of the amount of information that private companies (which means there is zero transparency) are able to collect and sell about private individuals through Windows 8.1, Mac OS X 10.9 and Google OS. If you happen to allow the wrong settings these OSes are able to track and store phenomenal levels of personal information (which police would never be able to find out about you without a warrant, let alone store in perpetuity). And, who knows if these OSes even honour your opt-outs. Or, if through coding errors they still continue to collect the data anyway.

Sony VAIO VGN-FW11E - can't set brightness

Hello everyone!
I have really annoying problem with my laptop - setting brightness just don't work. I have tested many others distributions and this work only under Ubuntu 9.10 beta. I think that is connected with this. How can I use this patch in arch?
Laptop: Sony VAIO VGN-FW11E
Graphic card: ATI Radeon HD3470
I'm sorry for my english but people in polish forum just can't help me ;p

@B I'm not able to make so specific changes like you said. I can build something from AUR, sometimes also make some changes to PKBUILD's but doing something with dsdt is to hard for me.
@litemotiv
Do you think I shoud compile new kernel with new sony-laptop module inside?
hmm, i'm not certain that will fix it for you..
do you already have a fixed dsdt for your laptop? if you do, the best way is to compile a kernel with these lines added to the kernel config file:
CONFIG_STANDALONE=n
CONFIG_ACPI_CUSTOM_DSDT=y
CONFIG_ACPI_CUSTOM_DSDT_FILE="DSDT.hex"
that will definitely fix the brightness issue. the sony-laptop module is built by default, so you don't have to compile that specifically (the module is needed to get the function-keys on your keyboard working, it shouldn't have any influence on the brightness itself).
if you don't have a custom dsdt yet, you need to make one following the instructions on the vaiobuntu blog. it's a bit daunting at first, but i assure you that it's doable.

LCD Brightness, sony_acpi from aur won't build

I'm using a Sony VAIO vgn-sz430n, and the Fn keys won't work to change the brightness. I'm not so concerned about the Fn keys, for I've seen tons of documentation to get those working with xbindkeys, xmonad, openbox, etc. and I will worry about that later.
Most importantly, I cannot change the screen brightness. Xbacklight does not do anything, laptop-mode-tools and gnome/xfce4-power-manager do nothing. The screen brightness is always at the maximum.
I have an nvidia Geforce Go 7400 card with the proprietary nvidia driver
I read that I need the sony_acpi module, and I've been trying to install it from the AUR, but I get errors and I don't know what to do. I've tried with yaourt and manually. Here are the results from yaourt:

The strange thing is this works in other distributions, such as Ubuntu. If I fired up a live cd and tested out my Fn keys, the brightness would change and there would be an on screen display for feedback.
What is Ubuntu doing, specifically, that Arch is not doing? Is there any way I could load an ubuntu live cd and then find what files/programs/modules/whatever are in place that allow brightness changes? Does anyone know this offhand?
Help!

I have Sony Vaio VGN-FZ38M with Nvidia 8400M GT. I used package 'nvclock' (it is in repo) to control lcd brightness, here site with more info: NVClock. Some time ago I also configured Fn keys to work with it (on Ubuntu), but on Arch I didn't manged but I didn't try hard (in general i don't need, my laptop is stationary all the time). Solution I've found somwehere in Ubuntu forums.

[SOLVED] ACPI power issues with Sony Vaio Pro 13

tl;dr backstory:
Sony VAIO Pro 13 (SVP13215CDB) laptop was working great (Win 8.1).
Installed Win10 Tech Preview. A week later, it started going to sleep randomly and on certain key-presses (perhaps after performing Sony Vaio Software updates. I'm not 100% sure). I wiped all partitions installing Win7 in legacy mode. It still went to sleep randomly.
I restored to factory default Win8.1 with Sony Vaio software up-to-date. It still went to sleep randomly.
Took it to an electronics repair shop, to see if they could fix it, and they said it can't be fixed in any way without replacing motherboard, but that's basically a new laptop.
So I turned to Arch Linux.
I have completed the basic install from the Wiki, and it no longer sleeps/shuts down randomly, but it will gracefully shutdown when certain events/keypresses occur.
I installed acpid and used "acpi_listen >> acpi.log" to determine what causes the system to perform a graceful shutdown. Here is the result of acpi.log (each line was a shutdown event):
button/power PBTN 00000080 00000000 # Unplugged power adapter.
button/power PBTN 00000080 00000000 # Running on battery and idle. Perhaps battery percent update caused this?
button/power PBTN 00000080 00000000 # Plugged in power adapter.
button/power PBTN 00000080 00000000 # Fn-F1 Touchpad Disable
button/power PBTN 00000080 00000000 # Fn-F5 Brightness Down
button/power PBTN 00000080 00000000 # Fn-F6 Brightness Up
button/power PBTN 00000080 00000000 # Fn-F7 LCD/External Display
button/power PBTN 00000080 00000000 # Fn-1 (Weird. It has no extra function).
As you can see, they all seem to trigger the same shutdown event.
I have seen on other posts that these ACPI signals can be disabled or assigned to other commands, which would be an acceptable workaround if it stops my laptop from erroneously shutting down. Is this doable?
Also, I was not able to reflash the Sony VAIO firmware when using Windows, as Sony's package software is amazing wouldn't allow flashing an equal or lesser firmware version. Perhaps there is a way in Arch to force a reflash if I can get my hands on the firmware blob?
Thanks .

linux /boot/vmlinuz-linux root=UUID=<UUID here> rw quiet acpi=off
Like this?
I did that, and it disabled my laptop keyboard entirely. In doing so, it disables the key-presses that would normally shutdown the laptop, including the power button. So the only way to shut it down is a hard shutdown via long-press of the power button. Thanks, though.
Update: Issue Solved. I will update post tonight. Flashing the BIOS again resolved the ACPI issues.

Vaio E series - Cooling Fan noise

Hello, 2 weeks ago I bought Vaio E series. I was very excited that I will have Vaio laptop. It was like my dream wish. According to our standard, we are poor country and the Vaio laptops are extremely expensive. But, Vaio laptops are know for high quallity laptops and great support from Sony. So, I bought it. I am very satisfied with the quality. But I have one problem. The cooling fan is making a lot of noise even the CPU usage its 10 %. I have the latest BIOS version. So, Sony I am expecting from you to release a new BIOS update fixing this issue.. I dont want to start thinking that I pay a lot of money only for the name. With that money I could buy a more powerful machine but I put my trust in Sony. The model number is Model # SVE17122CXB. PS. Don't say that I should go to service center because they can do nothing. I am an IT student and I know how this stuff works. And I dont want the fact that the new laptop will be repaired. So the only solution is BIOS update. Sony, do not make me regret that I have chosen you before other brands.
I am expecting a positive feedback.

t0n1,
Engineering came back saying that fan speed control is not supported on the SVE17 hardware so there is no way on this model to control the fan speed manually. I apologize for suggesting this initially, at the time I did not have your exact model at my desk but instead I had a very similar one (SVE14A)
I also received two SVE17 notebooks and both have extremely quiet fan (especially if CPU usage is very low). Loud fan noise is not a characteristic of this model.
If you feel that the fan on your SVE17 is abnormally loud, then you have two options at this point:
1) You can make a audio/video recording of this fan noise and post it for me to review; after that i can try to give you more suggestions or let you know if this is in fact normal or not. At this time you do not mention that your computer is shutting off, so the unit is not overheating.
2) Or you can consider service. (I realize you initially refused service in your original post, but sometimes some new thermal sheets or re-seating of the heat-sink can address these issues.
